This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.
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.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
