Quizplus · Accepted Answer

Traumatic brain injuries (TBIs) are considered the "signature injury" of recent wars, particularly in conflicts in Iraq and Afghanistan. The use of improvised explosive devices and other high-explosive weapons has resulted in an increased incidence of TBIs among service members. Symptoms of TBI can include memory problems, poor concentration, headaches, difficulty sleeping, and emotional instability. These symptoms can have long-term effects on a service member's quality of life and ability to function in daily life.
