CLEVELAND, Ohio— Though most children are diagnosed by age 4, many researchers feel the earliest signs of autism can be detected in babies as young as six to 18 months old. Early intervention and identifying the signs early leads to better outcomes.
Because it can be difficult, especially for parents to identify the earliest signs of autism, the Kennedy Krieger Institute and other research groups have produced simple online videos comparing the behaviors of children with suspected autism to those of typically developing infants and toddlers.
Autism has shown a dramatic increase in the past decade in the United States. According to the Centers for Disease Control and Prevention, currently autism affects one in 88 children.
In a current long-term study of babies from birth to age 3 differences shown in eye contact as early as the second month of life when the babies watched videos showing actresses as caregivers. A study conducted by Emory University in Atlanta, researchers identified declines in eye contact beginning as early as between 2 and 6 months of age in children who later developed autism.
Pediatric neurologist and autism specialist Dr. Max Wiznitzer from the University Hospitals Rainbow Babies & Children’s Hospital, said earlier work by the same group of Emory researchers also showed that children with autism spend more time focusing elsewhere, often on the mouth and less time focusing on the eyes when someone is speaking.
Impaired social behavior and lack of eye contact is a trademark characteristic of autism spectrum disorders (ASD). Other symptoms can be difficult to spot, especially at a young age and vary widely.
Dr. Rebecca Landa of the Kennedy Krieger Institute helps explain in the institute’s 9-minute tutorial video some of the ASD behavioral signs in one-year-olds in six video clips comparing toddlers who show no signs of the disorder to those who show early signs of autism.
Though Wiznitzer indicates that parents should be cautious and not drawing any conclusions about their children from video alone, he states the video is particularly helpful because it lays out the behaviors to watch out for before each video clip. In typically developing children, these include sharing enjoyment by smiling at others while playing, sharing a toy with a parent or other adult, and imitating the motions of others while playing. Behaviors that are related to autism include an unusually strong interest in a toy or object, no engagement with other people during play, and no response to hearing his or her name.
“[The videos] can show you some of the early features of autism, but some of these behaviors can be seen in other developmental disorders, so if you have any concerns it’s important to have an expert evaluate your child,” he said.
