Loneliness and Memory
>12,000; Age range: 34 to 93 years) were from three large longitudinal samples from the US and England. Measures of loneliness and demographic factors were obtained at baseline, cognitive, physical, and social activities were obtained from a second wave, and episodic memory was obtained from a third wave, 8 to 17 years later.ResultsA meta-analysis indicated that loneliness was prospectively associated with worse memory performance at follow-up, a…
Beyond words
Background: Thus far, no studies have focused on hugging and social disconnectedness outcomes comprehensively (loneliness, social isolation, social withdrawal) in the post-pandemic era. Our aim was to examine whether hugging is associated with loneliness, social isolation, and social withdrawal and whether these associations vary by gender. Methods: We used cross-sectional data collected via an online survey conducted in January 2025 (N = 3,270 a…
Momentary associations between purpose in life and social connection from a micro-longitudinal study of everyday life
There is a well-established association between purpose in life and social connection, measured cross-sectionally and longitudinally over years. The present study uses ecological momentary assessment to shrink the timescale to daily life to identify dynamic associations between purpose and social connection within and between assessments throughout the day. Participants (N = 303) reported their feelings of purpose and aspects of social connection…
Loneliness predicts mortality risk via the erosion of purpose in life
Loneliness is associated with premature mortality risk. Less is known about the mechanisms that may explain this association. Given its consequential health associations and relation to loneliness, purpose in life may one such mechanism. In a prospective rotating split-sample design from 2008-2010 to 2012-2014 with 11 years of mortality status follow-up, we tested purpose in life as an indirect pathway between loneliness and future risk of death.…
Elucidating the relationship between hearing loss, social isolation, and dementia
Moderate-severe hearing loss is associated with increased dementia risk-a relationship that appears moderated by social isolation status. This data may provide preliminary insights into potentially mediating effects. Further longitudinal research is needed to clarify this pathway and inform dementia prevention strategies

An exploration of sources of bias in population models of cognitive aging and accelerated decline
Linearized models of cognitive decline yielded high levels of bias that were sensitive to variations in study design and analytic choices. Results support shifting towards methods modeling accelerated decline in studies of cognitive aging and decline
Coping Styles as Mediators Between Purpose in Life and Cognitive Function
This study tests associations between purpose in life and coping, and whether coping mediates the association between purpose and cognitive function. Longitudinal data from the Midlife Development in the United States (MIDUS) study were used to investigate associations between purpose at MIDUS I and coping at MIDUS II ( N = 2386). Emotion-focused and problem-focused coping were tested as mediators between purpose and cognitive function (memory, e…
Purpose in life and accelerometer-measured physical activity among older adults
Objective Purpose in life is associated with engagement in physical activity and better cognitive health. This study examines the association between purpose in life and patterns of physical activity measured with an accelerometer and whether these patterns mediate the association between purpose and episodic memory among older adults.Methods and Measures This research is a secondary analysis of data from the accelerometry sub-study of the Nation…
Adverse childhood experiences and loneliness
From dysphoria to anhedonia
Cognitive-affective bridging symptoms differ with age, with anhedonia replacing dysphoria as the key bridge in older adults. This shift was linked to age-related differences in the relationship between GMV, cognition, and depressive symptoms. These results highlight the need to target different symptoms to alleviate cognitive-affective manifestations across the lifespan
Loneliness Links Adverse Childhood Experiences to Mortality Risk Across 26 Years
Objectives Adverse childhood experiences (ACEs) are associated with increased mortality risk. Individuals with a history of certain adversity during childhood tend to report higher levels of loneliness in later life. In our preregistered study, we examined whether loneliness mediates the ACEs to mortality risk relation. Methods Participants were from the Midlife in the United States Survey (N = 4,963; M [SD] = 46.44 [12.52] years, 53.3% female). …
Uncovering mechanisms of historical change in midlife loneliness across the United States and Europe
Our findings provide initial insights into the potential reasons behind historical trends of loneliness in the United States and European middle-aged adults. Our discussion elaborates on the reasons why physical activity, health conditions, and wealth contribute to historical changes in midlife loneliness
Nonlinear decline in the association between birth weight and cognitive ability from infancy to midlife in a community sample of twins
These findings suggest that prenatal experiences may have lasting effects on cognitive development across the lifespan, supporting developmental origin models of cognitive ability
Nonlinear Associations of Accelerometer-Based Sedentary Time With Cognitive Functions in the UK Biobank
