Low levels of body-regulating hormones produced in the neck thyroid gland of pregnant women during the first trimester, could interfere with brain development of the foetus, says a study conducted by NYU School of Medicine. The researchers believe that disruptions in hormone production, or hypothyroidism, makes children susceptible to attention deficit/hyperactivity disorder (ADHD). T
he study, submitted to the American Journal of Perinatology, indicates that children whose mothers were diagnosed with hypothyroidism shortly before or during the early stages of pregnancy are 24 percent more likely to have ADHD than children with mothers without this problem. “Our findings make it clear that thyroid health has a much larger role in fetal brain development and behavioral disorders like ADHD than we previously understood,” says study lead author Morgan Peltier, associate professor at NYU Winthrop Hospital.
