Clinical Trial Summary

The goal of this clinical trial is to compare conventional clinical data collected as part of usual practice with data collected by the two digital tools to help diagnose major and minor neurocognitive disorders in elderly people consulting a memory center for cognitive complaints. The main question[s] it aims to answer are: - Is it possible to create a classification between the different intensities of cognitive impairment? - Is it possible to create a diagnostic tool consistent with the reference diagnosis? Participants will be asked to complete a series of cognitive and fine motor tasks, and will be given questionnaires on their lifestyle and medical history. They will be asked to wear a connected watch for 1 week. There is no comparison group.

Description:

Alzheimer's disease, which leads to dementia, has an insidious onset and a slow, gradual progression. After a completely asymptomatic phase that can last several years (prodromal stage of the disease), the first signs consist of a moderate deterioration in performance in one or more cognitive domains, such as memory, attention, planning or other cognitive faculties. Clinically, this is referred to as mild neurocognitive impairment (MCI) due to Alzheimer's disease. The progression is towards a major neurocognitive disorder, in which cognitive dysfunction progressively increases, and the patient becomes dependent for activities of daily living. Early detection of the disease, and specifically of this mild neurocognitive disorder, is crucial for a window of intervention prior to dementia. The investigators propose to evaluate a tablet version of a manual dexterity test that the investigators have already been able to test, in combination with assessments already established in the clinic and physiological data collected by a connected watch, to help diagnose neurocognitive disorders by confronting them with the clinical data that are the reference. The investigators propose this multicenter observational study with a diagnostic aim. The study will involve 150 elderly people consulting one of the two participating memory centers. Three groups will be formed: 50 people with no cognitive dysfunction, 50 with a mild neurocognitive disorder, and 50 with a major neurocognitive disorder linked to Alzheimer's disease. These groups will be formed on the basis of the reference diagnosis established by the memory consultation teams, and the results of the patient's neuropsychological and medical assessments. The investigators will retrieve data from the medical record to classify cognitive status.
