Just an opinion - our DS is very moody and has ADHD combined. He takes Quilivant which makes him nicer, but it's a low dose and he still has low tolerance for people and is bossy. However, my husband doesn't have ADHD and is very moody and is very affected by blood sugar even though not hypoglycemic or diabetic. I do believe my husband is highly gifted and he is intense. I think some of this is the gifted mind.
Side note - I have worked in mental health quite a bit, and people with bipolar don't typically cycle multiple times in a day. They do cycle across days and weeks. Typically have a manic period then swing into depression.
Fwiw - my ds 6 is the same, other than he is never super happy off meds. He tends to be more grouchy and touchy. But like his spine!
