Symptoms revealed as "most problematic" varied by measurement criterion. Common or frequent symptoms are not necessarily the most distressing or most predictive of caregiver depression.

Closer relationships between caregivers and care recipients with dementia are associated with positive outcomes for care recipients, but it is unclear if closeness is a risk or protective factor for the health and psychological well-being of caregivers. We examined 234 care dyads from the population-based Cache County Dementia Progression Study. Caregivers included spouses (49%) and adult offspring (51%). Care recipients mostly had dementia of the Alzheimer’s type (62%). Linear mixed models tested associations between relationship closeness at baseline, or changes in closeness prior to versus after dementia onset, with baseline levels and changes over time in caregiver affect (Affect Balance Scale; ABS), depression (Beck Depression Inventory; BDI), and mental and physical health (components of the Short-Form Health Survey; SF-12). After controlling for demographic characteristics of the caregiver, number of caregiver health conditions, and characteristics of the care recipient (type of dementia, functional ability, and behavioral disturbances), we found that higher baseline closeness predicted higher baseline SF-12 mental health scores (better mental health), and lower depression. Higher baseline closeness also predicted greater worsening over time in ABS and SF-12 mental health. In addition, caregivers who reported a loss of closeness in their relationship with the care recipient from pre- to post-dementia displayed improved scores on ABS and SF-12 mental health, but worse SF-12 physical health over the course of the study. These results suggest that closeness and loss of closeness in the care dyad may be associated with both positive and adverse outcomes for caregivers, both cross-sectionally and over time.

Our findings are consistent with conceptual notions implicating disability-related factors as key contributors to late-life change and suggest that contextual and psychosocial factors play a pivotal role for how well people adapt to late-life challenges.

Objectives Late-life disability in Activities of Daily Living (ADL) is theorized to be driven by underlying cognitive and/or physical impairment, interacting with psychological and environmental factors. While we expect that cognitive deficits would explain associations between ADL disability and dementia risk, the current study examined ADL as a predictor of future dementia after controlling for global cognitive status. Methods The population-based Cache County Memory Study (CCMS; N=3547) assessed individuals in four triennial waves (average age 74.9, years of education 13.36; 57.9% were women). Cox proportional hazards regression models assessed whether baseline ADL disability (presence of 2+ Instrumental ADL and/or 1+ Personal ADL) predicted incident dementia after controlling for APOE status, gender, age, baseline cognitive ability (Modified Mini-mental State Exam, 3MS-R; adjusted for education level), and baseline depressive symptoms (Diagnostic Interview Schedule). Results Over the course of study, 571 cases of incident dementia were identified through in-depth cognitive assessment, ending in expert consensus diagnosis. Results from Cox models suggest that ADL disability is a statistically significant predictor of incident dementia (adjusted Hazard Ratio=1.83, p<.001), even after controlling for covariate. Conclusions Findings suggest that ADL disability offers unique contributions in risk for incident dementia, even after controlling for global cognitive status. We discuss how physical impairment and executive function may play important roles in this relationship, and how ADL is useful, not just a diagnostic tool at, or after dementia onset, but as a risk factor for future dementia, even in individuals not impaired on global cognitive tests.

Objectives Behavior problems that co-occur during assistance with Activities of Daily Living (Resistiveness to Care; RTC) are considered challenging, but are mostly studied in institutions with implications for patients and formal caregivers. RTC is related to, but independent from agitation, and detection of RTC may be left out of common assessments of persons with dementia in studies of informal caregiving (e.g. global assessments of dementia behavioral symptoms, standard assessments of ADL function). This study examines how RTC (frequency and caregivers’ stress appraisals of RTC) are related to caregivers’ well-being. Method 234 caregivers of people with dementia reported care receivers’ ADL impairment (eating, bathing, dressing), RTC frequency (of eating, bathing dressing), and their stress appraisals of these behaviors (RTC appraisals). Caregivers also self-reported their role overload, role captivity, and depressive symptoms. Hierarchical linear regression models included independent variables (demographics, ADL impairment, RTC frequency, RTC appraisals) with three separate dependent variables (overload, captivity, depressive symptoms). Results Two-thirds of informal caregivers reported RTC. Care recipients’ ADL impairment was associated with caregiver outcomes, but only before RTC was entered into the models. RTC frequency significantly predicted caregivers’ overload, captivity, and depression. RTC appraisals predicted overload and captivity. Conclusion RTC is common in persons with dementia residing at home, and RTC has more negative association with informal caregivers’ well-being than assistance with ADL. Adding RTC frequency and appraisal items to standard ADL measures may better estimate caregiver needs and risk, and identify modifiable environmental features by assessing behavioral symptoms in context.
