Number of #teeth and masticatory function are associated with #sarcopenia and #diabetes mellitus status among community-dwelling older adults: A Shimane CoHRE study

We aimed to examine the number of teeth and masticatory function as oral health indices and clarify their roles in the pathogenesis of sarcopenia and diabetes mellitus in community-dwelling older adults. Subjects and methodsThis cross-sectional study was conducted with 635 older adults in Ohnan, Shimane Prefecture, in rural Japan. The number of teeth and masticatory… Continue reading Number of #teeth and masticatory function are associated with #sarcopenia and #diabetes mellitus status among community-dwelling older adults: A Shimane CoHRE study

Consolidation of human #skill linked to waking hippocampo-neocortical replay

The introduction of rest intervals interspersed with practice strengthens wakeful consolidation of skill. The mechanisms by which the brain binds discrete action representations into consolidated, highly temporally-resolved skill sequences during waking rest are not known. To address this question, we recorded magnetoencephalography (MEG) during acquisition and rapid consolidation of a sequential motor skill. We report… Continue reading Consolidation of human #skill linked to waking hippocampo-neocortical replay

Reduced coupling between cerebrospinal fluid flow and global #brain activity is linked to #Alzheimer disease–related pathology

The glymphatic system plays an important role in clearing the amyloid-β (Aβ) and tau proteins that are closely linked to Alzheimer disease (AD) pathology. Glymphatic clearance, as well as Aβ accumulation, is highly dependent on sleep, but the sleep-dependent driving forces behind cerebrospinal fluid (CSF) movements essential to the glymphatic flux remain largely unclear. Recent… Continue reading Reduced coupling between cerebrospinal fluid flow and global #brain activity is linked to #Alzheimer disease–related pathology

A multicentre validation study of the diagnostic value of plasma #neurofilament light

Increased cerebrospinal fluid neurofilament light (NfL) is a recognized biomarker for neurodegeneration that can also be assessed in blood. Here, we investigate plasma NfL as a marker of neurodegeneration in 13 neurodegenerative disorders, Down syndrome, depression and cognitively unimpaired controls from two multicenter cohorts: King’s College London (n = 805) and the Swedish BioFINDER study (n = 1,464). Plasma… Continue reading A multicentre validation study of the diagnostic value of plasma #neurofilament light

Predicting #language treatment response in bilingual #aphasia using neural network-based patient models

Predicting language therapy outcomes in bilinguals with aphasia (BWA) remains challenging due to the multiple pre- and poststroke factors that determine the deficits and recovery of their two languages. Computational models that simulate language impairment and treatment outcomes in BWA can help predict therapy response and identify the optimal language for treatment. Here we used… Continue reading Predicting #language treatment response in bilingual #aphasia using neural network-based patient models

#Sleep difficulties, incident #dementia and all-cause mortality among older adults across 8 years: Findings from the National Health and Aging Trends Study

Sleep difficulties have been implicated in the development and progression of dementia and in all-cause mortality. This study examines the relationship between sleep difficulties, incident dementia and all-cause mortality over 8 years of follow-up among a nationally representative sample of older (≥65 years) adults in the United States. We used data collected from the National… Continue reading #Sleep difficulties, incident #dementia and all-cause mortality among older adults across 8 years: Findings from the National Health and Aging Trends Study

Randomized Manipulation of Early #Cognitive Experience Impacts Adult Brain Structure

Does early exposure to cognitive and linguistic stimulation impact brain structure? Or do genetic predispositions account for the co-occurrence of certain neuroanatomical phenotypes and a tendency to engage children in cognitively stimulating activities? Low socioeconomic status infants were randomized to either 5 years of cognitively and linguistically stimulating center-based care or a comparison condition. The… Continue reading Randomized Manipulation of Early #Cognitive Experience Impacts Adult Brain Structure

Causal Effect of #Tooth Loss on Functional Capacity in Older Adults in England: A Natural Experiment

Background/ObjectivesTooth loss is associated with reduced functional capacity, but so far, there is no relevant causal evidence reported. We investigated the causal effect of tooth loss on the instrumental activities of daily living (IADL) among older adults in England. DesignNatural experiment study with instrumental variable analysis. SettingThe English Longitudinal Study of Aging (ELSA) combined with… Continue reading Causal Effect of #Tooth Loss on Functional Capacity in Older Adults in England: A Natural Experiment

Increased #Risk of Stroke in Patients With #Obsessive-Compulsive Disorder: A Nationwide Longitudinal Study

Patients with obsessive-compulsive disorder (OCD) tend to be comorbid with stroke-related risk factors, including obesity, hypertension, and diabetes. However, the temporal association between OCD and subsequent stroke risk is unclear. Methods:Using data collected between 2001 and 2010 by Taiwan’s National Health Insurance Research Database, 28 064 adult patients with OCD (International Classification of Diseases, Ninth… Continue reading Increased #Risk of Stroke in Patients With #Obsessive-Compulsive Disorder: A Nationwide Longitudinal Study
