Increasing the previous federal estimate of 1 in 150, the new data suggest that 1% of children now exhibit some symptoms of an autism spectrum disorder (ASD), a collection of neurological conditions whose symptoms may range from mild social impairment to more serious communication, language and cognitive deficits. The estimate also represents a stunning 57% increase in prevalence since 2002, when health officials first began a nationwide effort to quantify the risk of autism in childhood.

...detailed report, published by the Centers for Disease Control and Prevention (CDC) on Friday, researchers combed through health and education records in 11 U.S. cities. In some sites, the rate of autism was as high as 12 cases per 1,000 children, but averaged across the country the final autism case rate was calculated at 9 per 1,000 children. That's compared to a national rate of 1 per 2,000 children prior to the 1980s, and 6 per 1,000 children as recently as the 1990s...
...clear how much of the rise reflects a true increase in ASD risk and how much is due simply to improved awareness and diagnosis of the disorders. Increased access to special education classes and other therapies may also be inflating the numbers, as educators and parents enroll more children in hopes of optimizing their learning environment. Indeed, CDC researchers found that among sites where they had access to both health and education records, the prevalence of ASD was higher on average than in sites where only health information was available...
...latest statistics underscore the looming public health problem that autism has become, and highlight the urgent need for research on causes and treatments, as well as better support services for families caring for autistic children. The CDC considers ASDs a significant public health concern, says Rice, and researchers across the country continue to discover new genes associated with the condition. But for advocates of families affected by autism, the efforts are still not enough. "We are really seeing exciting things happening, but the pace is too slow, it just doesn't measure up to the size of the crisis," says...
...largest manufacturers, eventually shelled out millions in damages to U.S. troops who were exposed to it while it was being used as a wartime defoliant from 1961 to 1971. The U.S. government still spends billions every year on disability payments to those who served in Vietnam - including their children, many of whom are suffering from dioxin-associated cancers and birth defects. In October, the Department of Veterans Affairs added leukemia, Parkinson's and a rare heart disease to the list of health problems associated with Agent Orange. Yet U.S. official policy maintains that there is no conclusive evidence that...
