Traumatic brain injury is the disruption of normal brain function resulting from head trauma. In order to be classified as traumatic brain injury, individuals must experience a loss of consciousness at the time of injury, memory loss, confusion or stroke like symptoms. These symptoms can be temporary or permanent. Motor vehicle accidents are the leading cause of traumatic brain injury and it is not surprising that alcohol use is associated with an increased risk of traumatic brain injury. Men are twice as likely as women to experience traumatic brain injury.
