Abstract

Although neonatal thyroid screening programs have been of value in preventing cerebral damage, it is still controversial whether patients with congenital hypothyroidism achieve normal motor and cognitive skills. We studied the motor and cognitive skills of 72 children with early-treated congenital hypothyroidism and 35 control subjects at the ages of 7 1/2 and 9 1/2 years. The relative influence of cause, blood thyroxine concentration at the time of screening, and age at the start of thyroxine replacement therapy on motor and cognitive development was investigated. Despite having received treatment at a mean age of 23 days, children with low neonatal thyroxine concentrations (< 50 nmol/L) at screening, particularly children with thyroid agenesis, had significant motor problems and borderline intelligence scores as late as 9 1/2 years of age. Balance and gross motor functions seemed to decline between 7 1/2 and 9 1/2 years of age, whereas language and memory functions seemed to be maintained. Significant correlations between the start of therapy and both motor scores and performance IQ scores at the age of 7 1/2 years in children with severe hypothyroidism show the importance of early treatment for these patients.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
