There are numerous adverse health outcomes associated with dementia caregiving, including increased stress and depression. Caregivers often face time-related, socioeconomic, geographic, and pandemic-related barriers to treatment. Thus, implementing mobile health (mHealth) interventions is one way of increasing caregivers’ access to supportive care. The objective of the current study was to collect data from a 3-month feasibility trial of a multicomponent mHealth intervention for dementia caregivers.

40 community-dwelling dementia caregivers were randomized to receive the CARE-Well (Caregiver Assessment, Resources, and Education) App or internet links connected to caregiver education, support, and resources. Caregivers were encouraged to use the App or links at least 4 times per week for 3 months. The App consisted of self-assessments, caregiver and stress reduction education, behavior problem management, calendar reminders, and online social support. Caregivers completed measures of burden, depression, and desire to institutionalize at baseline and post-intervention. Feasibility data included App usage, retention and adherence rates, and treatment satisfaction. Data were analyzed via descriptive statistics.

Caregivers were mostly white (95%), female (68%), in their mid-60s, (M= 66.38, SD= 10.64), and well-educated (M= 15.52 years, SD= 2.26). Caregivers were mainly spouses (68%) or adult children (30%). Care recipients were diagnosed with mild (60%) or moderate (40%) dementia, with 80% diagnosed as having Alzheimer’s disease. Overall, the study had an 85% retention rate (80% for App group; 90% for links group). 58% of caregivers in the App group were considered high users, using the App >120 minutes over the course of 3 months (M= 362.42, SD= 432.68), and an average of 16.44 days (SD= 15.51). 15% of the sample was non-adherent due to time constraints, disinterest, and/or technology issues. Most participants (75%) using the App were mostly or very satisfied, about 87% would be likely or very likely to seek similar programs in the future, and 93% found the App mostly or very understandable. Groups did not significantly differ on clinical outcomes, although the study was not powered for an efficacy analysis. Within groups analysis revealed significant increases in depressive symptoms at post-treatment for caregivers in both groups.

This study demonstrated initial feasibility of the CARE-Well App for dementia caregivers. App use was lower than expected, however, high satisfaction, ease of use, and willingness to use similar programs in the future were endorsed. Some caregivers did not complete the intervention due to caregiving responsibilities, general disinterest, and/or technology issues. Although the study was not designed to assess clinical outcomes, we found that both groups reported higher depressive symptoms at post-treatment. This finding was unexpected and might reflect pandemic-related stress, which has been shown to particularly impact dementia caregivers. Future studies should address the efficacy of multicomponent mHealth interventions for dementia caregivers and the effects of increased dose on clinical outcomes. mHealth interventions should be refined to cater to varying levels of technology literacy among caregivers, and further research should aim to better integrate interventions into caregivers’ routines to enhance treatment engagement.

Mild cognitive impairment (MCI) is an etiologically nonspecific diagnosis including a broad spectrum of cognitive decline between normal aging and dementia. Several large-scale cohort studies have found sex effects on neuropsychological test performance in MCI. The primary aim of the current project was to examine sex differences in neuropsychological profiles in a clinically diagnosed MCI sample using clinical and research diagnostic criteria.

The current study includes archival data from 349 patients (age M = 74.7; SD = 7.7) who underwent an outpatient neuropsychological evaluation and were diagnosed with MCI. Raw scores were converted to z-scores using normative datasets. Sex differences in neurocognitive profiles including severity, domain-specific composites (memory, executive functioning/information processing speed, and language), and modality-specific learning curves (verbal, visual) were examined using Analysis of Variance, Chi-square analyses, and linear mixed models. Post hoc analyses examined whether sex effects were uniform across age and education brackets.

Females exhibit worse non-memory domain and test-specific cognitive performances compared to males with otherwise comparable categorical MCI criteria and global cognition measured via screening and composite scores. Analysis of learning curves showed additional sex-specific advantages (visual Males>Females; verbal Females >Males) not captured by MCI subtypes.

Our results highlight sex differences in a clinical sample with MCI. The emphasis of verbal memory in the diagnosis of MCI may result in diagnosis at more advanced stages for females. Additional investigation is needed to determine whether these profiles confer greater risk for progressing to dementia or are confounded by other factors (e.g., delayed referral, medical comorbidities).

Older adults referred for cognitive concerns, 87 of whom were cognitively intact (CI) and 206 of whom were diagnosed with MCI.

The MMSE, the 3MS, and comprehensive neuropsychological evaluations.

Both instruments were significant predictors of diagnostic outcome (CI or MCI), with comparable odds ratios, but the 3MS explained more variance and showed improved classification accuracies relative to the MMSE. The 3MS also demonstrated greater receiver operating characteristic area under the curve values (0.85, SE = 0.02) compared to the MMSE (0.74, SE = 0.03). Scoring lower than 95/100 on the 3MS suggested MCI, while scoring lower than 28/30 on the MMSE suggested MCI. Additionally, compared to the MMSE, the 3MS shared more variance with neuropsychological composite scores in Language and Memory domains but not in Attention, Visuospatial, and Executive domains. Finally, 65.5% MCI patients were classified as impaired (scoring ≤1 SD below the mean) using 3MS normative data, compared to only 11.7% of patients who were classified as impaired using MMSE normative data.

Broadly speaking, our data strongly favor the widespread substitution of the MMSE with the 3MS in older adults with concerns for cognitive decline.

We assessed the ability of a telephone-administered cognitive screening test – Minnesota Cognitive Acuity Screen (MCAS) – to predict time to assisted living/nursing home placement (i.e. institutionalization) and homecare/institutionalization in healthy controls (HC), mild cognitive impairment (MCI), and Alzheimer's disease (AD).

Participants (N = 146; HC = 37; MCI = 70; AD = 39) had baseline MCAS testing and were re-contacted over eight years for dates of starting homecare, institutionalization, and death. Occasionally, outcomes were obtained via medical records. Accounting for informative censoring due to death within a competing risks framework, Cox regression examined the associations of baseline MCAS performance with the start of (a) institutionalization and (b) homecare/institutionalization.

Hazard ratios (HR) captured the effect of a ten-point difference in baseline MCAS scores, corresponding to a change from the MCI/HC to AD/MCI boundaries. In unadjusted models, increased baseline cognitive impairment was associated with nearly two-fold increases in the hazard of institutionalization (HR = 1.81, 95% CI = 1.32, 2.48) and homecare/institutionalization (HR = 1.87, 95% CI = 1.44, 2.42). However, hazards were not proportional over time in models adjusting for sex. This was resolved when regressions were run for men and women separately. Both sexes showed significant increases in the hazard of institutionalization (Females: HR = 2.39, 95% CI = 1.53–3.74; Males: HR = 1.68, 95% CI = 1.02–2.76) and homecare/institutionalization (Females: HR = 2.31, 95% CI = 1.66, 3.21; Males: HR = 1.98, 95% CI = 1.32, 2.96) with increased impairment, although hazards were lower for males.

Telephone-administered MCAS provides useful information about the risk of needing homecare assistance or institutionalization. It may be particularly useful when office/home visits are prohibitive but cognitive monitoring is indicated.
