Qualitative neuropsychological performance characteristics in frontotemporal dementia and Alzheimer's disease.
BACKGROUND Frontotemporal dementia (FTD) and Alzheimer's disease are clinically distinct disorders, yet neuropsychological studies have had variable success in distinguishing them. A possible reason is that studies typically rely on overall accuracy scores, which may obscure differences in reasons for failure. OBJECTIVES To explore the hypothesis that analysis of qualitative performance chara...
متن کاملOrbitofrontal Dysfunction Discriminates Behavioral Variant Frontotemporal Dementia from Alzheimers Disease
Background: Behavioral variant frontotemporal dementia (bvFTD) patients show prefrontal cortex dysfunction and atrophy. Methods: We investigated whether executive function in conjunction with prefrontal cortex atrophy discriminates bvFTD and Alzheimer’s disease (AD) patients efficiently at presentation. Results: AD and bvFTD patients were distinguishable by 89.5% on their performance of 3 execu...
متن کاملPatterns of neuropsychological impairment in frontotemporal dementia.
OBJECTIVE To differentiate frontotemporal dementia (FTD) subtypes from each other and from probable Alzheimer disease (AD) using neuropsychological tests. METHODS Patients with FTD and AD (n = 109) were studied with a comprehensive neuropsychological protocol at first contact. Data were subjected to a principal components analysis (PCA) to extract core neuropsychological features. A five-fact...
متن کاملQualitative Assessment of Verbal Fluency Performance in Frontotemporal Dementia.
BACKGROUND/AIMS Verbal fluency is impaired in patients with frontotemporal dementia (FTD) and primary progressive aphasia (PPA). This study explored qualitative differences in verbal fluency (clustering of words, switching between strategies) between FTD and PPA variants. METHODS Twenty-nine patients with behavioral variant FTD (bvFTD) and 50 with PPA (13 nonfluent/agrammatic, 14 semantic, an...
متن کاملFrontotemporal dementia, semantic dementia, and Alzheimer's disease: the contribution of standard neuropsychological tests to differential diagnosis.
CERAD-NAB (Consortium to Establish a Registry for Alzheimer's Disease-Neuropsychological Assessment Battery) data were compared between 51 patients with frontotemporal dementia, 13 with semantic dementia, and 69 with Alzheimer's disease. There were statistically significant differences between the 3 groups. Compared with patients with Alzheimer's disease, patients with frontotemporal dementia w...
