Menstrual Psychosis - Epidemiology

Epidemiology

There have been no state-of-the-art population-based surveys. The fragmentary data at present available suggest that this psychosis is much less common than puerperal psychosis (whose frequency is rather less than 1/1,000 pregnancies), and very much less common than menstrual mood disorder (which, strictly defined, affects about 5% of women). Its frequency at the threshold of hospital admission is probably about 1 in 10,000 women.

Most cases have been published by French, German, Japanese or American clinicians, but occasional reports of Indian, Iraqi, Egyptian, Vietnamese, Taiwanese and Bangladeshi women suggest a worldwide disorder.
