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 (R²=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.
