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's 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 a membership organisation, which works to improve the quality of life of people affected by dementia in England, Wales and Northern Ireland. Many of the 25,000 members have personal experience of dementia, as carers, health professionals or people with dementia themselves. 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. The Chief Executive of the Alzheimer's Society is Kate Lee, who replaced Jeremy Hughes on 2 March 2020. History The organisation was formed in 1979, when two people with extensive experience of caring for relatives with dementia discussed the pressing need to raise awareness of dementia and to improve the quality of care, support and information for people with dementia and their carers. This led to the creation of the Alzheimer's Disease Society. A steering committee was formed, consisting of carers and medical professionals, and the first annual general meeting was held on 13 September 1980. This first AGM was attended by 98 members and supporters. The first Newsletter was published in January 1981. A development officer was employed at around this time, and the first branches were established in Oxford and Bromley in 1980 and 1981 respectively. One of the Society's earliest contributions to research, as described in the Newsletter of January 1981, was a request for brain tissue donations to help support research studies. Through the 1980s and 1990s the society continued to grow, with volunteer committees establishing branches across England, Wales and Northern Ireland. At the AGM in 1999 members of the society agreed the change of name to Alzheimer's Society. By 2003 the Society had a turnover of £30 million, with over 230
