Unlike the past in the early and mid-20th century between 1916 and 1964, neurosurgery was considered more complex and highly dexterous. Henceforth, neurosurgeons with limited knowledge on how critical a surgical procedure was going to be and complications that may arise, turned down the idea of practical surgery and focused more on the non-surgical treatments like the therapies such as “neuropsychology” and “neurofeedback”, and pharmaceuticals. In this situation, doctors studied the effects that the diseases of the nervous system had psychologically on the patients, and administered medications such as corticosteroids to suppress the effects (Goodtherapy, 2018). Nevertheless, neurosurgery is completely at the dawn of a new era where it is branching constantly into finding new ways to treat diseases that were never thought to be surgical in nature. For instance, functional neurosurgeons are regularly treating Parkinson’s disease with the use of Deep Brain Simulation (DBS) as well as tremor and there are dozens of ongoing trials for diseases from Alzheimer’s to depression. These advancements are progressive and continually keep changing and improving.
