Abstract:
Paroxysmal choreoathetosis(dyskinesia) is classified into two subtypes: paroxysmal kinesigenic choreoathetosis(PKC) and paroxysmal dystonic choreoathetosis(PDC). PDC consist of attacks of dystonia and /or choreoathetosis during which the patients are dysarthric or anarthric, have irregular clonic movement and dystonic posturing of extremities, and these not precipitated by sudden movement but rather by alocohol, coffee and stress. Attacks are longer (2ninute-4hours), but less frequently(3-4times/day) than PKC, they are not responsive to anticonvulsants(eg, phenytoin, carbamazepine) but controlled by clonazepam.This disease is rare, in the reported families, the transmission was clearly autosomal dominant with high penetrance.
