A Case of Symptomatic Paroxysmal Kinesigenic Choreoathetosis in Basal Ganglia Lesions

ABSTRACT

Paroxysmal choreoathetosis (dyskinesia) is classified into two subtypes paroxysmal kinesigenic choreoathetosis(PKC) and dystonic choreoathetosis(PDC). PKC is also classified into two subgroups (idiopathic & symptomatic). PKC is characterized by choreoathetotic, dystonic and/or tonic movements induced by sudden voluntary movements, without loss of consciousness, urinary incontinence and clonic movement. Symptomatic PKC is associated with neurological disease such as cerebral palsy, multiple sclerosis, hypocalcemia, birth asphyxia, head injury and lesions of basal ganglia and premotor cortex. We report I case of symptomatic PKC, who showed characteristic symptoms of PKC and bilateral lesions of basal ganglia.
