How are autistic children formed?

summary

We are generally not unfamiliar with autism. Autism will have a great impact on children's growth. Autistic patients will not speak and don't like to socialize. Even when children grow up, they won't be treated. Autism is very difficult to cure. It is generally alleviated by themselves. There are many factors that cause autism, Some parents think that children suffering from autism are caused by their own neglect of their children. In fact, how can autistic children be formed otherwise.

How are autistic children formed?

Genetic factors: studies have shown that genetic factors are prone to the quality of the disease. The concordance of autism was more than 90% in monozygotic twins and 24% in dizygotic twins. The siblings of children with autism are 3-4 times more likely to suffer from autism than normal people, suggesting that the disease is related to genetic factors, but the specific mode of inheritance is still unknown.

Brain organic factors: perinatal damage history, abnormal EEG, soft sign of nervous system and epileptic seizure were more common in children with this disease. CT scan of brain in a few cases indicated ventricular enlargement; MRI examination showed that some of the children had cerebellar vermis hypoplasia, so it was considered that the disease was related to dysfunction caused by central nervous system abnormalities.

Neurobiochemical factors: Children's behavior is closely related to neurotransmitters. It is suggested that the activity of serotonin and / or dopamine in the central nervous system is decreased. Accompanied by hypothalamic dysfunction can produce autism. It is also believed that the symptoms of loneliness and inability to establish feelings with others are caused by abnormal neurotransmitters of endorphins.

matters needing attention

Many studies have shown that autism often coexists with some diseases, such as fragile X syndrome, tuberous sclerosis, muscular dystrophy, congenital rubella, phenylketonuria and xanthin metabolism disease, so it is considered that autism is a neurological syndrome with multiple causes. It can be seen that many scholars explore the causes of autism from different perspectives, and a few of them have achieved some biological basis. However, the nature of the causes of autism is still unclear and needs to be clarified.
