Concussion

Concussion Overview

Patient Comments

The term concussion describes an injury to the brain resulting from an impact to the head. By definition, a concussion is not a life-threatening injury, but it can cause both short-term and long-term problems. A concussion results from a closed-head type of injury and does not include injuries in which there is bleeding under the skull or into the brain. Another type of brain injury must be present if bleeding is visible on a CT scan (CAT scan) of the brain.

  • A mild concussion may involve no loss of consciousness (feeling "dazed") or a very brief loss of consciousness (being "knocked out").
  • A severe concussion may involve prolonged loss of consciousness with a delayed return to normal.
