What are the causes of mental retardation

summary

Not long ago, I went to visit my friend's child. I found that the child was afraid of strangers and didn't like to talk. My friend told me that he took his child to the hospital two days ago. The doctor confirmed that the child might be mentally retarded. My friend was in a low mood after knowing the doctor's diagnosis, but he didn't give up on his child. Today, I'd like to talk about the causes of mental retardation.

What are the causes of mental retardation

First, genetic factors are one of the main causes of severe mental retardation. In developed countries, mental retardation caused by genetic diseases accounts for more than half of the total number of severe mental retardation. If a pregnant woman is infected with rubella virus, influenza and other viral diseases in the first four months of pregnancy, it will do great harm to the fetus and infant, and cause congenital malformation and mental retardation.

Second: congenital folly syndrome, also known as Down's syndrome, is caused by chromosomal abnormalities. Idiopathic thyroid disease is also known as congenital thyroid insufficiency. Due to the abnormal development of thyroid, it can not synthesize thyroxine, which affects the development of brain. Phenylketonuria is due to enzyme deficiency, the intake of phenylalanine metabolism is blocked, resulting in brain cell dysfunction. Cat barking syndrome is caused by a chromosomal problem in the body.

Third: early social isolation, emotional deprivation, lack of maternal love, no one to take care of, cultural isolation, inappropriate teaching methods can affect children's intellectual level. In families with high social and economic status, stable family structure and well-educated mothers, children's intelligence level is higher than those with poor related conditions. Other factors, such as large family, many children, short birth interval, twins and parents' divorce, all have a direct impact on children's intellectual development.
