Neuropsychiatry is a field of medicine that combines neurology and psychiatry to study and treat mental disorders that are related to problems with the nervous system. Neuropsychiatrists are doctors who have expertise in both brain and mind, and who can diagnose and treat patients with conditions such as autism, ADHD, Tourette’s syndrome, dementia, epilepsy, stroke, brain injury, and others. Neuropsychiatry is based on the idea that the mind and the brain are not separate entities, but different ways of looking at the same system. By understanding how the brain functions and how it affects behavior, emotions, cognition, and perception, neuropsychiatrists can help patients improve their quality of life and well-being.
