What are the differences between psychiatry and neuropsychiatry?

Type of training: Both psychiatrist and neuropsychiatrists (behavioral neurologists) both start with medical school. Psychiatrists focus on psychiatric disorders, most of which have no identified brain cause; neuropsychiatrists get additional training in neurology and focus on disorders that may have a defined brain problem such as a stroke that is causing or contributing the behavioral difficulties.

NeuroPsych.: Neuropsychiatry is a branch of medicine dealing with mental disorders attributable to diseases of the nervous system. It is a subspecialty of psychiatry , and also is closely related to behavioral neurology (a subspecialty of neurology). It focuses on problems of cognition & behaviors caused by brain disease or injury.

Neuropsychiatry: Is an integrative model involving neurology, psychiatry and neuropsychology. It is a clear understanding that the brain is a very complex organ and that each discipline is important in understanding it.
