When you think of what might cause a brain injury, you typically think of a very serious accident involving a direct blow to the head, like falling off a bike and landing on your head. Or, you may think of professional sports, namely football, where numerous blows to the head have been shown to cause long-term brain injuries.
The reality, though, is that brain injuries can be much more subtle than what you think, and the leading cause of such injuries is car accidents.
Traumatic brain injury (TBI) is sudden damage to the brain caused by a blow or jolt to the head. During the impact of an accident, the brain crashes back and forth inside the skull causing bruising, bleeding, and tearing of nerve fibers. The resulting injuries range from a mild concussion to permanent brain damage.
A concussion is the most likely result from a TBI, and it can result in anywhere from an near-instantaneous loss of consciousness to up to 15-20 minutes of a loss of consciousness.
