Neurofilament light chain in the vitreous humor of the #eye

Neurofilament light chain (NfL) is a promising biomarker of neurodegeneration in the cerebrospinal fluid and blood. This study investigated the presence of NfL in the vitreous humor and its associations with amyloid beta, tau, inflammatory cytokines and vascular proteins, apolipoprotein E (APOE) genotypes, Mini-Mental State Examination (MMSE) scores, systemic disease, and ophthalmic diseases.. ..NfL was detected in all 77 vitreous samples. NfL was not found … Continue reading Neurofilament light chain in the vitreous humor of the #eye

The Importance of Cursive #Handwriting Over Typewriting for Learning in the Classroom: A High-Density #EEG Study of 12-Year-Old Children and Young Adults

To write by hand, to type, or to draw – which of these strategies is the most efficient for optimal learning in the classroom? As digital devices are increasingly replacing traditional writing by hand, it is crucial to examine the long-term implications of this practice. High-density electroencephalogram (HD EEG) was used in 12 young adults and 12, 12-year-old children to study brain electrical activity as … Continue reading The Importance of Cursive #Handwriting Over Typewriting for Learning in the Classroom: A High-Density #EEG Study of 12-Year-Old Children and Young Adults

Evaluation of #green light exposure on #headache frequency and quality of life in #migraine patients: A preliminary one-way cross-over clinical trial

..We recruited (29 total) patients, of whom seven had episodic migraine and 22 had chronic migraine. We used a one-way cross-over design consisting of exposure for 1–2 hours daily to white light emitting diodes for 10 weeks, followed by a 2-week washout period followed by exposure for 1–2 hours daily to green light emitting diodes for 10 weeks. Patients were allowed to continue current therapies … Continue reading Evaluation of #green light exposure on #headache frequency and quality of life in #migraine patients: A preliminary one-way cross-over clinical trial

Relationship Among Sensory Over-Responsivity, Problem Behaviors, and #Anxiety in Emerging Adults with #Autism Spectrum Disorder

Despite the highly prevailing rate of sensory over-responsivity, problem behaviors, and anxiety among emerging adults with autism spectrum disorder (ASD), little is known about the nature of their experiences. While previous studies have indicated potential relationships among these conditions, their connections still need to be clarified. This study aimed to examine the relationships between sensory over-responsivity, problem behaviors, and anxiety.. .. The percentage of emerging … Continue reading Relationship Among Sensory Over-Responsivity, Problem Behaviors, and #Anxiety in Emerging Adults with #Autism Spectrum Disorder

#Language comprehension in the social #brain: Electrophysiological brain signals of social presence effects during syntactic and semantic sentence processing

Although, evolutionarily, language emerged predominantly for social purposes, much has yet to be uncovered regarding how language processing is affected by social context. Social presence research studies the ways in which the presence of a conspecific affects processing, but has yet to be thoroughly applied to language processes. The principal aim of this study was to see how syntactic and semantic language processing might be … Continue reading #Language comprehension in the social #brain: Electrophysiological brain signals of social presence effects during syntactic and semantic sentence processing

#Anticoagulation Timing in Cardioembolic #Stroke and Recurrent Event Risk

Guidelines recommend initiating anticoagulation within 4 to 14 days after cardioembolic stroke. Data supporting this did not account for key factors potentially affecting the decision to initiate anticoagulation, such as infarct size, hemorrhagic transformation, or high‐risk features on echocardiography.. ..We pooled data from stroke registries of 8 comprehensive stroke centers across the United States. We included consecutive patients admitted with ischemic stroke and atrial fibrillation. The … Continue reading #Anticoagulation Timing in Cardioembolic #Stroke and Recurrent Event Risk

Transcriptomic and clonal characterization of #T cells in the human central #nervous system

T cells provide critical immune surveillance to the central nervous system (CNS), and the cerebrospinal fluid (CSF) is thought to be a main route for their entry. Further characterization of the state of T cells in the CSF in healthy individuals is important for understanding how T cells provide protective immune surveillance without damaging the delicate environment of the CNS and providing tissue-specific context for … Continue reading Transcriptomic and clonal characterization of #T cells in the human central #nervous system

Increased risk of acute #stroke among patients with severe #COVID‐19: a multicenter study and meta‐analysis

Recent observations linked coronavirus disease 2019 (COVID‐19) to thromboembolic complications possibly mediated by increased blood coagulability and inflammatory endothelial impairment. We aimed to define the risk of acute stroke in patients with severe and non‐severe COVID‐19.. ..Of 165 patients hospitalized for COVID‐19 (49.1% males, median age 67 [57‐79], 72.1% severe or critical) included in the multicenter study, overall stroke rate was 4.2% (95%CI: 1.9‐8.7). Systematic … Continue reading Increased risk of acute #stroke among patients with severe #COVID‐19: a multicenter study and meta‐analysis

Chromatin accessibility mapping of the striatum identifies tyrosine kinase FYN as a therapeutic target for #heroin use disorder

The current opioid epidemic necessitates a better understanding of human addiction neurobiology to develop efficacious treatment approaches. Here, we perform genome-wide assessment of chromatin accessibility of the human striatum in heroin users and matched controls. Our study reveals distinct neuronal and non-neuronal epigenetic signatures, and identifies a locus in the proximity of the gene encoding tyrosine kinase FYN as the most affected region in neurons. … Continue reading Chromatin accessibility mapping of the striatum identifies tyrosine kinase FYN as a therapeutic target for #heroin use disorder

Associations of #BMI and Serum #Urate with Developing #Dementia: A Prospective Cohort Study

Recent studies suggested that higher BMI and serum urate levels were associated with lower risk of developing dementia. However, these reverse relationships remain controversial, and whether serum urate and BMI confound each other is not well established.. ..During a median of 8.1 years of follow-up, a total of 2138 participants developed dementia. People who were underweight had an increased risk of dementia (hazard ratio [HR] … Continue reading Associations of #BMI and Serum #Urate with Developing #Dementia: A Prospective Cohort Study

Post-traumatic stress disorder as a risk factor for #dementia: systematic review and meta-analysis

Post-traumatic stress disorder (PTSD) has been identified as a potential risk factor for developing dementia. There are currently, however, no meta-analyses quantifying this risk.. ..PTSD was associated with a significant risk for all-cause dementia: pooled hazard ratio HR = 1.61 (95% CI 1.43–1.81, I2= 85.8%, P < 0.001; n = 1 693 678; 8 studies). Pooled HR was 1.61 (95% CI 1.46–1.78; I2= 80.9%, P … Continue reading Post-traumatic stress disorder as a risk factor for #dementia: systematic review and meta-analysis

An atlas on risk factors for type 2 #diabetes: a wide-angled Mendelian randomisation study

..We found evidence of causal associations between 34 exposures (19 risk factors and 15 protective factors) and type 2 diabetes. Insomnia was identified as a novel risk factor (OR 1.17 [95% CI 1.11, 1.23]). The other 18 risk factors were depression, systolic BP, smoking initiation, lifetime smoking, coffee (caffeine) consumption, plasma isoleucine, valine and leucine, liver alanine aminotransferase, childhood and adulthood BMI, body fat percentage, … Continue reading An atlas on risk factors for type 2 #diabetes: a wide-angled Mendelian randomisation study
