About

Alzheimer's disease (AD) is increasing exponentially, with a projected quadrupling of cases by the mid 21st century. Individuals with AD are at increased risk for a host of medical and psychiatric conditions, and evidence is accumulating supporting the efficacy and effectiveness of psychosocial interventions for improving their mood, function, health, and quality of life. Such interventions are likely to be most effective when they are implemented during the early stages of dementia, when individuals and their family members are coping with the initial diagnosis and associated changes in abilities and activities. Recent randomized clinical trials by the Principal Investigator and colleagues have developed two non-pharmacologic interventions to reduce the social, psychological, physical, and behavioral impact of dementia. This investigation is focused on facilitating their translation into ongoing community-based programs, such as those provided by Alzheimer's Association chapters, senior centers, retirement homes, and other health care providers. The core content of each intervention has been retained in order to maintain or improve their efficacy, and each has been modified to a 4-week group format to increase efficiency of delivery. These modified interventions (ESML-Social and ESML-Ex) will be compared to each other and to a usual care (UC) control group. Outcomes will be assessed at baseline, 1-month post treatment, and 4 month follow-up. Primary outcomes at the 1-month assessment include: social activity participation, family communication, physical activity participation, and physical function. Primary outcomes at 4-month follow up include overall quality of life and depression. It is hypothesized that ESML-Ex and ESML-Social both will have greater improvements than UC. It is hypothesized that ESML-Social will have greater improvements in social participation and family communication than ESML-Ex and UC. It is hypothesized that ESML-Ex will have greater improvements in physical activity participation and physical functioning than ESML-Social and UC. If successful, these 4-week programs may be developed into "modules" that can be incorporated into programming for individuals with early stage dementia in a variety of community settings.

ESML-Exercise (Physical Activity Program)

Active Comparator group

Description:

ESML-Exercise consists of four weekly 90-minute classes. Each class includes exercises and a brief discussion of a specific health topic. Classes are carried out in small groups of five to six participant/care partner dyads (10-12 people total), to ensure everyone in the class gets individual attention and that all exercises are done safely using proper form.

Treatment:

Behavioral: ESML-EX (Physical Activity Program)

ESML-SOCIAL (Social Activity Program)

Active Comparator group

Description:

ESML-SOCIAL consists of four weekly 90-minute seminars. Each seminar includes discussion of a specific topic, open time for socializing, and a "homework" assignment to be completed prior to the next session. Seminars are carried out in small groups of five to six participant/care partner dyads (10-12 people total), to ensure everyone in the seminar gets individual attention and that everyone has a chance to bring up any concerns.

Treatment:

Behavioral: ESML-Social (Social Activity Program)

No Intervention

No Intervention group

Description:

This arm will receive no intervention during the active treatment period. After the 4 month assessment participants can choose to attend a support group.
