Abstract Recruiting and enrolling older adults with cognitive impairment is challenging under the best of circumstances. This symposium will begin with an introduction to best practices for recruitment of older adults living with cognitive impairment, followed by four presentations describing recruitment successes and challenges across multiple settings. The first presentation describes COVID-19 pandemic-related factors that have influenced recruitment and enrollment of older adults with cognitive impairment in an intervention study of a physical activity smartphone app. Strategies and procedural alterations to facilitate achievement of enrollment goals for technology-based interventions are discussed. The second presentation describes researchers’ recruiting experiences with older adults with mild cognitive impairment (oaMCI)-care partner dyads for a pilot, platform trial of biopsychosocial interventions. There were differences in study disinterest between oaMCI and study partners that may require specialized communication messaging and strategies for dyad engagement. The third presentation features recruitment adaptations for an Internet-delivered behavioral intervention study with oaMCI and insomnia. Anticipated concerns of oaMCI using technology or accessing the Internet were not significant barriers to recruitment, while fewer oaMCI endorsed sleep concerns than expected. The last presentation demonstrates the potential for telephone-based outreach to increase dementia knowledge and cognitive risk. Working with faith-based health educators to reach rural, ethnically-diverse older adults, researchers will describe how to promote inclusivity and successfully recruit oaMCI within the community. Presenters and participants are encouraged to dialogue on how recruitment and retention barriers may be avoided as well as to share success stories from their own research with oaMCI.

Across the breadth of acquired neurogenic communication disorders, mild cognitive impairment (MCI) may go undetected, underreported, and untreated. In addition to stigma and distrust of healthcare systems, other barriers contribute to decreased identification, healthcare access, and service utilization for Hispanic and African American adults with MCI. Speech-language pathologists (SLPs) have significant roles in prevention, education, management, and support of older adults, the population must susceptible to MCI.

Abstract Value-directed strategic processing is important for daily functioning. It allows selective processing of important information and inhibition of irrelevant information. This ability is relatively preserved in normal cognitive aging, but it is unclear if mild cognitive impairment (MCI) affects strategic processing and its underlying neurophysiological mechanisms. The current study examined behavioral and EEG spectral power differences between 16 cognitively normal older adults (CNOA; mean age: 74.5 ± 4.0 years) and 16 individuals with MCI (mean age: 77.1 ± 4.3 years) linked to a value-directed strategic processing task. The task used five unique word lists where words were assigned high- or low-value based on letter case and were presented sequentially while EEG was recorded. Participants were instructed to recall as many words as possible after each list to maximize their score. Results revealed no group differences in recall of low-value words, but individuals with MCI recalled significantly fewer high-value words and total number of words relative to CNOA. Group differences were observed in theta and alpha bands for low-value words, with greater synchronized theta power for CNOA than MCI and greater desynchronized alpha power for MCI than CNOA. Collectively, these findings demonstrate that more effortful neural processing of low-value words in the MCI group, relative to the CNOA group, allowed them to match their behavioral performance to the CNOA group. Individuals with MCI appear to utilize more cognitive resources to inhibit low-value information and might show memory-related benefits if taught strategies to focus on high-value information processing.

Community Dwelling Older Adults

This study examined the prevalence of cognitive impairment among older adults in central Vietnam and the roles of communication (with or without communication devices) in the association between cognitive impairment and hearing loss. This cross-sectional study was performed on 725 randomly selected community-dwelling older adults aged ≥60 years from Thua Thien Hue province, Vietnam. Participants attended a face-to-face survey. Sociodemographic characteristics, social interaction with or without communication devices, health status and cognitive function using the Mini-Mental State Examination were reported. Ordinal logistic regression analysis was performed to quantify the association between hearing loss and cognitive function by frequency of communication with and without devices. Mild and severe cognitive impairment had prevalence rates of 23.6% and 19.3%, respectively. Cognitive impairment was more prevalent among older adults with hearing-loss, vision loss and difficulties with instrumental activities of daily living (IADL). The association between hearing loss and cognitive impairment was not significant when older adults had frequent communication with others using devices. This study presented the relatively high prevalence of cognitive impairment in community-dwelling older adults in Vietnam. Frequent communication using devices attenuated the association between hearing loss and cognitive impairment.
