We evaluated the influence of age on the association between sex and the incidence of stroke or transient ischemic attack (TIA) using a population-based cohort from Ontario, Canada. Methods: We followed a cohort of adults (≥18 years) without prior stroke from January 1, 2003 (cohort start date) to March 31, 2018, to identify incident events.… Continue reading #Stroke Incidence by Sex Across the Lifespan

Increased Risk of #Parkinson’s Disease in Patients With #Schizophrenia Spectrum Disorders
PD comorbid with schizophrenia has been considered rare because these diseases associate with opposite alterations in the brain dopamine system. The objective of this study was to investigate the risk of PD after a diagnosis of a schizophrenia spectrum disorder. Methods Regionally, this was a retrospective record‐based case–control study. The cohort included 3045 PD patients… Continue reading Increased Risk of #Parkinson’s Disease in Patients With #Schizophrenia Spectrum Disorders
A neurotransmitter produced by #gut bacteria modulates host sensory #behaviour
Animals coexist in commensal, pathogenic or mutualistic relationships with complex communities of diverse organisms, including microorganisms. Some bacteria produce bioactive neurotransmitters that have previously been proposed to modulate nervous system activity and behaviours of their hosts. However, the mechanistic basis of this microbiota–brain signalling and its physiological relevance are largely unknown. Here we show that… Continue reading A neurotransmitter produced by #gut bacteria modulates host sensory #behaviour
Relationship between afternoon #napping and #cognitive function in the ageing Chinese population
Several studies have shown that afternoon napping promotes cognitive function in the elderly; on the other hand, some studies have shown opposite results. This current study further examined the relationship between afternoon napping and cognitive function in the ageing Chinese population. Methods A total of 2214 elderly were included (napping group: n=1534; non-napping group: n=680).… Continue reading Relationship between afternoon #napping and #cognitive function in the ageing Chinese population
The effects of #alcohol and #cannabis use on the cortical thickness of #cognitive control and salience brain networks in emerging adulthood: a cotwin control study
Background Impairments in inhibitory control and its underlying brain networks (control/salience areas) are associated with substance misuse. Research often assumes a causal substance exposure effect on brain structure. This assumption remains largely untested and other factors (e.g., familial risk) may confound exposure effects. We leveraged a genetically-informative sample of 24-year-old twins and a quasi-experimental cotwin… Continue reading The effects of #alcohol and #cannabis use on the cortical thickness of #cognitive control and salience brain networks in emerging adulthood: a cotwin control study
State-dependent responses to intracranial brain stimulation in a patient with #depression
Deep brain stimulation is a promising treatment for severe depression, but lack of efficacy in randomized trials raises questions regarding anatomical targeting. We implanted multi-site intracranial electrodes in a severely depressed patient and systematically assessed the acute response to focal electrical neuromodulation. We found an elaborate repertoire of distinctive emotional responses that were rapid in… Continue reading State-dependent responses to intracranial brain stimulation in a patient with #depression
6-month consequences of #COVID-19 in patients discharged from hospital: a cohort study
The long-term health consequences of COVID-19 remain largely unclear. The aim of this study was to describe the long-term health consequences of patients with COVID-19 who have been discharged from hospital and investigate the associated risk factors, in particular disease severity.. ..In total, 1733 of 2469 discharged patients with COVID-19 were enrolled after 736 were… Continue reading 6-month consequences of #COVID-19 in patients discharged from hospital: a cohort study
Clinical Outcomes Associated With Left #Atrial Appendage Occlusion Versus Direct Oral #Anticoagulation in Atrial #Fibrillation
This study sought to investigate clinical outcomes associated with left atrial appendage occlusion (LAAO) versus direct oral anticoagulants (DOACs) in patients with high-risk atrial fibrillation (AF).. ..Patients with AF enrolled in the Amulet Observational Registry (n = 1,088) who had successful LAAO with the Amplatzer Amulet device (n = 1,078) were compared with a propensity… Continue reading Clinical Outcomes Associated With Left #Atrial Appendage Occlusion Versus Direct Oral #Anticoagulation in Atrial #Fibrillation
#Depression and increased risk of #Alzheimer’s #dementia: longitudinal analyses of modifiable risk and sex-related factors.
Highlights •We investigated whether recent and/or remote depression was associated with increased risk of Alzheimer's Dementia (AD) and whether this risk differed between men and women. •Recent depression was independently associated with increased risk of incident AD while remote depression was not. Recent depression was predictive of AD development in females, but not in males,… Continue reading #Depression and increased risk of #Alzheimer’s #dementia: longitudinal analyses of modifiable risk and sex-related factors.
