If you get a concussion but didnt get unconscious, is it considered a traumatic brain injury? what is the definition of traumatic brain injury?thankd

MTBI: Technically a concussion is a mild Traumatic Brain Injury (mTBI). It is typically a clinical diagnosis, usually used when someone has sustained trauma to the head associated with at least a brief loss of consciousness (LOC) and without any signs of injury on CT scan. You can extend this diagnosis to patients without LOC who experience other symptoms such as headaches following the trauma.
