Can social anxiety cause ADHD people to stop fidgeting and remain still in public?

If someone has social anxiety disorder and also AD(H)D, and would normally fidget and move around constantly while alone, could their fear of being criticised for their movements while in the prescence of others cause them to remain still or ‘paralysed’?

It certainly could.
ADHD is not a distinct disorder, some people can have it worse than others, and some can have tendencies,etc. In other words, it’s dimensional.
social anxiety is the same thing.
So it’s just a question of which is stronger and how that person reacts when nervous. Some people shut down, others get restless and fidgety.
You don’t have to assume that people with ADHD are categorically different than normal people, it’s only a difference of degree.
