Study aims to identify schizophrenics at risk for type 2 diabetes

... percent, it just changes your risk; bad things in utero increase the risk of diabetes and the risk of schizophrenia. It may be they are going to be associated because the same bad things cause both," says Dr. Kirkpatrick. The bottom line of the study of newly diagnosed schizophrenics is to see whether...
