Autism is a spectrum or range of conditions, and the exact cause is still under investigation. Research on causes suggests that a combination of factors, genetic and environmental, may explain differences in development.
Autism is not caused by the received education, nor its social circumstances, and is not the fault of the individual with the condition, nor their parents. Scientists do not know the exact causes of autism spectrum disorder (ASD).
Autism was first discussed in the 1940s, but very little was known about it until the past few decades. Even though there is a lot of research directed towards this, there are no conclusive results.
While there is currently no known single cause of autism, early diagnosis helps a person receive the support and services they need, which can help them have a quality life with many opportunities.
