Abstract
It can only be ensured that thyroid function is normal when thyroid-stimulating hormone and free thyroid hormones thyroxine and triiodothyronine levels are normal. A hormonal pattern with elevated free thyroxine and triiodothyronine and unsuppressed thyroid-stimulating hormone is very rare, and its main cause is thyroid hormone resistance syndro¬me, a rare genetic entity that can associate symptoms of hypo and hyperthyroidism and whose diag¬nosis requires a high rate of suspicion. In children, the sole or main manifestation may be an attention deficit hyperactivity disorder. We present a family characterized by the initial diagnosis of twin sisters at 20 months of age.
