ARREOLA-RAMIREZ, Gabriela et al. Neurodevelopment in infants with congenital hypothyroidism antecedents. Perinatol. Reprod. Hum. [online]. 2005, vol.19, n.3-4, pp.141-151. ISSN 2524-1710.

Introduction: Follow-up studies of hypothyroid infants who received early treatment evidence the presence of the same IQ vs. the general population. Material and methods: Retrospective cohort study. Twenty-four hypothyroid infants detected in neonatal screening were compared to a control group. The newborns were assessed from six months to seven years based on Bayley's infant development scales (ID), the Terman-Merril IQ (Cl) and the learning aptitude of the heard of hearing with the Hiskey-Nebraska test (CA). Results: Twenty hypothyroid infants showed a normal or high Cl or ID. One of the infants with a ID result below the mean, two with an Cl below the mean, one hearing impaired infant with low learning aptitude. No differences were found vs. the control group. The use of ototoxic medications, prematurity and hyperbilirubinemia explain the low coefficients between the hypothyroid individuals and the control. Conclusions: The Cl and the ID results in the hypothyroid group who received early treatment showed no difference vs. the control group.
