The types of diseases that brain surgery looks at are basically related to brain disorders and can be treated as such. It is important to make specific judgments based on the specific condition, each condition is different, and there are even diseases that manifest elsewhere, but if the cause of the disease is in the brain, brain surgery is also needed for the diagnosis and treatment. The most common traumatic brain injuries include scalp hematoma, cerebral contusion, subdural hematoma and epidural hematoma; the most common cerebrovascular diseases include cerebral hemorrhage, cerebral infarction, and subarachnoid hemorrhage; the most common functional brain disorders include epilepsy, facial spasms, and trigeminal neuralgia; the most common neoplastic brain disorders include acoustic neuromas, meningiomas, glioma, and pituitary tumors; and the most common neoplastic brain diseases include acoustic neuromas, meningiomas, and pituitary tumors; and the most common brain disorders are brain surgery, which may require treatment. Pituitary tumors; common infectious diseases of the brain, such as viral encephalitis, septic encephalitis, tuberculous encephalitis; and some spinal cord diseases, neurosurgery can also treat, such as occipital foramen magnum malformation, cervical cord injury, cervical vertebrae fracture, cervical spondylosis, etc. Therefore, for brain surgery, it is possible to treat the disease. Therefore, there are relatively more diseases that can be treated by neurosurgery, which must be analyzed according to the specific conditions, and it is better to find local medical personnel to make a clear diagnosis of the condition.
