While I would not consider myself "cured" of anything, I have found that Iodine..or the lack thereof...causes me to have panic and anxiety attacks. This is a recent (within 3 months) development for me as I have never had panic and anxiety attacks prior. And although I now take Kelp in a Thyroid supplement (for my newly developed Hypothyroidism), My Iodine test (painting a 2x2 in sq on my abdomen) still shows a regular Iodine insufficiency. Interestingly, I also drink protein shakes that contain 30% FDA Iodine each. I drink 2-3 of these each day. Yet, my Iodine is consistently depleted.
