Cognitive stimulation and activities of daily living for individuals with mild-to-moderate dementia: A scoping review

Introduction: Dementia is a progressive syndrome that interferes with the individual's ability to perform activities of daily living (ADL). Cognitive stimulation (CS) is a non-pharmacological approach aimed to mitigate the impact of dementia symptoms. While CS has been shown to provide benefits for cognition and quality of life, the evidence supporting its use in improving ADL outcomes is reduced. The aim of this review was to chart what is known from the literature about the use of CS in improving ADL outcomes. Method: A scoping review of the use of CS in improving ADL outcomes for individuals with mild-to-moderate dementia was conducted, following a scoping review methodological framework. Eight databases were searched, including all articles published up until June 2022. Findings: A three-step search strategy yielded 788 results. Following screening and review, 36 papers met the inclusion criteria for this review. Studies were charted and discussed in the areas of (1) cognitive stimulation therapy; (2) group CS programmes; (3) multi-component CS interventions; (4) individual CS programmes and (5) other types of CS. Conclusion: The review identified a range of CS programmes from across 13 countries worldwide. Multi-component CS interventions involving ADL-focused activities reported the most benefits for ADL outcomes.
