Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Female participants, aged 18-45, will receive daily sessions of Theta-burst stimulation (TBS) applied over 5 continuous days in the luteal phase (10 +/- 2 days after ovulation) in the treatment phase (Month 3 of study). TMS will be administered at the Monash Alfred Psychiatry Research Centre (MAPrc) by trained research staff.

Stimulation is applied to the left dorsolateral prefrontal cortex (DLPFC), located using standard methods adjusting for head size. Stimulation intensity will be at 120% of the individual’s calibrated resting motor threshold.

Eligibility
Key inclusion criteria
1. Meet the DSM-5 diagnostic criteria for Premenstrual Dysphoric Disorder (PMDD).

3. Report of at least a one-year history of regularly experiencing PMDD symptoms.
4. Women taking the oral contraceptive pill (OCP) or using a hormonal intrauterine device (IUD) are required to have commenced the same OCP or IUD at least 3 months prior to their enrolment, while continuing to meet criteria 1 and 2 above at the time of study consent.
