According to the World Health Organization between 2015 and 2050, the percentage of people over 60 will almost double, highlighting that the population's aging pattern is much faster than in the past. Therefore, all countries face significant challenges to ensure that their health and social systems are prepared to face this demographic change. ​ This population aging trend increases the prevalence and incidence of health problems associated with age and the decline of different physiological systems, among which we can highlight those of a neurological nature such as dementia, Alzheimer's disease or in its earliest phase Mild cognitive impairment on the one hand, and those of a functional type such as frailty and physical condition on the other. The most direct consequence of the increase in the incidence of these diseases is the partial or total loss of the autonomy of the people that generates a high dependency index.
