Cover Story: The following study explores the complex relationships between specific Theory-of-Mind (ToM) dimensions, sleep duration, and cognitive planning in healthy aging and individuals with Mild Cognitive Impairment (MCI). Our findings revealed that non-amnestic MCI (naMCI) is linked to significant ToM impairments, particularly in understanding non-literal speech comprehension (sarcasm, humor, irony, and faux pas understanding) and third-order ToM story understanding; in comparison, amnestic MCI (aMCI) shows milder deficits. Reduced sleep duration impacts ToM performance indirectly through cognitive planning, highlighting the role of specific executive functions in social cognition. These insights underline the need for targeted interventions to improve social understanding and quality of life in older adults. View this paper
