#Meat consumption and risk of incident #dementia: cohort study of 493,888 UK Biobank participants

Worldwide, the prevalence of dementia is increasing and diet as a modifiable factor could play a role. Meat consumption has been cross-sectionally associated with dementia risk, but specific amounts and types related to risk of incident dementia remain poorly understood. Objective We aimed to investigate associations between meat consumption and risk of incident dementia in the UK Biobank cohort. Methods Meat consumption was estimated using … Continue reading #Meat consumption and risk of incident #dementia: cohort study of 493,888 UK Biobank participants

#Olfactory dysfunction predicts the development of #dementia in older patients with type 2 #diabetes

Olfactory dysfunction is associated with the transition from normal cognition to dementia in persons without type 2 diabetes. This study aimed to investigate whether olfactory dysfunction could be an early marker of future dementia in older patients with type 2 diabetes. Methods This exploratory study included 151 older Japanese outpatients with type 2 diabetes who did not have a diagnosis of probable dementia at baseline. … Continue reading #Olfactory dysfunction predicts the development of #dementia in older patients with type 2 #diabetes

Prevalence of Central Nervous System–Active Polypharmacy Among Older Adults With #Dementia in the US

Community-dwelling older adults with dementia have a high prevalence of psychotropic and opioid use. In these patients, central nervous system (CNS)–active polypharmacy may increase the risk for impaired cognition, fall-related injury, and death. Objective To determine the extent of CNS-active polypharmacy among community-dwelling older adults with dementia in the US. Design, Setting, and Participants Cross-sectional analysis of all community-dwelling older adults with dementia (identified by … Continue reading Prevalence of Central Nervous System–Active Polypharmacy Among Older Adults With #Dementia in the US

Clinical and Biological Correlates of White Matter Hyperintensities in Patients with #Behavioral-variant Frontotemporal #Dementia and #Alzheimer Disease

To test the hypothesis that white matter hyperintensities (WMH) in behavioral-variant frontotemporal dementia (bvFTD) and Alzheimer disease (AD) are associated with disease variables such as disease severity, cortical atrophy and cognition, we conducted a cross-sectional brain MRI study with volumetric and voxel-wise analyses. Methods: 129 patients (64 bvFTD, 65 AD) and 66 controls underwent high-resolution brain MRI, clinical and neuropsychological examination. Genetic screening was conducted … Continue reading Clinical and Biological Correlates of White Matter Hyperintensities in Patients with #Behavioral-variant Frontotemporal #Dementia and #Alzheimer Disease

#Physical activity may not be associated with long‐term risk of #dementia and #Alzheimer’s disease

While it is well established that physical activity is associated with reduced risk of vascular and nonvascular outcomes as well as mortality, evidence on the association between physical activity and dementia is inconsistent. We aimed to assess the associations of physical activity with the risk of dementia and Alzheimer’s disease (AD). Material and methods We analysed data on 2394 apparently healthy men with good baseline … Continue reading #Physical activity may not be associated with long‐term risk of #dementia and #Alzheimer’s disease

#Depression and increased risk of #Alzheimer’s #dementia: longitudinal analyses of modifiable risk and sex-related factors.

Highlights •We investigated whether recent and/or remote depression was associated with increased risk of Alzheimer’s Dementia (AD) and whether this risk differed between men and women. •Recent depression was independently associated with increased risk of incident AD while remote depression was not. Recent depression was predictive of AD development in females, but not in males, while sex did not moderate recent depression-associated risk of developing … Continue reading #Depression and increased risk of #Alzheimer’s #dementia: longitudinal analyses of modifiable risk and sex-related factors.

#Cardiovascular health metrics from mid- to late-life and risk of #dementia: A population-based cohort study in Finland

Very few studies have explored the patterns of cardiovascular health (CVH) metrics in midlife and late life in relation to risk of dementia. We examined the associations of composite CVH metrics from midlife to late life with risk of incident dementia. This cohort study included 1,449 participants from the Finnish Cardiovascular Risk Factors, Aging, and Dementia (CAIDE) study, who were followed from midlife (baseline from1972 … Continue reading #Cardiovascular health metrics from mid- to late-life and risk of #dementia: A population-based cohort study in Finland

#Apathy in presymptomatic genetic frontotemporal #dementia predicts cognitive decline and is driven by structural brain changes

Apathy adversely affects prognosis and survival of patients with frontotemporal dementia (FTD). We test whether apathy develops in presymptomatic genetic FTD, and is associated with cognitive decline and brain atrophy.. ..Results Apathy severity increased over time in presymptomatic carriers, but not in non‐carriers. In presymptomatic carriers, baseline apathy predicted cognitive decline over two years, but not vice versa. Apathy progression was associated with baseline low … Continue reading #Apathy in presymptomatic genetic frontotemporal #dementia predicts cognitive decline and is driven by structural brain changes

#Dementia and the risk of death in elderly patients with #COVID‐19 infection: Systematic review and meta‐analysis

The COVID‐19 infection represents a global public health emergency worldwide. Several risk factors have been associated with a poor prognosis among COVID‐19 patients. We aimed to perform a systemic review and meta‐analysis to evaluate the mortality risk in elderly patients with dementia and COVID‐19 infection.. ..A total of 233 articles were retrieved; 158 were excluded for not meeting the inclusion criteria, leaving 75 articles to … Continue reading #Dementia and the risk of death in elderly patients with #COVID‐19 infection: Systematic review and meta‐analysis

Associations of #BMI and Serum #Urate with Developing #Dementia: A Prospective Cohort Study

Recent studies suggested that higher BMI and serum urate levels were associated with lower risk of developing dementia. However, these reverse relationships remain controversial, and whether serum urate and BMI confound each other is not well established.. ..During a median of 8.1 years of follow-up, a total of 2138 participants developed dementia. People who were underweight had an increased risk of dementia (hazard ratio [HR] … Continue reading Associations of #BMI and Serum #Urate with Developing #Dementia: A Prospective Cohort Study

Post-traumatic stress disorder as a risk factor for #dementia: systematic review and meta-analysis

Post-traumatic stress disorder (PTSD) has been identified as a potential risk factor for developing dementia. There are currently, however, no meta-analyses quantifying this risk.. ..PTSD was associated with a significant risk for all-cause dementia: pooled hazard ratio HR = 1.61 (95% CI 1.43–1.81, I2= 85.8%, P < 0.001; n = 1 693 678; 8 studies).
