Second-order false belief tests for dementia


We tested the hypothesis that the changes in personality and behaviour seen in frontal variant frontotemporal dementia fvFTD may reflect impairment in this cognitive domain. By contrast, the Alzheimer's disease group failed only one ToM task second-order false beliefwhich places heavy demands on working memory. A key aspect of social cognition is the ability to infer other people's mental states, thoughts and feelings; referred to as 'theory of mind' ToM. This study supports the hypothesis that patients with fvFTD, but not those with Alzheimer's disease, are impaired on tests of ToM, and may explain some of the abnormalities in interpersonal behaviour that characterize fvFTD. Patients with fvFTD were impaired on all tests of ToM first-order false belief; second-order false belief; faux pas detection; and Reading the Mind in the Eyesbut had no difficulty with control questions designed to test general comprehension and memory. Performance on the faux pas test revealed a double dissociation, with the fvFTD group showing deficits on ToM-based questions and the Alzheimer's disease group failing memory-based questions only. Rank order of the fvFTD patients according to the magnitude of impairment on tests of ToM and their degree of frontal atrophy showed a striking concordance between ToM performances and ventromedial frontal damage.
