The best analogy I can make is that dealing with such kids is like taming a feral cat. Due to infirmities of mind, such kids lack the normal development of executive control that is part of growing up for human children.
Over time, from a low standard, such kids tend to gradually learn impulse control through coaching and by developing self-discipline. The lure is to be able to return to be with other kids and take part in class activities of their own accord. In short, with such kids, carrots and treats, patience, praise, and sympathy work better than sticks and confrontation.
My very limited knowledge of special education kids is that such an approach works. My mother was a founding member of a women's group that raises funds for a Catholic special education school. And the school used the alternative approach, which now has increasing academic support.

That would be a great accomplishment. So many adults with high intelligence never achieve that.
