Well I didn't know they were signs, but here's what I had trouble with since I was at school really...
Talking, a lot, fast, have trouble stopping and can tend to blurt out/interrupt.also oversharing.
Distraction, aka daydreaming in school reports. Can't concentrate without hearing all the noises around, dc all chatting at me is maddening.
A bit emotional/ sensitive. React quickly without thinking sometimes.
Procrastinating. Hard to start doing stuff, hard to complete the job.
Get obsessed with something new and exciting till I'm bored with it.
also impulse buying. 
All the books for me.
Forget stuff. All the time. Poor working memory essentially.
Hard to concentrate on someone talking to me. Tend to drift off in thought, look at phone, at someone passing etc. This one drives DH nuts.
Possibly more but that's the first things that came to mind. :) I had no clue until I googled for resources for DS1 struggling at school with focus. Everything came up about ADHD. I was
when I read it.
Tonight I will drink beer. 😂🍻
