If being raised away from humans effects a person to behave in a certain way for the rest of their lives, and most are incapable of changing it ever even after being rescued, then how much of neurodiversity (autism, ADHD etc) are shaped by the environment that we grow up in?

How might it permanently effect a person born and raised in luxury vs in a modestly comfortable setting? Makes me wonder, if we really can't change some things about ourselves
