(33,424 posts)I just looked up what they call "traumatic brain injury." It is basically every injury, no matter how minor, to the head.
In 2010 2.5 million TBIs occured either as an isolated injury or along with other injuries.
A TBI is caused by a bump, blow or jolt to the head or a penetrating head injury that disrupts the normal function of the brain. Not all blows or jolts to the head result in a TBI. The severity of a TBI may range from mild, i.e., a brief change in mental status or consciousness to severe, i.e., an extended period of unconsciousness or amnesia after the injury. \
So 2.5 million! a year. What unscientific garbage statistics. Meant to scare and nothing else. Everything is a TBI now.
