A new brain imaging study of recently diagnosed schizophrenia patients has found, for the first time, that the loss of gray matter typically experienced by patients can be prevented by one of the new atypical antipsychotic drugs, olanzapine, but not by haloperidol, an older, conventional drug. The study, published in today’s Archives of General Psychiatry, also confirmed previous studies that show patients who experience less brain loss do better clinically. “This is a really big breakthrough,” says the study’s leader, Jeffrey Lieberman, M.D., director of the New York State Psychiatric Institute and chairman of psychiatry at Columbia University Medical Center. “The drugs we have for schizophrenia can’t cure people who’ve been sick for years, but this study shows that the newer atypical drugs, if started early, can prevent the illness from progressing. If our findings are confirmed, one could argue that we should treat new patients with atypical drugs like olanzapine rather than older conventional medications such as haloperidol and chlorpromazine.”
