Social cognition in Multiple Sclerosis

Social cognition (SC) encompassed the cognitive processes underlying personal relationships. It is the capacity to recognize and interpret interpersonal cues that guide social behaviour.1 Recent studies showed that, persons with Multiple Sclerosis (MS), could be impaired for SC.² Studies mainly focused on emotion recognition, facial emotion recognition or theory of mind (ToM) in its 2 components, cognitive and affective ToM.² Facial emotion recognition has been investigated in MS in several studies,3-11 and the most frequently used paradigm was Ekman faces test.12 Several studies² but not all3,4,11 showed differences between MS patients and healthy subjects (HS). A recent study showed that the proportion of impaired patients for facial recognition varies from 7 to 27% according to phenotype, the greater proportion being observed in primary progressive MS (PPMS).11 Another recent study reported that patients with PPMS performed worse than both HS and patients with relapsing-remitting MS (RRMS) on the recognition of fearful facial expressions, while patients with secondary progressive MS (SPMS) performed worse on the recognition of facial expressions of sadness.13 Correlations between facial recognition and cognitive scores at classical neuropsychological tests used in MS were not consistently found.

ToM have been found impaired in many studies using different tasks, including attribution of intentions or thoughts, such as False belief tasks, Eyes Test, Strange Stories Tasks or video tasls such as the Movie for the Assessment of Social Cognition (MASC) and the Conversations and Insinuations Video (C&I) Task.2,4,5,8,13-17,  Considering phenotypes, the proportion of ToM impaired MS patients varied from 20 to 37%, the later in RRMS. Another study found more ToM impairment in progressive MS.13

The correlation of ToM impairment with CI is still a matter of debate but some studies found some correlations between ToM tasks and neurocognitive performances, especially with effective functions, processing speed and working memory.13,14,17 In a recent study, a significant correlation between executive functioning, episodic and working memory and ToM scores was observed using a relatively large cognitive battery.11 Scores in these domains accounted for more than 50% of ToM impairment and the correlations were observed for the three ToM tests used in this study, the Reading the Mind in the Eyes test, the Attribution of Intention test and the Faux Pas test. These results suggested that efficient executive functions contribute to normal SC functioning.

Two important questions remain to be answered. The first one is the importance of the consequences in the daily lives of MS patients of these impairments. Especially the consequences on inter-personal relationships in familial and social activities are unknown. The second is the question of the neuroanatomic basis of SC impairment in MS. Only a few functional and structural MRI studies (fMRI) studies have investigated SC in MS and their results are preliminary17-21 and other studies are needed for understanding the relationship between SC impairment and the disease process in MS.
