Paroxysmal kinesigenic dyskinesia, abbreviated PKD and also called paroxysmal kinesigenic choreoathetosis, is a rare hyperkinetic movement disorder belonging to the paroxysmal dyskinesias. It is characterized by attacks of involuntary movements that are triggered by sudden voluntary movements. According to the source lead, the number of attacks can increase during puberty and decrease in a person's twenties to thirties. The involuntary movements can take several forms, such as ballism, chorea or dystonia, and they usually affect only one side of the body or one limb in particular.
