The majority of people with Alzheimer's disease (AD) live at home with their spouses. AD erodes the ability of each member of the couple to support each other. Moreover, couples may be unaccustomed to seeking or accepting emotional and practical support from family members or formal resources. Even though AD can have a major negative impact on each member of the couple and on their relationship, their needs have generally been addressed separately, often without sufficient appreciation for the importance of their ongoing relationship. Previous studies suggest that by improving support for both members of the couple, the intervention will have a positive effect on mental health outcomes such as depression and help keep the person with AD at home rather than in a long-term care facility.
