Simple checklist may spot signs of autism by age 1

MSNBC.com (April 29, 2011) - A simple checklist that parents fill out in the waiting room may help doctors someday screen for warning signs of autism as early as a baby's first birthday.

San Diego pediatricians tested the tool with more than 10,000 babies at their 1-year checkups, looking for such things as how the tots babble, gesture and interact with others.

The research, being published Thursday, is a first step in the quest for earlier autism screening. It's not ready for routine use, as more work is needed to verify its accuracy. But it also may prove valuable in finding more at-risk babies to study what causes the developmental disorder.

"There are subtle signs of autism at one year if you just look for them," said neuroscientist Karen Pierce of the University of California, San Diego, who led the study. "Let's just get these kids detected early and treated early."

Recent data suggest about 1 in 100 U.S. children has some form of autism, which ranges from mild to severe problems with behavior, communication and socialization. The American Academy of Pediatrics already urges autism screening during regular doctor visits at ages 18 months and 24 months. Yet a 2009 study found that on average, children aren't diagnosed until they're 5.

Experts say early therapy can lessen autism's severity, even if they don't know exactly what types will prove best. "The earlier you start, the better," said Dr. Lisa Gilotty of the National Institute of Mental Health, which helped fund the study.
