“…However, women who have experienced puerperal psychosis are at risk of developing further puerperal and non-puerperal episodes of illness (e.g., Reich & Winokur, 1970;Schopf, Bryois, Jonquiere & Le, 1984). Presently, it is not possible to give an accurate assessment of risk, although it has been estimated that in women who have previously experienced an episode of puerperal psychosis the rates of puerperal relapse are estimated between 17% and 50% (e.g., Brockington, 1996) and 39% and 81% for non-puerperal relapse of illness (Kirpinar, Coskun, Caykoylu, Anac, & Ozer, 1999;Protheroe, 1969).…”
