Maternal thyroid-stimulating hormone (TSH) concentrations in early pregnancy are associated with the volume of grey matter in offspring at 9-12 years of age, according to a novel study finding.
The Dutch prospective study of 1981 mother-child pairs showed that both low and high maternal TSH influences neurodevelopment in the fetus in a small window between eight and 13 weeks’ gestation.
