MONDAY, April 2 (HealthDay News) -- About 10 percent of children with autism experience rapid gains in skills -- progressing from severely affected to high functioning -- but with less-educated mothers are much less likely than richer white kids to fall into this group, a new study suggests.
Analyzing nearly 7,000, researchers from Columbia University in New York City also found that these kids typically display six typical patterns of social, communication and and that those whose symptoms were least severe at diagnosis tend to improve more quickly than others.
"These children follow really different pathways over time, changing at very different paces and according to very different patterns," said study author Christine Fountain, a postdoctoral researcher at Columbia's Institute for Social and Economic Research and Policy. "Most children do get better, at least a little bit. But we found it somewhat surprising that about 10 percent improve really rapidly and to a great extent."
