The severity of a traumatic brain injury can range from a mild concussion to a severe injury resulting in coma or even death.

Traumatic brain injury can result from falls, violence, vehicle collisions, sports injuries and explosions. Traumatic brain injury symptoms may include loss of consciousness, memory or concentration problems, headaches, dizziness, nausea or vomiting, sensitivity to light or sound, mood changes and fatigue.
