Managing emotions better could prevent pathological aging

The neuronal connections of the older adults show significant emotional inertia: negative emotions modify them excessively and over a long period of time, particularly in the posterior cingulate cortex and the amygdala, two brain regions strongly involved in the management of emotions and autobiographical memory. These results indicate that a better management of these emotions — through meditation for example — could help limit neurodegeneration.
