Overcoming Barriers to Latino Participation in Alzheimer's Disease Research.

There is a critical need to increase Latino participation in research on Alzheimer's disease and related disorders (ADRD). Applying principles of community-based participatory research, we convened a community advisory board (CAB) to identify barriers and recommend strategies to increase participation of older Latinos in a longitudinal observational research study of ADRD at the Shiley-Marcos Alzheimer's Disease Research Center. Six major barriers were identified and programmatic changes to overcome them were implemented. Changes resulted in a nearly three-fold increase in the number of Latino individuals recruited, with the proportion of all newly recruited participants who were Latino increasing from 12.2% to 57.4%. Newer Latino recruits were more representative of the elderly Latino population in San Diego County than those recruited pre-CAB and remained highly agreeable to blood draw and neuroimaging, though less so to lumbar puncture and autopsy. Results demonstrate the value of CAB involvement in enhancing diversity in ADRD research.

Comparison of the telephone-Montreal Cognitive Assessment (T-MoCA) and Telephone Interview for Cognitive Status (TICS) as screening tests for early Alzheimer's disease.

INTRODUCTION: Remote screening for cognitive impairment associated with Alzheimer's disease (AD) has grown in importance with the expected rise in prevalence of AD in an aging population and with new potential treatment options. METHODS: The Telephone Interview for Cognitive Status (TICS) and new telephone adaptation of the Montreal Cognitive Assessment (T-MoCA) were administered to participants independently classified through in-person clinical evaluation as cognitively normal (CN; n = 167), mild cognitive impairment (MCI; n = 25), or dementia (n = 23). Cerebrospinal fluid AD biomarkers were measured (n = 79). RESULTS: TICS and T-MoCA were highly correlated (r = 0.787; P < 0.001): groups differed on both (CN

A survey of smartphone and interactive video technology use by participants in Alzheimer's disease research: Implications for remote cognitive assessment.

INTRODUCTION: Participants from a longitudinal cohort study were surveyed to evaluate the practical feasibility of remote cognitive assessment. METHODS: All active participants/informants at the University of California San Diego Alzheimer's Disease Research Center were invited to complete a nine-question survey assessing technology access/use and willingness to do cognitive testing remotely. RESULTS: Three hundred sixty-nine of 450 potential participants/informants (82%) completed the survey. Overall, internet access (88%), device ownership (77%), and willingness to do cognitive testing remotely (72%) were high. Device access was higher among those with normal cognition (85%) or cognitive impairment (85%) than those with dementia (52%), as was willingness to do remote cognitive testing (84%, 74%, 39%, respectively). Latinos were less likely than non-Latinos to have internet or device access but were comparable in willingness to do remote testing. DISCUSSION: Remote cognitive assessment using interactive video technology is a practicable option for nondemented participants in longitudinal studies; however, additional resources will be required to ensure representative participation of Latinos.

Community memory screening as a strategy for recruiting older adults into Alzheimer's disease research.

BACKGROUND: Growing awareness of Alzheimer's disease (AD) has prompted a demand for quick and effective ways to screen for memory loss and cognitive decline in large numbers of individuals in the community. Periodic Memory Screening Day events provide free, brief cognitive screening aimed at those 65 years and older, and can serve as an opportunity to gauge participants' attitudes towards AD research and recruit them into ongoing research projects. METHODS: Over 6 single-day events in 2 years, more than 574 individuals were individually screened using the MoCA and a story recall task (immediate and delayed), given feedback about their performance, and introduced to AD research and opportunities to participate. RESULTS: Screening classified 297 individuals (52.0%) as having "No Decline," 192 (33.6%) as "Possible decline," and 82 (14.4%) as "Likely decline." Those with "Likely decline" were older and less educated, had more memory concerns, were more likely to be men, and were less likely to have a positive family history of dementia than those with "No Decline." Subsequent validation of screening procedures against a full clinical evaluation showed 72% classification accuracy with a skew towards over-calling Possible and Likely decline and thereby guiding questionable individuals to a more thorough evaluation. Of those screened, 378 (66%) agreed to additional research and consented to being listed in a research registry, and a majority (70-85%) of those consenting reported they were amenable to various AD research procedures including lumbar puncture, MRI, and autopsy. Overall, 19.1% of those screened met inclusion criteria for ongoing studies and were successfully recruited into AD research. CONCLUSIONS: Conducting a few concentrated community memory screening events each year may help meet the public's demand for brief assessment of memory concerns and can be a relatively effective and efficient recruitment strategy for AD research.

Grief experiences of 3 caregiving wives of veterans with dementia.

Three wives share their experiences of caregiving for husbands with dementia. The 3 husbands, aged 51, 71, and 84, developed dementia following years of devoted military service. To present lived experiences of caregiving wives', meanings attributed to caregiving are investigated, variations in caregiving and grieving experiences are explored, and therapeutic implications are offered. Through case study approach and with issues of caregiver grief considered, we introduce life course and ambiguous loss theoretical perspectives. Emergent qualitative themes and quantitative inventory ratings indicate significant differences in caregiver grief response depend on care-recipient age. Practice implications and directions for future care recipient, age-related research are presented.

Comparing responses to horticultural-based and traditional activities in dementia care programs.

Engaging persons with dementia in meaningful activities supports well-being; however, care staff are challenged to implement age- and ability-appropriate activities in a group setting. We compared a randomly assigned treatment group, who received horticultural therapy-based (HT-based) programming to a comparison group, who engaged in traditional activities (TA) programming, on engagement and affect. Horticultural therapy-based programming was implemented twice weekly at 4 treatment sites for 6 weeks, while regular TA were observed at comparison sites. Results revealed no differences between groups on affective domains. Levels of adaptive behavior differed between the groups, with the treatment group demonstrating higher levels of active, passive, and other engagement and the comparison group demonstrating higher levels of self-engagement. Our results highlight the value of HT-based programs and the importance of simultaneously capturing participants' affective and behavioral responses. Theoretical and practical considerations about the facilitation of and context in which the programming occurs are discussed.

Older women's experiences with multiple health conditions: daily challenges and care practices.

Guided by life-course theory and a trajectory model of chronic illness, we examined the health care practices and management strategies used by 17 older women with multiple chronic conditions. Qualitative analyses revealed that the women played an active role in shaping the course of their illness within their everyday lives. Pain and a decline in energy frequently interfered with completion of daily activities. To compensate, many women reduced and slowed down the pace of activities they performed while emphasizing the importance of maintaining independence and autonomy. Appreciative of support from family members, at times the women received more help and advice than they preferred.
