The IQ was studied in 50 children with CH. Normal distribution of IQ was found in patients detected by neonatal screening. Close relationship was observed between subnormal IQ values (less than 90) and undetectable serum Tg levels (less than 0.3 ng/ml). The intellectual outcome in children with CH depends considerably from the intrauterine hypothyroidism.
