The rs10191329 Risk Allele Is Associated With Pronounced Retinal Layer Atrophy in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To investigate whether the rs10191329 risk allele in the DYSF–ZNF638 locus, which is implicated in central nervous system resilience rather than immune‐mediated pathology, is associated with retinal layer thinning, a biomarker of neuroaxonal damage in relapsing multiple sclerosis (RMS). Methods From a prospective observational study,

Analysis of Soluble Interleukin‐2 Receptor as a Prognostic Biomarker in NMOSD and MOGAD

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Soluble interleukin‐2 receptor (sIL‐2R) is a biomarker for T cell activity. T cells are involved in neuromyelitis optica spectrum disorders (NMOSD) and myelin oligodendrocyte glycoprotein antibody‐associated disease (MOGAD) pathogenesis. However, sIL‐2R has so far not been evaluated in these conditions.

Altered Dynamic Functional Network Connectivity in Post‐Stroke Aphasia

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Previous studies examining post‐stroke aphasia (PSA) patients via resting‐state functional magnetic resonance imaging (rs‐fMRI) have predominantly focused on static functional connectivity. In contrast, the current investigation aims to elucidate the alterations in dynamic functional network connectivity (dFNC) among PSA patients ...

Prevalence of Stroke and Diagnostic Performance of Emergency MRI in Acute Isolated Dizziness

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Stroke is frequently misdiagnosed in patients presenting with acute isolated dizziness; the optimal imaging modality for this population remains debated. This study aimed to determine the prevalence of stroke among patients with isolated dizziness and to assess the diagnostic accuracy of magnetic resonance imaging (MRI) and computed ...
