Third: there are abnormalities in the fetal period. The first three months of pregnancy is the initial formation stage of the fetal nervous system structure, which is particularly vulnerable to the damage of pathogenic factors, leading to obvious deformities. In the fetal period, maternal infection, abdominal trauma or radiation, hypothyroidism and other endocrine diseases are the causes of mental retardation.
