Background: Late-onset multiple sclerosis (LOMS or L; MS) and early-onset MS (EOMS or E) are less common, and their prognosis can be different. To characterize the demographic and clinical features, and clinical outcomes of LOMS and EOMS patients, comparing them to adult-onset MS (AOMS or A) patients. Methods: The study was conducted as a secondary analysis of a prospective study. The participants were divided into three groups according to age of MS onset: early onset (<18 years of age), adult-onset (20-40 years of age), and late-onset (>55 years of age). Demographic variables, oligoclonal bands, IgG index, and Expanded Disability Status Scale (EDSS) score in admission, first year, second year and current EDSS were evaluated. The Timed 25- Foot Walk Test (T25FW), Timed Up and Go (TUG), Multiple Sclerosis Walking Scale-12, Single Leg Standing Test, Activity-Specific Balance Confidence Scale, Nine-Hole Peg Test, Epworth Sleepiness Scale and Restless Legs Syndrome Severity Scale were performed. Appropriate statistical analysis was made. Results: A total of 658 pwMS was included in the study and divided into three groups: EOMS (n n = 117), AOMS (n n = 499), and LOMS (n n = 42). Statistically significant differences were determined between groups in terms of age [L (mean:59.86+5.45 +5.45 years-y-)> A (36.87+9.12 +9.12 y)> E (26.56 +8.85 y), p < 0.001], education level, current EDSS score (L L > E, p < 0.001), EDSS score in first admission, EDSS score in the first year, EDSS score in the second year (L L > A > E, p < 0.001), reached an EDSS score 6 (E E > L p = 0.001, E > A p = 0.015), disease duration (E E > A, E > L , mean E = 11.66+9.7 +9.7 y, A = 7.99+7.4 +7.4 y, L = 6.31+4.67 +4.67 y) time switching second-line treatment to the third line (E E > L p < 0.001, A > L p = 0.002, mean E = 171.73+83.29 +83.29 months-m-, A = 136.13+65.75 +65.75 m, L = 65.85 +45.96 m), number of relapses (A A > E > L , median E = 4.0, A = 3.0, L = 2.0), distribution of MS type and oligoclonal band types. Significant differences were found in T25FW and TUG. Post-hoc analysis showed that participants in the LOMS group have longer T25FW (mean L = 7.8 + 6.11, A = 6.25+5.09, +5.09, E = 5.72+3.13, +3.13, p = 0.011) and TUG (mean L = 11.01+5.53, +5.53, A = 9.57+8.04, +8.04, E = 8.38+5.51, +5.51, p = 0.007) times than the AOMS and EOMS groups. Conclusion: Our result revealed that individuals with LOMS face elevated disability levels and a heightened propensity to transition from first-line treatments to more advanced therapeutic interventions. LOMS have worse lower extremity functional status than AOMS and EOMS patient. Clinical evaluations and treatment choices require more attention in LOMS. However, according to the low number of LOMS in our cohort, these results were considered cautious, and more wide and multi-center studies must be designed.

The Relationship Between Work Difficulties and Physical Disability, Cognitive and Social Cognitive Impairment and Subcortical Gray Matter Atrophy in Persons With Multiple Sclerosis
(Springer Heidelberg, 2024) Aslan, Taha; Ozdogar, Asiye Tuba; Sagici, Ozge; Ozakbas, Serkan
Background Multiple sclerosis (MS) is commonly associated with work difficulties. This study aimed to examine the relationship between work difficulties and physical disability, cognitive and social cognitive impairment, and subcortical gray matter (scGM) atrophy in pwMS. Methods Thirty-three employees with MS underwent assessments with Multiple Sclerosis Work Difficulties Questionnaire-23 MSWDQ-23. Physical disability was measured using EDSS, Timed 25-Foot Walk (T25FW), 2-Minute Walking Test (2-MWT), the Nine-Hole Peg test (N-HPT), and 12-item Multiple Sclerosis Walking Scale (MSWS-12). Cognitive functions were evaluated with Brief International Cognitive Assessment in MS (BICAMS), social cognition with Facial Emotion Identification (FEI), Reading the Mind in the Eyes Test (RMET), and Empathy Quotient (EQ). Anxiety and depression were assessed using Hospital Anxiety and Depression Scale (HADS). The association between variables was analysed using Spearman's correlation coefficient. GM volumes were calculated from 3T MRI data using Freesurfer, their potential relationship with work difficulties were evaluated through a linear regression model. Results MSWDQ-23 was strongly correlated with T25FW and MSWS-12 (p<0.01), moderately correlated with EDSS, 2MWT, HAD, BICAMS, and EQ (p<0.05). According to the linear regression model the decrease in volumes of total GM and scGM, bilateral Thalamus, bilateral Hippocampus, left Putamen, and right Caudate related with the severity of work difficulties (R-2=0.815, p=0.25). Conclusion This study provides valuable insights into the multifaceted nature of work difficulties experienced by pwMS. It suggests that not only physical disability but also other factors, such as mood, cognition, empathy, and cortical and subcortical gray matter atrophy may contribute to work difficulties among pwMS.
