RESUMEN
BACKGROUND: Aging is associated with an increasing risk of decline in cognitive abilities. The decline is, however, not a homogeneous process. There are substantial differences across individuals although previous investigations have identified individuals with distinct cognitive trajectories. Evidence is accumulating that lifestyle contributes significantly to the classification of individuals into various clusters. How and whether genetically related individuals, like twins, change in a more similar manner is yet not fully understood. METHODS: In this study, we fitted growth mixture models to Mini Mental State Exam (MMSE) scores from participants of the Swedish OCTO twin study of oldest-old monozygotic and same-sex dizygotic twins with the purpose of investigating whether twin pairs can be assigned to the same class of cognitive change. RESULTS: We identified four distinct groups (latent classes) whose MMSE trajectories followed different patterns of change over time: two classes of high performing individuals who remained stable and declined slowly, respectively, a group of mildly impaired individuals with a fast decline and a small group of impaired individuals who declined more rapidly. Notably, our analyses show no association between zygosity and class assignment. CONCLUSIONS: Our study provides evidence for a more substantial impact of environmental, rather than genetic, influences on cognitive change trajectories in later life.

BACKGROUND: Cognitive dispersion, or inconsistencies in performance across cognitive domains, has been posited as a cost-effective tool to predict conversion to dementia in older adults. However, there is a dearth of studies exploring cognitive dispersion in the oldest-old (>80 years) and its relationship to dementia incidence. OBJECTIVE: The main aim of this study was to examine whether higher cognitive dispersion at baseline was associated with dementia incidence within an 8-year follow-up of very old adults, while controlling for established risk factors and suggested protective factors for dementia. METHODS: Participants (n = 468) were from the Origins of Variance in the Old-Old: Octogenarian Twins study, based on the Swedish Twin Registry. Cox regression analyses were performed to assess the association between baseline cognitive dispersion scores and dementia incidence, while controlling for sociodemographic variables, ApoEe4 carrier status, co-morbidities, zygosity and lifestyle engagement scores. An additional model included a composite of average cognitive performance. RESULTS: Cognitive dispersion and ApoEe4 were significantly associated with dementia diagnosis. These variables remained statistically significant when global cognitive performance was entered into the model. Likelihood ratio tests revealed that cognitive dispersion and cognitive composite scores entered together in the same model was superior to either predictor alone in the full model. CONCLUSIONS: The study underscores the usefulness of cognitive dispersion metrics for dementia prediction in the oldest-old and highlights the influence of ApoEe4 on cognition in very late age. Our findings concur with others suggesting that health and lifestyle factors pose little impact upon cognition in very advanced age.

BACKGROUND: frailty shows an upward trajectory with age, and higher levels increase the risk of mortality. However, it is less known whether the shape of frailty trajectories differs by age at death or whether the rate of change in frailty is associated with mortality. OBJECTIVES: to assess population frailty trajectories by age at death and to analyse whether the current level of the frailty index (FI) i.e. the most recent measurement or the person-specific rate of change is more predictive of mortality. METHODS: 3,689 individuals from three population-based cohorts with up to 15 repeated measurements of the Rockwood frailty index were analysed. The FI trajectories were assessed by stratifying the sample into four age-at-death groups: <70, 70-80, 80-90 and >90 years. Generalised survival models were used in the survival analysis. RESULTS: the FI trajectories by age at death showed that those who died at <70 years had a steadily increasing trajectory throughout the 40 years before death, whereas those who died at the oldest ages only accrued deficits from age ~75 onwards. Higher level of FI was independently associated with increased risk of mortality (hazard ratio 1.68, 95% confidence interval 1.47-1.91), whereas the rate of change was no longer significant after accounting for the current FI level. The effect of the FI level did not weaken with time elapsed since the last measurement. CONCLUSIONS: Frailty trajectories differ as a function of age-at-death category. The current level of FI is a stronger marker for risk stratification than the rate of change.

