Human Beings are Hardwired for Consciousness.
Did you know the part of your brain we think Consciousness comes from is called the 'Rostral Anterior Cingulate Cortex' that plays a key role in experiencing of emotions,..... and reward-based decision-making and learning, including motivation, cost-benefit calculation, as well as conflict and error monitoring.
It also determines whether our future will be one of clear-blue skies or dark stormy clouds.
This is because Optimism and Pessimism are not hardwired in our brain, and we as the Gods we are determine if we use cognitive behavioral techniques to overcome our natural tendencies towards doom and gloom.
So what do you think you want to do, dwell on mistakes of the past and continue to pick at the scab, or do you make a fresh start, and leave your mistakes in the past where they really belong?
Because we do know our lives are better when we choose Optimism, and that's where consciousness comes into play, because it is hardwired in our brain, we just have to realize it is we who are the God, and we make all of the decisions in our livelihood, not anything outside of ourselves like the Gods man creates to make us think THEY are in charge, because they aren't, we are.
But as I've said those choices aren't Hardwired in our brains, and we can choose to let religions God make all of our decisions for us.
Or we can choose to follow our heart, through your brains consciousness,.... the choice is entirely up to YOU!

"Just a cold" that changes the structure and mass of your brain
By Nikhil Prasad
Medical News: A groundbreaking study from researchers at the University of California, Los Angeles (UCLA)-USA has shed light on how Long COVID is linked to structural changes in the brain caused by SARS-CoV-2. By using advanced imaging techniques, the team discovered structural changes in the brains of individuals with Long COVID, including increased cortical thickness and gray matter volume in specific regions. This Medical News report will explore the study's key findings, its implications for understanding Long COVID, and what it means for patients suffering from this persistent condition.
Understanding the Research Approach The study involved participants from the UCLA hospital and broader Los Angeles community, with 36 individuals ranging in age from 20 to 67. Among them, 15 had Long COVID symptoms, while others were used as healthy controls. Researchers utilized structural magnetic resonance imaging (MRI) to compare brain differences between these groups. The study focused on specific brain regions, such as the dorsolateral prefrontal cortex (DLPFC) and the cingulate gyrus, which are known to be involved in cognitive and emotional processes. These areas were chosen because they are susceptible to inflammation and have been linked to neuropsychiatric symptoms.
To assess participants' cognitive and emotional health, tools like the Montreal Cognitive Assessment (MoCA) and the Hamilton Anxiety and Depression scales were used. The imaging data were processed using specialized software to measure cortical thickness and gray matter volume, providing a detailed look at the brain's structural changes.
Key Study Findings The study revealed several critical findings that deepen our understanding of Long COVID's impact on the brain. Participants with Long COVID showed:
-Increased Cortical Thickness: Regions such as the caudal anterior cingulate, posterior cingulate, and rostral middle frontal gyrus exhibited significantly higher cortical thickness compared to controls.
-Higher Gray Matter Volume: In areas like the posterior and isthmus cingulate gyri, Long COVID patients had greater gray matter volume.
Interestingly, these structural changes were associated with the severity of clinical symptoms. For example, higher thickness in the cingulate regions correlated with more severe chronic illness scores, while increased insular thickness was linked to anxiety levels.
Such changes suggest that Long COVID might lead to either swelling due to inflammation or compensatory mechanisms like neurogenesis to counteract damage.
How This Study Compares with Previous Research While most COVID-19-related brain studies have shown reductions in gray matter and cortical thickness, this research indicates an increase in these metrics for Long COVID pa tients. Prior studies focused on acute COVID cases often revealed brain shrinkage and cognitive decline. In contrast, this study highlights that Long COVID might involve unique mechanisms, such as prolonged inflammation or a compensatory response to earlier damage.
Implications for Patients and Healthcare Providers These findings are crucial for both patients and healthcare professionals. They suggest that the persistent symptoms of Long COVID, such as brain fog, fatigue, and anxiety, could have a physical basis in brain structure changes. Recognizing this connection can lead to better-targeted treatments and interventions.
The Future of Long COVID Research While this study offers valuable insights, it also leaves many questions unanswered. For example, are these brain changes reversible? Do they worsen over time? The researchers acknowledge the study's limitations, including its small sample size and lack of longitudinal data. Future studies should aim to include larger, more diverse populations and examine changes over time to build a clearer picture of Long COVID's effects.
Conclusions This research from UCLA represents a significant step forward in understanding the neurological impacts of Long COVID. The observed increases in cortical thickness and gray matter volume in certain brain regions provide strong evidence that Long COVID involves measurable structural brain changes. These findings offer hope that by identifying the physical manifestations of this condition, we can develop more effective treatments to alleviate its symptoms. However, the path forward requires continued research to uncover the full extent of these changes and their implications.
The study emphasizes the importance of addressing neuropsychiatric symptoms in Long COVID patients and highlights the need for comprehensive care that includes both physical and mental health support. As we move forward, it is vital to integrate these insights into public health strategies to help those affected by this debilitating condition.
The study findings were published in the peer-reviewed journal: Frontiers in Psychiatry. www.frontiersin.org/journals/psychiatry/articles/10.3389/fpsyt.2024.1412020/full

[ID: A picture of a mockup article displayed in CatCo's website. In the top center there is a screenshot of season 1 episode 20 where you can see National City citizens walking through the streets at night while being mind controlled. Atop the image in the left corner there is a red rectangle with white letters spelling 'News' in all caps. Below the image there is another red rectangle with the word News inside it, but this time it's a lighter red and the letters are red. Beside the rectangle in all caps it says, 'National City' in black letters.
Title of the article: What was Myriad?
By Cat Grant May 25th, 2016. The words 'Cat Grant' are red and inside a light red rectangle.
Body of the article: Yesterday National City was attacked. The whole city was mind controlled with a device called Myriad. This device is of alien origin, as Supergirl informs us. It was made with the intention to be used only as a last resource in case of a global crisis. It was made with the intention to save a planet. This planet was Krypton. The culprit of yesterday's attack was a group of rogue kryptonians, their mission to save Earth from humans' self-destructive tendencies.
Myriad works by shutting down the connection between the amygdala and the rostral anterior cingulate cortex. The parts of the human brain that give rise to optimism and hope. Here I quote a citizen about their experience under Myriad: "Under Myriad, I could see, I could hear, but it was like I was a complete stranger to myself." Supergirl's speech saved us all by giving back what we needed the most. Hope. End ID]

Introduction
In the last decade, there has been a rapid increase in the numbers of young people with gender dysphoria (GD youth) presenting to health services (Kaltiala et al., 2020). There has also been a marked change in the treatment approach. The previous “common practice” of providing psychosocial care only to those under 18 or 21 years (Smith et al., 2001) has largely been replaced by the gender affirmative treatment approach (GAT), which for adolescents includes hormonal and surgical interventions (Coleman et al., 2022). However, as a recent review concluded, evidence on the appropriate management of youth with gender incongruence and dysphoria is inconclusive and has major knowledge gaps (Cass, 2022). Previous papers have discussed that the weaknesses of the studies investigating the efficacy of GAT for GD youth mean they are at high risk of bias and confounding and, thus, provide very low certainty evidence (Clayton, 2022a, b; Levine et al., 2022). To date, however, there has been little discussion of the inability of these studies to differentiate specific treatment effects from placebo effects. Of note, the term “placebo effect” is no longer used to just simply refer to the clinical response following inert medication; rather, it describes the beneficial effects attributable to the brain-mind responses evoked by the treatment context rather than the specific intervention (Wager & Atlas, 2015). This Letter argues that the current treatment approach for GD youth presents a perfect storm environment for the placebo effect. This raises complex clinical and research issues that require attention and debate.
A Brief Introduction to the Contemporary Concept of the Placebo Effect
The term “placebo effect” can be used variably by different authors. As recently defined in a consensus statement, placebo (beneficial) and nocebo (deleterious) effects occur in clinical or research contexts and are due to psychobiological mechanisms evoked by the treatment (or research) context rather than any specific effect of the intervention. Importantly, placebo and nocebo effects not only occur during the prescription of placebo (inert) pills, but they can also substantially modulate the efficacy and tolerability of active medical treatments (Evers et al., 2018).
The therapeutic ritual, the encounter between a sick person and a clinician, is a powerful psychosocial event. Clinicians, particularly physicians, are our society’s designated healers and their prestige, status, and authority help engender patients’ trust and expectations of relief from suffering (Benedetti, 2021a). Positive clinician–patient interactions are associated with decreased anxiety and increased hope. Complex neurobiological mechanisms are implicated in the placebo effect, including release of neurotransmitters (e.g., endorphins, cannabinoids, dopamine, and oxytocin) and activation of specific areas of the brain (e.g., the prefrontal cortex, anterior insula, rostral anterior cingulate cortex, and the amygdala) (Colloca & Barsky, 2020; Kaptchuk & Miller, 2015). These changes are associated with an increased sense of well-being. They also impact on cardiovascular, respiratory, immune, and endocrine functioning, all of which may contribute to patients’ clinical improvement (Enck et al., 2013; Wager & Atlas, 2015).
Several unconscious psychological mechanisms, including classical conditioning and social learning, play a role in the placebo effect (Benedetti, 2021a). In clinical trials, where patients communicate with each other, a process of social observational learning may be associated with emotional contagion and, thus, placebo and nocebo effects (Benedetti, 2013). The media and social media may also foster these effects and contribute to the dissemination of symptoms and illness throughout the general population (Colloca & Barsky, 2020).
Expectation of outcome is a principal mechanism of the placebo effect and anything that increases patients’ expectations is potentially capable of boosting placebo effects (Evers et al., 2018). Although research has demonstrated that changes in physiological parameters may occur following placebo administration (Wager & Atlas, 2015), these response expectations have been particularly noted in patient-reported outcomes, such as anxiety, pain, life satisfaction, and mood. Expectations and cognitive readjustment can lead to behavioral changes, such as resuming normal daily activities, which can be observer rated. Physicians’ status, whether through the general position given to them in society or through individual personality factors, may contribute to such expectations of benefit. This type of phenomenon has sometimes been termed prestige suggestion. The “Hawthorne effect” describes the phenomenon where clinical trial patients’ improvements may occur because they are being observed and given special attention. A patient who is part of a study, receiving special attention, and with motivated clinicians, who are invested in the benefits of the treatment under study, is likely to have higher expectations of therapeutic benefits (Benedetti, 2021a).
