Iran war renews concerns about the lasting toll of traumatic brain injuries to US troops

The lasting effects of traumatic brain injuries on American troops are raising concerns amidst conflicts like the Iran war. Nearly 700 U.S. service members have been wounded by drone and missile attacks in the Middle East, many experiencing TBIs while returning to duty. Experts note that blast injuries are a different cellular injury than blunt trauma, and mild initial symptoms can sometimes lead to persistent issues such as headaches or difficulty with memory.
