Neurofeedback Treatment of Affective Instability in Premenstrual Dysphoric Disorder(PMDD)

Premenstrual Dysphoric Disorder (PMDD) is characterized by affective instability and irritability, diagnosed in 5% of reproductive-age women. Although causing severe insult to patients' functioning and quality of life, \~40% do not respond to conventional treatment options. In this study, the investigators aim to examine a novel therapeutic approach for the treatment of affective instability in PMDD: brain-guided training (i.e.NeuroFeedBack, NF) probed by prefrontal EEG alpha asymmetry. PMDD patients will be randomly assigned to either a real or sham EEG-NF protocol, and undergo simultaneous fMRI-EEG scans before and after training period. Comprehensive psychological assessment will be performed for outcome measure. The investigators hypothesize that EEG-NF treatment will enhance affective stability, thus improving patients' daily lives.
