Chorea due to gabapentin monotherapy in a not encephalopatic patient.

Dr. Carlos Alexandre Twardowschy – Rua Dias da Rocha Filho 261 / 11 80040-050 Curitiba PR Brasil. E-mail: [email protected] In the past 10 years the armamentarium of antiepieleptic drugs (AEDs) has almost doubled. With some exceptions, movement disorders are relatively rare in patients using these drugs. In fact, they have become increasingly used to treat some types of movement disorders. Among the newer AEDs, gabapentin was associated with choreoathetosis in several patients in postmarketing reports frequently associated with others AEDs or in patients with encephalopathy. We report the case of a 68-years-old woman, neurologically normal, who developed choreoathetoid movements after gabapentin monotherapy.
