Traumatic Brain Injury is a condition which results from sudden damage to the brain, caused by a blow or a jolt to the head. Generally, the common cause is usually a car or motorcycle crash, sports injury, fall, or assault. Sometimes, there might be only a concussion, but in severe cases, there might be permanent brain damage. In mild cases, rest and medication might be enough, but severe traumatic brain injury cases might require rare and life-saving surgery. People who survive a brain injury may face lasting effects in their physical as well as mental abilities. They might also show emotions and personality changes. Some people might need rehabilitation to recover as well as relearn skills.