Objectives: Retirement is a major life transition in the second half of life, and it can be associated with changes in leisure activity engagement. Although theories of retirement adjustment have emphasized the need to find meaningful activities in retirement, little is known about the nature of changes in leisure activity during the retirement transition and their association with mental health.Methods: Based on four annual waves of the 'Health, Aging and Retirement Transitions in Sweden' study, we investigated the longitudinal association of leisure activity engagement and depressive symptoms using bivariate dual change score models. We distinguished intellectual, social, and physical activity engagement.Results: We found increases in all three domains of activity engagement after retirement. Although level and change of activity and depressive symptoms were negatively associated, the coupling parameters were not significant, thus the direction of effects remains unclear.Conclusion: The results highlight the need to consider the role of lifestyle changes for retirement adjustment and mental health.

BACKGROUND: Web-surveys are increasingly used in population studies. Yet, web-surveys targeting older individuals are still uncommon for various reasons. However, with younger cohorts approaching older age, the potentials for web-surveys among older people might be improved. In this study, we investigated response patterns in a web-survey targeting older adults and the potential importance of offering a paper-questionnaire as an alternative to the web-questionnaire. METHODS: We analyzed data from three waves of a retirement study, in which a web-push methodology was used and a paper questionnaire was offered as an alternative to the web questionnaire in the last reminder. We mapped the response patterns, compared web- and paper respondents and compared different key outcomes resulting from the sample with and without the paper respondents, both at baseline and after two follow-ups. RESULTS: Paper-respondents, that is, those that did not answer until they got a paper questionnaire with the last reminder, were more likely to be female, retired, single, and to report a lower level of education, higher levels of depression and lower self-reported health, compared to web-respondents. The association between retirement status and depression was only present among web-respondents. The differences between web and paper respondents were stronger in the longitudinal sample (after two follow-ups) than at baseline. CONCLUSIONS: We conclude that a web-survey might be a feasible and good alternative in surveys targeting people in the retirement age range. However, without offering a paper-questionnaire, a small but important group will likely be missing with potential biased estimates as the result.

OBJECTIVE: Research on retirement suggests that personality can influence the adjustment process, but the mechanisms involved remain still largely unknown. In the present study, we investigate direct and indirect associations between the Big Five personality traits and life satisfaction over the retirement transition. Indirect effects were evaluated through the role of personality for levels and changes in self-esteem, autonomy, social support, self-rated physical health, self-rated cognitive ability, and financial satisfaction. METHOD: Our sample consisted of 796 older adults (age 60-66) and four annual measurement waves from the longitudinal population-based HEalth, Ageing, and Retirement Transitions in Sweden (HEARTS) study, including individuals retiring during the study period. RESULTS: Results from multivariate latent growth curve analysis revealed multiple indirect associations between personality and life satisfaction. Extraversion, Agreeableness, and Conscientiousness were positively related to life satisfaction through higher levels of self-esteem, autonomy, and social support. Neuroticism was negatively associated with life satisfaction through lower levels of self-esteem and lower levels and negative changes in autonomy and social support. CONCLUSIONS: Our findings suggest that retirees with higher levels of Neuroticism are more vulnerable in the transition process and they are also more likely to experience adjustment problems resulting from negative changes in key resources.

To improve health care for older persons, we need to learn more about ageing, e.g. identify protective factors and early markers for diseases. The Gothenburg H70 Birth Cohort Studies (the H70 studies) are multidisciplinary epidemiological studies examining representative birth cohorts of older populations in Gothenburg, Sweden. So far, six birth cohorts of 70-year-olds have been examined over time, and examinations have been virtually identical between studies. This paper describes the study procedures for the baseline examination of the Birth cohort 1944, conducted in 2014-16. In this study, all men and women born 1944 on specific dates, and registered as residents in Gothenburg, were eligible for participation (n = 1839). A total of 1203 (response rate 72.2%; 559 men and 644 women; mean age 70.5 years) agreed to participate in the study. The study comprised sampling of blood and cerebrospinal fluid, psychiatric, cognitive, and physical health examinations, examinations of genetics and family history, use of medications, social factors, functional ability and disability, physical fitness and activity, body composition, lung function, audiological and ophthalmological examinations, diet, brain imaging, as well as a close informant interview, and qualitative studies. As in previous examinations, data collection serves as a basis for future longitudinal follow-up examinations. The research gained from the H70 studies has clinical relevance in relation to prevention, early diagnosis, clinical course, experience of illness, understanding pathogenesis and prognosis. Results will increase our understanding of ageing and inform service development, which may lead to enhanced quality of care for older persons.

