A neurologist is a medical professional who specializes in treating diseases of the nervous system. The nervous system is made of two parts: the central and peripheral nervous system. Their main specialist is related to the brain and spinal cord. Illnesses, disorders, and injuries that involve the nervous system often require a neurologist’s management and treatment. People having problems related to their senses, such as touch, vision or smell may also need to see a neurologist. Some of the subspecialists include headache medicine, neuromuscular medicine, neurocritical care, neuro-oncology, geriatric neurology, autonomic disorders, vascular (stroke care), child neurology, etc.
