Abstract
Objective:
The authors studied the effects of vitamin E treatment of tardive dyskinesia; earlier studies have produced contradictory results.
Method:
Twenty-eight patients with tardive dyskinesia were treated in a double-blind, parallel-group comparison study of 8-12 weeks of treatment with vitamin E (1600 IU/day) or matching placebo capsules.
Results:
The Abnormal Involuntary Movement Scale scores of the patients treated with vitamin E improved significantly compared to the scores of the patients given placebo.
Conclusions:
These results support earlier findings of the efficacy of vitamin E in treating tardive dyskinesia.
