 U.S. Senator Kirsten Gillibrand of New York is co-sponsoring a bill to help military veterans with brain injuries caused by loud explosions. WSHU's Desiree Diorium explains. The weapons used by the military in combat and during training can cause traumatic brain injuries that contribute to headaches, hallucinations, and problems with cognition and mental health. Gillibrand says the bill would require the Defense Department to track, prevent, and treat these injuries.
