Parents of minority children with autism are more likely to report that their children have poor quality of care than are parents of minority children with other developmental disabilities.
With every passing year, men are increasingly likely to transmit new mutations to their children, according to the largest study yet of the so-called paternal age effect, published yesterday in Nature. The findings could help explain why older men are more likely to have a child with autism or schizophrenia than are younger men, the researchers say.
Studies of autism prevalence should screen a representative sample of all individuals in the population, even those with no indications of the disorder, says epidemiologist Young-Shin Kim.
Child psychiatrist and epidemiologist Eric Fombonne digs through the latest report on the prevalence of autism, suggesting reasons for the apparent increase in the disorder’s rates.
Full siblings are twice as likely as half siblings to share a diagnosis of autism, according to a short report published 28 February in Molecular Psychiatry. The results suggest that genetic factors play an important role in the risk of developing autism, the researchers say.
Foreign-language translations of autism screening and diagnostic instruments are proliferating, but there is little research evaluating how well they work. Validation is necessary not only to ensure that children who have autism get the services they need, but also to accurately measure the disorder’s prevalence in different countries, researchers say.
The likelihood of being diagnosed with autism has increased for children born each year since 1992, especially for individuals at the higher-functioning end of the autism spectrum, reports a study published 7 December in The International Journal of Epidemiology.
