What is the reason for children’s slow intellectual development?

Children's intellectual developmental delay can be affected by many factors, so any problems that may affect the child's intelligence should be taken seriously. Among them, genetic factors can be said to be more obvious. At the same time, endocrine growth hormone or some viral infections of the mother during pregnancy may also cause the child's intellectual development to be slow.

1. Genetic factors: The characteristics, constitution, potential, and limits of a child’s growth and development are all restricted by the genetic factors of their parents. The genetic information of race and family has a profound impact on the next generation, such as skin, hair color, facial features, etc.; genetic diseases, whether chromosomal abnormalities or metabolic defects, have a significant impact on growth and development.

2. Endocrine growth hormone: Human growth is mainly regulated by various hormones, especially growth hormone and sex hormone. When growth hormone is deficient, symptoms of short stature will appear; sex hormones can cause bones to fuse earlier, affecting growth and development, so adolescents who enter puberty early will affect their final height growth.

3. Gender: The growth and development of boys and girls are different. Generally speaking, the average height and weight of girls are lower than those of boys. Girls' puberty starts about two years earlier than boys'. During this period, girls' growth and development are faster, but boys' puberty lasts longer than boys', so boys will eventually be taller than girls. Therefore, when analyzing growth and development, boys and girls should be studied separately.

4. The condition of the pregnant mother: The growth and development of the fetus in the mother's body is affected by many factors such as the mother's growth environment, mood, nutrition, and disease. If the mother is malnourished, it may cause miscarriage, premature birth, and delayed physical and brain development of the fetus. If the pregnant mother becomes ill in early pregnancy, it can directly cause fetal malformation.
