Biobank and Brain Health in Bordeaux.

Summary

B cube is a new generation cohort to study the determinants and natural history of brain aging, using molecular epidemiology, in a representative sample (N=2000) of the general population from the age of 55 (the approximate age of onset of the first cognitive disorders and a target population particularly receptive to prevention messages). Special interest will be given to nutrition, a promising environmental exposure for prevention.
