Is Your Brain Shrinking? – Dr.Berg On Brain Health & Brain Atrophy

Fossil Comparisons: Studies comparing brain size in Homo sapiens fossils from different eras suggest a decrease in volume over tens of thousands of years [1].
Modern Brain Scans: Advanced imaging techniques like MRIs allow researchers to measure brain volume in living people. This helps track brain size changes in populations over time [1].
It’s important to remember that brain size doesn’t necessarily equate to intelligence. Our understanding of the brain is constantly evolving, and researchers are looking at how brain efficiency and organization might be more important than overall size [3].
