Aphil - I do not find your post argumentative at all. Actually I love discussing this stuff.
The point I'm making is that a lot of people are finding that their "anxiety disorder" actually is caused by a thyroid problem. I don't think a lot of people realize that a thyroid problem can cause anxiety. I think maybe some have heard that hyperthyroidism may cause some anxiety, but I am running into people left and right that are finding they actually have a thyroid problem, once they have the correct thyroid tests run - not just the TSH which can be very unreliable.
My son had terrible anxiety. Once his thyroid problem was found he was started on Armour Thyroid and it took him getting up to 4 grains (240 mgs) before we noticed much improvement. He now takes 5 grains (300 mgs) daily and is doing really well. The difference in him, in his anxiety, etc. is almost unbelieveable - actually I don't think I could believe it unless I was seeing this with my own eyes. Both his doc and counselor agreed that his thyroid problem was contributing to his anxiety, but it was so bad that neither felt he would be able to get off the psych meds and simply take a T4/T3 thyroid med - they had never seen anyone so severe be able to get by with only the thyroid med. Well they are both now pleasantly surprised and amazed at how well he is doing on just the Armour Thyroid!!!!!
I have 2 file boxes full of info on thyroid problems and psychiatric problems as it has become my hobby/passion

and I could share all sorts of info and articles, but let me just share this recent one posted at bellaonline.com by a wife & husband that found his anxiety was caused by his thyroid problem (just as my son's was and many many others).

Anxiety and Depression Symptoms in Thyroid Disease
The message that I am trying to get out is that everyone presenting with any sort of psychiatric problem should first have their thyroid tested, by running the correct tests, to at least make sure that they don't have a thyroid problem causing their mental problems.
I was told for 20 years that my thyroid was "fine" even tho I had many physical symptoms - but the dang TSH would not catch the problem. Thankfully now my son's doc is also treating me and I am also taking 5 grains of Armour and feel that I have my life back!
I'm just trying to share a little of info that I have found. This info could have saved us years of suffering and challenges.
hugs,
Cathy
