50 4 Full Breakdown

Summary

Story summary

A University of California, Irvine study finds aging alters brain geometry, and this change is linked to memory and reasoning decline.
Inferior and anterior regions expand while superior and posterior regions compress.
These changes may stress the entorhinal cortex, a memory hub, elevating Alzheimer's risk.
The study suggests brain geometry could be an early biomarker for dementia risk.
