Discovering Autism: Unraveling an epidemic

Alan Zarembo:

Amber Dias couldn’t be sure what was wrong with her little boy.
Chase was a bright, loving 2 1/2-year-old. But he didn’t talk much and rarely responded to his own name. He hated crowds and had a strange fascination with the underside of the family tractor.
Searching the Internet, Amber found stories about other children like Chase — on websites devoted to autism.
“He wasn’t the kid rocking in the corner, but it was just enough to scare me,” recalled Dias, who lives with her husband and three children on a dairy farm in the Central Valley town of Kingsburg.
She took Chase to a psychologist in Los Angeles, who said the boy indeed had autism and urged the family to seek immediate treatment.
