Polyvagal Theory and ADHD

I've recently been learning about polyvagal theory at the suggestion of my therapist, and through that research have seen that it is connected to trauma, Autism, Schizophrenia, and many other mental health disorders (I am not diagnosed with any of these disorders, nor do I know much about them). As it stands, I have a theory that I'm playing with about how this connects to ADHD as well. If I'm wrong, please feel free to correct me in the comments.
