These guidelines are intended to provide information on how to recognise concussion and manage concussion from the time of injury through to a safe return to education, work and playing sport. This information is intended for the general public, and for individuals participating in underage and community sports.

The purpose of this inquiry was to explore the current evidence and challenges regarding contact sport-related concussion and repeated head injuries, and consider measures to improve the identification and prevention of these injuries, as well as reduce their short and long-term impacts.

This study presents the first evidence of altered brain structure and function at the time of medical clearance to return-to-play (RTP), with greater changes in brain function for athletes with a longer recovery time.

With the evidence mounting that concussion is linked to long term brain injuries, contact sports right around the world are on watch. However, the AFL's expert concussion group has consistently attacked the growing evidence, accusing scientists of dodgy research and fear mongering.
