When a bump, jolt, or blow to the head causes a change in the way the brain works, it is called a concussion. A concussion is a type of traumatic brain injury (TBI) that causes the brain to move quickly back and forth inside the skull. They are sometimes considered “mild” because concussions are not typically life-threatening. Concussions are characterized by:

  • An episode of observed or self-reported transient confusion, disorientation, or impaired consciousness;
  • An episode of observed or self-reported dysfunction of memory around the time of injury;
  • Observed signs of neurological dysfunction acutely following the injury, such as:
    • Seizures;
    • Irritability, lethargy, or vomiting;
    • Headache, dizziness, fatigue
    • Poor concentration
  • Any period of observed or self-reported loss of consciousness lasting 30 minutes or less.

A person can suffer a concussion without having a loss of consciousness (LOC). The key point to remember is that concussions are defined by altered consciousness, the presence of which is evidence of brain injury.