Placebo-induced improvements are real and can be robust and long lasting (Benedetti, 2021b; Wager & Atlas, 2015). Individual patient factors, such as personality and genetics, may be associated with placebo responsiveness (Benedetti, 2021a). The particular illness is also relevant. For example, although placebo treatment can impact symptoms of cancer, there is no evidence that placebos can shrink tumors (Benedetti, 2021b; Kaptchuk & Miller, 2015). However, there is evidence that placebos can act as long-lasting and effective treatments for depression and various pain conditions, such as migraine and osteoarthritic knee pain (Kam-Hansen et al., 2014; Kirsch, 2019; Previtali et al., 2021). Further, some research suggests adherence to placebo medication, particularly in cardiac disease, may be associated with reduced mortality (Wager & Atlas, 2015).
The Research Setting versus the Clinical Practice Setting
Research into new medical treatments aims to control for placebo effects, and this helps ensure true evaluation of the treatment’s efficacy (Enck et al., 2013). The double-blind randomized controlled trial (DBRCT), although not perfect, is the current gold standard for determining the efficacy and safety of a treatment. The DBRCT study design evolved over several centuries and became widely accepted practice in the mid-twentieth century (Lilienfeld, 1982). Of note, the term “blind” is thought to have originated in eighteenth-century France when blindfolds were used to disprove Anton Mesmer’s “animal magnetism” theory and the mesmerism craze of that era (Kaptchuk, 1998). Well-designed DBRCTs minimize the impact of bias, confounding and placebo effects on findings and are the best type of study for determining whether there is a causal relationship between an intervention and an effect (Enck et al., 2013; Kabisch et al., 2011).
The reader may wonder about this requirement of differentiating placebo effects from the specific effects of an intervention and ask: If the patient improves, does it really matter why? Yes, it does, particularly for treatments that have significant risk of adverse effects. There are also broader problems raised by relying on the placebo effect. Consider prescribing antibiotics for viral infections. The patient may experience clinical benefit through a placebo effect. However, not only may some patients experience serious adverse drug reactions, but the health of the whole population is imperiled by the problem of antibiotic resistance (Llor & Bjerrum, 2014). Furthermore, informed consent is an ethical pillar of modern medicine and requires clinician honesty and transparency. Clinicians deceptively utilizing placebo treatments do not meet this requirement (Barnhill, 2012; Kaldjian & Pilkington, 2021). A medical profession that does little to distinguish placebo effects from specific treatment effects risks becoming little different from pseudoscience and the quackery that dominated medicine of past times, with likely resulting decline in public trust and deterioration in patient outcomes (Benedetti, 2021a).
Ideally, in evidence-based medicine, a new treatment undergoes rigorous research and has reasonable evidence of benefit prior to being introduced as routine treatment (although ongoing further research often continues). Clinicians can then reasonably harness and enhance the placebo effect to improve outcomes (Enck et al., 2013). A placebo effect enhancing clinical setting, in which warm and empathic clinicians provide supportive and attentive health care, creates a “therapeutic bias” in patients, giving them hope and expectation of improvement. This is “legitimate” so long as it is done without deception and in a manner consistent with informed consent, trust, and transparency (Kaptchuk & Miller, 2015).
This ideal of clinical interventions having solid evidence of efficacy before being introduced as routine practice is not always a reality. Sometimes, it is more of a situation where the “cart” of clinical practice precedes the “horse” of rigorous research evidence. Then, this catch-up research may be undertaken in a placebo effect-enhancing clinical environment, rather than a placebo effect-controlled research environment. Such situations, especially when DBRCT are not possible, present the researcher and clinician with complex research and clinical conundrums. Some of these will now be explored using the example of the treatment of youth with gender dysphoria.
A Brief Introduction to the Gender-Affirming Treatment Model for Children and Adolescents with Gender Dysphoria
Gender dysphoria is a term used to describe the distress that is frequently felt by people whose sense of gender is incongruent with their natal sex (these people may also self-identify as transgender) and if the dysphoria is intense and persistent, alongside several other features, a DSM-5 diagnosis of gender dysphoria may be made (American Psychiatric Association, 2013). There has been a sharp rise in the numbers of children and adolescents identifying as transgender and being diagnosed with gender dysphoria (Kaltiala et al., 2020; Tollit et al., 2021; Wood et al., 2013). Many are natal sex females presenting in adolescence, and many have neurodevelopmental and psychiatric disorders (Kaltiala-Heino et al., 2018; Tollit et al., 2021; Zucker, 2019). International guidelines and child and adolescent gender clinics (CAGCs) commonly endorse a gender affirmative treatment approach (GAT) (Coleman et al., 2022; Hembree et al., 2017; Olson-Kennedy et al., 2019; Telfer et al., 2018). Key components of GAT include affirmation of a youth’s stated gender identity, facilitation of early childhood social transition, provision of puberty blockers to prevent the pubertal changes consistent with natal sex, and use of cross-sex hormones (CSH) and surgical interventions to align physical characteristics with gender identity (Ehrensaft, 2017; Rosenthal, 2021). This Letter’s discussion focuses primarily on the medical (puberty blockers and cross-sex hormones) and surgical elements of GAT.
GAT can achieve some of the desired masculine or feminine appearance outcomes, but the main arguments used to support the use of these treatments in GD youth are that they improve short- and long-term mental health and quality-of-life outcomes. However, this claim is only underpinned by low-quality (mostly short-term, uncontrolled, observational) studies, which provide very low certainty evidence, complemented by expert opinion (Clayton, 2022a; Hembree et al., 2017; NICE, 2020a,b; Rosenthal, 2021). No randomized controlled trials (RCTs), including none using the previous treatment approach as a comparative, have been undertaken. This low-quality evidence for the efficacy of GAT is of particular concern given the potential risks associated with GAT.
Risks of Gender-Affirming Medical and Surgical Treatments
Impaired fertility is a risk of cross-sex hormones, and the extent of reversibility of this is unclear (Cheng et al., 2019; Hembree et al., 2017). If puberty blockers are commenced in early puberty and followed by cross-sex hormones, there are no proven methods of fertility preservation (Bangalore Krishna et al., 2019). Surgeries, such as gonadectomies and most genital surgeries, will result in permanent sterility. These impaired fertility and sterility outcomes are important because, firstly, as Cheng et al. (2019) reported, the widespread assumption that many transgender people do not want to have biological children is not supported by several recent studies. Secondly, children as young as ten, who do not have capacity for informed consent, are starting a treatment course that will likely render them infertile or sterile and this raises complex bioethical issues (Baron & Dierckxsens, 2021).
Other adverse effects of GAT are based on a more uncertain evidence base. I provide a brief outline of some of the areas of concern. Cross-sex hormones are associated with cardiovascular health risks, such as thromboembolic, coronary artery, and cerebrovascular diseases (Hembree et al., 2017; Irwig, 2018). Cross-sex hormones may also increase the risk of certain cancers (Hembree et al., 2017; Mueller & Gooren, 2008). Puberty blockers may have negative impact on bone mineral density, which may not be fully reversible, with an associated risk of osteoporosis and fractures (Biggs, 2021; Hembree et al., 2017). Recently, findings from animal studies have increased concerns that puberty blockers may negatively and irreversibly impact brain development due to critical time-windows of brain development. In one study on rams, long-term spatial memory deficits induced by use of puberty blockers in the peripubertal period were found to persist into adulthood (Hough et al., 2017). For those young patients who undertake surgery, there are also the risks of surgical complications (Akhavan et al., 2021). One understudied outcome of mastectomies, for those who later want to and can become pregnant, is the grief about inability to breast feed.
Puberty blockers, cross-sex hormones and genital surgery also pose risks to sexual function, particularly the physiological capacity for arousal and orgasm. It is important to be aware there is a dearth of research studying the impact of GAT on GD youth’s sexual function, but I provide a brief discussion of this important topic. Estrogen use in transwomen is associated with decreased sexual desire and erectile dysfunction and testosterone for transmen may lead to vaginal atrophy and dyspareunia (Hembree et al., 2017). It seems widely assumed that testosterone simply improves transmen’s sexual functioning. However, placebo-controlled studies from the non-transgender population indicate the situation is likely more complex. For example, studies indicate that testosterone may impact female sexual desire in a bell-shape curve manner, and at high levels may have no benefit or even have negative impact on sexual function (Krapf & Simon, 2017; Reed et al., 2016). Also of note, in medical conditions that are associated with high testosterone levels, such as polycystic ovarian syndrome, impaired sexual function (e.g., arousal, lubrication, sexual satisfaction, and orgasm) has been reported (Pastoor et al., 2018).
Recently, surgeon and WPATH president-elect, Marci Bowers, raised concern that puberty blockers given at the earliest stages of puberty to birth sex males, followed by cross-sex hormones and then surgery, might adversely impact orgasm capacity because of the lack of genital tissue development (Ley, 2021). One study has reported that some young adults, who had received puberty blockers, cross-sex hormones and laparoscopic intestinal vaginoplasty, self-reported orgasmic capacity (Bouman et al., 2016). However, this finding does not negate Bower’s concerns, as it did not make any assessment of the correlation between Tanner stage at initiation of puberty blockers with orgasm outcome. Of note, some of the patients in the study were over the age of 18 at start of GAT. Further, its findings do not apply to those undergoing penile skin inversion vaginoplasty. Importantly, Bouman et al. found that 32% of their participants self-reported being sexually inactive and only 52% reported having had neovaginal penetrative sex more than once. A recent literature review on sexual outcomes in adults post-vaginoplasty noted the paucity of high-quality evidence but reported that “up to 29% of patients may be diagnosed with a sexual dysfunction due to associated distress with a sexual function disturbance” (Schardein & Nikolavsky, 2022). Another recent systematic review of vaginoplasty reported an overall 24% post-surgery rate of inability to achieve orgasm (Bustos et al., 2021).
