CONCUSSION is a type of traumatic brain injury caused by a bump, blow or jolt to the head, face, neck or body that causes the head and brain to move rapidly back and forth and can alter the way the brain normally functions.

Example of some Signs & Symptoms

  • Physical (e.g., headache, dizziness),
  • Cognitive (e.g., difficulty concentrating or remembering),
  • Emotional/behavioral (e.g., depression, irritability), or
  • Related to sleep (e.g., drowsiness, poor quality of sleep)

Some athletes will develop symptoms immediately while others will develop delayed symptoms (beginning 24-48 hours after the injury). For a complete list of signs and symptoms please refer to the documents below.

A concussion should be suspected in any athlete who:

  • Sustains a significant impact to the head, face, neck, or body
  • Reports ANY symptoms of a concussion
  • Demonstrates ANY visual signs of a concussion

Or if anyone witnesses an athlete exhibiting ANY of the visual signs of concussion.

The CONCUSSION REPORTING FORM was developed to help Judo Canada monitor the occurrence of concussions during judo related activities (competition or training). This On-line form should be completed and submitted any time a concussion is suspected following an incident which occurred during a judo related activity.
