Background: Frailty is a common geriatric syndrome associated with poor clinical outcomes. Effectiveness of lifestyle intervention programmes among frail older people has been examined earlier, but effects of interventions on prevention of frailty have been rarely studied. The aim of this study was to investigate to what extent the multidomain lifestyle intervention in the Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER) affected changes in frailty status among older men and women at risk of cognitive disorders.

This study investigated longitudinal physical activity (PA) profiles over 7 years in the Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER). Cognition, depression, pain, and PA motives were included as determinants of the PA profiles. The 1259 participants, aged 60-77 years at baseline, were randomized into either a control group receiving general health advice, or an intervention group offered a comprehensive 2-year multidomain intervention including physical exercise, diet advice, cognitive training, and vascular risk factor management.

Social death refers to situations in which individuals become socially excluded from social interaction or are considered socially insignificant. Social death is about losing roles, relationships, and eventually identity in the eyes of others. When becoming a permanent resident in a nursing home, older adults face an increased risk of social death.

Background: We examined individual and dual trajectories of insomnia symptoms and body mass index (BMI) before and after retirement, and their associations with changes in subjective cognitive functioning after retirement.

Methods: We used the Helsinki Health Study's (n = 2360, 79% women, aged 40-60 at baseline, Finland) repeated surveys to identify the developmental patterns of insomnia symptoms and BMI (2000-2017) and changes in subjective cognitive functioning (2017-2022). We analysed the data using latent group-based dual trajectory modelling and logistic regression analysis.

Background: Physical and cognitive interventions have been shown to induce positive effects on older adults' executive functioning. However, since participants with different background characteristics may respond differently to such interventions, we investigated whether training effects on executive functions were associated with sex, training compliance, and age. We also investigated if change in global cognition was associated with physical and cognitive training intervention-induced changes in executive functions.

With population ageing worldwide, dementia poses one of the greatest global challenges for health and social care in the 21st century. In 2019, around 55 million people were affected by dementia, with the majority living in low- and middle-income countries. Dementia leads to increased costs for governments, communities, families and individuals.

The COVID-19 pandemic and its related restrictions have affected the everyday life of older people. Advanced age is a significant predisposing factor for a more severe COVID-19 infection, increasing the risk for hospitalization and mortality. Even though restrictions have been, thus, well-grounded, they may also have had detrimental effects on the social well-being of older people.

The first WHO guidelines for risk reduction of cognitive decline and dementia marked an important milestone in the field of dementia prevention. In this paper, we discuss the evidence reviewed as part of the guidelines development and present the main themes emerged from its synthesis, to inform future research and policies on dementia risk reduction. The role of intervention effect-size; the mismatch between observational and intervention-based evidence; the heterogeneity of evidence among intervention trials; the importance of intervention duration; the role of timing of exposure to a certain risk factor and interventions; the relationship between intervention intensity and response; the link between individual risk factors and specific dementia pathologies; and the need for tailored interventions emerged as the main themes.

Although prevention of dementia and late-life cognitive decline is a major public health priority, there are currently no generally established prevention strategies or operational models for implementing such strategies into practice. This article is a narrative review of available evidence from multidomain dementia prevention trials targeting several risk factors and disease mechanisms simultaneously, in individuals without dementia at baseline. Based on the findings, we formulate recommendations for implementing precision risk reduction strategies into new services called Brain Health Services.

In many countries, the COVID-19 pandemic has led to strong restrictions and changed the everyday lives of older people. In Finland, people aged 70 and over were instructed to stay at home under quarantine-like conditions. Existing studies from other countries have reported increases in negative experiences and symptoms as a result of such restrictions, including psychosocial stress.

Walking is a complex task requiring the interplay of neuromuscular, sensory, and cognitive functions. Owing to the age-related decline in cognitive and physical functions, walking may be compromised in older adults, for cognitive functions, especially poor performance in executive functions, is associated with slow walking speed. Hence, the aim of this study was to investigate the associations between different subdomains of executive functions and physical functions and whether the associations found differ between men and women.

Background: The Finnish Intervention Study to Prevent Cognitive Impairment and Disability is a randomized controlled trial that has tested the efficacy of a multidomain intervention targeting modifiable risk factors to prevent cognitive impairment/dementia. A combination of healthy diet, physical, social and cognitive activity, and management of cardiovascular risks was shown to be an effective model to promote brain health among older people. The aim of this qualitative study was to explore healthcare professionals' perceptions of facilitators and barriers to implementing this lifestyle programme into health care.

Introduction: Evidence on sex differences in the risk for dementia has been mixed. The goal was to assess sex differences in the development of dementia, and in the effects of a lifestyle intervention.

Methods: Two strategies were adopted, one using combined data from three large Nordic population-based cohort studies (n = 2289), adopting dementia as outcome, and 2-year multidomain lifestyle intervention (n = 1260), adopting cognitive change as outcome.

Gait speed is a measure of health and functioning. Physical and cognitive determinants of gait are amenable to interventions, but best practices remain unclear. We investigated the effects of a 12-month physical and cognitive training (PTCT) on gait speed, dual-task cost in gait speed, and executive functions (EFs) compared with physical training (PT) (ISRCTN52388040).

Background: frailty syndrome is common amongst older people. Low physical activity is part of frailty, but long-term prospective studies investigating leisure-time physical activity (LTPA) during the life course as a predictor of frailty are still warranted. The aim of this study is to investigate whether earlier life LTPA predicts frailty in older age.

Background: The oldest old is the fastest growing age group worldwide and the most prone to severe disability, especially in relation to loss of cognitive function. Improving our understanding of the predictors of cognitive, physical and psychosocial wellbeing among the oldest old can result in substantial benefits for the individuals and for the society as a whole. The Cardiovascular Risk Factors, Aging and Dementia (CAIDE) study investigated risk factors and determinants of cognitive impairment in a population-based longitudinal cohort, which was first examined between 1972 and 1992, when individuals were in their midlife, and re-assessed in 1998 and 2005-2009.

Background: Safe and stable walking is a complex process involving the interaction of neuromuscular, sensory and cognitive functions. As physical and cognitive functions deteriorate with ageing, training of both functions may have more beneficial effects on walking and falls prevention than either alone. This article describes the study design, recruitment strategies and interventions of the PASSWORD study investigating whether a combination of physical and cognitive training (PTCT) has greater effects on walking speed, dual-task cost in walking speed, fall incidence and executive functions compared to physical training (PT) alone among 70-85-year-old community-dwelling sedentary or at most moderately physically active men and women.

Objective: To investigate the associations between sleep disturbances in mid-life and late-life and late-life cognitive status.

Methods: In four population-based studies (three Swedish studies: H70 study, Kungsholmen Project (KP) and The Swedish Panel Study of Living Conditions of the Oldest Old (SWEOLD); and one Finnish study: Cardiovascular Risk Factors, Aging and Dementia (CAIDE)), participants provided self-reports on insomnia, nightmares and general sleep problems. Late-life cognitive status was measured by the Mini Mental State Exam (MMSE).

During the last few years, dementia prevention based on modifiable lifestyle factors has gained increasing attention. Cohort studies with follow-ups extending up to decades have identified several risk and protective factors, and very recently new randomized controlled trials with multidomain approach have provided promising evidence by showing that modifying simultaneously several risk factors, it is possible to maintain and improve cognitive capacity among older at-risk persons. Several lifestyle-based multidomain trials are under preparation or ongoing and to facilitate international collaboration and effective worldwide dementia prevention, the World Wide FINGERS interdisciplinary network (http://wwfingers.
