Not sure. Would an ADHD person be happy harvesting wheat hour after hour, day after day? Or washing clothes in the river? There are way more creative occupations in our days.
It is really a sign of failing schools if they can not attend to kids who are different from those who sit quietly and do not talk. You need to stop relying on schools and attend to your kids yourself, just like you do other mitzvos – putting tefilin, making a sukkah, having children.
