What this trial studies

This observational study aims to investigate the determinants and natural history of brain aging in a representative sample of 2000 individuals aged 55 and older from the Bordeaux metropolitan area. It employs molecular epidemiology methods to explore various factors, including nutrition, that may influence cognitive aging and the onset of dementia. Participants will undergo a series of assessments, including questionnaires and biological sample collections, to gather comprehensive data on their health and environmental exposures. The study seeks to enhance understanding of cognitive aging and inform prevention strategies.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 55 to 80 living in the Bordeaux metropolitan area who are willing to participate in biological sampling.

Not a fit: Patients under guardianship or those unable to provide consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved prevention strategies for cognitive aging and dementia.

How similar studies have performed: Previous population-based cohorts have successfully contributed to understanding aging and dementia, indicating a strong foundation for this approach.