Objectives Device-based sedentary time shows a nonlinear association with incident dementia among older adults. However, associations between sedentary time and cognitive performance have been inconsistent. We examined potential nonlinear associations between sedentary time and performance on cognitive tests among older adults. Methods We used data from the UK Biobank and included 32,875 adults aged 60–79. Sedentary time was estimated from a mach…
Effect of cognitive training on cortisol levels in patients with neurocognitive disorders
Cognitive training may help lower cortisol levels and enhance cognitive function in NCD patients, suggesting its potential as a nonpharmacological tool to modulate hypothalamic-pituitary-adrenal axis activity. Larger randomized studies are needed to confirm and extend these findings
Leisure activity and daily mood across adulthood
Objectives Leisure activities are known to promote health and well-being in adulthood, yet little is known about how different types and patterns of leisure engagement are associated with daily mood and which characteristics of leisure are more beneficial for adults at different stages of life, with varying work and family commitments. Methods Using 2-day time diaries from the 2019 Korean Time Use Survey (participant N = 22,821; age 20–84), this …
Overconfidence and Financial Risk Tolerance in Older Age
Objectives Excessive financial risk-taking in older age can have harmful consequences as opportunities to recover lost wealth are limited. Understanding financial risk-taking in older age is important for identifying vulnerabilities and developing interventions to empower aging investors to make wise financial choices. In this paper, we explore how overconfidence in financial knowledge affects financial risk-taking among older adults. Methods We …
Adolescent IQ and performance-based measures of physical function in old age
Objectives Early-life intellectual quotient (IQ) is a recognized predictor of overall health in late life. Building on this evidence, the present study examined the association between IQ in adolescence and performance-based measures of physical function in old age and tested potential mediators of this association. Methods Participants (N = 5,750) were from the Wisconsin Longitudinal Study. Measures of IQ and socioeconomic status were obtained i…
Regional Brain Volume and Cortical Thickness Mediate Age-Related Differences in Eye Movement Control
Objectives Eye movements (EMs) are considered biomarkers for age-related neurological or psychological deficits, and oculomotor control has been shown to strongly decline with age. This study aimed to understand the neural pathways of these age-related changes. Methods The analysis was based on 5,400 participants (aged 30–95 years) from the population-based Rhineland Study. EMs were recorded using video-based infrared oculography at 1,000 Hz. Bra…
Sustained Purpose in Life is Associated With Slower Cognitive Decline in Older Adults
Objectives Purpose in life is positively associated with cognitive function and better maintenance of cognitive function over time in aging adults. However, purpose in life itself declines over time, and we examined whether such changes are related to changes in cognition and whether this varied by race and ethnicity. Method The current study used 3 waves of data from the nationally representative survey, Health and Retirement Study (HRS; N = 9,8…
Resilience Through Social Connectedness and Cognition
Objective Social connectedness is a modifiable lifestyle factor that delays age-related cognitive decline. Using cross-sectional, longitudinal, and experimental approaches, we examined whether theory of mind—inferring what others think or feel—is a potential mechanism underlying this relationship. Methods In Study 1, 305 community-dwelling older adults participating in two different, but related, studies completed comprehensive measures of genera…
Loneliness and Biomarkers of Alzheimer’s Disease, Axonal Damage, and Astrogliosis
Objectives Loneliness is associated with an elevated risk of dementia. There is mixed evidence from imaging studies on whether loneliness is associated with neuropathology in dementia-free adults. This study tests whether loneliness is associated with plasma neurobiomarkers of amyloid (Aβ42/Aβ40), phosphorylated tau 181 (pTau181), neurofilament light chain (NfL), and glial fibrillary acidic protein (GFAP) and imaging measures of amyloid and tau. …
Associations between pain reactivity to worse sleep and health outcomes
Higher pain reactivity to worse sleep was associated with more concurrent distress but not distress over time or risk of chronic conditions. Future directions are to examine the influence of pain reactivity to worse sleep in larger and more diverse samples across longer follow-up
Investigating the trivariate reciprocal longitudinal relationships between purpose, loneliness, and cognitive function
Objectives As medical interventions for cognitive decline and dementia continue to evolve, the identification of modifiable psychosocial factors has become increasingly important. Sense of purpose and loneliness represent potential targets for intervention. In this study, we aimed to understand the potentially reciprocal relationship between sense of purpose, loneliness, and cognitive function. Methods The current project draws upon data from the…
The trajectory of loneliness in response to Covid-19
Social distancing and "stay-at-home" orders are essential to contain the coronavirus outbreak (COVID-19), but there is concern that these measures will increase feelings of loneliness, particularly in vulnerable groups. The present study examined change in loneliness in response to the social restriction measures taken to control the coronavirus spread. A nationwide sample of American adults ( N = 1,545; 45% women; ages 18 to 98, M = 53.68, SD = …
