Alzheimer's Society

Alzheimer's Society is a United Kingdom care and research charity for people with dementia and their carers. It operates in England, Wales and Northern Ireland, while its sister charities Alzheimer Scotland and Alzheimer Society of Ireland cover Scotland and the Republic of Ireland respectively.

Despite its name, the charity does not exclusively help people with Alzheimer's disease. There are many types of dementia, which is an umbrella term. Dementia types include vascular dementia, dementia with Lewy bodies, frontotemporal dementia, Korsakoff's syndrome, Creutzfeldt–Jakob disease, HIV-related cognitive impairment, mild cognitive impairment, and other rarer causes of dementia.

It is an organisation that provides support for people affected by dementia via a telephone support line, as well as through dementia support workers, printed information and an online community called Talking Point.

Alzheimer's Society funds dementia research. In 2021/2022, £7m was given in 27 awards for new research, and 311 new publications came from their funding.

The society relies on voluntary donations from the public through fundraising and other activities. It is a registered Charity No. 296645, registered as a company limited by guarantee and registered in England No. 2115499. Its registered office is at 43-44 Crutched Friars, London, EC3N 2AE.

As of 2023 the Chief Executive of the Alzheimer's Society is Kate Lee, who replaced Jeremy Hughes on 2 March 2020.
