Paroxysmal choreoathetosis

Familial paroxysmal nonkinesigenic dyskinesia (referred to as familial PNKD in this entry) is characterized by unilateral or bilateral involuntary movements; attacks are spontaneous or precipitated by alcohol, coffee or tea, excitement, stress, fatigue, or chocolate. Attacks involve dystonic posturing with choreic and ballistic movements, may be accompanied by a preceding aura, occur while the individual is awake, and are not associated with seizures. Attacks last minutes to hours and rarely occur more than once per day. Attack frequency, duration, severity, and combinations of symptoms vary within and among families. Age of onset is typically in childhood or early teens, but can be as late as age 50 years. [from GeneReviews]
