Abstract
This paper strives to place in context the circumstances of the elderly and elderly people with Alzheimer's, while also setting out the general characteristics they bear and detailing various research projects that seek to improve the wellbeing of these elderly persons. A review is conducted which reveals how technology can favour mood in old age, introducing different lines of research and innovative social projects, emphasising social intervention through artificial intelligence. The world and society are evolving on a daily basis; hence, intervention and the social field must adapt to these changes, innovating in the way we intervene with people, without overlooking the interventions and models that have led us to the present day.
