Métacognition et jugement du danger dans la maladie d’Alzheimer : corrélations ou indépendance ?

Abstract : Context : The aim of this study is to analyse the impact of metacognitive impairment on danger assessment in Alzheimer's disease (AD). To do so, we structured our research around three successive hypotheses: Is overall metacognition impaired in AD? Is the judgement of danger deficient in AD? Does the lack of metacognitive appreciation have an impact on the patient's endangerment?
Method : An evaluation protocol was proposed to 18 participants (9 AD patients and 9 healthy subjects). Three meetings were set up to assess metacognitive knowledge, metacognitive skills, judgement of danger and cognition, by means of tests and questionnaires. In parallel, questionnaires were given to relatives to determine a degree of anosognosia.
Results : Although the patients were able to objectify cognitive difficulties, they fell short of the reality described by their relatives. Moreover, unlike the control population, patients do not adjust their metacognitive knowledge to the task they are performing. There was a significant difference between the two groups in the results of the danger judgment tests. However, metacognitive self-evaluations were found to be independent of success in hazard judgement tests.
Conclusion : Overall metacognition is affected in AD. The ability to judge danger is also impaired. Nevertheless, this study did not show a correlation between metacognitive deficit and hazard assessment in AD.
