AB - Objective: Anosognosia heterogeneously affects cognitive functioning and indeed, at the very onset of
dementia symptoms. This raises the question of accountable predictors of each cognitive impairment. The
objective of this study was to identify the cognitive and non-cognitive predictors of so-called cognitive
anosognosia.
Method: A paradigm based on the discrepancies between performance predictions and actual performance
in the light of the Dementia Rating Scale (DRS) helped distinguish cognitive anosognosia in relation to four
major functions: Attention Initiation-perseveration, Conceptualisation and Memory. Patients achieved a
complete set of neuropsychological tests and assessments of the level of anxiety, apathy and functional
independence.
Results: Significant correlations existed between all cognitive anosognosia scores (AS) and
neuropsychological performance scores of the participants. Similarly, significant correlations were found
between the Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scores
and the Initiation and Conceptualisation AS and between anxiety score and Conceptualisation and Memory
AS. However, the regression models were exclusively cognitive for Attention Initiation-perseveration and
Memory AS. Only the Conceptualisation AS was predicted by a non-strictly cognitive regression model
including the ADL score.
Conclusions: If the different specific cognitive anosognosias are predicted by separate sets of variables, our
results emphasise that dysexecutive impairment plays a major role regardless of the deficiencies considered.
