A neurosurgeon is a medical doctor who diagnoses and surgically treats conditions of the brain and central nervous system. Strokes, degenerative back disease and brain tumors are among the common health ailments a neurosurgeon treats. Vascular disorders and other brain infections are also treated by neurosurgeons.
The educational and training path to become a neurosurgeon is extensive. It normally takes four years to complete a pre-med undergraduate degree and then four more years to complete medical school. A one-year surgical internship is then followed by at least five years of residency in neurosurgery. Neurosurgeons who want to specialize in treating specific types of brain or nervous system conditions continue on for even more residency training.
