Unfortunately, there is no way to prevent autism spectrum disorders (ASDs).
Experts are still seeking the definite cause or causes of ASD. There is also no known cure for ASDs. In both cases, there is a great deal of research going on in the hopes a breakthrough can be found.
But that does not mean nothing can be done. There are numerous treatments available that—while they cannot stop autism—can help people with ASDs work around the shortcomings of their condition and build on their strengths. Many people who have ASDs live well-rounded, fulfilling, and independent lives.
