Sleep is essential for optimal functioning and health. Interconnected to multiple biological, psychological, and socio-environmental factors (i.e., biopsychosocial factors), the multidimensional nature of sleep is rarely capitalized on in research. Here, we deployed a data-driven approach to identify sleep-biopsychosocial profiles that linked self-reported sleep patterns to inter-individual variability in health, cognition, and lifestyle factors in… Continue reading Identification of five #sleep -biopsychosocial profiles with specific neural signatures linking sleep variability with #health, cognition, and lifestyle factors

Development and validation of blood-based diagnostic biomarkers for #Myalgic #Encephalomyelitis/#Chronic Fatigue Syndrome (ME/CFS) using EpiSwitch® 3-dimensional genomic regulatory immuno-genetic profiling
Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a debilitating, multifactorial disorder characterised by profound fatigue, post-exertional malaise, cognitive impairments, and autonomic dysfunction. Despite its significant impact on quality of life, ME/CFS lacks definitive diagnostic biomarkers, complicating diagnosis and management. Recent evidence highlights potential blood tests for ME/CFS biomarkers in immunological, genetic, metabolic, and bioenergetic domains. Chromosome… Continue reading Development and validation of blood-based diagnostic biomarkers for #Myalgic #Encephalomyelitis/#Chronic Fatigue Syndrome (ME/CFS) using EpiSwitch® 3-dimensional genomic regulatory immuno-genetic profiling
Unlocking deep #relaxation: the power of #rhythmic #breathing on brain rhythms
The pandemic has exacerbated mental health issues across the world. The limited availability of mental health professionals is preventing many from seeking help, which highlights the need for easily available mental health care routines like yoga, breathing, and meditation. A breath-based meditation technique known as Sudarshan Kriya #Yoga (SKY) harnesses the power of breath to… Continue reading Unlocking deep #relaxation: the power of #rhythmic #breathing on brain rhythms
Risk markers for sudden unexpected #death in #epilepsy: an observational, prospective, multicentre cohort study
Sudden unexpected death in epilepsy (SUDEP) is the leading cause of epilepsy-related mortality. Generalised—particularly nocturnal—convulsive seizures, longstanding epilepsy, and solitary living have been identified retrospectively as risk factors. No definitive electroclinical biomarkers have been prospectively ascertained. This study aimed to identify SUDEP risk markers using multimodality data with long-term follow-up.MethodsThis prospective, multicentre, observational cohort study,… Continue reading Risk markers for sudden unexpected #death in #epilepsy: an observational, prospective, multicentre cohort study
Associations of Chronic #Insomnia, Longitudinal #Cognitive Outcomes, Amyloid-PET, and White Matter Changes in Cognitively Normal Older Adults
The relationship between insomnia and cognitive decline is poorly understood. We investigated associations between chronic insomnia, longitudinal cognitive outcomes, and brain health in older adults.MethodsFrom the population-based Mayo Clinic Study of Aging, we identified cognitively unimpaired older adults with or without a diagnosis of chronic insomnia who underwent annual neuropsychological assessments (z-scored global cognitive scores… Continue reading Associations of Chronic #Insomnia, Longitudinal #Cognitive Outcomes, Amyloid-PET, and White Matter Changes in Cognitively Normal Older Adults
Structural brain improvements following individually tailored serious #exergame-based training in mild #neurocognitive disorders: exploratory randomized controlled trial
IntroductionExergame-based training is emerging as the most effective exercise modality for improving cognition, yet its neural correlates remain largely unexplored. This study explored gray matter (GM) and white matter (WM) changes following the addition of ‘Brain-IT’ training to usual care in mild neurocognitive disorder (mNCD) and their associations with cognitive performance changes.MethodsWe included 41 participants… Continue reading Structural brain improvements following individually tailored serious #exergame-based training in mild #neurocognitive disorders: exploratory randomized controlled trial
A passive and objective measure of recognition memory in mild #cognitive #impairment using Fastball #memory assessment
As viable pharmacotherapies and blood biomarkers emerge for dementia treatment and screening, there remains a great need for accurate, sensitive biomarkers of cognitive function. We have previously demonstrated that Fastball, a new Electroencephalography (EEG) method for the passive and objective measurement of recognition memory that requires no behavioural memory response or task comprehension, is sensitive… Continue reading A passive and objective measure of recognition memory in mild #cognitive #impairment using Fastball #memory assessment
Association Between Consumption of Low- and No-Calorie Artificial #Sweeteners and #Cognitive DeclineAn 8-Year Prospective Study
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
#Retinal vascular dysfunction in the Mthfr677C>T mouse model of #cerebrovascular disease
INTRODUCTIONInvestigations of retinal biomarkers for #Alzheimer's disease (AD) and AD and related dementias (ADRD), has increased significantly. We examine retinal vascular health in a mouse containing the ADRD risk variant Mthfr677C>T to determine if changes in retina mirror similar changes in cerebrovasculature.METHODSMorphology and function of retinal vasculature and neurons were assessed using in vivo imaging,… Continue reading #Retinal vascular dysfunction in the Mthfr677C>T mouse model of #cerebrovascular disease
