Healio (11/25, Monostra) reports a study suggests that “women who have thyroid dysfunction both before and during pregnancy may have increased risk for having a child diagnosed with autism spectrum disorder.” Researchers observed that “women who had both chronic and gestational thyroid dysfunction had higher risk for offspring with autism spectrum disorder than women with normal thyroid function. Similarly, women with both chronic and gestational hypothyroidism had increased risk for children with autism spectrum disorder than women with normal thyroid function.” They noted that “each additional trimester of thyroid dysfunction during pregnancy raised the risk for offspring with autism spectrum disorder for women with gestational hypothyroidism only and those with both chronic and gestational hypothyroidism. The risk for having offspring with autism spectrum disorder was highest among women who had gestational hypothyroidism through all three trimesters of pregnancy.” The study was published in The Journal of Clinical Endocrinology & Metabolism.
