Paroxysmal Kinesigenic Dyskinesia

Paucar, Martin; Malmgren, Helena; Svenningsson, Per

Background: Paroxysmal kinesigenic dyskinesia (PKD) is a rare condition associated with heterozygous mutations in the PRRT2 gene.

Phenomenology shown: In this letter we illustrate the phenomenology of PKD in a man previously misdiagnosed as Tourette’s syndrome.

Educational value: Regardless of underlying phenotype, PKD is highly responsive to some antiepileptic drugs.
