A neurologist at Macquarie University is launching an awareness campaign called 'The Concussion Big 5', that aims to educate others about the dangerous signs of a concussion. 

Dr Rowena Mobbs told Mark Gibson on Perth Live that her work discovered how desperate parents are to understand concussions and how they can recognise them.

"We call concussions 'the big 5' so five 's', slump is the knock-out component, sway is appearing wobbly on your legs, slow is walking slowly or delayed in your movements, stun is appearing confused or behaving unusually and slur is slurred speech or poor response," Dr Mobbs explained.

Dr Mobbs has also called for footballers to be stood down for four weeks after suffering a concussion. 

"We would like to see a continued review of time away after a concussion. Four weeks is a conservative approach, it's longer than the 12 days we see but the brain is really precious and it's an important part of high performance sport so we think it can actually benefit the sport and the players."
