Scientists demonstrated, through brain imaging and psycho-cognitive evaluations conducted over several years on a community-based cohort of elderly people, that certain personality traits protect brain structures against neuro-degeneration and Alzheimer’s disease. Among them, people who are less agreeable but with a natural curiosity and little conformism show better preservation of the brain regions that tend to lose volume, both in normal aging and in Alzheimer’s disease.
The results are surprising: people who are unpleasant, who are not afraid of conflicts and who show a certain anti-conformity have better protected brains. In addition, this protection takes place precisely in the memory circuits that are damaged by Alzheimer’s disease.
