Background: The Arm Function in Multiple Sclerosis Questionnaire (AMSQ) has been developed to assess upper extremity function of patients with multiple sclerosis (MS). A minimal clinically important difference (MCID) value has not been determined yet.
Objective: The objective of this study is to determine an MCID for AMSQ.
Methods: We used the sensitivity- and specificity-based approach with dichotomized global perceived effect as an anchor.
Results: The receiver operating characteristic (ROC) curve yielded an optimal threshold value of 14.5 (sensitivity 0.68 and specificity 0.79). The area under the ROC curve value was 0.77.
Conclusion: We identified an MCID of 15 points for the AMSQ (range 31-186).

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.

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.

Autologous haematopoietic stem cell transplantation (AHSCT) is a treatment option for relapsing forms of multiple sclerosis (MS) that are refractory to disease-modifying therapy (DMT). AHSCT after failure of high-efficacy DMT in aggressive forms of relapsing-remitting MS is a generally accepted indication, yet the optimal placement of this approach in the treatment sequence is not universally agreed upon. Uncertainties also remain with respect to other indications, such as in rapidly evolving, severe, treatment-naive MS, progressive MS, and neuromyelitis optica spectrum disorder (NMOSD).

Background Hemimegalencephaly (HME) is a rare congenital disorder that is initiated during embryonic development with abnormal growth of one hemisphere. Tuberous sclerosis complex (TSC), a genetic disorder, is rarely associated with HME. Methods We present a case of a newborn with HME with a confirmed mutation in the TSC-1 gene and describe the clinical course, findings on (amplitude integrated) electroencephalography (aEEG), cranial ultrasound (CUS), MRI, and the postmortem evaluation.
