Recent publications now want to investigate the cause of autism by studying about two million children.
Danish and California researchers are convinced that a study of more than 650,000 children found no link between vaccination and the development of autism. But what benefits does the occurrence of Autism Spectrum Disorder (ASD) interfere with the development of social interaction and communication? The second study – the largest of its kind – wants to find the answer.
This factor basically determines whether a person develops autism
An international research team estimated the data of two million children and came to a clear conclusion: 81 percent of ASA risks are related to genetic predisposition.
Her research she published in "Pit Psychiatry"They also shed light on other risk factors – but they didn't have as much impact as genes, so environmental factors, which are usually badly affected, represent about 20 percent of autism risk. However, in most cases, a combination of multiple factors leads to a disruption of the autism spectrum.
"Although families are often most concerned about the environmental risk factors associated with autism, the reality is that genetic factors play a much larger role overall," study leaders conclude. Maternal weight, cesarean delivery or metabolic disorders according to the study, they have little or no impact on the development of autism.

Mostly genetic: 22,000 children developed autism
For their findings, researchers analyzed the medical records of over two million children from Denmark, Finland, Sweden, Israel and Western Australia, born between 1998 and 2011. 22,000 of them developed autism by the age of 16, The latest study provides the strongest evidence that genetic causes are crucial.
