Should we move in with Mom, or move her in with us?

Whether to move in with an Alzheimer parent or move them to a family member's home is a frequently asked and quite realistic question. I do feel that your concern about the possible exacerbation of the disease in an unfamiliar setting is legitimate and should be a concern. It is wonderful that someone in your family is stepping up to the plate with willingness to change their lifestlye by having your mom move in. But this does need to be about mom and the best venue for her to feel successful and secure. The ideal way to foster that goal is to keep her in the most familiar setting surrounded by well-known furnishings and peaceful remembrances. That would be her home where she will have less frustration and memories enhanced by the familar objects, colors, and design. Empirical data has certainly shown that any traumatic event or change in living situation or familial status does effect the rate of decline. You can optimize life in her home by slowly simplifying her environment; downsize by getting rid of extra clothing, papers, housewares etc making it as easy as possible for mom to function as normally as possible. Do not make changes suddenly and do keep her most treasured items nearby so she can feel comforted by their view. If you are making the move into mom's home, be sure to take time for you and take good care of yourself - her carepartner.
