Neurosurgery is the surgical treatment of nervous system disorders related to brain, vertebral column, spinal cord, and peripheral nervous system and the symptoms are many. Modern neurosurgery is quite different from the conventional neurosurgery procedures. Today, doctors recommend minimally invasive neurosurgery that causes less discomfort, less pain, involves low risk, and a shorter Hospitals stay. But such a neurosurgery can prove expensive and not all hospitals are equipped with all the advanced facilities facilitating such a treatment.It is a blend of medical technological advancement and surfacing of highly trained neurosurgeons that modern neurosurgery has greatly benefited from. Advancement in microsurgery, magnetic resonance imaging (MRI), computer assisted imaging computed tomography (CT), magneto encephalography (MEG), positron emission tomography (PET), etc. have made it possible for surgeons to diagnose beforehand and find out the accurate cause of the disease as well as the exact place where the surgery is to be done.
Further the development of stereo tactic surgery is another added milestone in modern Neurosurgery. Expert surgeons today can perform more complicated surgeries; worth mentioning are radio surgery and endovascular surgery. In case of radio surgery, gamma knife and cyber knife are used and endovascular surgery is recommended for treatment of aneurysms.
