(Reuters) - Former Manchester United manager Alex Ferguson has said it is his personal duty and the game's responsibility to address the problem of dementia that has impacted several former players.

The issue of dementia in the professional game was sparked by the death of England's Nobby Stiles in October and there have been calls for the issue of head injuries in sport to be given further attention.
