Head Injury & Concussion
As described by the Centers for Disease Control and Prevention (CDC), a concussion (also called mild traumatic brain injury, MTBI) is caused by a blow, blast, or jolt to either the head or the body that causes the brain to move rapidly inside the skull. A concussion can disrupt normal brain function and can have serious, long-term health effects. Symptoms of concussion include headache, nausea, fatigue, confusion or memory problems, sleep disturbances, or mood changes. Symptoms can be noticed right after the injury, but some might not be recognized until days or weeks later.
Sports and recreation, as well as military combat, are contexts in which concussions (MTBI) are prevalent.