Objectives: The retirement transition is a multidimensional and dynamic process of adjustment to new life circumstances. Research has shown that individual differences in resource capability accounts for a substantial amount of the previously observed heterogeneity in retirement adjustment. The aim of the present study was to investigate interaction effects of self-esteem, autonomy, social support, self-rated physical health, self-rated cognitive ability, and basic financial resources on levels and changes in life satisfaction in the retirement transition. Method: Our sample included 1924 older adults from the longitudinal population-based HEalth, Ageing, and Retirement Transitions in Sweden (HEARTS) study. The participants were assessed annually over a three-year period, covering the transition from work to retirement (n = 614). Participants continuously working (n = 1310) were included as a reference group. Results: Results from latent growth curve models showed that the relationship between a particular resource and levels and changes in life satisfaction varied depending on other available resources, but also that these effects varied between retirees and workers. Autonomy moderated the effect of physical resources, and social support and perceived cognitive ability moderated the effect of financial resources. Discussion: Our findings add to the current knowledge on retirement adjustment and suggest that negative effects of poor health and lack of basic financial resources on retirees life satisfaction may be compensated for by higher levels of autonomy, social support, and perceived cognitive ability.

Background: previous research has demonstrated how older adults exhibit different patterns of change in cognitive and physical functioning, suggesting differences in the underlying causal processes. Objective: to (i) identify subgroups of older adults that best account for different patterns of longitudinal change in performance on global cognition and grip strength, (ii) examine the interrelationship between global cognition and grip strength trajectories within these subgroups and (iii) identify demographic and health-related markers of class membership. Methods: multivariate growth mixture models (GMM) were used to identify groups of individuals with similar developmental trajectories of muscle strength measured by grip strength, and global cognition measured by Mini Mental State Examination (MMSE). Results: GMM analyses indicated high, moderate and low functioning groups. Individuals in the high and moderate classes demonstrated better cognitive and physical functioning at the start of the study and less decline than those in the low functioning group. Notably, cognitive performance was related to physical functioning at study entry only among individuals in the low functioning group. Conclusion: the study demonstrates the applicability of the multivariate GMM to achieve a better understanding of the heterogeneity of various aging related processes.

ABSTRACTBackground:A recently published study suggests that Gamma-Glutamyltransferase (GGT) in midlife is related to an increased risk of dementia. In the present longitudinal study, we explore the effects of serum GGT on cognitive decline and dementia also in more advanced ages. METHODS: We analyzed GGT in a sample of 452 individuals, aged 80 years and older at baseline, with the purpose to explore subsequent effects on cognitive performance. We specifically modeled GGT to cognitive change, time to death, and dementia. RESULTS: Our main finding is that a higher level of GGT is associated with cognitive decline prior to death and vascular dementia in late life. These findings were evident across cognitive domains. CONCLUSIONS: This is the first longitudinal study to report on significant associations in late life between GGT, cognitive performance and dementia. Further research is needed to examine the underlying mechanisms of GGT as a marker of age-related cognitive decline.

INTRODUCTION: Few longitudinal studies assessed whether sleep disturbances are associated with dementia risk. METHODS: Sleep disturbances were assessed in three population-based studies (H70 study and Kungsholmen Project [Sweden]; Cardiovascular Risk Factors, Aging and Dementia study [Finland]). Late-life baseline analyses (3-10 years follow-up) used all three studies (N = 1446). Baseline ages ≈ 70 years (Cardiovascular Risk Factors, Aging and Dementia, H70), and ≈84 years (Kungsholmen Project). Midlife baseline (age ≈ 50 years) analyses used Cardiovascular Risk Factors, Aging and Dementia (21 and 32 years follow-up) (N = 1407). RESULTS: Midlife insomnia (fully adjusted hazard ratio = 1.24, 95% confidence interval = 1.02-1.50) and late-life terminal insomnia (fully adjusted odds ratio = 1.94, 95% confidence interval = 1.08-3.49) were associated with a higher dementia risk. Late-life long sleep duration (>9 hours) was also associated with an increased dementia risk (adjusted odds ratio = 3.98, 95% confidence interval = 1.87-8.48). DISCUSSION: Midlife insomnia and late-life terminal insomnia or long sleep duration were associated with a higher late-life dementia risk.

