That's just it - everything in ADHD occurs in neurotypical land. Just with ADHD it's disruptive to your life on a regular/near-constant basis.
If you have multiple of these behaviours that occur frequently/are regularly disruptive, that's a good sign you may have a form of ADHD.
Being disruptive of your life is a significant part of the diagnosis.
The moving leg thing is a symptom of H in ADHD: hyperactive. Can't sit still. I have a friend in his 60's who does this, and has since he was a kid. He stumbles over his words, and always has. Total hyperactive type, though he's never been diagnosed.
