17th Year of School: Did It Make a Difference?

In 1972, Britain rolled out an education reform that added an extra year of schooling, making it 16 years in total. This change set up a unique experiment for researchers to compare the brain health of adults who got that extra year with those who didn't. Surprisingly, a study led by Nickolas Judd and Rogier Kievit from Radboudumc in the Netherlands found no difference in brain structure decades later. They examined MRI scans of over 30, 000 adults taken about 46 years after they finished school. The expectation was to see some benefits, but the extra year didn't leave a lasting impact on brain health. Think of it like exercise: changes might be noticeable immediately, but they might not last a lifetime. So, is there a direct link between education and a healthy aging brain? Maybe not as straightforward as we believed.
