The U.S. military is opening a new medical center in suburban Washington dedicated to traumatic brain injury, sometimes called the signature wound of today’s wars.

The $65 million National Intrepid Center of Excellence at the National Naval Medical Center in Bethesda was built with private funds by the Intrepid Fallen Heroes Fund.

The New York-based charity is turning the building over to the military on Thursday.

Brain injuries are common among service members who have been exposed to blasts from the bombs used by insurgents in Iraq and Afghanistan.

The center will test new treatment methods and introduce patients and their families to services available for those suffering from brain damage and psychological problems.
