Neurosurgery is concerned with the surgical treatment of diseases of the nervous system. In consultation with neurologists, neurosurgeons investigate problems resulting from disorders of the nervous system. Neurosurgeons can operate on brain tumours, spinal cord tumours, herniated discs of the cervical and lumbar spine or cerebral haemorrhages (bleeding in the brain) and undertake surgical treatments of pain.

Neurosurgery is optimized by microsurgery with the aid of a surgical microscope. This technique allows more precise and minimally invasive surgery.
