Autistic Kids Siblings

Autistic Kids Siblings, While less than one percent of the general population born today will be diagnosed with autism spectrum disorder (ASD), a new study found that statistic jumps to 18.7 in children with an autistic sibling: They have almost one in five chance of being diagnosed with the disorder.
The results confirmed the suspicions of experts that previous estimates of risk – that put the brother of an autistic child risk of being diagnosed three to ten percent – were lower than the real ones.
“Those of us who work in the field knew the rate was much higher than the rate previously published, but I do not expect it to be so high,” said senior study author Sally Ozonoff, professor and vice chair of research in the department of psychiatry and behavioral sciences at the University of California Davis MIND Institute Medical Center.
The study, which is believed to be the largest of its kind to date, conducted by Research Consortum baby brothers, a large-scale network of researchers from several universities in the U.S., and was published in the August 15 online edition of the journal Pediatrics.
According to the study results “were child gender and the presence of> 1 older sibling affected the results significant predictors of ASD.” Men are three times the risk of developing the disease than women, and double the risk increases if an older sibling with ASD.
Although the findings likely to be considered by parents of autistic children who are concerned about the additional risks for children, the study’s conclusions “that any family that their particular risk is 18.7 percent. That’s an average “Ozonoff said. “Some families will likely have almost zero risk, and some have a much higher risk. We’re not at the point where you can go to a genetic counselor, to have blood drawn and look for certain genes that increase the risk of an individual family. ”
However, those who are most at risk can monitor the siblings of children with ASD and be alert for signs of the disease at an early stage, when treatment is most effective.
Autism is a spectrum disorder usually manifests itself enigmatic with the first three years of life. It mainly affects social and communication skills. The disease varies in severity, and some children are able to thrive despite the disorder, while others remain largely unresponsive to treatment.
Government statistics suggest that the prevalence of autism is increasing 10-17 percent annually. There is no known cause or cure for autism.
