Brain patterns may predict schizophrenia behaviors

British researchers may have found a way to predict how people who suffer from schizophrenia will behave during a psychotic episode. Investigators compared the brain activity of 15 healthy volunteers before and after they were given ketamine, a psychosis drug that mimics schizophrenia symptoms. They found that increased brain activity during some tasks in the normal state predicted behaviors such as strange perceptions or disordered thoughts after participants took the drug. Scientists say these findings may explain why schizophrenia symptoms vary widely and may suggest new personalized treatments.  Read full story >
