Causes of autism in children

Children are the flowers of the motherland and the pillars of the future. It is our parents’ greater responsibility to educate and care for them. Nowadays, there are more and more children with autism in various countries, and the incidence rate in modern society is also getting higher and higher. As a result, more and more people are paying attention to this mental and psychological illness. But as a family member who loves children, I really want to know the cause of autism in children. So what is the cause of autism in children?

Childhood autism is a developmental disorder characterized by severe loneliness, lack of emotional response, language development disorders, stereotyped repetitive movements, etc. In this society where the incidence of autism is extremely high, we all want to know the causes of autism in children. Let us learn about it together!

Causes of autism in children

Autism in children is a serious psychological disorder in children. The onset of autism in children may be related to factors such as genetics, family characteristics, social psychology, physiological anatomy, and biochemistry.

(1) Studies on genetic factors have found that the disease concordance rate among monozygotic twins is higher than that among dizygotic twins. The concordance rate for autism in monozygotic twins is 82%, and in dizygotic twins it is 10%. There are more autistic children in their families than in ordinary families. Autistic siblings and parents have similar cognitive deficits and specific personality traits, all of which indicate that there is a genetic basis for the onset of autism.

(2) Biological factors: The number of children with a history of perinatal damage is higher than that of normal babies, including congenital rubella, cytomegalovirus infection, premature birth, dystocia, birth trauma, asphyxia, etc. Children with autism are more likely to suffer from epilepsy (10%-15%), and their electroencephalograms are often abnormal. The study found that the left temporal lobe corner of the children was more likely to be enlarged, suggesting that there may be lesions in the temporal lobe of the brain.

(3) Biochemical factors: Dopamine and 5-hydroxytryptamine levels may be increased in children with autism, and adrenaline and norepinephrine levels may be increased in plasma, and neurotransmitters such as opioids may be abnormal, but these factors lack specificity. Brain tissue was found to show abnormalities in the migration of nerve cells in the cerebellum and a decrease in the number of Purkinje cells. Other studies have reported that autism may be related to the brain's limbic system, amygdala, and hippocampus. Other studies suggest that autism is related to rapid brain growth in the first year after birth.

(4) Family factors may be due to improper parenting methods or a special form of inheritance in the parents' personality, or both. The parents of the children are mostly highly educated, introverted, cold and stubborn towards their children, and the family lacks warmth. It has nothing to do with the parenting style of parents. The so-called indifference and formality of parenting shown by some parents of autistic children actually indicate that the parents may have mild similar disorders.

Through the above understanding, we know the causes of autism in children, and I believe everyone also realizes the terribleness of autism in children. I hope people can fully understand it, so that our children can have more happiness and innocence, and receive more care and help, so that they no longer feel lonely. So take action now!
