Highlights•Whether daytime napping is causally associated with brain health remains elusive.•We studied the causal role of daytime napping on cognitive and neuroimaging outcomes.•We found a modest causal link between habitual napping and larger total brain volume. Daytime napping has been associated with cognitive function and brain health in observational studies. However, it remains elusive whether these associations… Continue reading Is there an association between daytime napping, cognitive function, and brain volume?

A history of repeated alcohol intoxication promotes cognitive impairment and gene expression signatures of disease progression in the 3xTg mouse model of Alzheimer’s disease
The impact of alcohol abuse on Alzheimer’s disease (AD) is poorly understood. Here, we show that the onset of neurocognitive impairment in a mouse model of AD is hastened by repeated alcohol intoxication through exposure to alcohol vapor, and we provide a comprehensive gene expression dataset of the prefrontal cortex by the single-nucleus RNA sequencing… Continue reading A history of repeated alcohol intoxication promotes cognitive impairment and gene expression signatures of disease progression in the 3xTg mouse model of Alzheimer’s disease
Increase in skeletal muscular adiposity and cognitive decline in a biracial cohort of older men and women
AbstractBackgroundObesity and loss of muscle mass are emerging as risk factors for dementia, but the role of adiposity infiltrating skeletal muscles is less clear. Skeletal muscle adiposity increases with older age and especially among Black women, a segment of the US population who is also at higher risk for dementia.MethodsIn 1634 adults (69–79 years, 48% women,… Continue reading Increase in skeletal muscular adiposity and cognitive decline in a biracial cohort of older men and women
Longer-term mixed nut consumption improves brain vascular function and memory: A randomized, controlled crossover trial in older adults
Nut consumption may reduce age-related cognitive decline, but underlying mechanisms are unclear ObjectiveTo investigate in older adults longer-term effects of mixed nut consumption on brain vascular function, which may underlie improvements in cognitive performance.MethodsTwenty-eight healthy individuals (age [mean ± SD]: 65 ± 3 years; BMI: 27.9 ± 2.3 kg/m2) were included in a randomized, single-blinded, cross-over trial with a 16-week intervention (60 g/d… Continue reading Longer-term mixed nut consumption improves brain vascular function and memory: A randomized, controlled crossover trial in older adults
Association Between Acute Myocardial Infarction and Cognition
Importance The magnitude of cognitive change after incident myocardial infarction (MI) is unclear.Objective To assess whether incident MI is associated with changes in cognitive function after adjusting for pre-MI cognitive trajectories.Design, Setting, and Participants This cohort study included adults without MI, dementia, or stroke and with complete covariates from the following US population-based cohort studies conducted from 1971… Continue reading Association Between Acute Myocardial Infarction and Cognition
The third Intensive Care Bundle with Blood Pressure Reduction in Acute Cerebral Haemorrhage Trial (INTERACT3): an international, stepped wedge cluster randomised controlled trial
Early control of elevated blood pressure is the most promising treatment for acute intracerebral haemorrhage. We aimed to establish whether implementing a goal-directed care bundle incorporating protocols for early intensive blood pressure lowering and management algorithms for hyperglycaemia, pyrexia, and abnormal anticoagulation, implemented in a hospital setting, could improve outcomes for patients with acute spontaneous… Continue reading The third Intensive Care Bundle with Blood Pressure Reduction in Acute Cerebral Haemorrhage Trial (INTERACT3): an international, stepped wedge cluster randomised controlled trial
Erectile Function, Sexual Satisfaction, and Cognitive Decline in Men From Midlife to Older Adulthood
Background and ObjectivesVascular theories of cognitive aging have focused on macrovascular changes and cognitive decline. However, according to the artery-size hypothesis, microvascular changes, such as those that underlie changes in erectile function, may also play an important role in contributing to cognitive decline. Thus, we examined associations between erectile function, sexual satisfaction, and cognition starting… Continue reading Erectile Function, Sexual Satisfaction, and Cognitive Decline in Men From Midlife to Older Adulthood
Isosorbide Mononitrate and Cilostazol Treatment in Patients With Symptomatic Cerebral Small Vessel Disease
Cerebral small vessel disease (cSVD) is a common cause of stroke (lacunar stroke), is the most common cause of vascular cognitive impairment, and impairs mobility and mood but has no specific treatment.Objective To test the feasibility, drug tolerability, safety, and effects of 1-year isosorbide mononitrate (ISMN) and cilostazol treatment on vascular, functional, and cognitive outcomes in… Continue reading Isosorbide Mononitrate and Cilostazol Treatment in Patients With Symptomatic Cerebral Small Vessel Disease
Dietary flavanols restore hippocampal-dependent memory in older adults with lower diet quality and habitual flavanol consumption
Dietary flavanols are food constituents found in certain fruits and vegetables that have been linked to cognitive aging. Previous studies suggested that consumption of dietary flavanols might specifically be linked to the hippocampal-dependent memory component of cognitive aging and that memory benefits of a flavanol intervention might depend on habitual diet quality. Here, we tested… Continue reading Dietary flavanols restore hippocampal-dependent memory in older adults with lower diet quality and habitual flavanol consumption
