Psychiatry and neurology are two medical specialties that focus on the health and treatment of the brain and nervous system. Psychiatrists are medical doctors who specialize in the diagnosis, treatment, and prevention of mental illness and emotional disturbances. They use medical, psychological, and social interventions to help their patients. Neurologists, on the other hand, are specialists in the diagnosis and treatment of diseases of the nervous system, which includes the brain, spinal cord, and peripheral nerves. They focus on the medical management of conditions such as Alzheimer’s disease, Parkinson’s disease, seizures, multiple sclerosis, and stroke.