Coleman et al. (2022) claimed that “longitudinal data exists to demonstrate improvement in romantic and sexual satisfaction for adolescents receiving puberty suppression, hormone treatment and surgery.” However, the supporting citation requires scrutiny. Bungener et al. (2020) was a cross-sectional study of 113 young adults, 66% of whom were transmen (most who had undergone mastectomy and gonadectomy, not genital surgery). For its claims of post-surgery increases in sexual experience, it relied on recall of pre-surgical experiences. This means it is at high risk of recall bias, especially given surgery was undertaken up to 5 years (mean 1.5 years) prior to assessment. Further, it focused on sexual experiences, which might naturally be expected to increase as adolescents enter young adulthood, and there was no evaluation of sexual function domains, such as arousal, orgasm, or pain. The study did report current sexual satisfaction but failed to compare this to pre-surgical functioning (or to the Dutch peer comparison group). Thus, it is unable to demonstrate whether sexual satisfaction improved following GAT. On the three questions about sexual satisfaction (frequency, how good sex feels, and sex life in general), 59 to 73% were reportedly moderately to very satisfied. This would appear to mean that 27 to 41% were not satisfied, which is a sizeable minority. Importantly, these sexual satisfaction questions had an approximately 45% missing data rate—an issue not discussed by the authors. This means the authors’ conclusion that the majority was satisfied with their sex life is at high risk of bias. Of additional note, at the post-surgical assessment time these young transgender adults were significantly less sexually experienced than their Dutch peers. Thus, in sum, this study provides little reassurance about the sexual function outcomes of GAT in GD youth.
Lastly, in terms of risks, there are increasing reports of discontinuation of hormone treatments, regret and detransition in young people who have received GAT (Boyd et al., 2022; Hall et al., 2021; Littman, 2021; Vandenbussche, 2022). Two recent studies have relied on pharmaceutical prescription records, both using 2018 as the end date of data collection (Roberts et al., 2022; van der Loos et al., 2022). Their reported rates of discontinuation varied widely. For the US cohort, Roberts et al. (2022) reported, for those who had started CSH treatment before age 18, a 4-year CSH discontinuation rate of 25%. For the Dutch cohort, van der Loos et al. (2022) reported on CSH discontinuation rates in adolescents, evaluated according to the “meticulous” Dutch protocol, who had commenced puberty blockers before age 18. People “assigned female at birth” had a CSH discontinuation rate of 1% at a median of 2.3-years follow-up, and those “assigned male at birth” had a 4% discontinuation rate at median 3.5-years follow-up. Previous research from this Dutch group has indicated that average time to detransition was over 10 years (Wiepjes et al., 2018). Thus, given the van der Loos et al. (2022) study’s short median follow-up time and young follow-up age (median 19.2 for people “assigned female at birth” and 20.2 for “assigned male at birth”), it seems likely that these discontinuation rates will increase over time. It is also concerning to note that 75% of the Dutch youth who discontinued CSH had undergone gonadectomies, but at follow-up they were receiving neither CSH nor sex hormones consistent with their birth sex.
Ongoing Research
Currently, several large long-term observational studies are underway which involve collecting and analyzing data on patients receiving routine GAT at CAGCs (Olson-Kennedy et al., 2019; Tollit et al., 2019). The aims of these studies are to provide the urgently needed rigorous empirical data to bolster the weak evidence base that currently underpins the GAT approach. However, as discussed above, it is critical to note that this type of observational research is prone to bias, confounding, and lacks ability to distinguish treatment effects from placebo effects (Fanaroff et al., 2020; Pocock & Elbourne, 2000). Thus, it is unlikely to provide the rigorous empirical data that can convincingly demonstrate a causal relationship between treatment and outcome.
Further, there seems to be a problematic tension between the research and clinical agendas of CAGCs. GAT is being provided in a clinical environment that maximizes the placebo effect. This is the same environment in which the same clinicians are researching GAT’s efficacy. As previously discussed, while a placebo effect-enhancing environment may be appropriate for a clinical environment, it is far from an ideal treatment efficacy research environment, particularly when DBRCTs are not possible and RCTs are not undertaken. In the next section, I delve more deeply into exploring this issue. First, however, I will take a brief detour with an example that illustrates the risks when expert opinion and low-quality evidence are relied on as a basis for medical interventions.
A Recent Example from Medical History of the Dangers of Medical Advice Based on Weak Evidence: The Iatrogenic Tragedy of Prone Infant Sleep Position and Sudden Infant Death Syndrome
Gender medicine clinicians and researchers have consistently stated that RCTs would be unethical (de Vries et al., 2011; Smith et al., 2001; Tollit et al., 2019). However, as Valenstein (1986) discussed in his study of the history of lobotomy, the ethics of implementing new treatments without a rigorous evidence base also need to be considered. The harm that can be done by well-intentioned, but erroneous medical advice based on prestigious physicians’ clinical judgment without an adequate evidence base can be illustrated by infant sleep position and sudden infant death syndrome (SIDS). Prior to the middle of the twentieth century, it was common practice for mothers to place infants on their backs to sleep (Högberg & Bergström, 2000). The influential pediatrician, Benjamin Spock, was an early advocate of the prone position (front sleeping) for infants. He recommended it in his popular book, Baby and Childcare, from the 1956 edition through until 1985 (Gilbert et al., 2005). This recommendation, that became widespread, was mainly based on clinical wisdom that such a position reduced risk of death from aspiration of vomit and had additional benefits such as decreased crying and reduced head flattening. Early research appeared to support this clinical advice. However, by the 1980s, more rigorous research demonstrated that the prone position increased risk of SIDS. Then medical advice gradually changed to strongly recommending infant supine (back) sleeping. A marked drop in SIDS rates followed. Several biases (e.g., the healthy adopter bias and observer bias) are thought to have contributed to the erroneous clinical belief that prone sleeping position was the safest position. It has been estimated that between the 1950s and the 1990s the infant prone sleeping advice, recommended by well-meaning clinicians and prestigious medical organizations, may have contributed to the deaths of tens of thousands of infants (Gilbert et al., 2005; Sperhake et al., 2018).
Gender-Affirming Treatment for Youth with Gender Dysphoria: A Perfect Storm for Placebo Effect
The reader may ask: Why focus on GAT for GD youth? Is GAT any different from other contemporary medical treatments that also are not underpinned by rigorous evidence? I would reply—indeed, this is an issue in other areas of medicine. For example, the response rate in the placebo groups in antidepressant medication clinical trials is known to be high (Benedetti, 2021a). However, in contrast to GAT, we know this because there have been many RCTs comparing antidepressants to placebos. A recent review, that included placebo in the network meta-analysis, found that all the antidepressants under review were more efficacious than placebo in adults with major depressive disorder (Cipriani et al., 2018). This finding has been challenged by some who argue that the benefits of antidepressants beyond placebo effect seem to be minimal (Jakobsen et al., 2020). However, one of the key points to make is that placebo effect in antidepressant medication response is at least known about and discussed by many researchers, clinicians, and their patients (personal clinical experience), rather than not considered at all, as seems to be the situation to date for GAT for GD youth. Gender medicine clinicians and researchers might take note of a recent meta-analysis of antidepressants in pediatric populations, which recommended that the influence of placebo response needs to be considered in pediatric clinical trial design and implementation (Feeney et al., 2022). Furthermore, it seems particularly vital to consider the potential role of placebo effect in GAT outcomes because the stakes are high. Medical and surgical GAT, being given to vulnerable minors, lead to life-long medicalization and hold the risk of serious irreversible adverse impacts, such as sterility and impaired sexual function. Thus, we need strong evidence that they are as efficacious for critical mental health outcomes as claimed and that there are no less harmful alternatives.
In the field of GD youth medicine, there is a combination of features that seems to create a perfect storm setting for placebo effect. Thus, we have a population of vulnerable youth presenting with a condition, which has no objective diagnostic tests, and that is currently undergoing an unexplained rapid increase in prevalence and marked change in patient demographics. The treatment response is mainly based on patient-reported outcomes (yes, this can be the case for other conditions but remember we are considering the combination of features, not just a feature in isolation). Some clinicians, who may be affiliated with prestigious institutions, enthusiastically promote GAT, including on the media, social media, and alongside celebrity patients. Some make overstated claims about the strength of evidence and the certainty of benefits of GAT, including an emphasis on their “life-saving” qualities, and under-acknowledge the risks. Alternative psychosocial treatment approaches are sometimes denigrated as harmful and unethical conversion practices or as “doing nothing.” This combination of features increases the likelihood that there will be a complex interplay of heightened placebo and nocebo effects in this area of medicine, with significant implications for research and clinical practice. Some examples of these types of issues are now provided.
Overstatement of the Certainty of Benefits and Under-Acknowledgment of Risks
Some professional organizations and leading GAT clinicians, in publicly available communications to GD youth, the public, and policy makers, appear to overstate the certainty of GAT’s benefits and provide inadequate discussions of risks (Clayton, 2022a; Cohen, 2021a, b; Olson-Kennedy, 2015, 2019; Telfer, 2019, 2021). For example, GATs have been described in such communications as “absolutely life-saving” (Olson-Kennedy, 2015) and being underpinned by “robust scientific research” (Telfer, 2019). It is notable that these same clinicians in their peer reviewed publications acknowledge the sparse empirical evidence with critical knowledge gaps (Olson-Kennedy et al., 2019), and the urgent need for more evidence for this relatively new treatment approach (Tollit et al., 2019). Thus, there seems to be a kind of Janus-faced narrative, with a placebo effect-enhancing face of overstated certainty/strong evidence of benefit displayed to GD youth, their families, and policy makers, and the more realistic face of uncertainty/lack of evidence turned toward peer reviewers and the research community. Of note, several publications in the peer review literature that have made overstated claims about GAT have recently required correction (Bränström & Pachankis, 2020; Pang et al., 2021; Zwickl et al., 2021).
