The incident that caused the
concussion can often be accompanied by structural damage to brain tissue, as well as the rupture of
blood vessels, which can cause a bleed. This is what Drnee refers to as underlying brain injury. The bleed may be slow and continue for several days, or even weeks. A concussion is a specific syndrome secondary to a blow to the head. Impacts to the skull that produce a concussion can certainly cause death, if not quickly addressed in an appropriate medical facility.
