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 about 80% heritable. So it’s genetic nearly always.

I also found this article about the heritability of executive functioning interesting -

Individual Differences in Executive Functions Are Almost Entirely Genetic in Origin

From the abstract:

Results indicated that executive functions are correlated because they are influenced by a highly heritable (99%) common factor that goes beyond general intelligence or perceptual speed, and they are separable because of additional genetic influences unique to particular executive functions. This combination of general and specific genetic influences places executive functions among the most heritable psychological traits.
