A neuropsychologist is a psychologist who completed specialty training in cognitive assessment and brain behavior relationships. Psychologists also perform evaluations, but typically for behavioral health conditions, whereas neuropsychologists evaluate individuals with neurological disorders. Psychologists conduct therapy/counseling while neuropsychologists usually do not. Neuropsychologists can also sometimes be confused with psychiatrists or neuropsychiatrists. Psychiatrists are medical doctors who treat behavioral health conditions. Importantly, psychiatrists prescribe medication whereas neuropsychologists do not.
