Here's the original title (was too long for HN): What if ADHD risk isn’t fixed at birth, but shaped by how early environments interact with a child’s sensitivity?

I feel like at least personally, my ADHD is aggravated by other stress factors in life. I had neuro divergent friends and we were bad for each other. We would hinder each other's focus and discipline.

This sounds similar to the theories Gabor Maté has on the topic. He’s written some books on the topic.

He sees ADHD has a trauma response from sensitive kids in a stressful home. A child can’t physically leave the stressful situation for actual fight or flight, so the mind checks out.
