Transient dysarthria and hemiparesis in an adolescent

Paroxysmal kinesigenic dyskinesia is a rare disorder characterised by brief, recurrent episodes of involuntary movements triggered by sudden voluntary motion.Atypical symptoms such as dysarthria and hemiparesis in paroxysmal kinesigenic dyskinesia may mimic transient ischaemic attacks or structural brain lesions.Anticonvulsants such as carbamazepine are highly effective in treating paroxysmal kinesigenic dyskinesia and can significantly reduce episode frequency and improve quality of life when initiated early.
