Cognitive impairment in multiple sclerosis is difficult to study because of the heterogeneity and variability of this disease. The gold standard for measurement of cognitive function in multiple sclerosis is a full battery of neurocognitive tests, which is time consuming and expensive. Some cognitive tests like the PASAT, a measure of working verbal memory and processing speed, have been proposed for screening and follow-up of cognitive function in clinical trials. We studied whether we could measure cognitive function in multiple sclerosis over the Internet. For this we used the Cognitive Stability Index (CSI)™, developed for persons with known or suspected primary central nervous system illness. The CSI was compared with formal neurocognitive testing (NPsych) and the PASAT in a cross-sectional study of 40 consecutive multiple sclerosis patients with subjective cognitive complaints. NPsych revealed that only 18 of the 40 patients (46%) were cognitively impaired. Although both the CSI and the PASAT were equalivalent in their specificity (86%), the CSI was significantly more sensitive than the PASAT (83% versus 28%). We conclude that the CSI, because of its availability over the Internet, has great potential as a tool for screening and follow up of cognitive function in multiple sclerosis.

Background: In multiple sclerosis (MS), various aspects of cognitive function can be detrimentally affected, thus patients’ employment and social functioning is commonly impacted. Objective: To analyse income among MS patients in relation to cognitive function, assessed with the Symbol Digit Modalities Test (SDMT). Methods: A cross-sectional study including 2080 MS patients was conducted linking national register-based data. Descriptive statistics and a two-part model were used to estimate differences in earnings and social benefits. Results: MS patients in the highest SDMT score quartile earned more than twice annually compared to patients in the lowest quartile, whereas patients in the lowest quartile received three times more income through social benefits. The difference in earnings and benefits across the SDMT performance quartiles remained statistically significant after adjusting for various clinical and socio-demographic variables, including physical disability. The corrected prevalence ratios for MS patients in the highest quartile for having income from earnings and benefits were 1.40 (95% confidence interval (CI): 1.29–1.49) and 0.81 (95% CI: 0.71–0.90), respectively, when compared to the patients in the lowest quartile. Conclusion: Cognitive function affects the financial situation of MS patients negatively and independently of physical disability. This warrants cognitive testing as a routine measure in health care services for MS patients.

In previous studies the estimation of the incidence of intellectual changes in multiple sclerosis has varied from as low as 2 per cent. (Cottrell and Wilson, 1926) to as high as 72 per cent. (Ombredane, 1929). In order to establish the incidence accurately, the most satisfactory method would clearly be a long-term follow-up (covering lifetime) of a sample of multiple sclerosis patients. Any cross-sectional study would include patients in varying degrees of advancement of the disease, and patients found to be free of intellectual deficits at the time of investigation would not necessarily remain so. Also, the indirect psychometric assessment of intellectual loss is notoriously difficult, and the direct method of follow-up would give much more accurate results. The only direct study up to date has been that of Canter (1951), who found a highly significant (i.e. 13·48 points) loss on re-testing multiple sclerosis patients on the Army General Classification Test after a four-year period. Even after such a short period as six months he found slight losses on most Wechsler-Bellevue subtests, in contrast to an average gain of six full IQ points of the control group.

Objective: The cross-sectional study evaluated the psychometric properties of the Functional Assessment of Multiple Sclerosis (FAMS) Spanish version and its use in measuring quality of life (QOL) of multiple sclerosis (MS) patients in Spain. Methods: The FAMS is a factorially derived self-report scale designed to assess six primary aspects of QOL of patients with MS: Mobility, Symptoms, Emotional Well-Being, General Contentment, Thinking and Fatigue, and Family/Social Well-Being. Its Spanish translated version was used to assess QOL of 625 MS patients recruited in an outpatient clinic setting from 58 hospitals in Spain. Internal consistency of the Spanish FAMS was evaluated. Multiple regression analyses were performed to identify significant predictors from demographic, clinical and treatment characteristics, and Kurtzke Expanded Disability Status Scale (EDSS) scores in predicting FAMS scale scores. Results: Most of the patients are females (66%), and 74% were of the relapsing-remitting (RR) clinical subtype. Cronbach’s alpha coefficients were high (range=0.78-0.96), indicating subscale homogeneity comparable to that of the original English version. Linear multivariate regression analyses revealed that the EDSS is a dominant variable in predicting all the FAMS subscales, especially mobility (R2=0.51) and the total scores. Conclusions: The Spanish FAMS is a psychometrically valid instrument that allows clinicians and clinical researchers the ability to measure the QOL concerns of MS patients in Spain.

Background: The soluble isoform of the interferon-β (IFN-β) receptor (sIFNAR2) could modulate the activity of both endogenous and systemically administered IFN-β. Previously, we described lower serum sIFNAR2 levels in untreated multiple sclerosis (MS) than in healthy controls (HCs). Objective: To assess sIFNAR2 levels in a new cohort of MS patients and HCs, as well as in patients with clinically isolated syndrome (CIS) and with other inflammatory neurological disorders (OIND) and to assess its ability as a diagnostic biomarker. Methods: The cross-sectional study included 148 MS (84 treatment naive and 64 treated), 87 CIS, 42 OIND, and 96 HCs. Longitudinal study included 94 MS pretreatment and after 1 year of therapy with IFN-β, glatiramer acetate (GA), or natalizumab. sIFNAR2 serum levels were measured by a quantitative ELISA developed and validated in our laboratory. Results: Naive MS and CIS patients showed significantly lower sIFNAR2 levels than HCs and OIND patients. The sensitivity and specificity to discriminate between MS and OIND, for a sIFNAR2 cutoff value of 122.02 ng/mL, were 70.1%, and 79.4%, respectively. sIFNAR2 increased significantly in IFN-β-treated patients during the first year of therapy in contrast to GA- and natalizumab-treated patients who showed non-significant changes. Conclusion: The results suggest that sIFNAR2 could be a potential diagnostic biomarker for MS.

Abstract Background Approximately half of all patients with multiple sclerosis (MS) experience cognitive impairment, most commonly with regard to new learning and memory. Cognitive dysfunction is a leading cause of disability in MS and it can have profound social and economic consequences for patients and their families. Objective This study was conducted to discover the early cognitive domains affected in multiple sclerosis patients concomitant with the postulated brain atrophy in an Egyptian sample of multiple sclerosis patients. Patients and Methods A cross-sectional observational case-control study conducted on seventy (60) patients who came for follow-up in Ain Shams University hospitals. 40 patients were taken as cases that followed up in MS unit in Ain-Shams university hospitals. 20 participants were taken as controls taken from the general medicine clinics age and sex matched to our patient group. An informed written consent was taken from parents of each person included in the study. Results There was a statistically significant difference between the two groups in brain volumetric changes and in the parameters of cognitive assessment Conclusion Early detection and examination of cognitive functions is important for patient evaluation, follow up and treatment regimen used.
