Although misidentification syndromes (MISs) have been often described in Alzheimer disease (AD), the prevalence of these phenomena in different neurodegenerative diseases has not been systematically studied. Three hundred ninety-two individuals with probable AD, 119 patients with the behavioral variety of frontotemporal dementia (FTD-bv), 101 patients with primary progressive aphasia, 24 subjects with semantic dementia, 18 subjects with corticobasal degeneration, 8 patients with progressive supranuclear palsy, 36 individuals with probable Lewy body dementia (DLB), and 26 subjects with Parkinson disease (PD) were the participants of this study. On the basis of a semistructured interview with both patients and their reliable caregivers, MIS was identified in 15.8% of cases with AD, 16.6% of patients with DLB, and in 8.3% of individuals with semantic dementia. The most frequent form of…
