More than 10 percent of preschool-age children diagnosed with autism saw some improvement in their symptoms by age 6 and 20 percent of the children made some gains in everyday functioning, a new study found. Canadian researchers followed 421 children from diagnosis (between ages 2 and 4) until age 6, collecting information at four points in time to see how their symptoms and their ability to adapt to daily life fared. "Between 11 and 20 percent did remarkably well," said study leader Dr. Peter Szatmari, chief of the Child and Youth Mental Health Collaborative at the Centre for Addiction and Mental Health in Toronto. However, improvement in symptom severity wasn't necessarily tied to gains in everyday functioning, Szatmari said. Eleven percent of the children experienced some improvement in symptoms. About 20 percent improved in what experts call "adaptive functioning" -- meaning how they function in daily life. These weren't necessarily the same children, he said. "You can have a child over time who learns to talk, socialize and interact, but still has symptoms like flapping, rocking and repetitive speech," Szatmari said. "Or you can have kids who aren't able to talk and interact, but their symptoms like flapping reduce remarkably over time." The interplay between these two areas -- symptom severity and ability to function -- is a mystery, and should be the topic of more research, Szatmari said. One take-home point of the research, Szatmari said, is that there's a need to address both symptoms and everyday functioning in children with autism spectrum disorder. "If it were my kid, I would want adaptive functioning to improve and [feel] symptoms are less important," he said. "Adaptive functioning determines your place in the world."
