text: <unk>  falls under the classification of mild traumatic brain injury (MTBI). It is not clear whether<unk>  is implied in mild brain injury or mild head injury. "MTBI" and<unk> " are often treated as synonyms in medical literature. However, other injuries such as intracranial hemorrhages (e.g. intra-axial hematoma, epidural hematoma, and subdural hematoma) are not necessarily precluded in MTBI or mild head injury, but they are in<unk> . MTBI associated with abnormal neuroimaging may be considered "complicated MTBI".<unk> " can be considered to imply a state in which brain function is temporarily impaired and "MTBI" to imply a pathophysiological state, but in practice few researchers and clinicians distinguish between the terms.  Descriptions of the condition, including the severity and the area of the brain affected, are now used more often than<unk> " in clinical neurology.
