Recognizing Autism in Teens
Most children with autism are diagnosed somewhere between 3 and 5 years old, however, those who are higher functioning and did not have speech delays when younger, may not be diagnosed until much older, sometimes in their teen years when social interactions become more difficult and harder to navigate.
These children often show signs of what was previously considered Asperger's syndrome (this was previously a separate diagnosis but was integrated with autism spectrum disorders in the 2013 edition of the Diagnostic and Statistical Manual). Because symptoms were mild, parents may accept their child as "quirky" but not necessarily autistic.
During the teen years, when social skills and friendships become so important, the symptoms are more noticeable. As other teens are spending free time with friends and involved in many different activities, teens with ASD often spend time alone and are much more selective on what activities they join. During the teen years, especially if not diagnosed, they can develop depression or anxiety. They can seem distant or unable to express their emotions.

Teens with ASD may learn to compensate for some of their difficulties or differences, however, their difficulty with social situations and communication usually continue into the teen years. He or she may want to have friends but not know how to make friends or have problems initiating conversations or approaching other teens. Many are not concerned with outward appearance and don't worry about trendy clothing. They can find it exhausting trying to fit in with other teens. They usually are rule-oriented and feel uncomfortable when there are no rules to help them understand expectations.
If you recognize some of the symptoms of autism in your teen, talk with your doctor. A diagnosis isn't going to change your child or how you feel about your child but can help in accessing educational services, even as your teen goes to college. It can also help you better understand your teen and accept some of the differences you have noticed. Your teen may be relieved with a diagnosis, he may have wondered why he was different or why he had such a hard time making friends. A diagnosis may help him better accept who he is.