INTRODUCTION: This study examines the role of educational attainment, an indicator of cognitive reserve, on transitions in later life between cognitive states (normal Mini-Mental State Examination (MMSE), mild MMSE impairment, and severe MMSE impairment) and death. METHODS: Analysis of six international longitudinal studies was performed using a coordinated approach. Multistate survival models were used to estimate the transition patterns via different cognitive states. Life expectancies were estimated. RESULTS: Across most studies, a higher level of education was associated with a lower risk of transitioning from normal MMSE to mild MMSE impairment but was not associated with other transitions. Those with higher levels of education and socioeconomic status had longer nonimpaired life expectancies. DISCUSSION: This study highlights the importance of education in later life and that early life experiences can delay later compromised cognitive health. This study also demonstrates the feasibility and benefit in conducting coordinated analysis across multiple studies to validate findings.

OBJECTIVE: Internet-delivered cognitive behavioral therapy (ICBT) is recommended as an efficient treatment alternative for depression in primary care. However, only few previous studies have been conducted at primary care centers (PCCs). We evaluated long-term effects of ICBT treatment for depression compared to treatment as usual (TAU) in primary care settings. DESIGN: Randomized controlled trial. SETTING: Patients were enrolled at16 PCCs in south-west Sweden. PARTICIPANTS: Patients attending PCCs and diagnosed with depression (n = 90). INTERVENTIONS: Patients were assessed by a primary care psychologist/psychotherapist and randomized to ICBT or TAU. The ICBT included an ICBT program consisting of seven modules and weekly therapist e-mail or telephone support during the 3-month treatment period. MAIN OUTCOME MEASURES: Questionnaires on depressive symptoms (BDI-II), quality of life (EQ-5D) and psychological distress (GHQ-12) were administered at baseline, with follow-ups at 3, 6 and 12 months. Antidepressants and sedatives use, sick leave and PCC contacts were registered. RESULTS: Intra-individual change in depressive symptoms did not differ between the ICBT group and the TAU group during the treatment period or across the follow-up periods. At 3-month follow-up, significantly fewer patients in ICBT were on antidepressants. However, the difference leveled out at later follow-ups. There were no differences between the groups concerning psychological distress, sick leave or quality of life, except for a larger improvement in quality of life in the TAU group during the 0- to 6-month period. CONCLUSIONS: ICBT with weekly minimal therapist support in primary care can be equally effective as TAU among depressed patients also over a 12-month period. CLINICAL TRIAL REGISTRATION: The trial was registered in the Swedish Registry, researchweb.org, ID number 30511.

OBJECTIVE: Cognitive performance shows a marked deterioration in close proximity to death, as postulated by the terminal decline hypothesis. The effect of education on the rate of terminal decline in the oldest people (i.e. persons 85+ years) has been controversial and not entirely understood. In the current study, we investigated the rate of decline prior to death with a special focus on the role of education and socioeconomic position, in two European longitudinal studies of ageing: the Origins of Variance in the Old-Old: Octogenarian Twins (OCTO-Twin) and the Newcastle 85+ study. METHODS: A process-based approach was used in which individuals' cognitive scores were aligned according to distance to death. In a coordinated analysis, multilevel models were employed to examine associations between different markers of cognitive reserve (education and socioeconomic position) and terminal decline using the mini-mental state examination (MMSE), controlling for age at baseline, sex, dementia incidence and time to death from the study entry to the time of death within each cohort. RESULTS: The current findings suggest that education was positively associated with higher MMSE scores prior to death in the OCTO-Twin, but not in the Newcastle 85+ study, independent of socioeconomic position and other factors such as baseline age, sex and time to death from the study entry. However, education was not associated with the rate of terminal decline in both of these studies. CONCLUSIONS: Our results offer only partial support to the cognitive reserve hypothesis and cognitive performance prior to death.

