What is TBI?

The VA defines Traumatic Brain Injury (TBI) as something that “happens when something outside the body hits the head with significant force” such as when “a head hits a windshield during a car accident,” “a piece of shrapnel enters the brain,” or during an explosion of an improvised explosive device (IED).” Individuals who sustain a TBI may experience a variety of effects, such as an inability to concentrate, an alteration of the senses (hearing, vision, smell, taste, and touch), difficulty speaking, and emotional and behavioral changes. Whether the TBI is mild, moderate, or severe, persistent symptoms can have a profound impact on the injured survivor and those who serve as caregivers.

According to the Defense and Veterans Brain Injury Center (DVBIC), more than 200,000 veterans who have served since 2000 have suffered from TBI, with more than 44,000 of those cases labeled moderate to severe.
