AbstractAbdominal fat is increasingly linked to brain health. A total of 10,001 healthy participants were scanned on 1.5T MRI with a short whole-body MR imaging protocol. Deep learning with FastSurfer segmented 96 brain regions. Separate models segmented visceral and subcutaneous abdominal fat. Regression analyses of abdominal fat types and normalized brain volumes were evaluated, controlling… Continue reading Visceral and Subcutaneous #Abdominal #Fat Predict #Brain Volume Loss at Midlife in 10,001 Individuals

The Gut-Brain Axis: Unveiling the Microbiome’s Role in Cognitive Development and Brain Health
A Complex Communication Highway In the intricate network of the human body, a fascinating unsuspected connection is being unraveled—one that links the gut and the brain in ways we never imagined! This connection, known as the Gut-Brain Axis, is revealing a whole new dimension to the critical role played by the microbiome in the development… Continue reading The Gut-Brain Axis: Unveiling the Microbiome’s Role in Cognitive Development and Brain Health
Effect of apolipoprotein genotype and #educational attainment on #cognitive function in autosomal dominant #Alzheimer’s disease
Autosomal dominant Alzheimer’s disease (ADAD) is genetically determined, but variability in age of symptom onset suggests additional factors may influence cognitive trajectories. Although apolipoprotein E (APOE) genotype and educational attainment both influence dementia onset in sporadic AD, evidence for these effects in ADAD is limited. To investigate the effects of APOE and educational attainment on age-related cognitive… Continue reading Effect of apolipoprotein genotype and #educational attainment on #cognitive function in autosomal dominant #Alzheimer’s disease
Effects of adult #education on #cognitive function and risk of #dementia in older adults: a longitudinal analysis
Introduction: Mid/late-life cognitive activities are associated with a lower rate of subsequent cognitive decline and lower subsequent dementia risk over time.Methods: In this study, we investigated the association between adult education class participation and subsequent cognitive decline and dementia risk over time after adjusting for baseline cognitive function and genetic risk of dementia, correcting for several potential… Continue reading Effects of adult #education on #cognitive function and risk of #dementia in older adults: a longitudinal analysis
Interaction of an α-synuclein epitope with HLA-DRB1∗15:01 triggers enteric features in mice reminiscent of prodromal #Parkinson’s disease
•α-syn32-46 immunization of HLA-DRB1∗15:01 mice triggers weight loss and constipation•α-syn32-46 immunizations induce inflammation and neuron loss in the gut•Depletion of CD4+, but not CD8+, T cells partially rescues enteric neural loss•Both α-syn32-46 and HLA-DRB1∗15:01 are critical for this model of prodromal PD SummaryEnteric symptoms are hallmarks of prodromal Parkinson’s disease (PD) that appear decades before the onset of motor… Continue reading Interaction of an α-synuclein epitope with HLA-DRB1∗15:01 triggers enteric features in mice reminiscent of prodromal #Parkinson’s disease
Higher working #memory capacity and distraction-resistance associated with strategy (not action) #game playing in younger adults, but #puzzle game playing in older adults
Superior attention and Working Memory (WM) have been reported for habitual action video gamers compared to other gamers or non-players. With an online experiment we measured visuo-spatial WM capacity and ability to ignore distraction, and participants listed the video games they played. Categorising the 209 young adult participants (18–30 years) according to the game type… Continue reading Higher working #memory capacity and distraction-resistance associated with strategy (not action) #game playing in younger adults, but #puzzle game playing in older adults
Speakers of different #languages remember #visual scenes differently
Language can have a powerful effect on how people experience events. Here, we examine how the languages people speak guide attention and influence what they remember from a visual scene. When hearing a word, listeners activate other similar-sounding words before settling on the correct target. We tested whether this linguistic coactivation during a visual search… Continue reading Speakers of different #languages remember #visual scenes differently
American #Football Play and #Parkinson Disease Among Men
Importance Parkinsonism and Parkinson disease (PD) are known to result from repetitive head impacts from boxing. Repetitive head impacts from American football may also be associated with increased risk of neurodegenerative pathologies that cause parkinsonism, yet in vivo research on the association between football play and PD is scarce and limited by small samples and equivocal… Continue reading American #Football Play and #Parkinson Disease Among Men
Regional, circuit and network heterogeneity of #brain abnormalities in #psychiatric disorders
The substantial individual heterogeneity that characterizes people with mental illness is often ignored by classical case–control research, which relies on group mean comparisons. Here we present a comprehensive, multiscale characterization of the heterogeneity of gray matter volume (GMV) differences in 1,294 cases diagnosed with one of six conditions (attention-deficit/hyperactivity disorder, autism spectrum disorder, bipolar disorder,… Continue reading Regional, circuit and network heterogeneity of #brain abnormalities in #psychiatric disorders
