Clozapine treatment of spasmodic torticollis.
We report a trial of clozapine (CLO) in patients with spasmodic torticollis (ST). In an open-design trial we treated five patients with adult-onset ST with CLO (300 mg/d) over 12 weeks and one patient over 3 weeks. We videotaped the patients three times (before and at the end of CLO treatment, and 2 weeks after CLO withdrawal) according to a standardized protocol. At the end of the treatment period, CLO plasma concentrations ranged from 67 to 371 ng/ml. In all six patients, analysis of the video ratings and patients' self-assessments failed to reveal any improvement of ST. These preliminary results fail to confirm any therapeutic benefit of CLO in the treatment of ST.
