 Huntington's disease (HD), which results from a mutation in chromosome 4, is marked by a decrease in the neurotransmitter (GABA, substance P, etc) level in the basal ganglia. Clinically, it is characterized by a triad of motor, cognitive, and psychiatric disturbances. Antipsychotic drugs, especially dopamine antagonists, have been shown to be effective in the control of these symptoms;however, their use is limited by the occurence of adverse effects that are characterized mainly by extrapyramidal symptoms.

 Here, we report the case of a 42-year-old woman with HD who presented with severe impulsive behavior, hallucinations, and delusions, in addition to severe chorea. After admission, we administered haloperidol (3mg/day);this led to an improvement in the psychomotor excitation. Three weeks after admission, she presented again with aggravated impulsive, hallucinations, and delusions. Her symptoms were alleviated by olanzapine (20mg/day) therapy. Eight weeks after admission, she was discharged from the hospital, and the symptoms have not recurred during the 1-year follow-up period. Therefore, we concluded that olanzapine appears to be useful in the teratment of psychiatric symptoms of HD.
