<unk>  <unk>  occurs when physical trauma causes brain damage.<unk>  can result from a blunt head trauma or a penetrating head injury and is one of two subsets of acquired brain injury (ABI).  The other subset is non-traumatic brain injury, or injuries that do not involve external mechanical force (e.g. stroke, meningitis, anoxia).  Parts of the brain that can be damaged include the cerebral hemispheres, cerebellum, and brain stem.<unk>  can be mild, moderate, or severe, depending on the extent of the damage to the brain .<unk>  can cause a host of physical, cognitive, emotional, and social effects. Outcome can be anything from complete recovery to permanent disability or death. Long term sequelae however, can be difficult to assess because of co-existing neurologic issues such as a stroke or degeneration as well as the different interpretation of questions in scoring models by patients and scales may not capture the complete clinical picture.
