"Correlation" is the key word here. I think it's really important to keep in mind that a lot of people with ADHD have childhood trauma because of how adults responded to their ADHD symptoms. In my case, I have plenty of trauma, almost all of which was the direct results of adults shaming and criticizing me for traits that turned out to be due to ADHD. If your ADHD makes it impossible for you to focus in school, and the adults in your life shame and yell at you every day because you can't focus in school, you're going to have both trauma and ADHD. There's also a solid chance you'll end up with some anxiety and depression. All we know is that a) there's a correlation, b) lots of people with ADHD don't have severe childhood trauma, and c) it's a huge stretch to assume that every person with ADHD is repressing severely traumatic childhood events and never finding out about it. I think it's potentially plausible that generational trauma might have an epigenetic impact, but we'd need a lot more data to know that.
