Can it be prevented? Can it be cured? What is the treatment?

At this point we do not know what causes Autism and so cannot fix (cure) what is wrong in the child's brain. Many therapies (medications, diets, etc.) are being tried but nothing is proven. Similarly, without knowing the cause of autism, there is no way to prevent it. At present, there is no cure for autism: there is no medication, no pills, no injections which can make the problem go away. The only consistently effective treatment for autism is a structured training program; therefore, a combination of a good school and parent training is the best known treatment. Autistic children can make significant progress if the intervention is appropriate and consistent. Early intervention, before the child is five, is especially crucial to the child’s progress. This is why an early and accurate diagnosis is so important. Autistic children grow to become autistic adults, and there is a particular need for meaningful outlets for social interaction and employment where possible
