This is from the book I co-wrote, TRANSFORMING ADHD (I’m allowed to post some of the book). I hope you find it of use. It’s less glamorous-looking than I’d like, but if you knew my schedule, you’d understand. Besides, it’s all about the content, right?

The latest research shows a strong correlation between ADHD and PTSD. Perhaps they should screen persons with ptsd for ADHD and vice versa?

Hi, Kate,
Fascinating, right? It’s still early to act though. As the authors note, theirs was the first to find what they found. We need replication. Also, there’s a question to be answered about how specific their results are to ADHD: “Perhaps our findings, for example, are not specific to ADHD, as studies have also identified impaired fear circuitry in other psychiatric disorders.”
