Vagal Recovery From Cognitive Challenge Moderates Age-Related Deficits in Executive Functioning

Decline in executive functioning (EF) is a hallmark of cognitive aging. We have previously reported that faster vagal recovery from cognitive challenge is associated with better EF. This study examined the association between vagal recovery from cognitive challenge and age-related differences in EF among 817 participants in the Midlife in the U.S. study (aged 35–86). Cardiac vagal control was measured as high-frequency heart rate variability. Vagal recovery moderated the association between age and EF (β = .811, p = .004). Secondary analyses revealed that older participants (aged 65–86) with faster vagal recovery had superior EF compared to their peers who had slower vagal recovery. In contrast, among younger (aged 35–54) and middle-aged (aged 55–64) participants, vagal recovery was not associated with EF. We conclude that faster vagal recovery from cognitive challenge is associated with reduced deficits in EF among older, but not younger individuals

Aging is associated with a prefrontal lateral-medial shift during picture-induced negative affect

The capacity to adaptively respond to negative emotion is in part dependent upon lateral areas of the prefrontal cortex (PFC). Lateral PFC areas are particularly susceptible to age-related atrophy, which affects executive function (EF). We used structural and functional magnetic resonance imaging (MRI) to test the hypothesis that older age is associated with greater medial PFC engagement during processing of negative information, and that this engagement is dependent upon the integrity of grey matter structure in lateral PFC as well as EF. Participants (n = 64, 38–79 years) viewed negative and neutral scenes while in the scanner, and completed cognitive tests as part of a larger study. Grey matter probability (GMP) was computed to index grey matter integrity. FMRI data demonstrated less activity in the left ventrolateral PFC (VLPFC) and greater ventromedial PFC (VMPFC) activity with increasing age during negative-picture viewing. Age did not correlate with amygdala responding. GMP in VLPFC and EF were negatively associated with VMPFC activity. We conclude that this change from lateral to medial PFC engagement in response to picture-induced negative affect reflects decreased reliance on executive function-related processes, possibly associated with reduced grey matter in lateral PFC, with advancing age to maintain emotional functioning

The European Researchers’ Network Working on Second Victim (ERNST) policy statement on the second victim phenomenon for increasing patient safety

Publisher Copyright: Copyright © 2024 Mira, Carillo, Tella, Vanhaecht, Panella, Seys, Ungureanu, Sousa, Buttigieg, Vella-Bonanno, Popovici, Srulovici, Guerra-Paiva, Knezevic, Lorenzo, Lachman, Ushiro, Scott, Wu and Strametz.Background: The second victim phenomenon refers to the emotional trauma healthcare professionals experience following adverse events (AEs) in patient care, which can compromise their ability to provide safe care. This issue has significant implications for patient safety, with AEs leading to substantial human and economic costs. Analysis: Current evidence indicates that AEs often result from systemic failures, profoundly affecting healthcare workers. While patient safety initiatives are in place, the psychological impact on healthcare professionals remains inadequately addressed. The European Researchers’ Network Working on Second Victims (ERNST) emphasizes the need to support these professionals through peer support programs, systemic changes, and a shift toward a just culture in healthcare settings. Policy Options: Key options include implementing peer support programs, revising the legal framework to decriminalize honest errors, and promoting just culture principles. These initiatives aim to mitigate the second victim phenomenon, enhance patient safety, and reduce healthcare costs. Conclusion: Addressing the second victim phenomenon is essential for ensuring patient safety. By implementing supportive policies and fostering a just culture, healthcare systems can better manage the repercussions of AEs and support the wellbeing of healthcare professionals.publishersversionpublishe

Age differences in reaction time and attention in a national telephone sample of adults: Education, sex, and task complexity matter

This study demonstrated effects of age, education, and sex on complex reaction time in a large national sample (N � 3,616) with a wide range in age (32–85) and education. Participants completed speeded auditory tasks (from the MIDUS [Midlife in the U.S.] Stop and Go Switch Task) by telephone. Complexity ranged from a simple repeated task to an alternating task that involved central executive processes including attention switching and inhibitory control. Increased complexity was associated with slower responses in older adults, those with lower education, and women, even after controlling for differences in health status. Higher levels of education were associated with greater central executive efficiency across adulthood: Overall, adults with college degrees performed on complex tasks like less educated individuals who were 10 years younger, up to age 75. These findings suggest that advanced education can moderate age differences on complex speeded tasks that require central executive processes, at least up to the point in old age at which biological declines predominate. The approach demonstrates the utility of combining laboratory paradigms with survey methods to enable the study of larger, more diverse and representative samples across the lifespan

Frequent cognitive activity compensates for education differences in episodic memory

OBJECTIVES: To test the hypothesis that frequent participation in cognitive activities can moderate the effects of limited education on cognitive functioning. DESIGN: A national study of adult development and aging, Midlife in the United States, with assessments conducted at the second wave of measurement in 2004-2006. SETTING: Assessments were made over the telephone (cognitive measures) and in a mail questionnaire (demographic variables, measures of cognitive and physical activity, and self-rated health). PARTICIPANTS: A total of 3,343 men and women between the ages of 32 and 84 with a mean age of 55.99 years. MEASUREMENTS: The dependent variables were Episodic Memory (Immediate and Delayed Word List Recall) and Executive Functioning (Category Fluency, Backward Digit Span, Backward Counting Speed, Reasoning, and Attention Switching Speed). The independent variables were years of education and frequency of cognitive activity (reading, writing, doing word games or puzzles, and attending lectures). The covariates were age, sex, self-rated health, income, and frequency of physical activity. RESULTS: The two cognitive measures were regressed on education, cognitive activity frequency, and their interaction, while controlling for the covariates. Education and cognitive activity were significantly correlated with both cognitive abilities. The interaction of education and cognitive activity was significant for episodic memory but not for executive functioning. CONCLUSION: Those with lower education had lower cognitive functioning, but this was qualified by level of cognitive activity. For those with lower education, engaging frequently in cognitive activities showed significant compensatory benefits for episodic memory, which has promise for reducing social disparities in cognitive aging

Monitoring cognitive functioning : psychometric properties of the brief test of adult cognition by telephone

Assessment of cognitive functioning is an important component of telephone surveys of health. Previous cognitive telephone batteries have been limited in scope with a primary focus on dementia screening. The Brief Test of Adult Cognition by Telephone (BTACT) assesses multiple dimensions central for effective functioning across adulthood: episodic memory, working memory, reasoning, verbal fluency, and executive function. The BTACT is the first instrument that includes measures of processing speed, reaction time, and task-switching/inhibitory control for use over the telephone. We administered the battery to a national sample (N = 4,268), age 32 to 84 years, from the study of Midlife in the United States (MIDUS) and examined age, education, and sex differences; reliability; and factor structure. We found good evidence for construct validity with a subsample tested in person. Implications of the findings are considered for efficient neuropsychological assessment and monitoring changes in cognitive aging, for clinical and research applications by telephone or in person
