A synthetic hormone used to treat people with osteoporosis could also help some people with schizophrenia. Researchers from Monash University in Australia compared the effectiveness of the synthetic oestrogen raloxifene to a placebo. In a small-scale study involving post-menopausal women the drug was found to have a significantly greater impact on psychosis symptoms than a placebo and to enhance people's memory and learning capacity. The type of oestrogen used in the study does not have the side effects on breast, uterus and ovarian tissue associated with other forms of oestrogen.
