83 vs 0.77). It is increased in sensitivity but decreased in specificity. Conclusion The McDonald criteria are useful in predicting second events in multiple sclerosis. The 2017 McDonald criteria have better performance than the 2010 McDonald criteria with increased sensitivity but decreased specificity.Background As cognitive, emotional, and health-related behavioral issues are prevalent among persons with multiple sclerosis (MS), mental health services are a valuable component of comprehensive care. However, it is unknown how many participate in neuropsychological and psychotherapeutic services, and whether the presence of certain co-occurring conditions increase service use. BMS-1166 This study aimed to examine the frequency and associated factors (e.g., age, gender, education, race/ethnicity, and co-occurring conditions) of neuropsychological and psychotherapeutic service utilization in the Veterans Health Administration (VHA) among Veterans with MS. Methods Data were extracted from VHA Corporate Data Warehouse as part of the Women Veterans Cohort Study (WVCS), a longitudinal project with Veterans who served during the Iraq and Afghanistan conflicts. Participants (n = 1,686) were Veterans from the overall WVCS dataset who had three or more VHA MS-related encounters (inpatient, outpatient, and/or disease modifying% CI 2.29, 6.16). Conclusions These findings suggest that these services are being utilized by clinicians and Veterans to address the clinical complexity related to having MS and one or more of these other conditions.Background Uveitis describes intraocular inflammation of the uveal tract. It may occur in the absence of a predisposing underlying condition, or may be secondary to a systemic autoimmune disease or ocular infection. An association with Multiple Sclerosis (MS) has also been observed. Objectives To investigate the association between MS and uveitis in UK Biobank. Methods 1696 individuals with MS were identified within UK Biobank using ICD-10 code G35 and 626 individuals with uveitis were identified using ICD-10 codes H20, H30, and H22.1. Participants who had a comorbid autoimmune condition that could also be associated with uveitis were excluded from analysis, as were those in whom MS was diagnosed prior to uveitis. 1568 individuals with MS and 470 individuals with uveitis were included in the final analysis. We used multivariable logistic regression to model uveitis diagnosis on MS status and control for confounding factors (age, sex, and socio-economic status). We also examined phenotypic and genetic characteristics of individuals with both conditions. Results Uveitis prevalence in people with MS was 0.51%, compared to 0.10% in controls. The adjusted odds ratio (OR) of MS given a diagnosis of uveitis was OR 5.25, 95% CI 2.6 - 10.6, p=0.00024. 87.5% of people with both diagnoses were female and 87.5% identified as White. 25.0% were DRB1*15 heterozygotes, while 75.0% carried no copies of the DRB1*15 risk allele. Conclusions These findings support the suggested association of these two conditions and demonstrate a comparable predominance of white females with both conditions.Background Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune, demyelinating disorder, accompanied by abnormal spontaneous activity of the brain and impairment of the retina and optic nerve. Functional connectivity density (FCD) map, a graph theory method, was applied to explore the functional connectivity alterations of brian in NMOSD patients and investigate the alterations of FCD to the structural and microvascular changes around the optic nerve head (ONH). Methods Nineteen NMOSD patients and 22 healthy controls (HCs) were included in our study. All participants underwent resting-state functional magnetic resonance imaging (fMRI) scans of the brain, and ophthalmological examinations included optical coherence tomographic angiography (OCT-A) imaging, visual acuity (VA), and intraocular pressure (IOP). The long- and short-range FCD was calculated by the fMRI graph theory method and two-sample t-tests were performed to compare the discrepancy of FCD between NMOSD and HCs. OCT-A imaging was used tly correlated with the long-range FCD values in the right FFG, left ORBsup, and left ACG as well as short-range FCD values in the right FFG, besides, both were positively correlated with the long-range FCD values in the right SPG and short-range FCD values in the left ANG and right SPG (p less then 0.05). Conclusion Our study demonstrates that patients with NMOSD have widespread brain dysfunction after optic neuritis attacks which shows as impairment of widespread spatial distribution in long- and short-range FCD. Structural and microvascular changes around the ONH are associated with neural changes in the brain.Background Large-scale functional abnormalities and decreased synchronization between functionally connected regions within brain networks were reported in progressive multiple sclerosis (P-MS) patients. Low concentration of gamma-aminobutyric acid (GABA) was observed in the sensorimotor cortex (SMC) of these patients and was associated with reduced motor functions of limbs. Yet, the role of GABA in modulating functional connectivity (FC) has not been investigated in MS patients. Objectives To determine the relationship between GABA concentration in the SMC and short-term FC changes within the sensorimotor network (SMN) in P-MS patients. Methods Combining magnetic resonance spectroscopy (MRS) and resting-state functional MRI (rs-fMRI), we investigated the relationship between baseline GABA concentration in the left SMC and FC within SMN in P-MS patients compared to healthy controls (HCs). Additionally, we assessed the relationship between baseline GABA concentration and FC changes over a 1-year follow-up period in the patients' group only. Results At baseline, lower GABA levels, and decreased FC levels in regions within the SMN were observed in MS patients compared to healthy controls (HCs). Overtime, an increase in FC was observed in regions within the SMN in the MS group. This increase correlated inversely with motor performance scores. Conclusions We postulate that in P-MS patients, lower levels of GABA in the SMC contribute to decreased inhibition, and as a result, to a reactive increase of FC in inter-connected sensorimotor brain regions, thus minimizing clinical worsening.
