> Is there any evidence ADHD is genetic? The only connection I've read about is that parents who are diagnosed with ADHD are more likely to have their children diagnosed with it, but that itself is not evidence of a genetic trait. Short answer: yes, there's lots of evidence of genetic factors. One reason this isn't better understood is that a close relative can have undiagnosed ADHD, so people don't see the family ties. And also because it's stigmatized in some families, it's like a "don't ask, don't tell" situation. I mentioned a great podcast by Dr. Andrew Huberman, a Stanford neuroscientist earlier in the thread that mentions how the genetics of ADHD works [1]: [1]: https://news.ycombinator.com/item?id=33960655 https://news.ycombinator.com/item?id=33960655
