A neurologist is a medical doctor who specializes in diagnosing and treating disorders of the nervous system. This includes conditions affecting the brain, spinal cord, and nerves, such as epilepsy, multiple sclerosis, and Parkinson's disease. Neurologists use various tests, including imaging studies and neurological exams, to assess patients' conditions. In addition to diagnosing illnesses, neurologists also develop treatment plans that may involve medications, therapies, or referrals to other specialists. They play a crucial role in managing chronic neurological conditions and improving patients' quality of life through ongoing care and support.
