Can Persons with Alzheimer’s Disease Express Their Aesthetic Preferences? Insights into the Design of Facilities

Background/Objectives: Facilities for persons with Alzheimer disease need to be adapted for them in terms of architecture and interior and exterior design, where the introduction of an artistic dimension is recommended. This raises the question of exploring the aesthetic preferences of the people concerned in order to optimise the design. We assessed whether individuals with Alzheimer’s disease can make aesthetic judgements, and if so, their nature and how stable they were over time. Methods: We compared the aesthetic preferences of 23 persons with Alzheimer’s disease matched to 23 controls. Preferences were collected using a Q-PEG questionnaire, which presents photographs of various artworks: paintings, sculptures, functional objects, and representation of living things: human, animal, and landscape, in various styles: figurative, stylized, abstract. This tool was created specifically by our team for this research; this is the first exploratory publication to use it. Results: We confirm the feasibility of collecting aesthetic judgements from individuals living with Alzheimer’s disease using the Q-PEG tool. The aesthetic judgements of both participant groups proved to be stable over time. Furthermore, the aesthetic judgements of individuals with Alzheimer’s disease did not differ from those of the controls, regardless of the style or type of artwork. These preferences are independent of the various cognitive functions assessed. Hypotheses about the Alzheimer-resistant nature of the cognitive register of aesthetic preferences are discussed. Conclusions: As they can express their artistic preferences, individuals living with Alzheimer’s disease should be consulted. These results provide insights for the design of facilities and therapeutic gardens based on evidence-based design (EBD) criteria. The integration of an artistic dimension in line with these preferences and in compliance with the general recommendations makes it possible to create adapted, specific spaces that are appreciated by all.
