The food exposome of brain aging and dementia: epidemiological approach


As a director of research at INSERM (the French National Institute for Health), Cécilia Samieri leads a group on the “exposome of brain aging and dementia” in the Bordeaux Population Health research center. She studies the epidemiology of brain aging, with the aim of understanding how the environment influences the etiology of dementia, developing original approaches to address lifestyle and brain health with a holistic vision, from diet patterns to molecular markers of the exposome. Trained as a veterinary and then as a neuro-epidemiologist in Bordeaux and as a Fulbright post-doctoral fellow at Harvard School of Public health in Boston, she leveraged large French and US cohorts to evidence associations of healthy diets and optimal cardiovascular health, with healthy brain aging. She served as academic co-chair of the Alzheimer’s Association's Professional Interest Area group on Nutrition and Metabolic Diseases from 2019 to 2021. In 2022 she has set up a new population-based cohort of your seniors after age 55 as a unique tool to evaluate, with high-throughput molecular and imaging-based epidemiology, the exposome and early signs of neuropathology. The overarching goal is to inform next-generation public health policies, integrating behaviors with contextual factors for the precision prevention of cognitive aging.
