We studied the effects of D-cycloserine, a partial NMDA receptor allosteric agonist, on ataxia in patients with spinocerebellar degeneration. Fifteen Japanese ataxic patients enrolled in a 14-day single-blind trial of D-cycloserine (daily oral dose of 50 mg) following a 14-day single-blind placebo phase. At the end of the D-cycloserine administration, there was a significant reduction in the posture, gait and total score of the international cooperative ataxia rating scale and in the time for walking and speech tasks. D-Cycloserine was well-tolerated and no adverse effect was observed. D-Cycloserine may have therapeutic efficacy for spinocerebellar ataxia.
