Exams and Tests

The American Academy of Pediatrics (AAP) recommends screening children for autism during regularly scheduled well-child visits. This policy helps doctors identify signs of autism early in its course. Early diagnosis and treatment can help the child reach his or her full potential.

When a developmental delay is recognized in a child, further testing can help a doctor find out whether the problem is related to autism, another pervasive developmental disorder (PDD), or a condition with similar symptoms, such as language delays or avoidant personality disorder. If your primary care provider does not have specific training or experience in developmental problems, he or she may refer your child to a specialist-usually a developmental pediatrician, psychiatrist, speech therapist, or child psychiatrist-for the additional testing.
