  • Feelings of hopelessness in midlife are associated with dementia risk in later life
  • 2012

    • Background: Although an association between depressive feelings and dementia has been estab- lished previously, the nature of this relation remains unclear. Establishing causality has been com- plicated by the typical use of a short follow-up and aged participants already at baseline. The aim with this study was to investigate the association between feelings of hopelessness in midlife and cognitive impairment in later life.Methods: From a representative population in Eastern Finland, originally investigated between 1972-1987, a random sample of 2000 survivors was invited for re-examination in 1998, averagely 21 years later. The mean age of the 1449 persons who accepted the invitation was 50.4 (range 39-64) at baseline and 71.3 years (range 65-80) at follow-up. Baseline scores of hopelessness were related to cognitive status at follow-up, mainly through logistic regression. Adjustments were made for age, years of education, gender, APOE4 and a number of health and life style factors at baseline. In addition we analyzed differences in hopelessness scores between baseline and follow-up within the different outcome groups.Results: Participants with high levels of hopelessness at midlife had more than a doubled risk of cognitive impairment in later life as expressed by an odds ratio of 2.24 (1.4-3.6), even higher spe- cifically for Alzheimers disease. Persons with high levels of hopelessness at midlife and who in addition carried the apolipoprotein allele 4 (ApoE ε4) had a highly elevated risk of Alzheimers dis- ease. There were no significant differences in levels of hopelessness between baseline and follow-up within any of the outcome groups.Conclusions: The results confirm previous studies showing elevated scores of depressive feelings in persons diagnosed with dementia, compared to cognitively healthy persons. On the other hand, the results also suggest that the major portion of this difference could have existed already decades before the dementia diagnosis; Carrying feelings of hopelessness in midlife may have long-term implications for cognitive health in later life. Background: Although an association between depressive feelings and dementia has been estab- lished previously, the nature of this relation remains unclear.

  • Association between mid-life marital status and cognitive function in later life : population based cohort study
  • 2009
  • Ingår i: The BMJ. - : BMJ. - 1756-1833 .- 0959-8138 .- 1468-5833. ; 339:July, s. Article number: b2462-

    • Objectives To evaluate whether mid-life marital status is related to cognitive function in later life. Design Prospective population based study with an average follow-up of 21 years. Setting Kuopio and Joensuu regions in eastern Finland. Participants Participants were derived from random, population based samples previously investigated in 1972, 1977, 1982, or 1987; 1449 individuals (73%), aged 65-79, underwent re-examination in 1998. Main outcome measures Alzheimer's disease and mild cognitive impairment. Results People cohabiting with a partner in mid-life (mean age 50.4) were less likely than all other categories (single, separated, or widowed) to show cognitive impairment later in life at ages 65-79. Those widowed or divorced in mid-life and still so at follow-up had three times the risk compared with married or cohabiting people. Those widowed both at mid-life and later life had an odds ratio of 7.67 (1.6 to 40.0) for Alzheimer's disease compared with married or cohabiting people. The highest increased risk for Alzheimer's disease was in carriers of the apolipoprotein E e4 allele who lost their partner before mid-life and were still widowed or divorced at follow-up. The progressive entering of several adjustment variables from mid-life did not alter these associations. Conclusions Living in a relationship with a partner might imply cognitive and social challenges that have a protective effect against cognitive impairment later in life, consistent with the brain reserve hypothesis. The specific increased risk for widowed and divorced people compared with single people indicates that other factors are needed to explain parts of the results. A sociogenetic disease model might explain the dramatic increase in risk of Alzheimer's disease for widowed apolipoprotein E e4 carriers.

  • Midlife improvements in financial situation are associated with a reduced dementia risk later in life : the CAIDE 30-year study
  • 2020
  • Ingår i: International psychogeriatrics. - : Cambridge University Press. - 1041-6102 .- 1741-203X. ; 32:11, s. 1317-1324

    • Objectives: Perceived financial strain is associated with various health conditions, but it is unknown whether it is associated with an increased risk for dementia. The goal is to examine the associations between midlife perceptions of financial situation and dementia risk later in life.Methods: Participants were derived from the Cardiovascular Risk Factors, Aging, and Dementia population-based cohort study (n = 2000) (between 1972 and 1987, baseline mean age 50 years) in Finland. Participants returned for two re-examinations in late life (in 1998 and 2005–2008, mean age 71 and 78 years). In this study, 1442 subjects that participated in at least one re-examination (mean total follow-up 25 years) were included in analyses. Financial strain was measured using two questions in midlife on perceptions of financial situation and perceptions of changes in financial situation. For each question, participants were categorized into three groups reporting improvement, worsening, or stability, with the latter set as the reference group. Analyses were adjusted for potential confounding factors.Results: The group reporting better financial situation had a reduced risk for dementia (fully adjusted model: odds ratio (OR): 0.53, 95% confidence interval (CI): 0.33–0.86). In contrast, the group reporting worse financial situation did not have an increased risk for dementia (OR: 1.04, 95% CI: 0.53–2.02). Analyses on perceptions of current financial situation showed that the groups reporting satisfaction or dissatisfaction with financial situation did not differ in risk for dementia.Conclusion: This study is the first to show that midlife improvements in financial situation are associated with a reduced dementia risk later in life. Potential pathways related to stress reduction, improved lifestyle, and potential biological mechanisms are discussed.
