Brain mass: Shrinkage in the frontal lobe and hippocampus, which are areas involved in higher cognitive function and encoding new memories, starts at around the age of 60 or 70 years. Cortical density: This refers to the thinning of the outer-ridged surface of the brain due to declining synaptic connections.

Can brain shrinkage reversed?
It’s not possible to reverse brain atrophy after it has occurred. However, preventing brain damage, especially by preventing a stroke, may reduce the amount of atrophy that you develop over time. Some researchers suggest that healthy lifestyle strategies could minimize the atrophy that’s normally associated with aging.
At what age is your brain the sharpest?
