Around 225,000 people develop dementia every year, that's the equivalent to one person every three minutes. This September and October Memory Walks will be taking place across England, Wales and Northern Ireland to raise money for a world without dementia. Once you donate, JustGiving will send your money directly to Alzheimer's Society. So it's the most efficient way to raise money, saving time and cutting costs for the charity. Let's take on dementia together!
