Neurologists are medical doctors who specialize in diagnosing and treating disorders of the nervous system, which includes the brain, spinal cord, and nerves. They manage conditions such as epilepsy, multiple sclerosis, and Parkinson's disease. Neurologists often use various tests, including MRI scans and electroencephalograms (EEGs), to assess patients' neurological health. In addition to treating diseases, neurologists also conduct research to better understand the nervous system and develop new therapies. They may work in hospitals, clinics, or academic settings, collaborating with other healthcare professionals to provide comprehensive care for patients with neurological issues.
