Introduction Premenstrual dysphoric disorder (PMDD) is a severe and disabling form of premenstrual syndrome affecting 3–8% of menstruating women. The relationship between PMDD and psychiatric disorders is still unclear. Aim The aim of this study was to assess the prevalence and symptoms of PMDD in a sample of psychiatric patients. Patients and methods A sample of psychiatric outpatients and inpatients who attended for treatment was clinically diagnosed according to Diagnostic and Statistical Manual of Mental Disorders-5 by clinical interview and by applying the premenstrual symptoms screening tool for diagnosis of PMDD. Results The prevalence of PMDD among cases and controls was 40.5 and 7.6%, respectively. PMDD was most prevalent among depressed patients (96.4%) followed by those with bipolar diseases (38.5%) and was less frequent among anxiety and psychotic patients (4.5 and 1.8%, respectively). Conclusion PMDD is highly related to psychiatric disorders especially depression and bipolar disorder.
