I am having this same thought. I was diagnosed with PCOS a few years ago and recently saw a shrink for some other stuff and it turns out I have ADHD. Apparently people with ADHD have a decrease in dopamine receptors in the frontal lobe of
the brain which is also is the place where glucose metabolism is dealt with (I
don't know the specific pathophysiology on this one). But one of the main issues with PCOS is insulin resistance wich of course is glucose metabolism. I really believe there is a connection here.
