Association of Daily Step Count and Intensity With Incident Dementia in 78 430 Adults Living in the UK

Key PointsQuestion  Is there a dose-response association of daily step count and intensity with incidence of all-cause dementia among adults living in the UK?Findings  This cohort study of adults assessed with wrist-worn accelerometers found that accruing more steps per day was associated with steady declines in dementia incidence risk, up to 9800 steps per day, beyond which… Continue reading Association of Daily Step Count and Intensity With Incident Dementia in 78 430 Adults Living in the UK

Tourism as a dementia treatment based on positive psychology

AbstractNo research in tourism or medicine has addressed the potential relationship between travel and the medical treatment of dementia. Given tourism's increasingly important role in society, a cross-disciplinary team of tourism and dementia experts provide insight into the potential benefits of tourism for individuals with dementia. This conceptual effort critically reviews the tourism and dementia… Continue reading Tourism as a dementia treatment based on positive psychology

Vitamin D and brain health: an observational and Mendelian randomization study

BackgroundHigher vitamin D status has been suggested to have beneficial effects on the brain. ObjectivesTo investigate the association between 25-hydroxyvitamin D [25(OH)D], neuroimaging features, and the risk of dementia and stroke. MethodsWe used prospective data from the UK Biobank (37–73 y at baseline) to examine the association between 25(OH)D concentrations with neuroimaging outcomes (N =… Continue reading Vitamin D and brain health: an observational and Mendelian randomization study

Stress-induced protein disaggregation in the endoplasmic reticulum catalysed by BiP

Protein synthesis is supported by cellular machineries that ensure polypeptides fold to their native conformation, whilst eliminating misfolded, aggregation prone species. Protein aggregation underlies pathologies including neurodegeneration. Aggregates’ formation is antagonised by molecular chaperones, with cytoplasmic machinery resolving insoluble protein aggregates. However, it is unknown whether an analogous disaggregation system exists in the Endoplasmic Reticulum… Continue reading Stress-induced protein disaggregation in the endoplasmic reticulum catalysed by BiP

Association of Serum Antioxidant Vitamins and Carotenoids With Incident Alzheimer Disease and All-Cause Dementia Among US Adults

Background. Serum antioxidant vitamins and carotenoids may protect against neurodegeneration with age. We examined associations of these nutritional biomarkers with incident all-cause and AD dementia among U.S. middle-aged and older adults. Methods. Using data from the third National health and Nutrition Examination Surveys (1988-1994), linked with Centers for Medicare and Medicaid-Medicare follow-up data, we tested… Continue reading Association of Serum Antioxidant Vitamins and Carotenoids With Incident Alzheimer Disease and All-Cause Dementia Among US Adults

Projecting prevalence of frailty and dementia and the economic cost of care in Japan from 2016 to 2043: a microsimulation modelling study

Dementia and frailty often accompany one another in older age, requiring complex care and resources. Available projections provide little information on their joint impact on future health-care need from different segments of society and the associated costs. Using a newly developed microsimulation model, we forecast this situation in Japan as its population ages and decreases… Continue reading Projecting prevalence of frailty and dementia and the economic cost of care in Japan from 2016 to 2043: a microsimulation modelling study

Role of Cardiovascular Risk Factors on the Association Between Physical Activity and Brain Integrity Markers in Older Adults

Objective: Physical activity has been associated with a decreased risk for dementia, but the mechanisms underlying this association remain to be determined. Our objective was to assess whether cardiovascular risk factors mediate the association between physical activity and brain integrity markers in older adults. Methods: Participants from the Age-Well study underwent, at baseline, a physical… Continue reading Role of Cardiovascular Risk Factors on the Association Between Physical Activity and Brain Integrity Markers in Older Adults

Time Trends in Incidence of Reported Memory Concerns and Cognitive Decline: A Cohort Study in UK Primary Care

Purpose: To investigate time trends in incidence of recorded memory concerns (MC) and cognitive decline (CD) in a UK older population presenting to primary care with no prior diagnosis of dementia. To determine the risk of developing dementia in people with recorded memory concern and cognitive decline.Patients and methods: We included individuals aged 65– 99… Continue reading Time Trends in Incidence of Reported Memory Concerns and Cognitive Decline: A Cohort Study in UK Primary Care

Association between lithium use and the incidence of dementia and its subtypes: A retrospective cohort study

BackgroundDementia is the leading cause of death in elderly Western populations. Preventative interventions that could delay dementia onset even modestly would provide a major public health impact. There are no disease-modifying treatments currently available. Lithium has been proposed as a potential treatment. We assessed the association between lithium use and the incidence of dementia and… Continue reading Association between lithium use and the incidence of dementia and its subtypes: A retrospective cohort study
