Symptoms

Autism

In most cases, the symptoms of autism are detectable using certain screening tools on children 18 months old. However, parents and experts in autism treatment usually become aware of the symptoms before this time. In general, a formal diagnosis of autism can be verified. The medical specialist will rule out other disorders and use tests specific to autism and decide where a formal diagnosis of autism, autism spectrum disorder, or another disorder is appropriate.

There are a number of things that parents, teachers, and others who care for children can look for to determine if a child needs to be evaluated for autism. The following symptoms may be signs of autism and indicate that a child should be evaluated for autism or related communication disorders.
