What this means
Researchers plan to track brain aging in 2,000 people aged 55 and older. They will look closely at diet, which they call a promising area for prevention. This is a study that is still signing up people, so no results exist yet.

Registry 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.
