Athetosis is a commonly occurring symptom in the disease cerebral palsy. [14] Of all people with the disease, between 16% [15] and 25% [4] of them actually exhibit the symptom of athetosis. A component of this is the finding that most often the symptoms that involve athetosis occur as a part of choreoathetosis as opposed to athetosis alone. [16]
Choreoathetosis is the occurrence of involuntary movements in a combination of chorea (irregular migrating contractions) and athetosis (twisting and writhing).. It is caused by many different diseases and agents.
[6] [7] A video of dystonia in a patient with dyskinetic cerebral palsy can be seen here: on YouTube. [7] Choreoathetosis (CA) is characterized by hyperkinesia (chorea i.e. rapid involuntary, jerky, often fragmented movements) and hypokinesia (athetosis i.e. slower, constantly changing, writhing or contorting movements).
Speech and language disorders, known as dysarthria, are common in athetoid CP patients. [5] In addition, ADCP patients may have trouble eating. [3] Hearing loss is a common co-occurring condition, [2] and visual disabilities can be associated with Athetoid Cerebral Palsy. Squinting and uncontrollable eye movements may be initial signs and ...
A movement disorder similar to PKD was first mentioned in research literature in 1940 by Mount and Reback. They described a disorder consisting of attacks of involuntary movements but unlike PKD, the attacks lasted minutes to hours and were found to be caused by alcohol or caffeine intake. [15] They named it paroxysmal dystonic choreoathetosis.
Chorea, or (rarely) choreia, (/ k ə ˈ r i ə /) is an abnormal involuntary movement disorder, characterized by quick movements of the hands or feet. It is one of a group of neurological disorders called dyskinesias. The term chorea is derived from Ancient Greek χορεία 'dance', as the movements of the body is comparable to dancing.
Levodopa-induced dyskinesia (LID) is a form of dyskinesia associated with levodopa (l-DOPA), used to treat Parkinson's disease.It often involves hyperkinetic movements, including chorea, dystonia, and athetosis.
Paroxysmal nonkinesigenic dyskinesia (PNKD) is an episodic movement disorder first described by Mount and Reback in 1940 under the name "Familial paroxysmal choreoathetosis". [2] It is a rare hereditary disease that affects various muscular and nervous systems in the body, passing to roughly fifty percent of the offspring.
