Summary: This study evaluated the clinical significance of deep learning-derived brain age prediction in NMOSD and RRMS. The results showed that both NMOSD and RRMS patients had a significantly higher brain age gap compared to healthy controls. The brain age gap was associated with baseline disability score, advanced brain volume loss, and disease duration. Additionally, the brain age gap predicted the worsening of disability status in both NMOSD and RRMS patients.

Summary: The study explored the association between PRRC2A variants and susceptibility to NMOSD and MS in the Han Chinese population. Certain PRRC2A variants were found to alter susceptibility to AQP4(+)NMOSD and MS, with specific genotypes increasing the risk. Additionally, haplotypes and gene expression levels associated with these variants were identified, suggesting potential implications for personalized therapeutic approaches in these disease entities.

Summary: Spinal cord involvement is a key feature of multiple sclerosis, neuromyelitis optica with AQP4 antibodies, and MOG-antibody disease. Quantitative spinal cord MRI was used in a cross-sectional study to differentiate these conditions, showing significant damage in AQP4-antibody disease and multiple sclerosis, while MOG-antibody disease had a predominant central grey matter component. The study also found that relapsing MOG-antibody disease is a more severe phenotype and applied various analyses to discriminate between different diseases.

Summary: This pilot study evaluated dynamic thiol-disulfide homeostasis as an oxidative stress parameter in neuroimmunological diseases, finding a significant relationship between clinical features and thiol homeostasis. Serum biomarkers of thiol homeostasis differed from CSF levels, indicating a potential role in monitoring disease activity.

Summary: Neuromyelitis optica spectrum disorder (NMOSD) and multiple sclerosis (MS) are inflammatory diseases of the CNS with overlapping clinical and MRI features, but distinguishing them can be achieved with the use of MRI features and machine learning models.

Summary: This study investigated the impact of multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) on the cerebellar connectome. The findings showed both shared and specific alterations in the connectome between MS and NMOSD, with MS patients exhibiting increased morphological connectivity within the cerebellar secondary motor module and NMOSD patients showing increased connectivity between the cerebellar primary motor module and cerebral motor- and sensory-related areas. Additionally, both diseases had decreased functional connectivity between cerebellar motor modules and cerebral association cortices.

Summary: This study compared IQ scores in NMOSD, MS, and control groups, and found that IQ scores were lower in both NMOSD and MS patients compared to the control group. Higher EDSS scores in the NMOSD group were associated with lower scores in FSIQ, VIQ, and PIQ. Advanced education in both NMOSD and MS groups was associated with higher scores in FSIQ and VIQ.

Summary: Multiple sclerosis (MS) and Devic's disease (NMO) are autoimmune, inflammatory diseases of the central nervous system with unclear etiology. Th17 cells and related cytokines may be useful as discriminatory markers for these diseases, but broader immune response mechanisms must also be considered.

Summary: The characteristics of optic nerve impairment in neuromyelitis optica spectrum disorders (NMOSD) and multiple sclerosis (MS) patients were assessed using fractional anisotropy (FA). The study found that FA values were significantly decreased in the optic nerves of NMOSD patients, especially in the posterior segment. FA values in the anterior and middle segments of the optic nerve were also decreased in MS patients. Significant differences in FA values were observed in the posterior segment between NMOSD and MS patients. The combination of FA and signal intensity ratio (SIR) showed good diagnostic performance in distinguishing between NMOSD and MS.

Summary: Neuromyelitis optica spectrum disorder (NMOSD) and multiple sclerosis (MS) are autoimmune inflammatory and demyelinating diseases of the central nervous system. Differentiating between NMOSD and MS is crucial for the timely and appropriate treatment. In this study, infrared spectroscopy combined with machine learning successfully distinguished NMOSD and MS patients with 100% sensitivity and specificity. The method shows promise as a cost-effective and rapid diagnostic tool to help save valuable treatment time for patients.

Summary: This study aimed to determine the extent of sudomotor dysfunction in patients with neuromyelitis optica spectrum disorder (pwNMOSD) and compare it with patients with relapsing-remitting multiple sclerosis (pwRRMS). The results showed that sudomotor dysfunction is common in pwNMOSD, and symptoms are more frequent compared to pwRRMS. Age and diagnosis of neuromyelitis optica spectrum disorder were significant predictors for symptomatic sudomotor dysfunction.

Summary: This study highlights the importance of attack prevention to avoid severe neuroaxonal damage and vision loss caused by ON in NMOSD. Therapies to ameliorate attack-related damage, especially during the first attack, are a clinical need. Mild neuroaxonal changes in ON-unaffected eyes may be solely due to contralateral ON attacks and do not indicate clinically relevant progression, but require further investigation.
