Abstract

Background: Episodic ataxia type 2 (EA2) is a rare disorder characterized by paroxysmal gait instability, dysarthria, and dizziness. It is caused by CACNA1A mutations. Spinocerebellar ataxia type 6 (SCA6) rarely causes episodic ataxia-like symptoms. Acetazolamide has limited effectiveness for treating episodic ataxia.

Methods: We investigated the effect of drug therapy in two patients with EA2 and one patient with SCA6 who presented with episodic ataxia. All three cases were CACNA1A-associated diseases.

Results: In these three cases, acetazolamide administration was partially and transiently effective for episodic ataxia attacks. After levetiracetam addition, the number of ataxic attacks was significantly reduced, although the durations of attacks were not changed. The effect of levetiracetam was stable and continued for seven years. Levetiracetam and acetazolamide reduced chronic cerebellar ataxia in an SCA6 patient.

Conclusions: In this small number of cases, levetiracetam was considered effective in two patients with EA2 and mildly effective in one patient with SCA6.
