Recent publications now want to investigate the cause of autism based on studies with about two million children.
Danish and California researchers are confident that a study of more than 650,000 children has found no link between vaccination and autism development. But what benefits from the emergence of Open Spectrum Autism (ASD), which is involved in the development of social interaction and communication? Another study – the largest of its kind – wants to find an answer.

Her study, which she published in the journal "Jamaican psychiatry"They also come up with other risk factors – but they didn't have as much effect as genes, so environmental factors, which are usually poorly affected, are responsible for about 20 percent of the risk of autism. However, in most cases, a combination of several factors. leads to autism spectrum disorder.
"Although families are often concerned about environmental risk factors related to autism, the reality is that genetic factors play a much bigger role overall," study leaders summarize. The weight of the mother, cesarean section or metabolic disorders according to the study has no or very little influence on the development of autism.
