A neurologist is a physician specializing in neurology and trained to investigate, diagnose and treat neurological disorders.
Neurologists diagnose and treat myriad neurologic conditions, including stroke, epilepsy, movement disorders such as Parkinson’s disease, brain infections, autoimmune neurologic disorders such as multiple sclerosis,
sleep disorders, brain injury, headache disorders like migraine, tumors of the brain and dementias such as Alzheimer’s disease.
Neurologists may also have roles in clinical research, clinical trials, and basic or translational research. Neurology is a nonsurgical specialty, its corresponding surgical specialty is neurosurgery.
