Brain+Injuries

= Brain Injuries =

=== Every 15 seconds, someone in the United States suffers from a brain injury. Of the 100,000,000 people that are treated in the emergency room because of a traumatic brain injury (TBI), 50,000 people die, and 80,000 have permanent disabilities. Brain injuries occur more frequently than breast cancer or AIDs. 1 out of every 50 Americans are living with a disability from TBI currently. You do not have to be knocked unconscious to sustain a brain injury. If you have repeated minor brain injuries, this can lead to a big problem and cause a disability or even death. People between the ages of 15-24 who drive a motorcycle, ride a bike, or play sports are at the top of the risk list for head injuries. Men are twice as likely as women to injure their heads. Transportation injuries are the reason for half of all head injuries. Girls under 10 were found to be four-times more likely to die of brain injury. Boys, having more testosterone, seem to be less at risk of experiencing head injuries because the testosterone can bulk up their brain, just like how it bulks up their muscles. Also for young women, high levels of estrogen can help them prevent head injuries. Once you get to your 50-70s, women are twice as likely to survive a traumatic head injury. Even though kids who have head injuries recover rapidly, they can have many problems later in life. ===

**Brain injury consists of primary and secondary events. Primary brain injuries such as fractures, bruises, blood clots, lacerations of brain tissue or blood vessel, are more or less complete at the time of impact. But, a secondary cycle of biochemical events is set in motion by the trauma and is the major contributor to long-term deficits associated with brain injury.**

=== Right behind your forehead is the prefrontal cortex, this is where the basic human qualities are affected. Damage here can lead to personality changes that manifest in impulsive and socially inappropriate behavior, depression, and violence. ===
