PRAC recommends new measures to avoid #topiramate exposure in #pregnancy

Further restrictions on use; pregnancy prevention programme to be put in placeEMA’s safety committee (PRAC) recommends new measures to avoid exposure of children to topiramate-containing medicines in the womb, because the medicine may increase the risk of neurodevelopmental problems after exposure during pregnancy. Topiramate is already known to cause serious birth defects when used during… Continue reading PRAC recommends new measures to avoid #topiramate exposure in #pregnancy

Irisin reduces #amyloid-β by inducing the release of neprilysin from #astrocytes following downregulation of ERK-STAT3 signaling

A pathological hallmark of Alzheimer’s disease (AD) is the deposition of amyloid-β (Aβ) protein in the brain. Physical exercise has been shown to reduce Aβ burden in various AD mouse models, but the underlying mechanisms have not been elucidated. Irisin, an exercise-induced hormone, is the secreted form of fibronectin type-III-domain-containing 5 (FNDC5). Here, using a… Continue reading Irisin reduces #amyloid-β by inducing the release of neprilysin from #astrocytes following downregulation of ERK-STAT3 signaling

Visceral and Subcutaneous #Abdominal #Fat Predict #Brain Volume Loss at Midlife in 10,001 Individuals

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
