Hey there, do you have some cool sources on other types on involuntary movement that are not tics?

Yes, I do! Here is a list of involuntary movements, a simple description, and links to resources on them:

Akathisia -> an inability to remain still

StatPearls article

cleveland clinic article (very good)

Akinesia -> the loss of spontaneous, voluntary muscle movement

StatPearls article (free article)

healthline article

Athetosis -> slow, continuous, involuntary writhing movements commonly affecting arms and hands

healthline article

Chorea -> rapid, chaotic movements that seem to flow from one body part to another

NINDS article

StatPearls article

Dystonia -> sustained or repetitious muscular contractions; often produces abnormal posture

mayo clinic article

NINDS article

StatPearls article

Hemiballismus -> sudden, intermittent, flinging, or ballistic high amplitude movements commonly affecting proximal limb muscles

StatPearls article

Myoclonus → sudden, brief, involuntary muscle twitches

mayo clinic article

NINDS article

StatPearls article

Parkinsonism -> a clinical syndrome characterized by slowness, rigidity, tremor, and postural instability

StatPearls article

parkinson's disease vs parkinsonism

types of parkinsonism (parkinson's UK)

types of parkinsonism (parkinson's foundation)

Stereotypies -> repetitive, rhythmic movements with typical onset in early childhood

stereotypies in adults

medlink article

Tardive Dyskinesia -> uncontrollable and repetitive movements of the tongue, lips, face, trunk, and extremities

webmd article

Tics -> sudden, rapid, recurrent, and nonrhythmic movements or vocalizations

mayo clinic article on tourette syndrome

NINDS article on tourette syndrome

child mind institute article on tics and tourette

Tremor -> rhythmic back-and-forth or oscillating involuntary movements

NINDS article

classification of tremor

(at request I can find Tumblr or blog posts talking about personal experiences with some of these movements)

Basic definitions come from this article: https://www.psychiatrist.com/pcc/effects/drug-induced-abnormal-involuntary-movements-prevalence-and-treatment/

Hemiballism - type of chorea caused in most cases by a decrease in activity of the subthalamic nucleus of the basal ganglia 📝💡

....Comparing to chorea, movements are more extensive

The Longze brand popcorn machine has a large production output and a high ball removal rate. The bladder is a Japanese Beihai inner bladder. The bladder is of good quality and durable, and is heated evenly. Scraping and stirring will not stick to the pot. One pot can produce 10 catties of popcorn, and one pot in 4-5 minutes. It is a large domestic production equipment for ball shape popcorn machines. The working principle of popcorn machine: The popcorn machine equipment is mainly composed of a pot body, a frame body, a stirring system, a heating system, a speed-regulating transmission device, a stirring shaft, and a pot body turning system. It adopts a hemiball shape stainless steel pot body formed by one-step stamping. Using liquefied gas, natural gas, steam, electromagnetic and other heating methods, the stirring method adopts a special inclined transmission, the planetary agitator used is fully in contact with the pot body, and the non-integer transmission ratio of transmission revolution and rotation is realized, so that there is no stirring in the pot Dead ends. Use advanced transmission and sealing structure to make the transmission part and the pot clean and hygienic. Using frequency conversion speed control power, the operation is more stable. It adopts hydraulic lifting, turning the pot and transporting materials, and avoids disassembly and assembly of the agitator, which saves manpower and reduces labor intensity. It is an excellent food processing equipment. Fully automatic large-scale commercial ball shape popcorn machine is a multi-functional and efficient equipment that integrates mixing, dispersion and mixing.

Movement Disorders CVA

Movement disorders occur uncommonly after stroke and include both hyperkinetic and parkinsonian conditions. They can occur at the time of stroke or appear as a later manifestation. Stroke lesions are typically due to small vessel cerebrovascular disease in the middle or posterior cerebral artery territory, vessels supplying the basal ganglia. Hemorrhagic lesions are more likely to induce hyperkinetic movements. Movement disorders in the setting of stroke tend to resolve spontaneously over time. Medical and surgical therapies are available to treat the movement problems.

Movement disorders occur uncommonly in association with stroke in adults and tend to resolve over time. A study of 2,500 first stroke patients found that 1% developed an acute or delayed movement disorder.1 In most cases, the lesions were due to small vessel cerebrovascular disease in the middle or posterior cerebral artery territories. This is not surprising since the blood supply to the basal ganglia, the site of pathology for most movement disorders following stroke, emanates from branches of these vessels.

Hemorrhagic strokes appear to be more likely to lead to movement disorders than ischemic ones.2Ninety percent of the acute-onset movement disorders resolved within 6 months.1 Despite the low frequency and tendency to resolve, the recognition of a movement disorder in the setting of stroke can be important in localizing the lesions and in suggesting an underlying etiology. They may need to be a target for therapy, and can importantly contribute to disability and long-term outcome. This review summarizes current knowledge regarding movement disorders following stroke.

1. Hemiballism/hemichorea is the most common movement disorder reported to occur after stroke, present in 40% of cases in a case series.1 Hemiballism is characterized by vigorous, irregular, poorly patterned, high-amplitude movements of the limbs on one side of the body and is often viewed as a severe type of chorea.3 Chorea consists of brief, arrhythmic, non-repetitive movements that appear to move from one muscle to the next and is typically worsened by volitional movements. After stroke, over time as it improves, ballism often evolves into the lower amplitude chorea. Besides hemiballism, ballism can involve one limb (monoballism) or all limbs (biballism or paraballism). In one study of 25 patients with ballism, 19 had hemiballism.4 The majority of patients with hemiballism have both choreic and ballistic movement.5Other commonly associated dyskinesias include orobuccal, oromandibular, lingual, and dystonic movements.4,5 It has been reported that 72% of cases of hemiballism are caused by stroke, with an average age at onset for stroke-induced hemiballism of 66 years.4

2. Dystonia consists of involuntary sustained muscle contractions causing twisting and repetitive movements or abnormal postures. After hemiballism-hemichorea, dystonia is the second most common movement disorder after stroke, representing about 20% of cases,1 and often taking the form of focal or hemidystonia.

Hemiballismus Definition, Symptoms, Causes, Treatment

Learn all about hemiballismus. It is a relatively rare hyperkinetic movement disorder characterized by involuntary, violent, coarse and wide-amplitude movements involving ipsilateral arm and leg. Although classically related to lesions in the subthalamic nucleus, in clinical-radiological series of hemiballism most patients had lesions outside this nucleus, involving mainly other basal ganglia…
