Tiapride in the treatment of Huntington's chorea

Twenty-two patients with Huntington's chorea were investigated in a double-blind controlled cross-over trial. The effect was measured by counting the number of involuntary movements from video-recordings and by a Doppler-radar device. Besides these methods, subjective assessments were made on analogue scales by patients, family, nurses and attendant doctors. The quantitative methods revealed no significant diminution of the involuntary movements in the Tiapride therapy period. The subjective evaluation turned out to be useless because of many inconsistent answers.
