  • Title: [Paroxysmal choreoathetosis].
    Author: Fegers S.
    Journal: Fortschr Neurol Psychiatr; 1991 Jun; 59(6):234-8. PubMed ID: 1885121.
    Abstract:
    Paroxysmal Choreoathetosis (PC) is a rare disorder which is characterized by spells of involuntary movements of the limbs, the head and the trunk lasting from a minute to several hours. PC is classified in two main types. In Paroxysmal Dystonic Choreoathetosis (PDC) the attacks are prolonged and precipitated by alcohol, emotion or fatigue, in Paroxysmal Kinesigenic Choreoathetosis (PKC) the attacks last less than 5 minutes and are precipitated by sudden movements. Although the pathophysiology of the disorder ist still uncertain, it is supposed to be an extrapyramidal disorder. Clinical features, therapeutical and differential diagnostic aspects are discussed. There is a certain risk that the disorder is misinterpreted as psychogenic or hysterical in nature. The mostly good response to medication can help the patients avoid superimposed emotional problems.
