A neuropsychiatrist is a medical doctor who specializes in the diagnosis and treatment of mental disorders that have a neurological basis or origin. They have specialized training in both neurology and psychiatry, allowing them to understand and treat complex conditions that involve both the brain and the mind.

Neuropsychiatrists often work with patients who have conditions such as dementia, traumatic brain injuries, epilepsy, stroke, and Parkinson's disease, all of which can have significant effects on a person's mental health. They also work with patients who have psychiatric disorders such as schizophrenia, bipolar disorder, and major depressive disorder, among others.

To become a neuropsychiatrist, a person must complete medical school and then complete a residency in both neurology and psychiatry. This can take a minimum of 5-6 years, followed by additional fellowship training in neuropsychiatry. Neuropsychiatrists may work in hospitals, clinics, or private practice, and often work collaboratively with other healthcare professionals to provide comprehensive care to their patients.

There are several types of neuropsychiatrists, each with their own areas of focus and expertise. Here are some of the main types:

• Adult Neuropsychiatrists: These doctors specialize in diagnosing and treating neurological and psychiatric conditions in adults.
