Levetiracetam for tardive dystonia: A case report

摘要

Sir, Tardive syndrome (TS) is a group of hyperkinetic or hypokinetic movement disorders and sensory symptoms sharing the same pathophysiological basis. This neurological disorder most frequently occurs as the result of long-term or high-dose use of antipsychotic drugs. The etiological theories and treatment strategies have been elucidated recently. Of late, levetiracetam is gaining importance as a novel therapeutic agent for TS. This report presents a case of trifluoperazine-induced tardive dystonia who partially responded to adjunctive treatment with levetiracetam.
