title: Downward vertical gaze palsy as a prominent manifestation of episodic ataxia type 2: a case report.
abstract: Episodic ataxia type 2 (EA2) is an inherited autosomal dominant disorder characterized by intermittent ataxia, nausea, vomiting, dysarthria, or nystagmus. We report a case of EA2, which downward gaze palsy exists as a common sign in all her attacks. Responsiveness of EA2 to acetazolamide was observed in this patient.
