Do some of y’all have genetic ADHD?

[u/Mamahei2]

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)

I thought it was all genetic but I'm the second ever person to be diagnosed my younger brother was the first. My moms side is from Greece so they didnt really have any reliable testing but my mom and grandpa also probably have/had Adhd
