Paroxysmal dyskinesia with interictal myoclonus and dystonia: a report of two cases.
Idiopathic paroxysmal dyskinesias (PxD) are characterized by attacks of hyperkinetic movement, with no inter-ictal symptoms. We report two cases, one with paroxysmal kinesigenic dyskinesia and another with paroxysmal exercise-induced dystonia, both of whom had myoclonus and dystonia between attacks. This previously unreported association highlights the heterogeneity of paroxysmal movement disorders.