The Dangers of an Exaggerated Suicide Narrative
A specific issue that is important to discuss is the repeated claims that GD youth are at high suicide risk and that GAT reduces this risk. Parents report being told by clinicians that their child will suicide if a trans identity is not affirmed (Jude, 2021). Clinicians’ public statements also indicate this message is being given, or at least implied, to parents and young people (Cohen, 2021b; Marchiano, 2017). A recent editorial in The Lancet stated puberty blockers reduce suicidality and to remove access to them was to “deny” life (The Lancet, 2021). However, there is no robust empirical evidence that puberty blockers reduce suicidality or suicide rates (Biggs, 2020; Clayton et al., 2021). The authors of the paper, that was the basis for The Lancet’s claim, subsequently clarified that they were not making any causal claims that puberty blockers decreased suicidality (Rew et al., 2021). Another paper, claiming to have found that barriers to gender-affirming care was associated with suicidality, had to withdraw this claim in a significant correction to their article (Zwickl et al., 2021).
Furthermore, the suicidality of GD youth presenting at CAGCs, while markedly higher than non-referred samples, has been reported to be relatively similar to that of youth referred to generic child and adolescent mental health services (Carmichael, 2017; de Graaf et al., 2022; Levine et al., 2022). A recent study reported that 13.4% of one large gender clinic’s referrals were assessed as high suicide risk (Dahlgren Allen et al., 2021). This is much less than conveyed by the often cited 50% suicide attempt figure for trans youth (Tollit et al., 2019). A recent analysis found that, although higher than population rates, transgender youth suicide (at England’s CAGS) was still rare, at an estimated 0.03% (Biggs, 2022).
Of course, any elevated suicidality and suicide risk is of concern, and any at risk adolescent should be carefully assessed and managed by expert mental health professionals. However, an excessive focus on an exaggerated suicide risk narrative by clinicians and the media may create a damaging nocebo effect (e.g., a “self-fulfilling prophecy” effect) whereby suicidality in these vulnerable youths may be further exacerbated (Biggs, 2022; Carmichael, 2017). This type of risk has been discussed in other similar situations involving youth (Abrutyn et al., 2020; Canetto et al., 2021; Shain & AAP COMMITTEE ON ADOLESCENCE, 2016).
An Excessively Negative Portrayal of the Previous Standard and Current Alternative Treatment Options
Clinicians and groups advocating for GAT tend toward framing any non-affirming treatment approaches as harmful, ineffective, and unethical, and sometimes equate psychotherapeutic approaches with conversion practices (Ashley, 2022). However, others argue that there are a range of contemporary therapeutic approaches which are not “affirmative,” but neither are they conversion practices (D’Angelo et al., 2021). Such approaches can include: Careful assessment and diagnostic formulation, appropriate treatment of co-existing psychological conditions, supportive and educative individual/family psychological care, group therapy, developmentally informed gender exploratory psychotherapy, trauma-informed psychotherapy, and a non-promotion of early childhood social transition (sometimes labeled under the umbrella term of “watchful-waiting,” which should not be interpreted as “doing nothing”) (D’Angelo et al., 2021; de Vries & Cohen-Kettenis, 2012; Hakeem, 2012; Kozlowska et al., 2021; Lemma, 2021).
It is important to note that psychotherapeutic approaches for this group of patients are also based on limited evidence. More research into their efficacy is required. One critical consideration here seems to be that ethical psychological approaches do not hold the same adverse risk profiles as do the hormonal and surgical treatments (Baron & Dierckxsens, 2021).
Recently, two Scandinavian youth gender services have drawn similar conclusions and instigated a more cautious approach to hormonal treatments for GD minors, placing a higher emphasis on psychological care (Kaltiala-Heino, 2022; Socialstyrelsen, 2022). Furthermore, in England, the Cass Review into the country’s youth gender services has released its interim report (Cass, 2022). In response, the National Health Service’s “Interim Service Specification” for GD youth specialist services has specified that the primary intervention for youth will be psychosocial support and psychological interventions. A cautious approach to social transition is recommended and puberty blockers will only be available in the context of a formal research protocol (National Health Service, 2022).
Given all this, it is hard to accept the claims that GAT is prima facie the best treatment model for today’s cohort of GD youth. Furthermore, the unwarranted negative portrayal of contemporary psychotherapeutic approaches likely creates nocebo effects and undermines the possibility of providing such ethical care to GD youth (Kozlowska et al., 2021).
Clinicians’ Media and Social Media Promotion of Gender Affirmative Treatment
There is intense media and social media coverage of “trans youth” issues. Some surgeons are promoting their gender-affirming surgeries on social media platforms that are popular with young adolescents (Ault, 2022). Some clinicians encourage the celebratory media coverage of GAT, stating it may empower young trans people to seek GAT (Pang et al., 2020). They largely dismiss concerns that the identified association between positive media stories and increased referral rates to CAGCs may be indicative of a social contagion phenomenon. This is despite the reports of the sudden emergence of gender dysphoria, especially in adolescence, and its association with social influence (Kaltiala-Heino, 2022; Littman, 2018, 2021; Marchiano, 2017). Gender clinicians also condemn and have attempted to prevent what they consider as excessively negative media coverage of GAT (although others judge it as reasonable and balanced) (Australian Press Council, 2021; Pang et al., 2022). These clinicians are likely correct that critical media coverage of GAT could negatively impact referrals to gender clinics and might upset some patients. However, a deliberate strategy of promoting an unbalanced celebratory GAT narrative through the media and social media could contribute to social contagion and placebo effects.
What is the right balance? The Australian Press Council’s judgment on a clinician’s complaints about what she considered as excessively negative press coverage may, arguably, provide an example of some balance on these matters. Of note, while some of the complaints were upheld, many were not and it was judged that “even medical treatment accepted as appropriate by a specialist part of the medical profession is open to examination and criticism…needs to be debated…and was sufficiently justified in the public interest” (Australian Press Council, 2021).
The Exclusive Promotion of Gender-Affirming Treatments within Child and Adolescent Gender Clinics
There is indication of an unbalanced promotion of a celebratory GAT narrative occurring within CAGCs, where, simultaneously, there is a deep enmeshment of the clinical, advocacy, and research agendas. This has already partly been discussed in the sections above, but one detailed example is provided. The Trans20 study is a prospective cohort study based on children and adolescents seen at Melbourne’s Royal Children’s Hospital Gender Clinic (RCHGC) which provides a GAT model of care (Telfer et al., 2018; Tollit et al., 2019). It is important to highlight that this study’s human research ethics committee (HREC) approval was not for the treatment approach, which was implemented as routine clinical care, rather it was for matters such as collection and storage of data, and longitudinal follow-up of discharged patients.
In 2019, an amended HREC approval was granted, allowing a “newsletter blog” to be sent to patients and families with the aim of improving patient engagement with the study. This change was described as raising no new ethical issues. This “first ever” newsletter asked for help with the Trans20 survey completion (Royal Children’s Hospital, 2019). This research request was placed amid positive accounts of the service and its patients. For example, following attendance at the clinic’s single session assessment triage (SSNac) young people were described as feeling ��empowered…and more likely to start living as their preferred gender,” and having improvements in mental health and quality of life. A colorful diagram showed the increased rates of social transition that followed SSNac attendance, and the section concluded “Hopefully the improvements after SSNac are a taste of things to come!” One pro-GAT parent/carer support network, that also fundraises for the RCHGC, was spotlighted. There was a “lived experience” piece in which a well-known transitioned, now young adult, patient was pictured receiving an award. This patient provided a personal testimony of the clinic’s medical director: She “will always be one of my biggest heroes…an incredible person: Intelligent, compassionate and strong.”
This newsletter’s communication raises much to think about. The point I want to make here is that sandwiching the requests for a research survey completion between celebratory accounts of the clinic seems likely to magnify the impact of bias and placebo effect on research outcome findings. For example, consider the likely impact on patient bias (patients wanting to please the clinician by giving positive reports), response bias (patients with positive experiences of the clinic more likely to complete the surveys), social learning/contagion, prestige suggestion, and the Hawthorne phenomenon. Furthermore, consider this newsletter as part of the whole therapeutic ritual, enhancing the psychological and neurobiological placebo mechanisms. Apart from this research impact, we can also wonder whether such a newsletter is ideal clinical practice. In my opinion, there are problems. Think, for example, of the young GD patient who may be hesitant to transition. Where is the celebration of this young person’s choices? Communications from the clinic, such as this newsletter, may contribute to feelings that, unless he/she transitions, he/she lacks courage (having not been “empowered”) and that he/she will never be an award-winning celebrated patient. This may act as a covert form of pressure on patients to transition or, for those who do not, act as a nocebo effect negatively impacting their psychological outcomes.
Where to From Here?
There are no easy solutions to the complex research and clinical issues presented in this Letter. Here, I present a few ideas to stimulate discussion. The first step would seem to be more professional awareness and debate. Independent reviews by expert clinicians and methodologists, not currently involved in clinical practice and research in this area (thus, having some emotional distance and minimizing intellectual conflict risk), could helpfully advise further research and clinical strategies. England’s Cass Review is an example of this type of approach (Cass, 2022).
Clinicians should also make measured and honest statements to patients, families, policy makers, and the public about the evidence for GAT’s benefits. Placebo effects could also be noted in the limitations section of any research papers. In addition, in public discourse, the media and clinicians could present not only celebratory transition stories, but also: Realistic positive stories of those with gender dysphoria who have decided not to transition or have delayed transition until maturity; accounts of patients who have benefitted from ethical psychological approaches; and accounts of those who have had negative transition experiences. Detransition, regret, and harm from transition should be acknowledged and publicized as a significant risk. A recent paper detailing the elements of a comprehensive informed consent process is timely and important (Levine et al., 2022). However, while a comprehensive informed consent process is vital, it does not address the issue of how the whole ethos of a clinic and the media/social media milieu may act to influence young patients and their families and undermine the capacity for true informed consent.
