Alzheimer's Society is a membership organisation, which works to improve the quality of life of people affected by dementia in England, Wales and Northern Ireland.
Many of our 20,000 members have personal experience of dementia, as carers, health professionals or people with dementia themselves, and their experiences help to inform our work.

Alzheimer's Society staff and volunteers provide both local information and over 2,000 services across England, Wales and Northern Ireland to people affected by dementia in their communities.
