Introduction
The thyroid is a tiny gland that secretes hormones located in the throat area. Thyroid is crucial for energy in every cell in the body and for normal brain development in utero and especially during the first few years of life. Irregularities in either of the thyroid hormones, T3 and T4, can affect behaviors, the functioning of the nervous system and cognitive development. Raffael Kellman, MD has found that 75% of ASD children had undetected thyroid problems. As many as 7 out of 10 had an underactive thyroid (hypothyroidism). He found a decrease in the conversion from T4 to T3 and an increase of the inflammation markers in the immune system due to the production of immune autoantibodies which suppressed TSH production. He also found high cortisol levels due to the extreme stress of ASD children which also decreased TSH production. Routine measuring of the thyroid by taking the body temperature or measuring the blood TSH (Thyroid Stimulating Hormone), T3, and T4 have been found not to consistently detect problems and abnormal levels in the thyroid. Instead, the TRH (Thyrotropin Releasing Hormone) Stimulation test stimulates the pituitary gland to produce TSH which stimulates the thyroid and produces thyroid hormones. The TRH test has a much more accurate assessment of what is going on with the thyroid. Dr. Kellman has found that by treating the thyroid hormones ASD children can improve language, cognition, hyperactivity, motor function, socialization and gastrointestinal issues.