Conclusion
In conclusion, this Letter has noted that although GAT for GD youth lacks a rigorous evidence base, it is undertaken as routine medical treatment in a strongly placebo effect enhancing environment. It is within this environment that research into its effectiveness is being undertaken. One consideration raised by this relates to clinical practice: When does such a strongly placebo effect enhancing environment meet optimal clinical practice standards? When, if at all, does it veer into the territory of unethical practice that involves deception and undue influence? This Letter has also highlighted that such a placebo effect enhancing environment presents grave problems for research (particularly non-DBRCT research). It seems unlikely that the current research being undertaken in this field will be able to untangle benefits that are due to the placebo effect from those due to the interventions’ specific effectiveness. Thus, especially given the adverse risk profile of the hormonal and surgical interventions, it may be that yet again well-intentioned physicians are engaging in medical practices that cause more harm than benefit (Clayton, 2022b). The research and clinical conundrums presented in this Letter have no easy answers. However, as a first step, there is an urgent need for more awareness of the placebo effect and for rigorous and thoughtful debate over how best to proceed in research and clinical practice in this area of medicine.

Spatial Topography of the Brain
A meta-analysis of magnetic resonance imaging data of neuronal activity in advanced meditation practitioners has discovered a reorganization of information processing topography in which brain regions involved in present-awareness have increased activity while ego-centric and subject-object (discriminatory) neuronal information processing layers are mitigated [1]. The researchers identify the neural correlates associated with the feeling of unity of experience—a state that advanced meditation practitioners can experience, often described as a non-dual state of experience that does not maintain the strong distinction between self-other or subject-object information, but rather a unified experience of oneness, or singularity.
Figure 1: Interoceptive Information and Its Integration with Emotional, Cognitive, and Motivational Signals from an Array of Cortical and Subcortical Regions. Interoceptive information of constantly changing body states arrives in the posterior insula by ascending sensory inputs from dedicated spinal and brainstem pathways via specific thalamic relays. This information is projected rostrally onto the anterior insula, where it is integrated with emotional, cognitive, and motivational signals from an array of cortical and subcortical regions. As a result, the anterior insula supports unique subjective feeling states. The anterior insula regulates the introduction of subjective feelings into cognitive and motivational processes by virtue of its cortical location at the cross-roads of numerous pathways involved in higher cognition and motivation. Abbreviations: AI, anterior insula; AMG, amygdala; dACC, dorsal anterior cingulate cortex; DLPFC, dorsolateral prefrontal cortex; PI, posterior insula; THAL, thalamus; VMPFC, ventromedial prefrontal cortex; VS, ventral striatum. Image and image description from [3].
"From the meta-analysis data, the researchers determined that there is a distinctive shift in these information processing layers such that DMN activity is reduced, DMN-CEN synchronization undergoes a more positive connectivity, and dominant information processing shifts to the attention networks of higher order brain regions like the prefrontal cortex: leading to greater present-moment awareness and integration of self with environment and internal feelings."
Such reorganization of the brain’s information processing topology is significant in changing how a person perceives the world and their relationship to the experiences of daily life, in a therapeutic context this has made meditation a popular practice (even medically prescribed) to lower anxiety and stress, as mindfulness strengthens the brain’s ability to stay focused in the present-moment, so that undue worry is not given from constantly contemplating the past and potential future events. The former of which there is no way to change, and the latter of which is most effectively managed by actions in the present moment. Such mindfulness techniques have a long history of extolling benefits, with philosophical traditions from Stoicism to Buddhism explaining how mindfulness, focus in the present moment, and relinquishing negative judgements about events—that arise from excessive self-referential cognitive processing—can reduce suffering and help people achieve the most effective and optimal version of themselves [4].
The main results of the study are: (i) decreased posterior default mode network (DMN) activity
(ii) increased central executive network (CEN) activity
(iii) decreased connectivity within posterior DMN as well as between posterior and anterior DMN
(iv) increased connectivity within the anterior DMN and CEN
(v) and significantly impacted connectivity between the DMN and CEN (likely a nonlinear phenomenon).
Highlights:
This study has shown a significant and objective change in brain function because of meditation, inverting the predominant levels of information processing so that experience is not executing on “auto-pilot” but instead heightened awareness in the present moment enables highly conscious and effective activity. We would further posit that there are biophysical changes occurring all the way to the cellular and molecular resolution of information processing and bioenergetics. Such that the highly focused attention of meditation can engender a state of singularity, not just a singularity of perception. It is possible that such a state mitigates the decohering interactions in the molecular dynamics of the cell, so that long-range quantum coherent states are bolstered, leading to greater degrees of qubit information processing and Bose-Einstein like states (via mechanisms like Frohlich condensation [5]). Increases in information processing at this atomic resolution couples the body much more strongly to the vacuum information structure, enabling accession of nonlocal information and energy. Such that these coherent states correlate with an expanded state of awareness, in which non-local information processing in the macromolecular networks of the cellular system give much greater integration of signals from the self, environment, and beyond, enabling experiences of non-duality, or connection with the greater universe (beyond our normal mundane quotidian experiences of the world).

BPD is a neurobiological illness—a finding that would drastically alter how the disorder should be conceptualized and managed.
MRI studies have revealed the following abnormalities in BPD: • hypoplasia of the hippocampus, caudate, and dorsolateral prefrontal cortex • variations in the CA1 region of the hippocampus and subiculum • smaller-than-normal orbitofrontal cortex (by 24%, compared with healthy controls) and the mid-temporal and left cingulate gyrii (by 26%) • larger-than-normal volume of the right inferior parietal cortex and the right parahippocampal gyrus • loss of gray matter in the frontal, temporal, and parietal cortices • an enlarged third cerebral ventricle • in women, reduced size of the medial temporal lobe and amygdala • in men, a decreased concentration of gray matter in the anterior cingulate • reversal of normal right-greater-than-left asymmetry of the orbitofrontal cortex gray matter, reflecting loss of gray matter on the right side • a lower concentration of gray matter in the rostral/subgenual anterior cingulate cortex • a smaller frontal lobe.
MRS studies reveal: • compared with controls, a higher glutamate level in the anterior cingulate cortex • reduced levels of N-acetyl aspartate (NAA; found in neurons) and creatinine in the left amygdala • a reduction (on average, 19%) in the NAA concentration in the dorsolateral prefrontal cortex.
From fMRI studies, there is evidence in BPD of: • greater activation of the amygdala and prolonged return to baseline • increased functional connectivity in the left frontopolar cortex and left insula • decreased connectivity in the left cuneus and left inferior parietal and the right middle temporal lobes • marked frontal hypometabolism • hypermetabolism in the motor cortex, medial and anterior cingulate, and occipital and temporal poles • lower connectivity between the amygdala during a neutral stimulus • higher connectivity between the amygdala during fear stimulus • deactivation of the opioid system in the left nucleus accumbens, hypothalamus, and hippocampus • hyperactivation of the left medial prefrontal cortex during social exclusion • more mistakes made in differentiating an emotional and a neutral facial expression.
DTI white-matter integrity studies of BPD show: • a bilateral decrease in fractional anisotropy (FA) in frontal, uncinated, and occipitalfrontal fasciculi • a decrease in FA in the genu and rostrum of the corpus callosum • a decrease in inter-hemispheric connectivity between right and left anterior cigulate cortices.
Studies have found evidence of hypermethylation in BPD, which can exert epigenetic effects. Childhood abuse might, therefore, disrupt certain neuroplasticity genes, culminating in morphological, neurochemical, metabolic, and white-matter aberrations—leading to pathological behavioral patterns identified as BPD.
There is substantial scientific evidence that BPD is highly heritable— there also is evidence of gene-environment (G.E) interactions (ie, how nature and nurture influence each other).
----
Dialectical behavioral therapy (DBT) was found to attenuate amygdala hyperactivity at baseline, which correlated with changes in a measure of emotion regulation and increased use of emotion regulation strategies.
Of the serotonin receptor genes, polymorphisms in 5HTR2A and 5HTR2C have been most closely correlated with BPD. Variants of the 5HT2A receptor are known to correlate with suicide, affective lability, and impulse control. 5HTR2A polymorphisms correlate with borderline traits.
Moreover, subjects who were homozygous for the HTR2C rs6318 G/G genotype had a higher frequency of the TPH2 “risk” haplotype. Taken together, the data suggest that a TPH2 “risk” haplotype may change serotonin in a way that predisposes to BPD. Patients may be more susceptible to a specific variant of 5HTR2C, which may further contribute to the pathogenesis of BPD.
Carriers of the (oxytocin receptor gene on chromosome 3p25.3) OXTR rs53576 A allele are more likely to perceive others negatively, experience loneliness, and endorse subjective symptoms of psychological stress with correspondingly high cortisol and other stress-related biomarkers. Prosocial behaviors, such as empathy, confidence, and positivity, decrease.
Three studies support the use of oxytocin in the treatment of BPD. Simeon and colleagues16 concluded that oxytocin moderately decreased stress reactivity. Oxytocin decreased threat hypersensitivity, measured via eye fixation and amygdala activity, in response to angry faces. Brüne and colleagues also found reduced attention and avoidant reactions to angry faces in subjects with BPD after oxytocin administration. Their data suggest that oxytocin administration may interfere with trust in patients with BPD, especially in those who have been exposed to trauma.

Why Women Have Higher Rates of PTSD Than Men Sexual trauma is particularly toxic to mental health.
The topic of women and sexual trauma has certainly been in the news lately, provoking a great deal of emotion and outrage. Much trauma research focuses on male combat veterans, yet women actually have double the rate of Post-Traumatic Stress Disorder (PTSD) as men! While combat veterans have high rates of PTSD and suicide and deserve our attention, so do women sexual assault and abuse survivors. This article will review the symptoms of PTSD, its prevalence in women and men and factors that may contribute to sex differences in PTSD risk, including the types of traumas that women experience, differences in brain processing, coping, and societal reactions.
What are the symptoms of post-traumatic stress disorder?
