my grandma was on the spectrum (died in her late 90s), my dad is on the spectrum, my mom has adhd, all 3 of my brothers have different levels of autism and adhd, i have autism and adhd. ITS GENETIC
Me and my mom and brother all have veryyy similar autisms ( similar symptoms) to varying degrees part could of course be socialization but genes play a big part of it yk
