title: A 16-year-old with episodic hemisdystonia.
abstract: The paroxysmal dyskinesias are a subset of the hyperkinetic movement disorders characterized by their episodic nature. Classification based on precipitating factors is helpful in considering treatment and prognosis. The clinical similarities with partial seizures are discussed. An approach to differential diagnosis, diagnostic evaluation, and treatment options are presented.
