The English Football Association has urged FIFA to investigate whether former players have dementia as a consequence of brain damage from playing the game. Three members of England's 1966 World Cup squad have Alzheimer's, family members said. Concerns have grown in Britain about the impact of head injuries after campaigning by the family of former England striker Jeff Astle. Jeff's death in 2002 was attributed to repeatedly heading heavy, leather balls. English Football Association medical head, Ian Beasley, is seeking assistance from world soccer's governing body to help determine if there are definitive long-term health dangers from playing the game, and if prospective players should be warned.
