Background and ObjectivesConsumption of low- and no-calorie sweeteners (LNCSs) has been associated with adverse health outcomes. However, little is known about the association between consumption of LNCSs and cognition. The aim of this study was to investigate the association between consumption of LNCSs and cognitive decline.MethodsWe conducted a longitudinal observational study using data from civil… Continue reading Association Between Consumption of Low- and No-Calorie Artificial #Sweeteners and #Cognitive DeclineAn 8-Year Prospective Study

#Limbic gray matter increases in response to #cognitive-behavioral therapy in major #depressive disorder
Major depressive disorder (MDD) is related to volumetric decreases in (cortico-)limbic brain regions. In contrast to pharmacological and electroconvulsive therapy, little is known about the brain structural effects of psychotherapy and potential links to symptom improvements. In a naturalistic longitudinal study using structural magnetic resonance tomography, gray matter volume (GMV) and clinical measures were assessed… Continue reading #Limbic gray matter increases in response to #cognitive-behavioral therapy in major #depressive disorder
Association between dietary #copper intake and #cognitive function in American older adults: NHANES 2011–2014
This cross-sectional observational study examined the association between dietary copper intake and cognitive function in American older adults, using data from the 2011 to 2014 National Health and Nutrition Examination Survey (NHANES). Analyzing a total of 2420 participants, dietary copper intake was determined by averaging two 24-h dietary recalls, whereas cognitive function was assessed by… Continue reading Association between dietary #copper intake and #cognitive function in American older adults: NHANES 2011–2014
Your #Brain on ChatGPT: Accumulation of #Cognitive Debt when Using an #AI Assistant for Essay Writing Task
This study explores the neural and behavioral consequences of LLM-assisted essay writing. Participants were divided into three groups: LLM, Search Engine, and Brain-only (no tools). Each completed three sessions under the same condition. In a fourth session, LLM users were reassigned to Brain-only group (LLM-to-Brain), and Brain-only users were reassigned to LLM condition (Brain-to-LLM). A… Continue reading Your #Brain on ChatGPT: Accumulation of #Cognitive Debt when Using an #AI Assistant for Essay Writing Task
Increased #sedentary behavior is associated with #neurodegeneration and worse cognition in older adults over a 7-year period despite high levels of physical activity
INTRODUCTIONSedentary behavior may be a modifiable risk factor for Alzheimer's disease (AD). We examined how sedentary behavior relates to longitudinal brain structure and cognitive changes in older adults.METHODSVanderbilt Memory and Aging Project participants (n = 404) completed actigraphy (7 days), neuropsychological assessment, and 3T brain MRI over a 7-year period. Cross-sectional and longitudinal linear regressions… Continue reading Increased #sedentary behavior is associated with #neurodegeneration and worse cognition in older adults over a 7-year period despite high levels of physical activity
Association Between #Alcohol Consumption, #Cognitive Abilities, and Neuropathologic Changes
Background and ObjectivesHeavy alcohol consumption is a major global health concern linked to increased morbidity and mortality. However, the long-term impact of excessive alcohol consumption on cognitive abilities and dementia-related neuropathology is unclear. The aim of this study was to analyze the association between alcohol consumption and age-related neuropathologic outcomes in a population-based autopsy study.MethodsThis… Continue reading Association Between #Alcohol Consumption, #Cognitive Abilities, and Neuropathologic Changes
Association of #Diet and #Waist-to-Hip Ratio With Brain Connectivity and #Memory in #Aging
Importance Epidemiological studies suggest that lifestyle factors are associated with risk of dementia. However, few studies have examined the association of diet and waist to hip ratio (WHR) with hippocampus connectivity and cognitive health.Objective To ascertain how longitudinal changes in diet quality and WHR during midlife are associated with hippocampal connectivity and cognitive function in… Continue reading Association of #Diet and #Waist-to-Hip Ratio With Brain Connectivity and #Memory in #Aging
Short #Sleep Duration and #Hypertension: A Double Hit for the #Brain
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
