Concussion is the caused by an injury to the head. It is the most common form of traumatic brain injury. Other terms include mild brain injury, mild traumatic brain injury (MTBI), mild head injury (MHI), and minor head trauma. People suffering from it are usually monitored in hospital. The main reason for this is that hemorrhage in the brain is common; this can be life-threatening.
Symptoms last three to seven days in minor cases, but they usually take ten to 25 days to go away.
