title: Acute chorea caused by valproate in an elderly.
abstract: We present the case of an elderly woman chronically treated with valproate as migraine prophylaxis. She developed acute chorea secondary to valproate dose increase. Choreiform movements ceased following valproate discontinuation. Chorea is a rare and dose dependent side effect of valproate.
