Abstract

Social-cognitive difficulties can negatively impact interpersonal communication, shared social experience, andmeaningful relationships. This pilot investigation examined the relationship between social-cognitive functioningand inflammatory markers in people with multiple sclerosis (MS) and demographically-matched healthy individuals. Additionally, we compared the immune marker profile in serum and urine-matched samples. Socialcognitive functioning was objectively assessed using The Awareness of Social Inference Test – Short (TASIT-S) andsubjectively assessed using self-reports of abilities in emotion recognition, emotional empathy, and cognitivetheory of mind. In people with MS and healthy individuals, there were moderate-to-large negative relationshipsbetween pro-inflammatory biomarkers (serum IL-1β, IL-17, TNF-α, IP-10, MIP-1α, and urine IP-10, MIP-1β) of theinnate immune system and social-cognitive functioning. In MS, a higher serum concentration of the antiinflammatory marker IL-1ra was associated with better social-cognitive functioning (i.e., self-reportedemotional empathy and TASIT-S sarcasm detection performance). However, there were mixed findings foranti-inflammatory serum markers IL-4 and IL-10. Overall, our findings indicate a relationship between proinflammatory cytokines and social-cognitive abilities. Future studies may provide greater insight intobiologically-derived inflammatory processes, sickness behaviour, and their connection with social cognition.
