Well, then my symptoms were so subtle they did not exist. I was not the least overweight as a child, no brittle hair no nothing. I still had ADD. Also I have several friends with OTHER autoimmunity AND ADD/ADHD and they don't have thyroid problems. I think ADD is more complex than thyroid stuff.

My mom, who also has ADD, had hyperthyroid, but she was fine until I was 10 years old.
