Vigabatrin (gamma-vinyl GABA; GVG), an irreversible inhibitor of GABA-transaminase, at a daily dose of 2-4 g, and a placebo were each administered orally for 4 months to 14 patients with cerebellar ataxia (9 with Friedreich's ataxia, 5 with olivopontocerebellar atrophy), in a double-blind, placebo-controlled crossover study. For the group as a whole, there was no significant difference between the GVG and placebo periods in any of the parameters of cerebellar symptomatology measured. Individually, one patient showed some improvement after 3 months of treatment with 2 g/day GVG. Tolerance to 4 g/day GVG was poor, whereas 2 g/day was well tolerated. The results suggest that agents which increase central GABA concentrations are not likely to be of benefit to patients with Friedreich's ataxia or olivopontocerebellar atrophy.
