Parents Should Look for Autism Signs Early

March 13, 2007 — -- A new effort is being launched to better educate parents and pediatricians about the earliest signs of autism.

There are no known causes or cures for this disorder, but the earlier a child is treated the better the prognosis.

Doctors at Maryland's Kennedy Krieger Institute, one of the country's leading autism centers, say they can now identify symptoms in children younger than ever before.

Children with autism withdraw into their own private worlds. Most children are not diagnosed until they are 3 to 5 years old, but the signs can appear as early as 6 months. The problem is those signs often go unnoticed or are ignored.

"Most people use the rule of thumb that if a child is showing developmental delays before the age of 3 that they'll catch up," said Rebecca Landa, a researcher at the Kennedy Krieger Institute. "But children with autism usually don't," Landa said.

Researchers at the institute are documenting in video just what symptoms to look for, even in an infant.

In one video, Landa points out how a baby does not look into his mother's face. "He's very unengaged with her," Landa said.

In about 30 percent of autism cases, researchers are now documenting what they call "regressive autism."

A child appears to develop perfectly normally for about a year, then something happens.

One boy documented by the Kennedy Krieger Institue is engaged and smiling at his mother at 6 months, with no signs of a problem.

When he reaches one year, he appears a little shy, but again, there is no reason for concern.

But at age 2, Landa says the signs in the boy are more obvious.

"Now you can really see autism in its full form. This child is not speaking. He's not paying attention to any social cue. He's totally fixated on the objects," she said.

Different children will develop autism at different ages. What's critical, say therapists, is to detect it when the first signs appear, because that's when treatments are most effective.

Chloe was diagnosed with autism when she was 2 years old. At the time, she could not speak or interact with the children around her, and she did not want to be touched.
