The number of US troops who have suffered wartime brain injuries may be as high as 360,000 and could cast more attention on such injuries among civilians, Defense Department doctors said yesterday.
The estimate of the number injured - the vast majority of them suffering concussions - represents 20 percent of the roughly 1.8 million men and women who have served in Iraq and Afghanistan, where blast injuries are common from roadside bombs and other explosives, the doctors said.
