Low and high maternal thyroid hormone levels during pregnancy may affect infant's IQ

A new study finds that not only low but also high maternal thyroid hormone levels during early pregnancy may significantly lower the infant's IQ later in childhood. The study results, which will be presented Thursday at the Endocrine Society's 97th annual meeting in San Diego, suggest that the common practice of treating pregnant women who have mild thyroid hormone deficiency may pose unexpected risks to the developing baby's brain.
