Concussion

A concussion is caused by a blow or jolt to the neck or head that shakes the brain. It often results in a temporary loss of consciousness that can be brief or prolonged. Symptoms may persist after the concussion. These symptoms vary in severity.

Things to consider

  • Severity
  • Amount of time spent unconscious
  • Number of concussions
  • Long-term neurological complications
  • Occupation
  • Participation in high-risk sports