To be diagnosed with PTSD, a survivor needs to have the following symptoms present for at least 1 month and severe enough to interfere with day to day functioning:
Re-experiencing symptoms. These involve reacting as if the trauma is still present, including having nightmares, flashbacks, or frightening thoughts (1 needed)
Avoidance symptoms. These are attempts to avoid being reminded of the trauma, such as staying away from people, places, or things that are similar to aspects of the trauma, or avoiding and shutting out thoughts and feelings related to the trauma (1 needed)
Arousal and reactivity symptoms. These are signs of excess anxiety or anger and physiological arousal, including having angry outbursts, feeling “on edge,” being hyper-vigilant for threat, or having difficulty sleeping (2 needed)
Cognition and mood symptoms. These are negative thoughts, feelings, or judgments relating to the event or memory impairments and include feeling excessive guilt, blaming yourself unreasonably, having difficulty remembering aspects of the event, seeing yourself or the world negatively, or not finding interest or pleasure in regular activities (2 needed).
It is normal to experience some of these symptoms right after an event like a rape or a serious car accident, but if symptoms last for more than a month then you may have PTSD and should seek mental health evaluation and treatment. Sometimes PTSD symptoms can be triggered months or years after the actual event.
What are the rates of PTSD in women and men?
The lifetime prevalence of PTSD is 5-6% in men and 10-12% in women. This means that women have almost double the rate of PTSD as men. Women’s PTSD also tends to last longer (4 years versus 1 year on average). Women are more at risk for chronic PTSD than men. What factors could account for this difference?
Do women experience more traumas than men?
One suggestion for the higher rate of PTSD is that women experience more traumatic events than men. In fact research shows the opposite is true. Women report about a third less traumas than men. This means women are at higher risk of PTSD even though they experience fewer traumatic life events than men on average. This is surprising and suggests there may be something about the type of trauma or women's reactivity that puts them at higher risk.
Do types of trauma differ between women and men?
Research shows that men and women do indeed experience different traumas.
Men are more likely to experience:
combat trauma
accidents
natural disasters
disasters caused by humans.
Women experience more incidents of:
sexual abuse
domestic violence
sexual assault
Sexual traumas are prevalent and particularly toxic to mental health! Sexual abuse typically begins at a young age, when the brain is still growing, leading to a lasting impact on emotion regulation and fear response. About one out of every 6 women has experienced attempted or completed sexual assault or rape in her lifetime. Victims of sexual trauma are more likely to be diagnosed with PTSD than victims of nonsexual trauma. While you might be able to stay away from combat, there is a psychological and relationship cost to staying away from sexual activity or being a reluctant participant (in the context of a committed relationship).
The #metoo movement has highlighted the fact that women in many different career settings experience high rates of ongoing sexual harassment by bosses and colleagues. These experiences of exploitation, besides acting as chronic stressors, may trigger emotions associated with past trauma in women who have been raped and abused. Similarly, events in the news, especially those involving unfair treatment or sexual exploitation of women can trigger strong reactions in the many women who have experienced sexual abuse or assault.
What makes sexual trauma so traumatic?
When I see survivors of sexual trauma in my practice, they often exhibit high levels of fear and vigilance, shame, and self-blame. Sexual traumas carry a stigma and make women feel ashamed even when there is no valid reason to feel this way. Lawyers representing perpetrators often attack the victim's character, lifestyle, and reputation in attempts to get their clients acquitted. Many women who have been traumatized turn to alcohol or drugs to block out feelings associated with the trauma and thereby make themselves vulnerable to further sexual exploitation or coercion. They may report body hatred or dissatisfaction or exhibit eating disorders. Many victims of sexual trauma have trust issues, which can get in the way of healthy relationships as an adult. Some may isolate themselves or become avoidant of romantic relationships.
Women abused as children or teens report feeling too scared or ashamed to tell an adult. Some are not believed or told to “get over it.’ It is difficult to describe the level of violation and loss of sense of a healthy self that sexual abuse and sexual assault can cause to women and men. This is compounded when our society responds with dismissal, minimization, or disbelief.
What other factors might account for the different rates of PTSD?
Women are more susceptible than men to other types of mental health issues like anxiety disorders or depression. These may be the result of sexual assault or abuse, but can also be caused by other factors like genetic vulnerability to depression or high anxious temperament. However, societal attitudes, gender roles, and income inequalities also affect mental health and mood. Women earn less than men for the same jobs. Many women work in jobs or live in households where they have less power and control over their lives than men. This is especially the case in traditional cultures. Professor Norris and her colleagues studied gender differences in PTSD across cultures and found that the increased risk of PTSD symptoms in women was magnified in more traditional cultures.
Do men and women have different brain responses to trauma?
Although more research needs to be done, it is possible that women’s brains react differently to fear-arousing or threatening stimuli than men’s brains. In experimental studies, women showed more activation of the right amygdala, right rostral anterior cingulate cortex (ACC) and dorsal ACC than men when they were exposed to fearful stimuli. The right side of the brain is associated with emotionality in general and negative emotions in particular. These same brain areas are involved in the stress response and also in mind-body awareness and emotional reactivity. Another study using physiological measures showed that women acquired fear more easily than men when exposed to fearful stimuli.
Do men and women cope with stress differently?
Men and women may cope differently with stress. There is some evidence that women are more likely than men to exhibit a “tend and befriend” response to stress. They may react to stress by crying for help, turning to others for social support, or care-taking. Men show more angry and avoidant or problem-solving responses when they are stressed. Because women’s responses are more linked to their social network and availability of support, they may be more vulnerable to PTSD symptoms when they feel lonely or rejected or when social support is not available.
Women tend to show more of an emotional and ruminative response to stress, whereas men are more likely to engage in problem-solving. Ruminating about your stressors can make their impact worse if it stops you from taking action, or if the situation is not controllable. In general, women seem to report stronger emotional reactions to major life events (like death or divorce). Women are also more affected by stressors impacting people close to them, like their parents, friends, partners or children. These coping factors may contribute to women’s higher rate of PTSD, but more research needs to be done. Women who have been raped or sexually assaulted are also likely to blame themselves more and see themselves more negatively, which can exacerbate their reactions to the trauma.
Summary
Research shows that women have higher rates of PTSD than men despite a lower rate of trauma experience. Women’s greater exposure to sexual trauma, sexual coercion, and intimate partner violence plays a role, as well as biological, environmental, and coping factors. When families, social groups, government bodies, news media, or organizations disbelieve, disrespect, or minimize girls' and women's experiences of sexual trauma, this can cause a great deal of harm to mental health.

The authors undertook a PET study to examine changes in regional brain activity (reflected in regional cerebral blood flow) during states of low blood glucose (hypoglycemia). Hypoglycemia evoked sympathetic and parasympathetic autonomic arousal, apparent in a range of physiological and neuroendocrine measures. States of hypoglycemia and autonomic arousal were associated with enhanced activity in rostral anterior cingulate (ACC), orbitofrontal cortex, thalamus, and brainstem. One interpretation is that these activity increases reflect generation and control of autonomic responses to the low-level physiological challenge of hypoglycemia

Diffusion Weighted Magnetic Resonance Imaging Revealed Changes in the Somatosensory and Motor Cortex of a Mild Relapsing-Remitting Experimental Autoimmune Encephalitis Mouse Model: OAJBS Publishers
Diffusion Weighted Magnetic Resonance Imaging Revealed Changes in the Somatosensory and Motor Cortex of a Mild Relapsing-Remitting Experimental Autoimmune Encephalitis Mouse Model by Nyoman D Kurniawan* in Open Access Journal of Biomedical Science (OAJBS)
Multiple sclerosis (MS) is debilitating disease affecting the central nervous system (CNS). MS pathology has been primarily associated with demyelination and neuroinflammation in the CNS white matter (WM) structures. Recently, clinical studies using high-field magnetic resonance imaging (MRI) have reported diffuse pathological changes observed in the grey matter (GM) regions. This study aims to investigate neurological changes underpinning disease development in mild experimental autoimmune encephalitis (EAE) mouse model of relapsing remitting MS using magnetic resonance diffusion-weighted imaging (DWI). Relapsing-remitting EAE disease was induced in C57BL/6 mice using myelin oligodendrocyte protein (MOG35-55) emulsified in saponin (Quil-A) adjuvant and pertussis toxin. The animal clinical scores were monitored throughout the disease and prior to fixation at acute and chronic relapsing stages. Ex-vivo brain samples were imaged using conventional MRI and DWI at 16.4 Tesla. MRI relaxation and diffusion tensor imaging (DTI) parameters were evaluated to assess structural changes and the results were correlated with Black Gold II myelin staining. Acute EAE mice showed increases in mean and radial diffusivities within WM structures the corpus callosum, external capsule and hippocampal commissure. Chronic EAE mice showed extensive reductions in fractional anisotropy in vital GM structures such as the motor cortex, somatosensory area, and rostral hippocampal regions, as well as in part of the WM anterior cingulate and external capsule. DTI findings were confirmed by a notable reduction in myelin staining and correlated with adverse clinical scores in chronic animals. This study presented for the first time the use of ex-vivo ultra-high-field MRI to detect mild EAE pathology in GM somatosensory and motor cortex using DTI MRI, providing invaluable insight into neuropathological evolution during the relapsing-remitting disease. https://biomedscis.com/fulltext/diffusion-weighted-magnetic-resonance-imaging-revealed-changes-in-the-somatosensory-and-motor-cortex.ID.000263.php

[ID: On the left there is a picture of a mockup article displayed in CatCo's website. In the top center there is an image of the Luthor Corp building in National City, before Lena rebranded it L-Corp. Atop the image in the left corner there is a red rectangle with white inside spelling 'News' in all caps. Below the image there is another red rectangle with the word News inside it, but this time it's a lighter red and the letters are red. Beside the rectangle in all caps it says, National City in black letters. Below that the title of the article says in all caps: Luthor Corp moving to National City. Below the title it says: By Snapper Carr Oct. 3rd 2016. Below that the body of the article says: Following the arrest of Lex Luthor a few days ago, who was sentenced to 37 consecutive life sentences, Luthor Corp lost its CEO. In his place Lena Luthor, Mr. Luthor's adopted sister, became the new CEO of Luthor Corp. In a press conference Ms. Luthor announced that she's moving the company's base of operations to National City.
This being the home of our resident hero, Supergirl. Was it chosen on purpose? It will remain to be seen if Lena Luthor decides to continue her family's legacy or break expectations and lead her company to a brighter future.
