Can cognitive and behavioural disorders differentiate frontal variant-frontotemporal dementia from Alzheimer’s disease at early stages?
Open accessAbstract
Frontal variant‐Frontotemporal dementia (fvFTD) and Alzheimer′s disease (AD) patients matched for severity of dementia at the Clinical Dementia Rating (CDR) received neuropsychological testing in order to explore if the dysexecutive disorder might characterise fvFTD at early stage, when AD is dominated by the episodic memory defect. We also determined if the behavioural syndrome was more severe in fvFTD than AD, and if specific patterns of behavioural symptoms could differentiate the two types of dementia, using the Neuropsychiatry Inventory (NPI). AD patients performed worse than fvFTD not only in memory but also in executive tasks. Apathy and eating disorders proved to be more severe or frequent in fvFTD even if the two groups did not differ in the total NPI score. CDR score significantly correlated with the NPI score in fvFTD and with the MMSE in AD. Our data confirm that the memory disorders may differentiate the two types of dementia; however, the dysexecutive syndrome is as severe, and even more severe in AD. The severity of the behavioural syndrome is comparable in the two groups but the nature of the behavioural disorders may vary to some extent. We conclude that AD dementia at early stage is a behavioural‐cognitive syndrome, while in fvFTD the behavioural disorders appear when the cognitive deficit is still relatively mild.

Attention and executive deficits are not specific to bvFTD.
“Major deficits in attention (Kipps et al. , 2008) and executive functions (Kipps et al. , 2008; Harciarek and Cosentino, 2013) are often reported; however, these are not specific to bvFTD (Jenner et al. , 2006).”

The available passage is article information and keywords, with no section or page containing findings. Searches for attention, executive deficits, and whether these deficits distinguish bvFTD from Alzheimer’s disease returned no substantive passage, so our copy does not establish the claim.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
