This multicentre study, employing a randomised controlled repeated measures experimental design, will be conducted in several Portuguese institutions that provide care and support services for older adults diagnosed with mild to moderate Alzheimer's disease (AD). The primary aim is to evaluate the effects of two distinct cognitive stimulation modalities (digital vs physical/analogue). The study will assess the impact of individual cognitive stimulation on multiple domains - specifically cognitive function (with an emphasis on memory and executive function), mood, and quality of life - and investigate how institutional and territorial characteristics influence these effects, considering geographical and organisational diversity as potential moderating factors.
