Neuropsychiatry is a branch of medicine that focuses on the relationship between neurological disorders and psychiatric symptoms. It involves the diagnosis and treatment of individuals who experience both neurological and psychiatric conditions, such as epilepsy, stroke, Parkinson's disease, and schizophrenia. Neuropsychiatrists aim to understand the underlying biological mechanisms that contribute to these complex disorders and develop appropriate treatment plans that address both neurological and psychiatric symptoms. This field requires a multidisciplinary approach, drawing upon expertise from neurology, psychiatry, neuropsychology, and other related disciplines.
