In this video segment adapted from NOVA scienceNOW, learn about concussions—a common type of traumatic brain injury. Hear from Reed Snyderman, a young athlete who describes his personal experience with concussion. In addition, meet Dr. Jam Ghajar, a neurosurgeon and international expert in brain injuries, who explains why concussions are difficult to diagnose and demonstrates a new tool that can help assess brain injury. The portable tool measures disruptions in attention by tracking eye movements and offers a way to quickly and objectively diagnose concussions, even at a sporting event.
