WHAT IS A CONCUSSION?

A brain injury caused by a blow to the head or a violent shaking of head and/or body that forces the brain to move in the skull. Due to this trauma, brain tissue can be stretched or damaged which will trigger harmful changes that interfere with normal brain activity.

There are three grades of severity

  • Grade I: no loss of consciousness and the injured experiences NO amnesia or amnesia is present for less than 30 minutes

  • Grade II: loss of consciousness for less than five minutes or the injured experiences amnesia for between 30 minutes and 24 hours

  • Grade III: loss of consciousness for more than five minutes or amnesia for more than 24 hours
