Chorea in Huntington disease improved with tetrabenazine

Chorea in Huntington disease improved with tetrabenazine

This woman with Huntington disease attempts to keep her tongue out but is interrupted by dyskinetic movements of her tongue, mouth, and jaw. She also exhibits severe generalized chorea. Following treatment with tetrabenazine, a dopamine-depleting drug, she is much improved. (Contributed by Dr. Joseph Jankovic.)
