Influence of Oxidative Stress and Nutrition Biomarkers on the Cognitive Decline Evolution in Alzheimer Disease (GERIOX)

29. april 2021 opdateret af: Hospices Civils de Lyon

According to several reports, the oxidative stress and the nutrition could have an impact in the Alzheimer disease.

The association of these two parameters measurements and the cognitive impairment decline could help in a predictive diagnosis of cognitive decline evolution in patients presenting cognitive disorders.

This is a monocentric prospective "routine care" clinical trial on patients showing cognitive troubles especially memory complaints.

The objective is to demonstrate a correlation between oxydative stress and nutrition biomarkers and the clinical evolution of patients complaining of cognitive impairments.

The neuropsychologic data collection (the mini mental Status Examination (MMSE), the clock test, the Grober-Buschke test (FCSR-IR), the executive function evaluated by the Trail making test, and the medical imaging (by magnetic resonance imaging (MRI) or tomography in case of MRI contraindication) will be realized during the study inclusion phase in the usual intake of patients. Whole blood samples for the oxydative and nutrition biomarkers measurements will be taken at the study inclusion day during the stay at the Day hospital dedicated to the routine intake of patients issued from the memory consultation.

In this study, the principal evaluation criteria will be the MMSE score evolution during the 60 months of the patients follow-up, measured during the routine visits scheduled approximately every 6 months, according to the french national authority for health recommendations. It will allow evaluating the correlation between the cognitive decline evolution measured by MMSE during the Alzheimer disease or related diseases method during the 2 years follow-up, and the oxydative stress blood markers.
