* Brain injuries are common in any activity where violent physical contact is a part of that activity. * Any trauma or injury to the brain causes changes to the brain, that result in changes for the individual. * The individual changes can be very minor and for the most part, not noticeable or, they can be very traumatic and impossible not to notice. * The effects of traumatic brain injuries are accumulative, that is the more injuries your brain receives, the more it is effecte4d and the more your life changes (extreme life changes can be experienced by "one" traumatic brain injury) . * Because of the way the brain sits in the skull it is very difficult, if not impossible to keep it from being injured as it violently contacts the inside surfaces of the skull. * For the most part helmets do not protect the brain.