On the right there is a picture of a mockup article displayed in CatCo's website. The same details as before repeat themselves. Only things that change are:
Image displaying a screenshot of season 1 episode 20 where you can see National City citizens walking through the streets at night while being mind controlled.
Title of the article: What was Myriad?
By Cat Grant May 25th, 2016
Body of the article: Yesterday National City was attacked. The whole city was mind controlled with a device called Myriad. This device is of alien origin, as Supergirl informs us. It was made with the intention to be used only as a last resource in case of a global crisis. It was made with the intention to save a planet. This planet was Krypton. The culprit of yesterday's attack was a group of rogue kryptonians, their mission to save Earth from humans' self-destructive tendencies.
Myriad works by shutting down the connection between the amygdala and the rostral anterior cingulate cortex. The parts of the human brain that give rise to optimism and hope. Here I quote a citizen about their experience under Myriad: "Under Myriad, I could see, I could hear, but it was like I was a complete stranger to myself." Supergirl's speech saved us all by giving back what we needed the most. Hope. End ID]
Okay so, I got bored yesterday and decided to do a mockup of Kara's article exposing Lex Luthor in season 4.
Some friends in Discord told me to share in Tumblr so here we are lol.
(You have my permission to use it, but please credit me ♡. Oh and tag me in whatever you use it! I would love to see it.)

Some Background on That One Super Famous Cluster B Personality Disorder and Some Brief Meta Tying It to Kai Parker’s Problematic (but Fine AF) Ass Because I Said I Would Do This
Okay, this isn’t a research paper, so I’m not going to put ref points throughout the post, but I’ll write down the full names of the texts and articles I used at the bottom in case you’re interested in checking them out yourself. Some info/pics come from old annotated notes, but I likely will only use those for examples provided by previous professors. NONE of these visuals are mine, they’re copyrighted and I’m posting them for educational purposes. I’m making no profit off of this. Obviously. This is a damn fan blog.
First off, lets talk behavior and psychopathology, then I’ll get into like...the barest bit of some of the complex anatomy and physiology behind them. Then I’ll talk Kai Parker a little and how he fits this. This post is gonna be hellaciously long, since it’s an academic reference/meta, so read more under the cut:
Personality is something pervasive, long term, and generally not mutable in a person. And individual’s personality will develop in childhood and are measured by rating the general patterns of disordered conduct/socializing of traits known as the big 5: neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness. These traits, like anything dealing with the mind, are measured on a spectrum and patterns of extremely high pervasiveness of traits in some areas and extremely low pervasiveness in others that results in a diminished or troubled quality of life is what results in a personality disorder.
Personality disorders are sorted into 3 groups called clusters:
Kai falls into cluster B - he has antisocial personality disorder (ASPD from here on, can also be noted as APD), historically called “sociopathy”. ASPD is more commonly diagnosed in men than in women, (although this might be in part due to societal/gender biases of both the patient and the clinician, but I digress), with a prevalence in the clinical population of 3.9-5.9% and in the general population of 1.0%-1.8%. It’s rare, but not the rarest personality disorder by any means. No unicorns here.
I personally denote ASPDers as the biggest con-artist assholes you’ll ever have the displeasure of meeting, but that’s not very academic, so I’ll copy my one of my textbook’s format and break this up into a few categories. More information can be found in references.
Clinical Description And Criteria:
“I am entitled to break rules.”
That right there is the sun with which ASPD revolves around. The disorder is characterized by extreme selfishness and disregard for others, highly impulsive and risky behavior (like drug use, reckless stunts, fighting), and unusual emotional responses and fits of rage, but no deficits in reasoning ability. People with ASPD know what they’re doing, understand the social norms/ rules behind them and don’t care. In regards to the Big 5 personality traits this is what they look like (L is low, H is high):
And diagnostic criteria for ASPD on the DSM-5 looks like this:
YOU HAVE TO HAVE DISPLAYED CONDUCT DISORDER AS A CHILD TO BE DIAGNOSED WITH ASPD AFTER 18. Remember an individual’s personality develops in childhood and is long-lasting. Conduct disorder in children is diagnosed with this criteria:
ASPD has a pretty high heritabilty (about 40-50%) and it’s fostered in hostile environments characterized by lack of warmth, exposure to violence, high negativity, parental inconsistency or parental ASPD, and/or poverty.
While ASPD is associated with poor impulse control, there is still no deficit in reasoning ability. ASPDers with a high intelligence quotient (IQ) are less likely to get caught or engage in illegal or destructive behavior because they know the game. They’d rather be free to fuck people over than in a system and can be quite adept at hiding their traits. This leads me to psychopathy. There’s still some debate about whether psychopathy should be considered different from ASPD, but most clinicians these days agree that psychopathy as a subset of symptoms that fall under ASPD. So just like all squares are rectangles, but not all rectangles are squares, all psychopaths (at this point) are ASPDers, but not all ASPDers are psychopaths.
Psychopathy:
Defining characteristics of psychopathy include:
If you’re having a hard time reading this, the red and blue branches indicate what aspects of psychopathy are influenced by what bit of anatomy dysregulation. AMG - amygdala, PCC - posterior cingulate cortex, MPFC - medial prefrontal cortex. The coronal slices (red, bottom blue) are as if you’re looking at a person face to face - your left is their right. Top blue is scanned from the right side (See that scrunchy round thing behind the straight part? Below the “PCC”? That’s the cerebellum behind the brain stem. It’s in the back of your head, to help with orientation.) Middle blue is as if you and the person are facing the same direction, but you’re taller and looking straight down on their head. Hope that helps you out!
In general, with regards to criminal behavior, high IQ psychopaths are called “subclinical” psychopaths and are not generally studied bc...well, they blend in. They find other, legal or discreet ways to fulfill thrill seeking behavior.
Psychopathy has some actual distinct differences in the brain that can be physiologically measured. It’s typically shown by differences in the the right amygdala and the anterior rostral prefrontal cortex (arPFC from here on), especially on the right side. (The right hemisphere of the brain is responsible for emotional recognition and expression, while the amygdala controls fear responses/recognition and the PFC in general controls different aspects of higher cognition. In this case, it’s likely the conversion of emotionality to morality, since emotions play a large part in fostering sympathy and from there moral judgement.) See?
Integrative Biopsychosocial Model of APD:
Bio (Genetics and neurobiology): Twin and adoption studies show that ASPD is highly heritable, but it’s the gene-environment interaction that is integral for ASPD development. ASPD is an endophenotype - the underlying aspects of disorder are genetic (low levels serotonin and dopamine (the chemical neurotransmitters), or in the case of psychopaths, low levels of serotonergic or dopaminergic axons (the anatomy that receives the NT)) and provide the unique emotional aspects of ASPD, but the social behavior presentation is guided by the environment (early childhood stress, lack of social guidance, etc). The arousal theory, if you’re interested, is based of the endophenotypes and can explain how certain behaviors arise from them (i.e. ASPDers, esp. psychopaths, are stimulation seeking bc of low response in reward systems (serotonergic/dopaminergic)). *I add on dopamine bc it’s an important chemical in the brain’s reward system, but serotonin is the key one.
Psychosocial (mental and environmental): Inconsistent parental punishments, lack of punishment for aggressive/antagonist behavior, environments that propagate violence, high risk-reward and fearless psychology all lend themselves to the development of the disorder.
The disorder is like a measuring cup and each influence is water filling it until the water level reaches the mark where the disorder presents itself.
When it comes to ASPD, prevention, not treatment is preferred. Redirecting behavior patterns in kids with conduct disorder is your best bet compared to trying to get a fully formed, highly aggressive ASPD adult to behave.
Here’s a case study from my abnormal psych textbook depicting what the you’d most likely see in clinical ASPD case (i.e. in “the system” , like prison or a hospital):
(See why I said con-artists asshole? Ryan’s a fucking dick.)

Okay, so now that we got the science, on to Kai Parker:
Right, so I think it’s safe to say that, canonically, Kai mostly fits the criteria for ASPD, but you’re def free to go back over all that up there and do your own comparison. We all know how Kai is an admitted “sociopath”. Considering Joshua Parker’s behavior, we can probably take a gander on the genetic component and considering the entire Gemini premise, plus the way Kai in particular was raised as the outsider in his family, we have an idea of the hostile and warmth-lacking environment that fostered it.
Because it’s TVD, I do think Kai was written to cater that whole “handsome, suburban white boy gone wrong” schtick, but I also think he’s one of the most subtly well-fleshed characters that show ever produced. There’s this one article I read for a neuro lit course (“Loneliness and associated violent antisocial behavior: analysis of the case reports of Jeffrey Dahmer and Dennis Nilsen.” authored by W.H. Martens and G.B. Palmero) that really stuck to me in a pervasive way and it’s about how chronically festering feelings of neglect and loneliness, of feeling like an unaccepted outsider, drove Dahmer and Nilsen to take their victim’s lives in a misguided way to dissuade the loneliness.
Having read that makes me wonder how Kai, the fictional serial killer, reflects his real life counterparts. The drive for merging and becoming coven leader is something that would force others to acknowledge him, which ties into his “black sheep” speech, his “I was never hugged as a child and my siblings were kept away” complaint (There are a lot of inconsistencies in his dialogued back story that bother me, but it makes me wonder if he ever lied about his past: “my favorite memory is when I finally beat him to death” and the preceding story about Mario Kart with the bby bro seems like something he might have just made up to fuck with Elena), and other vocalizations he’s made about his past which point to him being the misfit and desiring a sense of belonging. While we know Kai’s ASPD is a part of his characterization, this to me seems out of the norm for this disorder, simply because it indicates an understanding of sympathy that is unwittingly emotional.
Of course, Kai could also just want to be able to lord the world’s biggest “FU!” over his abusers.
Either way, anti or not, when using the ASPD/sociopath argument to defend or dismantle Kai as a character, I think it’s a good idea to keep in mind that Kai was written inconsistently. He shows very little impulsivity or recklessness in 1994, one trait which is almost a given with ASPD, nor was he flightly/irresponsible. He always had some end-goal or plan in mind. This was pre-merge. But he was also manipulative and showed no regret about the people he hurt. Obviously, each case of the disorder is unique because they exist on a spectrum, but the pattern and criteria are there due to broad commonalities in each case. The way the media tends to portray ASPD is not all consistent with the way the disorder presents irl.

