Neurology is the study of the nervous system and the treatment of nervous system diseases and injuries. The nervous system is an extensive network that includes the brain, spinal cord, the cranial and spinal nerves, and the autonomic nerves that exist throughout the body. Neurologists are concerned with traumatic injury to the nervous system (head injuries, pinched nerves, neck injuries, etc.), conditions such as migraine headaches as well as disorders affecting the system such as degenerative nerve diseases and Parkinson's disease.
Migraine headache sufferers often receive treatment from neurologists. A great deal of research has been conducted on this condition, and new advances in medications and alternative management techniques are being made all the time. Some neurologists devote practices exclusively to the treatment of migraines.
