Getting a Diagnosis

Early signs of autism can often be detected in infants as young as 6-18 months. For example, if a baby fixates on objects or does not respond to people, he or she may be exhibiting early signs of an autism spectrum disorder. Older babies and toddlers may fail to respond to their names, avoid eye contact, lack joint attention (sharing an experience of observing an object or event by gazing or pointing), or engage in repetitive movements such as rocking or arm flapping. They may play with toys in unusual ways, like lining them up or focusing on parts of toys rather than the whole. Parents who notice these signs, or are concerned their children are not meeting developmental milestones, should contact their pediatricians and request a developmental screening. The American Academy of Pediatrics recommends routine screening of all infants for autism as part of 18-month and 24-month well-baby examinations.  Learn more about the early warning signs of autism.

Early diagnosis and early intervention are critical. Studies show that about half of children with autism who are in an evidence-based early intervention program from age 3-5 can gain enough skills to be mainstreamed for kindergarten. There are now evidence based interventions for babies as young as 12 months old, and studies are underway to design treatments for 9 month old babies at risk for autism.