Could simple tests predict which OCD treatment will work?
New research could improve the odds that people with obsessive-compulsive disorder will receive a therapy that really works for them.
A working treatment eludes more than a third of people with OCD who currently get treatment.
The study suggests the possibility of predicting which of two types of therapy will help teens and adults with OCD: One that exposes them to the specific subject of their obsessive thoughts and compulsive behaviors, or one that focuses on general stress reduction and a problem solving approach.
While the researchers caution that it’s too early for their work to be used by patients and mental health therapists, they’re planning and conducting further studies that will test the framework and see if it also applies to children with OCD or obsessive tendencies.
Two therapies for OCD
The new study examines advanced brain scans of 87 teens and adults with moderate to severe OCD who were randomly assigned 12 weeks of one of the two types of therapy.
The researchers found that in general, both types of therapy reduced the symptoms that participants experienced.
The approach known as “exposure therapy,” a form of cognitive behavioral therapy, or CBT, was more effective and reduced symptoms more as time went on, compared with stress-management therapy, also known as SMT.
But when the researchers looked back at the brain scans taken before the patients began therapy, and linked them to individual treatment response, they found striking patterns.
The researchers took the brain scans while patients performed a simple cognitive task and responded to a small monetary reward if they did the task correctly.
Those who started out with more activation in brain circuits for processing cognitive demands and reward during the tests were more likely to respond to CBT—but those who started out with less activation in those same areas during the same tests were more likely to respond well to SMT.
“We found that the more OCD-specific form of therapy, the one based on exposure to the focus of obsession and compulsion, was better for relieving symptoms, which in itself is a valuable finding from this head-to-head randomized comparison of two treatment options,” says senior author Stephan Taylor, a professor of psychiatry at Michigan Medicine, the University of Michigans’s academic medical center. “But when we looked at the brain to see what was behind that response, we found that the more strength patients had in certain brain areas were linked to a greater chance of responding to exposure-based CBT.”
Brain scans
The brain regions and circuits that had the strongest links to treatment have already been identified as important to OCD—and have even been targets for treatment with an emerging therapy called transcranial magnetic stimulation.
Specifically, stronger activity in the circuit called the cinguloopercular network during the cognitive task, and stronger activity in the orbitostriato-thalamic network when the reward was at stake, was associated with better response to exposure-based CBT. But lower activity in both regions was associated with better response to the stress-reduction SMT. The effects didn’t vary across age groups.
“These findings speak to a mechanism for therapy’s effects, because the brain regions associated with those effects overlap substantially with those implicated previously in this disorder,” says Luke Norman, who led the work as a neuroscience postdoctoral fellow and is now a scientist at the National Institutes of Health.
“This suggests we need to draw upon the most-affected networks during therapy itself, but further research is needed to confirm.”
The researchers scanned participants’ brains while they underwent a test that required them to correctly pick the correct letter out of a display, and offered a potential monetary reward if they performed the task correctly. This measured both their ability to exert control over their cognitive processes in picking out the right letter, and the extent to which the promise of a reward motivated them.
One of the areas most linked to CBT treatment response was the rostral anterior cingulate cortex (rACC). Past research has already linked it to OCD and treatment response in general, and it’s thought to play a key role in self-regulation of response to OCD triggers.
Previously, the researchers had shown that in general, people with OCD tend to have reduced activation in the rACC when asked to perform tasks that involve cognitive control.
Among those who responded best to CBT, the researchers saw stronger pre-treatment activation in areas of the brain associated with learning how to extinguish fear-based responses to something that has caused fear in the past. Because exposure therapy for OCD involves facing the thing or situation that provokes obsessive and fearful responses, having a stronger ability to be motivated by rewards might help someone stick with therapy despite having to face their triggers.
Personalizing treatment
The findings suggest a path to personalizing the choice of therapy not by doing brain scans on everyone with OCD—which would be impractical—but by using everyday tests that measure the kinds of characteristics that might predict better success with one therapy or the other.
Easily administered behavioral tests could be developed to help therapists recommend CBT to those who have the most cognitive control and reward responsiveness, and SMT to those who would benefit most from being taught to relax and use problem-solving techniques to improve their response to stressors, says co-senior author Kate Fitzgerald, a pediatric OCD specialist at Michigan Medicine who leads multiple studies of OCD therapy for children and adolescents.
But computer-based brain-training exercises that can strengthen these tendencies, and rewards for exposing oneself to the thing or action that triggers OCD symptoms, may hold the potential to improve therapy response, she says.
“This kind of research may help inform efforts to do cognitive control training and ramp up the circuits that help patients overcome conflict between obsessive fears and insight that these fears don’t make sense so that patients can dismiss the fear as improbable, rather than trying to make it go away with compulsive behaviors,” she says.
“Our research shows that different brains respond to different treatments, and if we can build on this knowledge we could move toward a more precision-medicine approach for OCD.”
In children and teens, whose brains are still maturing, there’s an especially good chance of helping them improve their brains’ control functions.
Call for trial participants
Fitzgerald and her team are currently recruiting young people with diagnosed OCD, and OCD-like tendencies, for a clinical trial that provides CBT and includes brain scanning before and after therapy.
Since OCD symptoms typically start in the tween years, though diagnosis may not occur until the teen or young adult years, it’s important to study children with sub-clinical symptoms, she notes.
Though the study involves in-person interactions for the brain scans, the CBT exposure therapy is done through video chat. In fact, Fitzgerald says, this can make it easier for children and teens to confront the item or situation that triggers their OCD-like impulses, because these are often found in the home environment.
“We need families and patients to engage with researchers in studies like these,” says Fitzgerald. “Only through research can we understand what works best for different groups of patients. And perhaps by doing so we can expand the availability of the most evidence-based OCD therapies—including by engaging psychologists and clinical social workers in leading treatment programs, in addition to psychiatrists at specialized centers.”
The National Institute of Mental Health funded the study.
The study’s ClinicalTrials.gov identifier is NCT02437773.

Why obeying orders can make us do terrible things
War atrocities are sometimes committed by ‘normal’ people obeying orders. Researchers from the Netherlands Institute for Neuroscience measured brain activity while participants inflicted pain and found that obeying orders reduced empathy and guilt related brain activity for the inflicted pain. This may explain why people are able to commit immoral acts under coercion.
Many examples in the history of mankind have shown that when people obey orders from an authority, they are able to perform atrocious acts towards others. All the genocides that mankind has known, generally referred to as crimes of obedience, have shown that having a part of the population complying with orders to exterminate other human beings led to the loss of countless lives, cultures and civilizations. “We wanted to understand why obeying orders impacts moral behavior so much. Why people’s willingness to perform moral transgressions is altered in coerced situations”, says Dr Emilie Caspar, co-first author of the present study.
FEELING THE PAIN
When humans witness another person experiencing pain, be it emotional or physical, they have an empathic reaction, and this is thought to be what makes us averse to harming others. “We can measure that empathy in the brain, because we see that regions normally involved in feeling our own pain, including the anterior insula and the rostral cingulate cortex, become active when we witness the pain of others, and the stronger that activity, the more empathy we experience, and the more we do to prevent harm to others”, explains Dr Valeria Gazzola, co-senior author of the paper. This process is deeply ingrained in our biology and shared by other mammals, such as rodents or apes. “We evaluated in this study if obeying orders to inflict pain to someone else would reduce the empathic response compared to freely deciding to inflict – or not to inflict – the same pain”, reports prof. Christian Keysers, the other co-senior author of the present study.
In the study published in NeuroImage, the authors used pairs of participants, with one being assigned the role of ‘agent’ and the other the role of ‘victim’. Agents were placed in an MRI scanner to record their brain activity during the task. They were told that they had two buttons; one triggering the administration of a real, mildly painful, shock on the victim’s hand in exchange for +0.05€, and another triggering no shock and no money. Over the course of 60 rounds, agents were either free to choose to administer – or not – this shock to the victim, or they received orders from the experimenter to inflict – or not – the same shock. This task was designed to involve a difficult moral decision for agents: increasing one’s own monetary gain by causing pain to another person or not.
REDUCED ACTIVATIONS
The authors observed that agents sent more shocks to victims when they were coercively instructed than when they freely decided. “Neuroimaging results showed that empathy-related regions were less active when obeying orders compared to acting freely. We also observed that obeying orders reduced activations in brain regions associated with the feeling of guilt”, explains Kalliopi Ioumpa, co-first author of the present study.
The observation that obeying an order to inflict pain reduced activation in empathy and guilt related brain regions explains, at least partly, why people can commit highly immoral acts towards others under coercion. These results have huge implications in terms of understanding the power that obedience has over human behavior and offer new insights into the possibility of preventing mass-atrocities committed because of a lack of empathy for victims. “The next step will be to understand why so few people resist immoral orders. Is it because their empathy weakens when they are following orders? A better understanding of how the brain processes empathy and instructions may lead to ways to help us resist calls to commit violence in the future”, says Dr Emilie Caspar.

Inhibitory control is a component of executive function that governs the suppression of interference from irrelevant stimuli. Individuals diagnosed with many neuropsychiatric disorders, including many neurodevelopmental disorders such as ADHD (attention deficit hyperactivity disorder) and OCD (obsessive compulsive disorder), share neural dysfunction of inhibitory control.1
Although individuals diagnosed with OCD or ADHD share impairments in inhibitory control, they present with disorder-specific functional and structural brain abnormalities in frontostriatal region, according to new findings of a meta-analysis performed by investigators affiliated with King's College London and Karolinska Institute in Stockholm, Sweden. The findings were published in JAMA Psychiatry.2
Patients with OCD show reduced GMV (z = 1.622, P < .001) and function (z = 2.133, P < .001) in rostral and dorsal anterior cingulate/medial prefrontal cortex. Patients with ADHD, on contrary, show reduced function predominantly in the right ventrolateral prefrontal cortex (z = 1.229, P < .001).
