What causes autism?
There is no single reason why people develop autism. However, research shows that genetics constitute the main cause. Here, many genes are involved, meaning that there is not one single gene that causes autism.
Research has also shown that some close relatives of people with autism have what is called ‘the broad phenotype’. This means that they have more traits from autism than the rest of the population without meeting the criteria for autism.
Environment is also of importance
The prevailing theory is that the different development begins in the embryonic stage. This includes changes in connections between central areas of the brain.
Genetics alone cannot explain the changes in the brain. Likewise, genetics cannot explain the wide variations within the autism spectrum.
External circumstances are therefore also important, for example premature birth and certain impacts on the unborn child increase the risk. These impacts may, for example, be infections or toxic substances.
In the vast majority of cases of autism, the exact cause is not known. Regardless of the cause, however, it is a congenital condition. It gives rise to a different development of the brain.
