General Question/Discussion Do some of y’all have genetic ADHD?

Literally my mom, my sister, my niece, my nephew, and I all have ADHD as well as me and my mom having autism.

Edit: I’m more so talking about ADHD being a dominant trait (at least for my family)

ADHD is more heritable than height or intelligence. The largest twin study found heritability approaching 80%. Siblings of someone with ADHD have a 5-7x higher chance of having ADHD. If a child has ADHD, there’s a 47% chance one of the parents has ADHD. It’s very genetic.
