A mild traumatic brain injury,or concussion,is an alteration in neurological or cognitive function with or without loss of consciousness,which occurs immediately after a head injury.Petechial hemorrhages along the superficial aspects of the brain at the point of impact are a type of contusion but are not necessarily associated with amnesia.A contusion is visible bruising and tearing of cerebral tissue.A contrecoup is a lesion that develops remote from the site of trauma as a result of an acceleration/deceleration injury.
