Hello

Cretinism is a disease caused by hypothyroidism. It is either due to extreme iodine deficiency, i.e. endemic cretinism or due to decreased synthesis of thyroid hormones, i.e. sporadic cretinism. It is typically diagnosed during infancy or childhood, however, the best preventive strategy is the screening of neonates.

All the best
