Cavernous angiomas (CA) are common vascular anomalies causing brain hemorrhage. Based on mouse studies, roles of gram-negative bacteria and altered intestinal homeostasis have been implicated in CA pathogenesis, and pilot study had suggested potential microbiome differences between non-CA and CA individuals based on 16S rRNA gene sequencing. We here assess microbiome differences in a larger… Continue reading Permissive microbiome characterizes human subjects with a neurovascular disease cavernous angioma

Repetitive negative #thinking is associated with #amyloid, tau, and cognitive decline
The Cognitive Debt hypothesis proposes that repetitive negative thinking (RNT), a modifiable process common to many psychological risk factors for Alzheimer's disease (AD) may itself increase risk. We sought to empirically examine relationships between RNT and markers of AD, compared with anxiety and depression symptoms. ..RNT was associated with decline in global cognition (P =… Continue reading Repetitive negative #thinking is associated with #amyloid, tau, and cognitive decline
Daily listening to Mozart reduces seizures in individuals with epilepsy: A randomized control study
Epilepsy is one of the most common neurological disorders . Many individuals continue to have seizures despite medical and surgical treatments, suggesting adjunctive management strategies are required. Promising effects of daily listening to Mozart on reducing seizure frequency in individuals with epilepsy have been demonstrated over the last 20 years, but not in a rigorously… Continue reading Daily listening to Mozart reduces seizures in individuals with epilepsy: A randomized control study
Atrial Cardiopathy in the Absence of Atrial Fibrillation Increases Risk of Ischemic Stroke, Incident Atrial Fibrillation, and Mortality and Improves Stroke Risk Prediction
Atrial fibrillation (AF) is a major, often undetected, cardiac cause of stroke. Markers of atrial cardiopathy, including left atrial enlargement (LAE) or excessive atrial ectopy (EAE) increase the risk of AF and have shown associations with stroke. We sought to determine whether these markers improve stroke risk prediction beyond traditional vascular risk factors (eg CHA2DS2‐VASc… Continue reading Atrial Cardiopathy in the Absence of Atrial Fibrillation Increases Risk of Ischemic Stroke, Incident Atrial Fibrillation, and Mortality and Improves Stroke Risk Prediction
Cigarette Smoking and Incident Stroke in Blacks of the Jackson Heart Study
Blacks are disproportionately affected by stroke compared with whites; however, less is known about the relationship between stroke and cigarette smoking in blacks. Therefore, we evaluated the relationship between cigarette smoking and all incident stroke in the JHS (Jackson Heart Study).. JHS participants without a history of stroke (n=4410) were classified by self‐reported baseline smoking… Continue reading Cigarette Smoking and Incident Stroke in Blacks of the Jackson Heart Study
Association Between Thrombolytic Door-to-Needle Time and 1-Year Mortality and Readmission in Patients With Acute Ischemic #Stroke
Earlier administration of intravenous tissue plasminogen activator (tPA) in acute ischemic stroke is associated with reduced mortality by the time of hospital discharge and better functional outcomes at 3 months. However, it remains unclear whether shorter door-to-needle times translate into better long-term outcomes.. ..Among the 61 426 patients treated with tPA within 4.5 hours, the median… Continue reading Association Between Thrombolytic Door-to-Needle Time and 1-Year Mortality and Readmission in Patients With Acute Ischemic #Stroke
Complement-Dependent Synaptic Uptake and Cognitive Decline after #Stroke and Reperfusion Therapy
..This study addresses two major challenges facing the treatment of stroke in the era of reperfusion therapy: hemorrhagic transformation and the disconnect between successful revascularization and functional outcomes. We studied how complement-dependent neuroinflammation drives the pathophysiology behind these challenges using a translationally relevant strategy. Complement inhibition was achieved using B4Crry, an injury site-targeted inhibitor of… Continue reading Complement-Dependent Synaptic Uptake and Cognitive Decline after #Stroke and Reperfusion Therapy
Afternoon distraction: a high-saturated-fat meal and endotoxemia impact postmeal attention in a randomized crossover trial
Saturated-fat intake and endotoxemia can impair cognition. However, their acute impact on cognitive performance is unknown.. In this double-blind, randomized crossover trial, 51 women (n = 32 breast cancer survivors, n = 19 noncancer controls; mean ± SD age: 53 ± 8 y) completed the Continuous Performance Test (CPT) and had their blood drawn to… Continue reading Afternoon distraction: a high-saturated-fat meal and endotoxemia impact postmeal attention in a randomized crossover trial
Physical presence of spouse enhances brain-to-brain synchrony in co-parenting couples
Co-parenting spouses who live together remain in close physical proximity to each other and regularly engage in reciprocal social interactions in joint endeavors to coordinate their caregiving. Although bi-parental rearing is a common occurrence in humans, the influence of the physical presence of a co-parenting spouse on parental brain responses remains largely unknown. Synchrony is… Continue reading Physical presence of spouse enhances brain-to-brain synchrony in co-parenting couples
