Mild brain injury can be recovered after standardized treatment, while severe brain injury is more difficult to recover. 1. Mild brain injury: the degree and scope of brain injury is relatively light, such as concussion, focal cerebral contusion, etc., the location of the injury is in the non-functional area, and the sequelae are relatively small, and it can be recovered after timely and standardized treatment. 2. Severe brain injury: the scope of brain injury is relatively large, and the location of brain injury is in the brainstem, basal ganglia, thalamus, motor function center, etc. Under active treatment, the symptoms can be relieved, but it is easy to bring different degrees of sequelae to the body, such as coma, paralysis, epilepsy, hydrocephalus, etc., which is more difficult to recover. Once not treated in time or effectively, life may also be in danger. Brain injuries are often caused by external forces, and when brain damage occurs, you should immediately seek medical attention to help recover from brain injuries through the right treatment program.
