hereditary factor
Autism is closely related to heredity. If there are autistic people in the family, children may inherit the sick genes from their parents.
environmental factor
Being lonely and monotonous for a long time may make it difficult for children to communicate with the outside world. Lack of verbal stimulation and interpersonal communication will reduce brain activity and lose interest in the outside world.
Family education
Some parents who have received higher education are too rigid and restrained in educating their children, which leads to their children not feeling the care of their parents and then unwilling to communicate with the outside world.
Immune system abnormality
When there is a problem with the immune system, the number of cells decreases and the resistance to the outside world decreases, people are more likely to suffer from autism.
Brain organ injury
Brain injury may desensitize the nervous system, leading to autism.
