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 treating patients, neurologists often collaborate with other healthcare professionals to provide comprehensive care. They may also conduct research to better understand neurological disorders and develop new treatments. Their expertise is crucial for improving the quality of life for individuals with neurological issues.
