There is a potential link between mental illness and concussion, although the relationship is not clear. Athletes with a history of mental illness require a more cautious approach. A conservative Return to Sport strategy is recommended.

There are a number of organisations with information on mental illness and where to go for help:

• Lifeline provides a 24 hour, 365 days per year crisis support and suicide prevention service. It is free and provides immediate support for those in need.
• Headspace is a national youth mental health support service providing mental health assistance to those aged 12–25.
• Beyond Blue supports Australians to protect their mental health through education and awareness.
