Education has been related to various advantageous lifetime outcomes. Here, using longitudinal structural MRI data (4,422 observations), we tested the influential hypothesis that higher education translates into slower rates of brain aging. Cross-sectionally, education was modestly associated with regional cortical volume. However, despite marked mean atrophy in the cortex and hippocampus, education did not influence rates of change. The results were replicated across two independent samples. Our findings challenge the view that higher education slows brain aging.
教育与各种有利的终身结果有关。在这里,我们使用纵向结构 MRI 数据(4422 个观测值)检验了一个有影响力的假设,即高等教育转化为较慢的大脑衰老速度。在横截面上,教育与区域皮质体积有一定的关联。然而,尽管皮质和海马体的平均萎缩明显,但教育并没有影响变化率。这些结果在两个独立的样本中得到了复制。我们的研究结果挑战了高等教育减缓大脑衰老的观点。
