Thyroid hormones are important regulators of early brain development and lack or excess of maternal thyroid hormone in early pregnancy may interfere and impair fetal brain development. Outcome of pregnancies prenatally exposed to maternal thyroid dysfunction is therefore a matter of concern. The potential benefits and risks associated with routine testing for undetected thyroid disease in pregnant women is debated, and the degree of thyroid abnormality relevant to screening and intervention remains unsolved. We investigate the association between maternal thyroid function and neuropsychological performance of children who at age five participated in an extensive neuropsychological testing program.
