A 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 leading to signs and/or symptoms that can be physical (e.g., headache, dizziness), cognitive (e.g., difficulty concentrating or remembering), emotional or behavioral (e..g., depression, irritability) or related to sleep (e.g., drowsiness, poor quality of sleep). A concussion is an injury that cannot be seen on x-rays, CT or MRI scans. A concussion should be suspected in any athlete who sustains a significant impact to the head, face, neck, or body and reports ANY symptoms or demonstrates ANY visual signs of a concussion. A concussion should also be suspected if an athlete reports ANY concussion symptoms to one of their peers, parents, teachers, or coaches or if anyone witnesses an athlete exhibiting ANY of the visual signs of concussion. Some athletes will develop symptoms immediately while others will develop delayed symptoms (beginning 24-48 hours after the injury).

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.
