In celebration of the National Institute on Aging's (NIA) 50th anniversary, this paper highlights the significant advances in cognitive aging research and the promotion of cognitive health among older adults. Since its inception in 1974, the NIA has played a pivotal role in understanding cognitive aging, including cognitive epidemiology, interventions, and methods, for measuring cognitive change. Key milestones include the shift toward understanding cognitive impairment and Alzheimer's disease and Alzheimer's disease-related dementias (AD/ADRD), the development of large-scale longitudinal studies, and the incorporation of AD/ADRD-related biomarkers in cognitive aging cohorts.

As the population ages, the number of older adults experiencing mild cognitive impairment (MCI), Alzheimer's disease, and other forms of dementia will increase dramatically over the next few decades. Unfortunately, cognitive changes associated with these conditions threaten independence and quality of life. To address this, researchers have developed promising cognitive training interventions to help prevent or reverse cognitive decline and cognitive impairment.

Adequate adherence is a necessary condition for success with any intervention, including for computerized cognitive training designed to mitigate age-related cognitive decline. Tailored prompting systems offer promise for promoting adherence and facilitating intervention success. However, developing adherence support systems capable of just-in-time adaptive reminders requires understanding the factors that predict adherence, particularly an imminent adherence lapse.

Background: Family caregivers play a vital, yet stressful role in managing the healthcare needs and optimizing the quality of life of patients with advanced cancer, from the time they are newly diagnosed until end of life. While early telehealth palliative care has been found to effectively support family caregivers, little work has focused on historically under-resourced populations, particularly African American and rural-dwelling individuals. To address this need, we developed and are currently testing Project ENABLE (Educate, Nurture, Advise, Before Life Ends) Cornerstone, a lay navigator-led, early palliative care coaching intervention for family caregivers of African American and rural-dwelling patients with newly diagnosed advanced cancer.

ObjectivesWe examined associations between three geographic areas (urban, suburban, rural) and cognition (memory, reasoning, processing speed) over a 10-year period. Data were obtained from 2539 participants in the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) trial. Multilevel, mixed-effects linear regression was used to estimate cognitive trajectories by geographical areas over 10 years, after adjusting for social determinants of health.

An ability discrepancy (crystallized minus fluid abilities) might be a personally relevant cognitive marker of risk for Alzheimer's disease (AD) and might help reduce measurement bias often present in traditional measures of cognition. In a large national sample of adults aged 60-104 years (N = 14,257), we investigated whether the intersectionality of group characteristics previously shown to pose a risk for AD including ethnoracial category, socioeconomic status, and sex (a) differed in ability discrepancy compared to traditional neuropsychological tests and (b) moderated the relationship between an ability discrepancy and AD symptom severity. In cognitively normal older adults, results indicated that across each decade, fluid and memory composite scores generally exhibited large group differences with sex, education, and ethnoracial category.

In the present study, we examined three experimental cognitive interventions, two targeted at training general cognitive abilities and one targeted at training specific instrumental activities of daily living (IADL) abilities, along with one active control group to compare benefits of these interventions beyond expectation effects, in a group of older adults ( = 230). Those engaged in general training did so with either the web-based brain game suite BrainHQ or the strategy video game Rise of Nations, while those trained on IADL skills completed instructional programs on driving and fraud awareness. Active control participants completed sets of puzzles.

Article Synopsis
  • The review examines the impact of racism in healthcare specifically on older African American adults, highlighting health disparities and medical mismanagement they face over their lifetimes.
  • Despite medical advancements leading to longer lifespans and better chronic illness management for many, older African American adults do not experience the same benefits.
  • These individuals are less likely to have effective management of their chronic conditions and are at a higher risk of dying from these illnesses compared to their White counterparts, indicating ongoing poor healthcare outcomes.

Article Synopsis
  • This study evaluated the ENABLE Cornerstone program, a telehealth support intervention for family caregivers of patients with advanced cancer, focusing on its feasibility, acceptability, and efficacy among African American/Black and rural caregivers.
  • Conducted from November 2019 to March 2021, the pilot trial randomized 63 caregivers to either the intervention, which included telehealth coaching sessions on stress management and self-care, or usual care.
  • Results showed that while only 65% of intervention sessions were completed, caregivers rated their likeliness to recommend the program very high (9.4/10), and the intervention group experienced less distress and a slight improvement in quality of life compared to those receiving usual care.

Purpose Of The Review: Experiences of patients, families, healthcare workers and health systems during the COVID-19 pandemic and recent national focus on racial justice have forced a reconsideration of policies and processes of providing care in crisis situations when resources are scarce. The purpose of this review is to present recent developments in conceptualizing ethical crisis standards.

Recent Findings: Several recent papers have raised concerns that "objective" scarce resource allocation protocols will serve to exacerbate underlying social inequities.

Purpose Of Review: Most aging Americans lack access to specialist palliative care aimed at those experiencing serious illness and/or high symptom burden at end of life. The curricula used by training programs for all healthcare professions should focus on helping learners develop the primary palliative care skills and competencies necessary to provide compassionate bias-free care for adults with serious illness. We believe there is much opportunity to improve this landscape via the incorporation of palliative care competencies throughout generalist healthcare professional programs.

Previous studies report hippocampal volume loss can help predict conversion from normative aging to mild cognitive impairment to dementia. Additionally, a growing literature indicates that stress-related allostatic load may increase disease vulnerability. The current study examined the relationship between stress-related cytokines (ie, interleukin-6 [IL-6]), cognition as measured by Mini-Mental State Examination (MMSE) scores, and hippocampal volume.

Interventions designed to preserve cognition have become increasingly popular as our population ages. In exploring intervention effectiveness, however, researchers have often overlooked a potentially important factor: willingness to engage. Recent findings from Harrell, Kmetz, Boot (2019) showed that perceived cognitive deficits and perceived training efficacy were significant predictors of willingness to engage in a brain training intervention designed to preserve cognition.

A cognitive intervention study was conducted with the purpose of exploring methods to improve adherence to a technology-based cognitive intervention and uncover individual differences that predict adherence (N = 120). The study was divided into two phases: Phase 1, in which participants were asked to follow a prescribed schedule of training that involved gamified neuropsychological tests administered via tablet, and Phase 2, in which participants were asked to play as frequently as they wished. Positive- and negative-framed messages about brain health were delivered via the software program, and measures of cognition, technology proficiency, self-efficacy, technology attitudes, and belief in the benefits of cognitive training were collected.
