Alzheimer's disease (AD) is a one of the leading cause of dependency among older adults and of institutionalization in Europe. The number of people with AD is estimated in 10 million people and the cost of the disease has been recently estimated in 100.000 million of euros per year in the European Union (European Brain Council, 2011). There is nowadays no effective treatment of the disease. Currently, care of AD patients is primary sustained by informal caregivers who suffer burden as a result of their care responsibilities, and consequently are mainly affected by mental health problems (depression, anxiety, etc). This burden is also related with a premature institutionalization and violence against AD patients. In this sense, effective solutions are needed in order to fight against the mental health problems of informal caregivers. Regarding this, a social innovation research, funded by the Progress Programme of the DG of Employment, Social Affairs and Inclusion of the European Commission, is being developed currently in France and Spain, where the authors are aimed to demonstrate how a specialized formal training in AD addressed to people in risk of labour and social exclusion could improve the quality of life of AD patients and reduce the informal caregiver burden. The results of this research is specially relevant to help to reduce mental health problems of the informal carers of AD patients, but also in terms of intervene on the cognitive skills of the persons affected, as well as to allow the employment of socially excluded people.
