[Paroxysmal dyskinesis and epilepsy]

Based on the available literature, we outline the classification criteria of paroxysmal involuntary movements with instant onset and termination. Four types of those movements are currently distinguished: dystonic Mount-Reback paroxysmal choreoathetosis, kinesigenic paroxysmal choreoathetosis, exercise-induced paroxysmal dystonia, and hypnogenic paroxysmal dystonia. We present the clinical characteristics of those entities, as well as diagnostic and therapeutic aspects. An association with epilepsy is emphasised, which seems to predominantly apply to hypnogenic dystonia and kinesigenic paroxysmal choreoathetosis.
