According to the Wounder Warrior's Website, "In addition to the physical wounds, it is estimated
as many as 400,000 service members live with the invisible wounds of war including combat-
related stress, major depression, and post-traumatic stress disorder. Another 320,000 are
believed to have experienced a traumatic brain injury while on deployment."
Definitions (By Mayo Clinic Staff)
PTSD- "Post-traumatic stress disorder is a mental health condition that's triggered by a terrifying event — either experiencing it or witnessing it. Symptoms may include flashbacks, nightmares and severe anxiety, as well as uncontrollable thoughts about the event."
TBI- Traumatic brain injury occurs when an external mechanical force causes brain dysfunction. Traumatic brain injury usually results from a violent blow or jolt to the head or body. An object penetrating the skull, such as a bullet or shattered piece of skull, can cause traumatic brain injury.
