Cortical thickness- It’s not just when but where
MRI brain imaging has opened up new vistas for understanding child development including how cortical thickness is involved with ADHD. One discovery is that to understand the brain in ADHD we have to think in four dimensions–it’s not just the location, or volume or activity of brain regions, but when in development the brain develops.
For example, one large study found that by adulthood, the cortical thickness pattern was the same in individuals with high and low IQ. However, that pattern was achieved at a different age by those with higher IQ. A related study found that by young adulthood, the cortical thickness pattern is the same for ADHD and non-ADHD children–but again, the pattern was reached at different points in development. The trajectory was different.
It is not just how the brain looks but how it got there that matters – for ADHD and other conditions. We and other research groups are now studying which aspects of brain development are associated with improvement in ADHD. Read more in my book, Getting Ahead of ADHD.
