This project aims to study on one hand the early mitochondrial alterations, common or specific, occurring in peripheral cells of patients with Alzheimer's disease or related dementia and, on the other hand, identify the metabolomic biomarkers that may be at the origin of mitochondrial disturbances associated with the disease. This will be the first study combining functional analyses of mitochondria and exploratory metabolomic assessments in the same cohort at early stages of the disease.
