The effects of the nootropic drug piracetam and its analogue, the antiepileptic drug levetiracetam (ucb L059) on severity of dystonic attacks were studied in a mutant hamster model of idiopathic generalized dystonia. Both drugs significantly decreased the severity of dystonia. In contrast to seizure models, in which levetiracetam is much more potent as an anticonvulsant than piracetam, the antidystonic potency of levetiracetam was only moderately higher than that of piracetam. The antidystonic activity of piracetam and levetiracetam was not associated with any behavioral side effects. The data indicate that piracetam and levetiracetam are interesting novel treatments for idiopathic dystonia.
