Around 225,000 people develop dementia every year, that's the equivalent to one person every three minutes.  Dementia affected my lovely Nanny who was the most loving, generous and caring person, so this October I am walking a half marathon in her memory to raise money for a world without dementia. Once you donate, JustGiving will send your money directly to Alzheimer's Society.  Please dig deep and help me walk for a world without dementia - thank you X
