title: Tetrabenazine for hyperglycemic-induced hemichorea-hemiballismus.
abstract: We reported a 74-year-old woman with new-onset diabetes mellitus who presented with the sudden onset of mild left hemiparesis and marked left hemichorea-hemiballismus. Brain CT scan and MRI showed T1W, T2W, and DWI lesions in the right putamen and caudate, which have been previously reported in cases of hyperglycemic-induced hemichorea-hemiballismus (HIHH). The patient dramatically responded to tetrabenazine within a day. Subsequent dose reductions lead to a reemergence of symptoms. Tetrabenazine improves a variety of hyperkinetic movement disorders but, to our knowledge, its use has never been reported for HIHH.
