Neurosurgery is a medical specialty that focuses on the diagnosis, surgical treatment, and rehabilitation of disorders affecting the nervous system, which includes the brain, spinal cord, peripheral nerves, and cerebrovascular system.

Neurosurgeons treat a variety of conditions that may require surgical intervention. Common conditions they manage include:

• Brain tumors
• Spinal cord tumors
• Traumatic brain injury
• Spinal cord injury
• Aneurysms
• Arteriovenous malformations (AVMs)
• Herniated discs
• Chronic pain (e.g., trigeminal neuralgia)
• Epilepsy
• Hydrocephalus

Neurosurgeons use a variety of diagnostic tools and procedures, such as MRI scans, CT scans, angiography, and neurophysiological monitoring, to assess and diagnose conditions. Treatment often involves complex surgical interventions, which can range from minimally invasive techniques to major surgeries, depending on the condition and patient needs.
