Objective: To explore the relationship of the Multiple Sclerosis Neuropsychology Questionnaire (MSNQ; [Benedict, R. H. B., Cox, D., Thompson, L. L., Foley, F., Weinstock-Guttman, B., & Munschauer, F. (2004). Reliable screening for neuropsychological impairment in multiple sclerosis. Multiple Sclerosis, 10, 675-678; Benedict, R. H. B., Munschauer, F., Linn, R., Miller, C., Murphy, E., Foley, F., et al. (2003). Screening for multiple sclerosis cognitive impairment using a self-administered 15-item questionnaire. Multiple Sclerosis, 9, 95-101]), a self-report screening measure of neuropsychological functioning in multiple sclerosis (MS), with everyday life functioning, neuropsychological functioning, and mood in MS. Additionally, to investigate the validity, sensitivity, and specificity of the MSNQ to predict cognitive impairment in persons with MS.
Study Design: Cross-sectional, correlational analyses; analyses of sensitivity and specificity.
Setting: Neuropsychology lab-based study with adults from the community including persons with MS (n=48) and healthy adults (n=40).
Main Outcome Measures: Subjective and objective measures of everyday life functioning, neuropsychological functioning, and mood; ROC curve of MSNQ-Self report and MSNQ-Informant report, sensitivity and specificity of MSNQ-S and MSNQ-I.
Results: Correlational analyses indicate the MSNQ-S is significantly correlated with mood and self-reports of functioning, but not with objectively measures daily functioning and to only few neuropsychological tests. The MSNQ-I was not significantly correlated to mood, self-report of daily functioning or objectively measured daily functioning, but was significantly correlated with several measures of neuropsychological functioning.
Conclusion: The MSNQ-S was not supported as a sensitive screen for neuropsychological impairment in MS. However, the MSNQ-I was supported as a valid and sensitive screen of cognitive impairment in persons with MS, although further research is needed to determine an optimal cutoff score for this measure.

High-Field-Blinded Assessment of Portable Ultra-Low-Field Brain MRI for Multiple Sclerosis.

Background And Purpose: MRI is crucial for multiple sclerosis (MS), but the relative value of portable ultra-low field MRI (pULF-MRI), a technology that holds promise for extending access to MRI, is unknown. We assessed white matter lesion (WML) detection on pULF-MRI compared to high-field MRI (HF-MRI), focusing on blinded assessments, assessor self-training, and multiplanar acquisitions.
Methods: Fifty-five adults with MS underwent pULF-MRI following their HF-MRI.
Should you hold onto the treadmill handrails or not? Cortical evidence at different walking speeds.

Background: Treadmill-based gait training is part of rehabilitation programs focused on walking abilities. The use of handrails embedded in treadmill systems is debated, and current literature only explores the issue from a behavioral perspective.
Methods: We examined the cortical correlates of treadmill walking in healthy participants using functional near-infrared spectroscopy.

To determine correlation between the Extended Disability Status Scale(EDSS) grade and the progression of neuromyelitis optica(NMO) patients' levels of the chemokine CXC ligand 13 (CXCL13) in their serum and cerebrospinal fluid. This research included forty-one patients diagnosed with neuromyelitis optica(NMO) and forty-three patients diagnosed with multiple sclerosis(MS). The control group consisted of forty-three non-inflammatory neurological disease(NND) patients.

Inflammatory diseases are often chronic and recurrent, and current treatments do not typically remove underlying disease drivers. T cells participate in a wide range of inflammatory diseases such as psoriasis, Crohn's disease, oesophagitis and multiple sclerosis, and clonally expanded antigen-specific T cells may contribute to disease chronicity and recurrence, in part by forming persistent pathogenic memory. Chronic rhinosinusitis and asthma are inflammatory airway diseases that often present as comorbidities.
