Neurological conditions include diseases caused by faulty genes, degenerative diseases, diseases of blood vessels that supply the brain, injuries to the brain, seizure disorders, brain tumors, and brain infections, as well as developmental disorders. All of these conditions have a huge neuropsychological, psychosocial, and quality-of-life impact and represent a global public health challenge [1]. Neurosurgical options for diseases of the nervous system continue to expand in breadth and scope. These advances have been related in large part to progress in technology, translational application of molecular biology, and increased understanding of the physiological processes associated with neurological disease. Unfortunately, interventional surgical brain procedures can result in unavoidable secondary acute and delayed neurocognitive and neurological deficits.
