I was just diagnosed at almost 50 and it was totally worth it. I had to pay for the full assessment, but it was worth doing because it highlighted the problem areas for me. I am starting with a very low dosage of medication and everyone says they can see the change in me. The other treatment options will follow, but it is a great start.
My Physician told me that very few adults have it and most people grow out of it (Not True, we all just learn to cope better). Just because your physician is out of touch with current research, don’t let it discourage you from getting another opinion.
