title: Blunted serotonin response to fenfluramine challenge in premenstrual dysphoric disorder.
abstract: OBJECTIVE
  Indirect evidence suggests that abnormalities in serotonergic function may be involved in the pathogenesis of premenstrual dysphoric disorder. The goal of this study was to test the hypothesis of serotonergic deficiency in premenstrual dysphoric disorder by measuring the prolactin response to fenfluramine.
  
  
  METHODS
  The authors administered the serotonin-releasing drug dl-fenfluramine in a placebo-controlled protocol to nine women with premenstrual dysphoric disorder and 11 healthy female volunteers in the luteal phase of the menstrual cycle.
  
  
  RESULTS
  Compared to the normal subjects, the women with premenstrual dysphoric disorder had a significantly blunted prolactin response to fenfluramine.
  
  
  CONCLUSIONS
  Premenstrual dysphoric disorder appears to be associated with serotonergic deficiency.
