Wow - this sounds somewhat similar to my son. He is just over 3 and was diagnosed with PDD about 1 1/2 yrs ago. We just got back the analysis of his hair sample: His aluminum and potassium levels are off the charts and he has very high levels of antimony, silver, sodium, vanadium, bismuth, manganese and zinc. His mercury and lead levels are normal.
We are looking into chelation now. Any thoughts. Thanks.
