Brain imaging scans, also called neuroimaging scans, are being used more and more to help detect and diagnose a number of medical disorders and illnesses. Currently, the main use of brain scans for mental disorders is in research studies to learn more about the disorders. These researchers study healthy brain development, effects of mental illnesses, or effects of mental health treatments on the brain. Brain scans alone cannot be used to diagnose a mental disorder, such as autism, anxiety, depression, schizophrenia, or bipolar disorder (NIMH, 2010). Brain neuroimaging helps researchers study healthy brain development, effects of mental illnesses, or effects of mental health treatments on the brain.
