The Claim
Hippocampal volume declines at a significantly slower rate during early adulthood (−0.191% per year) than in late adulthood (−0.714% per year), confirming a nonlinear trajectory of age-related atrophy that accelerates after age 60 in cognitively healthy adults.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In cognitively healthy adults, the hippocampus shrinks more slowly between ages 20 and 60 (0.191% per year) than after age 60 (0.714% per year), showing that brain atrophy speeds up with advancing age.

As people age, brain cells slowly accumulate damage from normal metabolic processes, and the brain makes fewer new cells after age 60. Before 60, these changes happen slowly, so the hippocampus shrinks little. After 60, the damage builds up faster and new cell production drops sharply, causing the hippocampus to shrink much more quickly.
What the research says
1 studyThe study found that the memory part of the brain shrinks very slowly until about age 60, then starts shrinking much faster—exactly what the claim says.
