DS7 has the organizational problems I mentioned, and also has sensory issues as well as difficulty sitting still and/or paying attention -- when he's not interested.
I've been really proud of him with dealing with sensory issues. He wears a uniform to school and as of a certain date of the school year must wear uniform pants instead of shorts. It is SOOOOOO hard for him to wear pants, but he is now able to talk himself through it to a certain extent -- he can make it through the school day in pants. He's a hoot when he gets home. He literally rips off his pants as soon as he's through the door, and races to put shorts on instead. Nobody had better get in the way, or they'll be run over. lol
