Former West Bromich Albion Striker Jeff Astle died at the age of 59 in 2002, and Jeff Astle's daughter Dawn Astle, is trying to find the link between repetitive blows to the head from headering the ball to Alzheimer's or dementia type symptoms.
So does headering the ball repetitively cause Brian Damage ???