BACKGROUND AND RESEARCH OBJECTIVE: An increasing body of evidence shows that individuals diagnosed with congestive heart failure (CHF) are at a higher risk for dementia. However, the prevalence rate of dementia among persons with CHF in very old individuals has not been previously reported, and little is known about the comorbidities that place old persons with CHF at a higher risk for dementia. The aim of this study was to compare the prevalence of dementia in individuals 80 years or older who have CHF with that in individuals without CHF and to identify factors related to dementia in individuals diagnosed with CHF. METHODS: A total of 702 participants from a Swedish population-based longitudinal study (Octogenerian Twin) were included. The group consisted of same-sex twin pairs, age 80 years or older, and 138 participants had CHF. Dementia was diagnosed according to criteria in the Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised. Generalized estimating equations including gender, age and educational level, waist circumference, diabetes, hypertension, smoking, depression, and blood values were used in a case-control analysis. RESULTS: Individuals with CHF had a significantly higher prevalence of vascular dementia, 16% vs 6% (P < 0.001), and of all types of dementia, 40% vs 30% (P < 0.01), than those not diagnosed with CHF. The generalized estimating equation models showed that depression, hypertension, and/or increased levels of homocysteine were all associated with a higher risk for dementia in individuals with CHF. Diabetes was specifically associated with an increased risk for vascular dementia. CONCLUSIONS: The prevalence of dementia was higher among individuals with CHF than in those without CHF. Diabetes, depression, and hypertension in patients with CHF require special attention from healthcare professionals because these conditions are associated with an elevated risk for dementia. Higher levels of homocysteine were also found to be a marker of dementia in patients with CHF. Further research is needed to identify the factors related to dementia in individuals 80 years or older diagnosed with CHF.

Depression presents a serious condition for the individual and a major challenge to health care and society. Internet-based cognitive behavior therapy (ICBT) is a treatment option supported in several trials, but there is as yet a lack of effective studies of ICBT in "real world" primary care settings. We examined whether ICBT differed from treatment-as-usual (TAU) in reducing depressive symptoms after 3 months. TAU comprised of visits to general practitioner, registered nurse, antidepressant drugs, waiting list for, or psychotherapy, or combinations of these alternatives. Patients, aged ≥ 18 years, who tentatively met criteria for mild to moderate depression at 16 primary care centers in the south-western region of Sweden were recruited and then assessed in a diagnostic interview. A total of 90 patients were randomized to either TAU or ICBT. The ICBT treatment included interactive elements online, a workbook, a CD with mindfulness and acceptance exercises, and minimal therapist contact. The treatment period lasted for 12 weeks after which both groups were assessed. The main outcome measure was Beck Depression Inventory-II (BDI-II). Additional measures were Montgomery Åsberg Depression Rating Scale - self rating version (MADRS-S) and Beck Anxiety Inventory (BAI). The analyses revealed no significant difference between the two groups at post treatment, neither on BDI-II, MADRS-S, nor BAI. Twenty patients (56%) in the ICBT treatment completed all seven modules. Our findings suggest that ICBT may be successfully delivered in primary care and that the effectiveness, after 3 months, is at par with TAU.

