Clinical Trial Summary

Early in its development, Alzheimer's disease causes not only brain damage affecting different regions of the brain, such as the entorhinal cortex, the anterior cingulate cortex, and the prefrontal lobe, but also a cognitive deficit affecting several functions, such as episodic memory, executive functions, or working memory. Although these different areas and functions are involved in the decision-making process, few studies have focused their research on this subject in the context of Alzheimer's disease. However, a 2008 study showed an early decline in decision-making skills in the disease, but did not link this deficit to cognitive impairment. In addition, decision-making is generally assessed using a test called the Iowa Gambling Task (IGT), which, despite its many advantages, does not have established ecological validity.

In the context of pathology, however, it seems essential to evaluate decision-making in relation to daily life, especially since a deficit in this process would have considerable repercussions on quality of life.

In this study, the investigators seek to better define the disorder by decision-making in early Alzheimer's disease, to understand the links between them with the deficit of other cognitive functions, and to highlight the the consequences that this decline has on patients' daily lives.
