Can you diagnose ADHD with a brainscan?

Today, we tackle an interesting, and surprisingly complex question posed by a friend: Why can’t we just diagnose ADHD with a brain scan?
Join us as we break down the science behind ADHD, discussing how structural and functional brain differences contribute to symptoms—and why a brain scan alone isn't enough for diagnosis.
