Robert A. Sweet, M.D. Dr. Sweet's research program is focused on understanding the mechanisms leading to the generation of psychotic symptoms (delusions and hallucinations) which may occur in multiple disorders. He and his colleagues have proposed that there are common genetic risk factors and vulnerable brain circuits that act together to cause psychotic symptoms in schizophrenia and Alzheimer Disease.
