One widespread misconception is that neurosurgeons only operate on the brain. The American Association of Neurological Surgeons (AANS) claims that they often devote far more effort to treating disorders involving the spine than those involving the brain. Back pain, neck pain, sciatica, ruptured discs, degenerative diseases of the spine, brain and spinal malignancies, and stroke are among the common illnesses that neurosurgeons treat. Additionally, they cure illnesses that present symptoms in one part of your body but are actually related to a problem in the central nervous system because the nervous system stretches from your brain to your spine and your nerves branch out into every part of your body. For instance, an issue with your cervical spine may be connected to carpal tunnel syndrome symptoms (neck area).
