Brief Summary
Premenstrual dysphoric disorder (PMDD) is a severe affective disorder impacting millions of women worldwide, thought to be due to altered sensitivity to hormone fluctuations across the menstrual cycle. Neuroactive steroid hormones (NAS) and the gamma-aminobutyric acid (GABA)-A receptor (GABAAR) are thought to play a role in PMDD. This research will assess the blood levels of GABAergic NAS, expression of associated enzymes, and expression of GABAAR subunits across the premenstrual (luteal) phase of the menstrual cycle in healthy controls and individuals with PMDD. Within the PMDD group, the investigators will assess how these measures are affected by a low-dose antidepressant medication versus placebo. The results will provide a comprehensive view of the changes in these systems across the menstrual cycle and will add to the investigator's understanding of the mechanisms that underlie PMDD, as well as therapeutic mechanisms of PMDD treatment.

Outcome Measures
Primary Outcomes (1)
Neuroactive Steroid Levels
The primary outcome variable is levels of neuroactive steroids in blood; from the early luteal phase (2 days post ovulation) compared to the late luteal phase (days 5 to 1 prior to predicted menses onset)
Post ovulation up to 2 days, up to 5 days pre-menses prediction
Secondary Outcomes (2)
Neurosteroidogenic enzyme expression levels
First menstrual cycle, up to 3 months
GABAAR subunit expression levels
first menstrual cycle, up to 3 months
Study Arms (3)
Control
NO INTERVENTIONParticipants delegated to the "control" arm will be individuals without premenstrual symptoms in the luteal phase of the menstrual cycle. Participants will be asked to track mood across the menstrual cycle, answer self-report surveys, and complete four blood draws.
PMDD with sertraline
ACTIVE COMPARATORParticipants delegated to the "PMDD with sertraline" arm will be individuals with severe premenstrual symptoms in the luteal phase of the menstrual cycle. Participants will be asked to track mood across two menstrual cycles, answer self-report surveys, and complete eight blood draws (four in each menstrual cycle). In the second cycle, participants in this arm will take a daily pill of 50 mg of sertraline from ovulation until menses onset (end of menstrual cycle 2).
PMDD with placebo
PLACEBO COMPARATORParticipants delegated to the "PMDD with placebo" arm will be individuals with severe premenstrual symptoms in the luteal phase of the menstrual cycle. Participants will be asked to track mood across two menstrual cycles, answer self-report surveys, and complete eight blood draws (four in each menstrual cycle). In the second cycle, participants in this arm will take a daily placebo pill from ovulation until menses onset (end of menstrual cycle 2).
Interventions
The intervention will be in the form of an oral pill, taken daily, from the day of positive urine ovulation test result until the day of menses onset.
The placebo oral tablet will be of the same shape, color, and manufacturer as the sertraline 50 mg oral tablets. Tablet will be taken daily, from the day of positive urine ovulation test result until the day of menses onset.
