Aug. 4 (Bloomberg) -- Estrogen may ease the symptoms of schizophrenia in women with severe disease, according to an Australian study in the Archives of General Psychiatry. Researchers started focusing on estrogen’s links to schizophrenia about two decades ago when it became clear that female patients typically fell ill an average of about five years after males. Symptoms also tend to worsen after childbirth and menopaus when estrogen levels retreat, and lessen during menstruation and pregnancy when hormones levels are high.
