UNASSIGNED: Although Theory of Mind (ToM) is thought to be impaired in @entity195 ( @entity195 ), it remains unclear whether this impairment is linked to the level of task complexity, the heterogeneity of the studied @entity1 , or the implication of executive dysfunctions. To elucidate this point, 42 @entity195 @entity1 , divided into two subgroups [moderate @entity195 (mAD) @entity1 (n  =  19) and early @entity195 (eAD) @entity1 (n  =  23)], and 23 matched healthy older subjects (HO) were enrolled. All @entity1 were given (1) a false-belief task (cognitive ToM), (2) a revised version of the "Reading the Mind in the Eyes" test (affective ToM), and (3) a composite task designed to assess ToM abilities with minimal cognitive demands. @entity1 were also given executive tasks assessing inhibition, shifting, and updating processes. We observed a significant @entity73 in eAD @entity1 compared with mAD @entity1 . There was no impairment of affective ToM. Stepwise regression revealed that measures of global efficiency and executive functions (EFs) were the best predictors of progressive decay of ToM scores. These results indicate that cognitive aspects of ToM are more sensitive to @entity195 progression than affective tasks. They also show that ToM abilities are more affected by @entity303 severity than by task complexity. One explanation of our results is the presence of compensatory mechanisms (social reserve) in @entity195 .
