Neuropsychiatry is a branch of medicine that deals with mental disorders attributable to diseases of the nervous system. It preceded the current disciplines of psychiatry and neurology, which had common training. neuropsychiatry has become a growing subspecialty of psychiatry and it is also closely related to the field of behavioral neurology, which is a subspecialty of neurology that addresses clinical problems of cognition and/or behavior caused by brain injury or brain disease of different etiologies. Neuropsychiatry is a field that both explores brain behavior relationships and focuses on the assessment and treatment of patients who have neurologic disorders along with cognitive, emotional, and/or behavioral problems. The Neuropsychiatric Conditions includes Addictions, Childhood and development, Eating disorders ,Degenerative diseases, Mood disorders, Neurotic disorders, Psychosis, Sleep disorders. Depending on the nature of the patient's complaints, we might do a psychiatric evaluation, a neuropsychiatric evaluation, a psychoeducational evaluation or a formal neuropsychological evaluation. Neuropsychiatric treatments include counseling, advice advocacy and medication treatment. Most of the treatments at NCN are administered by physicians assistants or nurse practitioners under the supervision of an attending psychiatrist or neuropsychiatrist. The physicians at NCN also see certain patients on a regular basis, but they are usually our most challenging patients. The psychiatrists tend to spend more time with new referrals and difficult diagnostic questions. They also have to work closely with the PAs and nurse practitioners when their patients are in difficulty or the course of their treatment takes an untoward turn.
