Epidemiological data link traffic-related air pollution (TRAP) to increased risk of Alzheimer’s disease (AD). Preclinical data corroborating this association are largely from studies of male animals exposed acutely or subchronically to high levels of isolated fractions of TRAP. What remains unclear is whether chronic exposure to ambient TRAP modifies AD risk and the influence of… Continue reading The Effects of Chronic Exposure to Ambient #Traffic-Related Air #Pollution on #Alzheimer’s Disease Phenotypes in Wildtype and Genetically Predisposed Male and Female Rats

Effects of #music participation for mild #cognitive impairment and #dementia: A systematic review and meta-analysis
To examine randomized controlled trials with active music-making interventions, in which older adults with probable mild cognitive impairment (MCI) or dementia physically participate in music, and their effects on cognitive functioning, emotional well-being, and social engagement. Participating in music-making is engaging and has shown diverse benefits. Additionally, this review categorized the music activities of each… Continue reading Effects of #music participation for mild #cognitive impairment and #dementia: A systematic review and meta-analysis
The Effects of Aerobic #Exercise on Serum Biomarkers of Neuroplasticity and Brain Repair in #Stroke: A Systematic Review
To provide a novel overview of the literature and to summarise the evidence for the effects of aerobic exercise (AE) on serum biomarkers neuroplasticity and brain repair in stroke survivors. Data SourceWe conducted a systematic review and searched MEDLINE, EMBASE and Cochrane CENTRAL using terms related to AE, neuroplasticity, brain repair, and stroke. Study SelectionTitles,… Continue reading The Effects of Aerobic #Exercise on Serum Biomarkers of Neuroplasticity and Brain Repair in #Stroke: A Systematic Review
Association of #Mitochondrial Biogenesis With Variable Penetrance of #Schizophrenia
Discovery of mechanisms that underlie variable penetrance for neuropsychiatric illness in the context of genetic variants that carry elevated risk can advance novel treatment approaches for these disorders. Objective To test the hypothesis that mitochondrial compensation is associated with the variable penetrance of schizophrenia in the 22q11.2 deletion syndrome (22q11DS). Design, Setting, and Participants This… Continue reading Association of #Mitochondrial Biogenesis With Variable Penetrance of #Schizophrenia
Associations of #cognitive performance with #cardiovascular magnetic resonance phenotypes in the UK Biobank
Existing evidence suggests links between brain and cardiovascular health. We investigated associations between cognitive performance and cardiovascular magnetic resonance (CMR) phenotypes in the UK Biobank, considering a range of potential confounders. Methods and resultsWe studied 29 763 participants with CMR and cognitive testing, specifically, fluid intelligence (FI, 13 verbal-numeric reasoning questions), and reaction time (RT, a… Continue reading Associations of #cognitive performance with #cardiovascular magnetic resonance phenotypes in the UK Biobank
#Antihypertensives and #Statin Therapy for Primary #Stroke Prevention
The HOPE-3 trial (Heart Outcomes Prevention Evaluation–3) found that antihypertensive therapy combined with a statin reduced first stroke among people at intermediate cardiovascular risk. We report secondary analyses of stroke outcomes by stroke subtype, predictors, treatment effects in key subgroups. Methods:Using a 2-by-2 factorial design, 12 705 participants from 21 countries with vascular risk factors… Continue reading #Antihypertensives and #Statin Therapy for Primary #Stroke Prevention
The #overfitted brain: #Dreams evolved to assist generalization
Dreaming remains a mystery to neuroscience. While various hypotheses of why brains evolved nightly dreaming have been put forward, many of these are contradicted by the sparse, hallucinatory, and narrative nature of dreams, a nature that seems to lack any particular function. Recently, research on artificial neural networks has shown that during learning, such networks… Continue reading The #overfitted brain: #Dreams evolved to assist generalization
#Smoking is associated with impaired verbal learning and #memory performance in women more than men
Vascular contributions to cognitive impairment and dementia (VCID) include structural and functional blood vessel injuries linked to poor neurocognitive outcomes. Smoking might indirectly increase the likelihood of cognitive impairment by exacerbating vascular disease risks. Sex disparities in VCID have been reported, however, few studies have assessed the sex-specific relationships between smoking and memory performance and… Continue reading #Smoking is associated with impaired verbal learning and #memory performance in women more than men
#Sarcopenia is independently associated with #parietal atrophy in older adults
Highlights•Sarcopenia was common in old adults living in a retirement community (46.1%). •Sarcopenia had moderate-severe global cortical, parietal and medial temporal atrophy. •Sarcopenia is significantly associated with parietal atrophy in older adults. •Age had a significant relationship with global cortical and medial temporal atrophy. AbstractIntroductionAs populations age, sarcopenia becomes a major health problem among adults… Continue reading #Sarcopenia is independently associated with #parietal atrophy in older adults
