title: The relationship of circulating estradiol to tardive dyskinesia in men and postmenopausal women.
abstract: In order to assess the relationship between tardive dyskinesia (TD) and baseline circulating concentrations of estradiol, prolactin and homovanillic acid, we studied 43 outpatient men and postmenopausal women on chronic antipsychotic medication. Serum estradiol did not correlate with severity of TD, antipsychotic medication dose, serum prolactin or plasma HVA. Multiple regression analysis indicated a significant relationship between plasma HVA and severity of TD in postmenopausal women. These findings support the hypothesis that estrogen might serve a protective role against neuroleptic-induced striatal dopamine pathology.
