stress & premenstrual symptoms study

Conditions: PMDD; Stress; Mood

Summary: this study that aims to evaluate the psychophysiology of premenstrual mood disorders (pmds) at baseline and after treatment with sertraline. participants will include women with pmds and healthy female controls. participation involves a baseline visit to determine eligibility and three study visits that include questionnaires and stress reactivity assessment via an acoustic startle paradigm. female participants with pmds will receive sertraline during the premenstrual phase.

among women with premenstrual mood dysphoric disorder (pmdd), baseline arousal is heightened during the luteal phase of the menstrual cycle compared to the follicular phase, as measured by acoustic startle response (asr). healthy female controls do not show cyclic changes in this measure of physiologic arousal. it has been suggested that such heightened physiologic arousal during the luteal phase may be due to differences in neurosteroid modulation of gamma-aminobutyric acid (gaba)-a receptor function. research indicates that women with premenstrual mood disorders (pmds) may have sub-optimal sensitivity to the progesterone metabolite allopregnanolone (allo), a gaba-a receptor modulator. in animal models, intracerebroventricular injection of corticotrophin releasing factor (crf) increases amplitude of the acoustic startle response, while allo administration attenuates this crf-enhanced startle. the primary aim of this study is to examine differences in asr by menstrual cycle phase (follicular, luteal) and group (control, pmdd). secondary aim is to examine the impact of luteal phase treatment with a selective serotonin reuptake inhibitor (ssri) on psychophysiology in women with pmds. an exploratory aim is to examine immune function among these women.
