New Center for the Control and Prevention of Disease in Autistic Spectrum Disorder (ASD) , released on Thursday, there is little good story he offers. It estimates that around 59 children across the country have a complex development disorder, a figure that has remained unchanged from its previous estimate a year ago. However, for a variety of reasons, this is likely to be a low level of appreciation.
Autistic spectrum disorder is a complex condition, one of which is contributing to a number of reasons. Genes are likely to play a role, as will environmental factors such as air pollution or older parents. The symptoms are also complex, but generally include problems with communication, sensitivity to contact and other sensory inputs, and digestive issues.
For over ten years, the CDC has considered the autism rate in children through its Autism and Developmental Disability Monitoring. network, or ADDM. The ADDM compiles special health and education records from children living in different states to estimate. Traditionally, this estimate ̵
“The 4-year estimate is definitely a temporary estimate, and is expected to be more when you survey children at an older age,” said author Walter Zahorodny, associate professor of pediatrician by Rutgers, with Gizmodo. “But the advantage of studying younger children is that the trend [of autism rates] is changing or not.”
report together on nearly 200,000 4-year-old children from seven states in the years 2010, 2012, and 2014. Only three states – New Jersey, Missouri, and Arizona – had data for all years, however. As with other estimates, it found that the overall prevalence of autism has increased from 13.4 per 1,000 children in 2010 to 17.4 per 1,000 in 2014. This equates to approximately one in 59 children.
“ We are not really any ideas the reason why this increase has occurred, and what the risk factors and drivers for this increase are. And equally importantly, we have not made any progress in improving early detection. ”
It is a matter of trying to find out how common autism is common. Doctors, parents and schools generally looked better at ASD. But according to Zahorodny, autism has also increased dramatically.
“We have been monitoring for about 20 years, and this increase is clearly not better,” he said, referring to research showing that 80 per cent of the increase can be increased. link to external factors such as the environment. And while the new report was the same in 59 as the earlier CDC estimate, it is likely that, as these children grow older, more people will be diagnosed with autism.
“These results show that we will not yet see a point where the autism rate is hit. It is growing, and when we look at the same group four years from now on, it is likely that we will see what [this rate] was too small, too, ”said Zahorodny.
There is also the possibility that the current national estimate may now be absent. Looking at the states alone, New Jersey was the only person who showed an increase in the autism rate during 2014, one in 35 children. But there are several reasons to think that the rate in New Jersey is the best barometer of autism prevalence, according to Zahorodny.
“The quality of information we have in New Jersey is very good, and that is the information that I like surveillance studies with this need,” he said. “The resources to really identify these children are here.”
New Jersey has a fairly large and diverse population, for example. The public education system may be better able to connect children and parents with special education services than those in other states (the state has a number of different organizations in place near the top of education). And it is in the New York City area, where families have access to plenty of doctors and specialists.
The other way in which we talk about the autism rate in the coming years is how it is diagnosed now. Previously, clinicians were relying on the fourth edition of the Mental and Diagnostic Diagnostic Handbook, or DSM, to diagnose a case of autism. However, the DSM-V reviewed its ASD criteria. This included the removal of the label on Asperger disorder, which was considered to be closer as autism, and to create a new diagnosis – social communication disorder – often applied to people with asperger symptoms.
When Zahorodny and his co-author used the two sets of criteria from DSM-IV and DSM-V in the 2014 group of children, for example, they found that about 20 per cent fewer children were considered to have ASD. DSM-V. So scientists (and journalists) will have to find a way to account for these differences and make a correct representation of the picture of ASD and similar disorders in America.
“These people don't seem to go out when we start categorizing them in a different way,” Zahorodny said. “But it is possible – and very desirable – to maintain a consistent approach to the way we define autism.”
Of course, the current estimates from the CDC are somewhat dated, since they are only so late with 2014 But Zahorodny says that the CDC in the middle of tracking the prevalence of autism among children aged 4 to 8 years of age with data later, and its own team is already working by riping part of that data . (Research on other places continued to increase rates of autism with other more up-to-date data sources). The ADDM will also begin studying how 16 year old children are dealing with ASD, including whether any behavioral interventions have helped.
Meanwhile, we are still struggling to help young children with ASD. We know, for example, that the earliest ASD is diagnosed in a person, the more effective interventions such as communication therapy can be. However, the average age of diagnosis, about 4.5 years, has not changed in recent years, according to CDC data. There are delays in the genetic and environmental causes of autism (not including vaccines), and how we can prevent them.
“We have no real idea of why this increase has occurred, and what the risk factors and drivers for this increase are. And equally importantly, we have not made any progress in improving early detection, ”said Zahorodny. “So, please do everything we can to improve the early screening of autism – preferably at 18 to 24 months – and we will continue to watch and understand the factors behind the rise of autism. ”
