Comparison of Social Cognition Impairments in Neurodegenerative Diseases: A Literature Review

Poster : Social cognition impairments, including difficulties in understanding emotions and social interactions, are common in neurodegenerative diseases. This literature review compares social cognitive deficits in Alzheimer’s disease (AD), Huntington’s disease (HD), and Amyotrophic Lateral Sclerosis (ALS). Although each condition presents a specific profile, common alterations are reported, particularly in emotion recognition and theory of mind. HD is characterized by early and severe impairments in emotional recognition. In AD, the main deficits concern theory of mind and emotion recognition. ALS is associated with more subtle difficulties, especially in interpreting others' emotions and intentions. These impairments, which vary across diseases, are likely to affect patients’ social interactions. A better understanding of their specific features would help refine assessment tools and adapt care strategies. This analysis highlights the importance of social cognition in patient follow-up and the optimization of therapeutic interventions.
