Saliva collection and nasal or nasopharyngeal swab clinical trials

Biobank and Brain Health in Bordeaux.

This study, called "B cube," looks at how our brains change as we get older, especially from age 55. Researchers want to understand why some people's memories and thinking skills decline and how to prevent it. They are studying 2000 people in Bordeaux, France, focusing on things like diet and overall health.
