Alzheimer's disease (AD) is a threat to the individual and marital integrity of couples as the relationship is called upon to evolve into a caregiver-patient one. In Quebec (Canada), there are currently very few services offered in which these couples can participate together as a couple. In a qualitative multi-case study, five couples had the opportunity to participate in art therapy informed by integrative behavioral couple therapy over 10 meetings held in their homes. The results suggest that art therapy has many positive benefits on these couples, such as providing pleasure, expressing emotions, assessing relational dynamics, and fostering empathy. It was found that art therapy fulfilled five specific functions: play, appease, stimulate, express, and transform.
