Structural brain network efficiency and cognitive processing speed in healthy aging

Background To test the hypothesis that structural brain network efficiency relates to cognitive processing speed and executive function, we computed structural brain networks of 2,278 healthy adults and conducted graph theoretical analyses. Method 2,278 healthy adults from the cross‐sectional Framingham Heart Study, aged 26‐91 years, were included. We used the trail making test (TMT) parts A and B to assess processing speed. To assess executive...
