Brain surgery, also known as neurosurgery, is a medical specialty that involves the surgical treatment of conditions affecting the brain, spinal cord, and nervous system. This type of surgery is often performed to treat conditions such as brain tumors, traumatic brain injuries, vascular disorders, epilepsy, and Parkinson's disease. The goal of brain surgery is to alleviate symptoms, improve brain function, and in some cases, save the patient's life. Neurosurgeons use specialized techniques and equipment to carefully access and operate on the brain, working to minimize risks and maximize outcomes for patients.
