Congenital hypothyroidism (CH) results from a failure of the thyroid glands to produce thyroid hormones in adequate amounts. The condition can easily be treated with daily doses of thyroid hormones but clinical diagnosis is difficult to establish and the disease may continue unrecognized for a long time causing irreversible brain damage. However, increased thyroid stimulating hormone (hTSH) and decreased thyroxine are clear signs of CH, which have led to the establishment of large scale screening programs.
