Neurosurgery (or neurological surgery) is the medical specialty concerned with the prevention, diagnosis, treatment, and rehabilitation of disorders which affect any portion of the nervous system including the brain, spine, spinal cord, peripheral nerves, and extra-cranial cerebrovascular system.
Neurosurgery is the specialized field of surgery that treats diseases that affect the CNS—the brain and the spine. A Neurosurgeon is a medical doctor who has received extensive training in the surgical and medical management of neurological diseases.
The field of neurosurgery is one of the most sophisticated surgical specialties and encompasses advanced surgical and imaging technology and new research in molecular neurosurgery and gene therapy. There are five general categories of neurosurgical diseases that are commonly managed by neurosurgeons: cerebrovascular (hemorrhage and aneurysms); traumatic head injury (THI) (traumatic injury caused by accident); degeneration diseases of the spine; tumors in the CNS; functional neurosurgery; surgery for congenital abnormalities; and neurosurgical management of the CNS.
