THE AFL's screening for concussion must become more rigorous, according to a medical expert.

The associate director of rehabilitation at Epworth Hospital, Professor John Olver, says evidence of potential brain damage is becoming more widespread as screenings improve.

"When I talk about more rigorous testing I'm talking about a full neuro-psychological evaluation, which provides more definitive answers than the current boundary line test,'' he said.

"What does `being checked out thoroughly' actually mean? If someone has had a number of concussions and you are worried about on-going thinking problems then you would do a full test.`

"Yes, it takes time, two to three hours from a trained psychologist, but there is mounting evidence to suggest we should be screening more vigorously.

"Certainly there is evidence, mainly from the US, that some of these guys suffering what they call multiple concussions suddenly find they they have long-term problems in slowness of thinking, irritability, and problem solving.

That would indicate more permanent damage than concussion would usually indicate.'

'Prof Olver believes the sports medicine and club doctors are not in agreement about the effectiveness of screening.

"We don't know a lot, though. For instance, should you wear a helmet after a concussive injury?

"One line of thinking suggests the helmet will help defuse the next shockwave to the brain and absorb the shock.

"The other train of thought suggests if you wear a helmet then the whole momentum of the head is greater, making it worse when you strike it on the ground.

"The important part is what happens after 24 hours because whether the symptoms persist defines the severity.

"The `manly' thing used to be you would just shrug it off.

"But putting a player back on ... after a first concussion is fraught with danger as it would seem the brain is more vulnerable if you go back on."
