My eldest son has a touch of aspergers. I noticed big difference after he was given iodine, quit fluoride. His teachers, neighbors, friends: even more.
I noticed the skills in math and other subjects at school skyrocketed (posted here before), so did the teachers of course. My neighbors, friends; noticed that he looked up more, said hello etc.
Now, at his best, is an entertainer in a group, make people roll over the floor with his wit. Still does not like to buy new clothes:)
Barnes test. As Iodine may have an impact on body temperature. Has nothing to do with the temperature outside. A few adhd boys I worked with a few years ago had a very low body temperature; down to 35C. (Brain is more than anything influenced by temperature) After Iodine and company they increased their performance as the temperature went up closer to normal. A few links, if you haven't read it;
