title: Estrogen replacement and tardive dyskinesia.
abstract: A double-blind randomized clinical trial was conducted among 10 post-menopausal women with tardive dyskinesia (TD) to test the effect of estrogen replacement of the severity of abnormal movements and other outcome variables. After 3 weeks of treatment, the mean Abnormal Involuntary Movement Scale (AIMS) score decreased by 38% in the estrogen group and by 9% in the placebo group; the difference between groups was marginally significant (p less than 0.10). However, the small sample size and the imbalance between groups in baseline AIMS scores do not allow us to rule out the confounding effects of other prognostic factors. There were no significant differences between treatment groups for parkinsonian and psychological symptoms at any visit or for changes in these variables between visits. The findings of this preliminary trial are consistent with the results of other human and animal investigations, and they support the need for future research to understand the role of estrogens in the neuropathology and treatment of TD.
