Autism is not a single disorder but rather a range of conditions, and therapy targeted to the specific subtypes of autism may be helpful for people with autism.
People with autism may have a wide range of symptoms. The author believes that autism symptoms may arise for different reasons in different people. Risks for autism may include genetic factors. Gene mutations have been found in about 10 to 20% of autism cases, but there are a variety of genes involved. Behavioral and cognitive therapies may work best when they are designed to meet the needs of the child. In the future, therapies that target specific genes may also be helpful.
