A neurologist is a medical doctor who specializes in diagnosing and treating disorders of the nervous system. This includes the brain, spinal cord, and nerves throughout the body. Neurologists help patients with conditions like epilepsy, multiple sclerosis, and Parkinson's disease. They use various tests, such as MRIs and EEGs, to understand what might be causing a patient's symptoms. In addition to treating these conditions, neurologists often work closely with other healthcare professionals, such as neurosurgeons and psychiatrists, to provide comprehensive care. They play a crucial role in helping patients manage their neurological issues and improve their quality of life.
