What is the cause of autism in children?

Autism in children can be affected by many factors, including genetic factors and family factors. Parents’ indifference to their children, children’s lack of family warmth, or some trauma may be the reasons.

1. Genetic factors: Some children are related to genetic factors. The role of genetic factors in autism has become clear. 2%-6% of the siblings of children with this disease suffer from this disease, and the concordance rate of monozygotic twins is as high as 36%.

2. Family factors: The parents are professional technicians, highly educated and relatively intelligent, but they are rigid in their work and have a tendency to coerce their children. They are cold and stubborn towards their children, and the family lacks warmth.

3. Organic brain damage: such as birth trauma, intrauterine asphyxia, infection, poisoning, etc. 15%-50% of children have epileptic seizures, abnormal EEG, and non-specific changes in brain CT and MRI. Some are accompanied by neurological signs, body deformities, etc. Congenital rubella virus infection and cytomegalovirus infection may be related to the onset of autism.

4. Environmental factors: Lack of rich and appropriate stimulation in the early living environment, and failure to teach social behavior. Or children who are in a monotonous environment for a long time will use repetitive actions to stimulate themselves and will not be interested in the external environment.
