RESUMEN

Objective: Older adults often spontaneously engage in compensatory strategies (CS) to support everyday task completion, but factors that influence success of chosen CS remain unclear. This study examines whether real-world prospective memory (PM) task completion is better predicted by CS count or a CS quality rating. Method: Seventy mid-life and older adult participants were presented four novel, real-world PM tasks via remote assessment and encouraged to use their typical CS. The examiner captured detailed information about planned CS at task presentation (T1) and utilized CS at follow-up testing (T2). From this information, count (CS Count; quantity of CS) and quality (CS Quality; rating of CS thoroughness and utility) scores were coded separately for the planned and utilized CS. PM task performance accuracy was also coded (PM Accuracy). Results: Hierarchical regressions revealed planned CS Count and Quality did not predict PM Accuracy. In contrast, the utilized CS Quality predicted a significant amount of PM Accuracy variance over and above CS Count, global cognition, and age (R2 = .47, ΔR2 = .24, ΔF = 29.36, p < .001, f2 = .45). Furthermore, utilized CS Quality accounted for a similar amount of variance in PM Accuracy when utilized CS Count was removed from the model. Conclusions: This study's CS coding system can capture and quantify the quality of strategies, which uniquely predicts real-world PM performance. This coding system may provide researchers with a nuanced CS measure and lead to improved CS interventions designed to support everyday PM performance, such as targeted CS trainings.

RESUMEN

BACKGROUND: Compensatory aids can help mitigate the impact of progressive cognitive impairment on daily living. OBJECTIVE: We evaluate whether the learning and sustained use of an Electronic Memory and Management Aid (EMMA) application can be augmented through a partnership with real-time, activity-aware transition-based prompting delivered by a smart home. METHODS: Thirty-two adults who met criteria for amnestic mild cognitive impairment (aMCI) were randomized to learn to use the EMMA app on its own (N = 17) or when partnered with smart home prompting (N = 15). The four-week, five-session manualized EMMA training was conducted individually in participant homes by trained clinicians. Monthly questionnaires were completed by phone with trained personnel blind to study hypotheses. EMMA data metrics were collected continuously for four months. For the partnered condition, activity-aware prompting was on during training and post-training months 1 and 3, and off during post-training month 2. RESULTS: The analyzed aMCI sample included 15 EMMA-only and 14 partnered. Compared to the EMMA-only condition, by week four of training, participants in the partnered condition were engaging with EMMA more times daily and using more basic and advanced features. These advantages were maintained throughout the post-training phase with less loss of EMMA app use over time. There was little differential impact of the intervention on self-report primary (everyday functioning, quality of life) and secondary (coping, satisfaction with life) outcomes. CONCLUSION: Activity-aware prompting technology enhanced acquisition, habit formation and long-term use of a digital device by individuals with aMCI. (ClinicalTrials.gov NCT03453554).

RESUMEN

OBJECTIVE: Individuals with Parkinson's disease (PD) are at risk for increased medication mismanagement, which can lead to worse clinical outcomes. However, the nature of the errors (i.e., undertaking or overtaking medications) contributing to mismanagement and their relationship to cognition in PD is unknown. Therefore, this study sought to examine errors committed on the Medication Management Ability Assessment (MMAA) between PD participants with normal cognition (PD-NC) or mild cognitive impairment (PD-MCI) relative to healthy adults (HA). METHOD: HA (n = 74), PD-NC (n = 102), and PD-MCI (n = 45) participants were administered the MMAA to assess undertaking, overtaking, and overall errors as well as overall performance (total score). Additionally, participants were administered a comprehensive neuropsychological battery from which cognitive composites of Attention, Learning, Memory, Language, Visuospatial, and Executive Functioning were derived. RESULTS: Separate negative binomial regression analyses indicated the PD-MCI group performed significantly worse overall on the MMAA (total score) and committed more undertaking and overall errors relative to HA and PD-NC. In the PD-MCI group, poorer MMAA performance was associated with worse delayed memory performance, whereas cognitive performance was not related to MMAA in HA or PC-NC. CONCLUSION: Compared to PD and healthy adults with normal cognition, PD-MCI patients exhibited greater difficulty with medication management, particularly with undertaking medications. Poorer medication management in PD-MCI was associated with worse delayed recall. Thus, PD-MCI patients experiencing memory problems may require additional assistance with their medications. Findings have clinical relevance suggesting that objective measures of medication errors may assist clinicians in identifying PD patients needing adherence strategies.

RESUMEN

OBJECTIVE: Although medication management is a necessary daily activity for individuals with Huntington's disease (HD), medication management abilities and their relation to cognitive functioning have not been evaluated. METHOD: Twenty individuals with HD and 20 healthy adults (HA) completed the Medication Management Abilities Assessment (MMAA). Individuals with HD also completed a self-report medication management measure and neuropsychological tests assessing executive function, retrospective memory, and prospective memory. RESULTS: Individuals with HD performed significantly poorer and made more undertaking errors on the MMAA as compared to HA. No group differences were found in overtaking errors. In the HD group, significant associations were found between undertaking errors and perceived medication management ability as well as between MMAA task performance and measures assessing prospective memory and executive functions. CONCLUSIONS: Medication management capacity was negatively affected in individuals with HD and may be associated with difficulty remembering to take medications in the future.

RESUMEN

OBJECTIVE: Difficulties managing medications, particularly among older adults experiencing cognitive deficits, is an important contributing factor to medication nonadherence that may have significant negative financial and health outcomes. The current study examined the performance of healthy older adults' (HOA) and individuals with amnestic mild cognitive impairment (aMCI) on the medication management abilities assessment's (MMAA, a performance-based measure of medication management) original scoring criteria and derived error process measures, assessing medication overtaking and undertaking magnitude. Exploratory correlations between performances on the MMAA and self-reported confidence in medication management skills and cognitive abilities were also examined. METHOD: A sample of 25 HOAs with aMCI and 25 age- and education-matched HOAs completed the MMAA, a self-reported medication management confidence rating and a battery of neuropsychological tests. RESULTS: HOAs performed significantly better on the MMAA score and committed significantly less process errors than individuals with aMCI. Despite these differences in MMAA performance, the HOA and aMCI groups rated similar high levels of confidence in their ability to manage a new medication routine. Notably, while the HOA group's performance on all of the MMAA measures did not relate to cognitive measures, the aMCI group's performance on the MMAA score was significantly related to memory and executive functioning and a new process error score for overtaking was related to processing speed. CONCLUSIONS: Although these results present promising potential for the MMAA as a measure of medication management in a clinical setting, further studies need to examine the validity of the MMAA against real-world adherence measures.

RESUMEN

Our study examined age-related differences on a new memory test assessing memory for "who," "when," and "where," and associations among these elements. Participants were required to remember a sequence of pictures of different faces paired with different places. Older adults remembered significantly fewer correct face-place pairs in the correct sequence compared with young adults. Correlation analyses with standardized neuropsychological tests provide preliminary evidence for construct validity. Our results offer insight into age-related changes in the ability to remember associations between people and places at different points in time using a portable test that can be administered rapidly in various settings.

RESUMEN

Age-related changes in temporal order memory have been well documented in older adults; however, little is known about this ability during middle age. We tested healthy young, middle-aged, and older adults on a previously published visuospatial temporal order memory test involving high and low interference conditions. When interference was low, young and middle-aged adults did not differ, but both groups significantly outperformed older adults. However, when interference was high, significant differences were found among all three age groups. The data provide evidence that temporal order memory may begin to decline in middle age, particularly when temporal interference is high.
