12. Clinical and subclinical maternal hypothyroidism and their effects on neurodevelopment, behavior and cognition
ABSTRACT Clinical and subclinical hypothyroidism are the most common hormonal dysfunctions during pregnancy. Insufficient maternal thyroid hormones (THs) in the early stages of pregnancy can lead to severe impairments in the development of the central nervous system because THs are critical to central nervous system development. In the fetus and after birth,
