Scholes also revealed he was once dropped by former United manager Sir Alex Ferguson as he attempted to deal with Aiden’s diagnosis privately, having initially kept it a secret.
“I never got a break from it, even when playing – it was very hard in those days,” said the 50-year-old.
“I don’t think they diagnosed it until he was two-and-a-half years old. But you knew early something was wrong, but then you get the diagnosis, and I’d never heard of it.
“I remember the first time after it, we were playing Derby away and I just didn’t want to be there.
“I remember the manager dropped me the week after, and I hadn’t told anyone. I ended up telling them a few weeks later, as it was quite hard.
“Even now, I don’t want sympathy or anything. I just thought, even if I did speak to someone about it, it’s not going to help Aiden.
“The big concern now is, because you’re getting a bit older, what happens when you’re not here? That’s the thing that’s now on my mind all the time.”