Little is known about birth cohort differences in the impact of stroke on cognitive aging. Given improved poststroke rehabilitation and better treatments for vascular health risk, we may expect a reduction in the stroke impact in later-born cohorts. We tested this prediction using data from two cohorts, born in 1901-1907 (n = 1,155) and 1930 (n = 919), identified from the same city population at the same age of 70 and subsequently measured on the same cognitive outcomes (i.e., spatial ability, perceptual-motor speed, and reasoning) at ages 70, 75, 79, and 85. We fitted multiple-group second-order latent growth curve models to the data, regressing the first-order cognitive factor on the time-varying stroke variable and controlling for relevant covariates. Findings revealed moderate to large average cognitive decline (d = -.45) following stroke, and the impact was relatively similar across cohorts (1901-1907: d = -.52; 1930: d = -.39). However, there was a stroke by age by cohort interaction, implying that the stroke impact increased with age in the 1901-1907 cohort (dage ≤ 75 = -.42; dage ≥ 79 = -.70) but decreased in the 1930 cohort (dage ≤ 75 = -.53; dage ≥ 79 = -.17). We found no evidence for lagged effect of stroke beyond the impact on measures following the incidence. Our hypothesis was only partially supported, as the impact of stroke was reduced in the later-born cohort but solely at higher ages. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

OBJECTIVE: To investigate the psychological needs of patients diagnosed with testicular cancer. PATIENTS AND METHODS: We identified 1192 eligible men diagnosed with non-seminomatous testicular cancer, treated according to the bi-national cancer-care programmes SWENOTECA I-IV between 1981 and 2004. Using a study-specific questionnaire we asked the survivors if they had experienced some kind of crisis attributable to their cancer diagnosis. We also asked if they were and, if not, if they wish they had been offered information about crisis and stress reactions and professional counselling. RESULTS: We obtained information from 974/1192 (82%) testicular cancer survivors diagnosed at a mean of 11 years before follow-up. Sixty-three percent reported that they had experienced a crisis owing to their diagnosis. For most men (76%) the crisis was at its worst at the time of diagnosis and treatment. Between 1981 and 2004, 145 men (15%) reported that they received information about common stress and crisis reactions and 348 (36%) reported that they were offered counselling. Of the men not informed about stress and crisis reactions and not offered counselling, 353/514 (69%) and 251/403 (62%), respectively, wish they had been. The percentage who reported that they wish that they had been informed or offered counselling did not differ significantly depending on civil status, age at diagnosis or stage of disease. CONCLUSIONS: The vast majority of Swedish testicular cancer survivors reported that they experienced a crisis because of their cancer diagnosis. Moreover, regardless of stage of disease, most men reported a need for psychological support at the time of diagnosis and treatment that was not satisfactorily met by the healthcare provision.

The Interplay of Genes and Environment across Multiple Studies (IGEMS) group is a consortium of eight longitudinal twin studies established to explore the nature of social context effects and gene-environment interplay in late-life functioning. The resulting analysis of the combined data from over 17,500 participants aged 25-102 at baseline (including nearly 2,600 monogygotic and 4,300 dizygotic twin pairs and over 1,700 family members) aims to understand why early life adversity, and social factors such as isolation and loneliness, are associated with diverse outcomes including mortality, physical functioning (health, functional ability), and psychological functioning (well-being, cognition), particularly in later life.

BACKGROUND: The purpose of the study was to examine the attention deficit hyperactivity disorder (ADHD) symptomatology across the lifespan by comparing older individuals' self-reports about current ADHD symptoms and symptoms in childhood. METHODS: The 25-item Wender Utah Rating Scale (WURS) was initially administered in a population-based sample of 1,599 persons aged 65-80 years. We also asked about current health, memory, and problems in childhood. Based on their WURS scores (below and above 36), we randomly drew two subsamples, each with 30 individuals. They were followed up by the Wender Riktad ADHD Symtom Skala (WRASS)-scale, a Swedish version of the Targeted Attention Deficit Disorder Rating Scale (TADDS). RESULTS: Our main finding was that higher WURS scores were significantly related to higher scores on the WRASS scale, indicating persistence of self-reported ADHD symptoms over the whole lifespan. Among those with a WURS score of 36 or more, 16 (53.3%) individuals scored 70 or more; the clinical cut-off used in Sweden. None of the individuals with a WURS score below 36 scored higher than 70 on the WRASS scale. CONCLUSIONS: Our findings support the idea of a significant persistence of ADHD symptoms from childhood to old age. The results encourage studies of ADHD using a lifespan perspective, particularly in examining ADHD symptoms in old age.
