Short sleep duration has been associated with an increased risk of cognitive impairment and dementia. Short sleep is associated with elevated blood pressure, yet the combined insult of short sleep and hypertension on brain health remains unclear. We assessed whether the association of sleep duration with cognition and vascular brain injury was moderated by hypertensive… Continue reading Short #Sleep Duration and #Hypertension: A Double Hit for the #Brain

Blood #Pressure Variability and #Cognition in Black and White Older Adults Over 18 Years of Follow-up
Background and ObjectivesHypertension is a well-established cardiovascular risk factor for cognitive function. As blood pressure fluctuates because of aging-related changes, we examined the association between visit-to-visit blood pressure variability (BPV) and cognition in older adults. MethodsThis prospective observational cohort study included 4,770 individuals aged older than 65 years with repeated blood pressure assessment participating in… Continue reading Blood #Pressure Variability and #Cognition in Black and White Older Adults Over 18 Years of Follow-up
Associations of accelerometer-measured #physical activity, #sedentary behaviour, and #sleep with next-day #cognitive performance in older adults: a micro-longitudinal study
BackgroundPrevious studies suggest short-term cognitive benefits of physical activity occurring minutes to hours after exercise. Whether these benefits persist the following day and the role of sleep is unclear. We examined associations of accelerometer-assessed physical activity, sedentary behaviour, and sleep with next-day cognitive performance in older adults.MethodsBritish adults aged 50-83 years (N = 76) without evidence of… Continue reading Associations of accelerometer-measured #physical activity, #sedentary behaviour, and #sleep with next-day #cognitive performance in older adults: a micro-longitudinal study
#Cardiac Contributions to #Brain Health: A Scientific Statement From the American Heart Association
The burden of neurologic diseases, including stroke and dementia, is expected to grow substantially in the coming decades. Thus, achieving optimal brain health has been identified as a public health priority and a major challenge. Cardiovascular diseases are the leading cause of death and disability in the United States and around the world. Emerging evidence… Continue reading #Cardiac Contributions to #Brain Health: A Scientific Statement From the American Heart Association
Higher #Coffee Consumption Is Associated With Slower #Cognitive Decline and Less Cerebral Aβ-Amyloid Accumulation Over 126 Months: Data From the Australian Imaging, Biomarkers, and Lifestyle Study
AbstractBackground: Worldwide, coffee is one of the most popular beverages consumed. Several studies have suggested a protective role of coffee, including reduced risk of Alzheimer's disease (AD). However, there is limited longitudinal data from cohorts of older adults reporting associations of coffee intake with cognitive decline, in distinct domains, and investigating the neuropathological mechanisms underpinning any… Continue reading Higher #Coffee Consumption Is Associated With Slower #Cognitive Decline and Less Cerebral Aβ-Amyloid Accumulation Over 126 Months: Data From the Australian Imaging, Biomarkers, and Lifestyle Study
Long-Term Improvement in Hippocampal-Dependent #Learning Ability in Healthy, Aged Individuals Following High Intensity Interval #Training
AbstractPhysical exercise may reduce dementia risk in aging, but varying reports on its effectiveness make it challenging to ascribe what level of exercise will have significant longer-term effects on important functions such as hippocampal-based learning and memory. This study compared the effect of three different 6-month exercise regimens on hippocampal-dependent cognition in healthy, elderly individuals.… Continue reading Long-Term Improvement in Hippocampal-Dependent #Learning Ability in Healthy, Aged Individuals Following High Intensity Interval #Training
#Sleep duration, chronotype, #health and lifestyle factors affect cognition: a UK Biobank cross-sectional study
Objective To explore the nuanced relationship between sleep patterns, chronotype, quality and the influence of health and lifestyle factors on cognitive performance.Design, setting, participants This cross-sectional analysis used ordinary least squares regression within the UK Biobank database, assessing 26 820 participants aged 53–86 years, categorised into two cohorts: Cohort 1 (10 067 participants, 56% female; completed all four… Continue reading #Sleep duration, chronotype, #health and lifestyle factors affect cognition: a UK Biobank cross-sectional study
Effect of #gut #microbiome modulation on #muscle function and #cognition: the PROMOTe randomised controlled trial
Studies suggest that inducing gut microbiota changes may alter both muscle physiology and cognitive behaviour. Gut microbiota may play a role in both anabolic resistance of older muscle, and cognition. In this placebo controlled double blinded randomised controlled trial of 36 twin pairs (72 individuals), aged ≥60, each twin pair are block randomised to receive… Continue reading Effect of #gut #microbiome modulation on #muscle function and #cognition: the PROMOTe randomised controlled trial
The relationship between playing #musical instruments and #cognitive trajectories: Analysis from a UK ageing cohort
The accumulation of age-associated cognitive deficits can lead to Mild Cognitive Impairment (MCI) and dementia. This is a major public health issue for the modern ageing population, as it impairs health, independence and overall quality of life. Keeping the brain active during life has been associated with an increased cognitive reserve, therefore reducing the risk… Continue reading The relationship between playing #musical instruments and #cognitive trajectories: Analysis from a UK ageing cohort
