Evaluation of a care management program on family caregivers of persons with dementia.

As the U.S. population ages, dementia due to Alzheimer's or other disease is concerning for healthcare providers. Family caregivers (FCGs) of persons with dementia (PWDs) may experience negative outcomes. The University of California, Davis, Health (UCDH) Alzheimer's and Dementia Care (ADC) Program provides care management for PWDs and their FCGs. This pilot study evaluates the program's effect on FCG depression, strain, and distress. Despite an increase in dementia severity in PWDs, FCGs experienced decreased levels of depression, strain, and distress following 12 to 18 months in the UCDH ADC Program. Other findings include PWDs experiencing reductions in severity of neuropsychiatric symptoms and remaining at home with FCGs. Despite limitations, such as a relatively small sample size and lack of sample diversity, this pilot study demonstrated positive outcomes to both PWDs and their FCGs and contributes to the literature supporting dementia care management programs. Future projects should address these limitations to understand the experiences of a diverse population and to make dementia care management programs sustainable.

Assessing Dementia Prevalence in the Wisconsin Longitudinal Study: Cohort Profile, Protocol, and Preliminary Findings.

BACKGROUND: There is growing consensus that non-genetic determinants of dementia can be linked to various risk- and resiliency-enhancing factors accumulating throughout the lifespan, including socioeconomic conditions, early life experiences, educational attainment, lifestyle behaviors, and physical/mental health. Yet, the causal impact of these diverse factors on dementia risk remain poorly understood due to few longitudinal studies prospectively characterizing these influences across the lifespan. OBJECTIVE: The Initial Lifespan's Impact on Alzheimer's Disease and Related Dementia (ILIAD) study aims to characterize dementia prevalence in the Wisconsin Longitudinal Study (WLS), a 60-year longitudinal study documenting life course trajectories of educational, family, occupational, psychological, cognitive, and health measures. METHODS: Participants are surveyed using the modified Telephone Interview for Cognitive Status (TICS-m) to identify dementia risk. Those scoring below cutoff undergo home-based neuropsychological, physical/neurological, and functional assessments. Dementia diagnosis is determined by consensus panel and merged with existing WLS data for combined analysis. RESULTS: Preliminary findings demonstrate the initial success of the ILIAD protocol in detecting dementia prevalence in the WLS. Increasing age, hearing issues, lower IQ, male sex, APOE4 positivity, and a steeper annualized rate of memory decline assessed in the prior two study waves, all increased likelihood of falling below the TICS-m cutoff for dementia risk. TICS-m scores significantly correlated with standard neuropsychological performance and functional outcomes. CONCLUSION: We provide an overview of the WLS study, describe existing key lifespan variables relevant to studies of dementia and cognitive aging, detail the current WLS-ILIAD study protocol, and provide a first glimpse of preliminary study findings.
