 Traumatic brain injury, or TBI, afflicts more than 320,000 of our military heroes returning from combat. But today, thanks to a partnership between the Intrepid Fallen Heroes Fund and our armed forces, service members are being treated with a more than 90% success rate. One of those heroes, Major Steve Taylor, sustained a traumatic brain injury while serving in Afghanistan. He sought help after a change in his temperament and suffering from frequent headaches and loss of sleep.
