Why are Autism Rates increasing ?
It's true that the number of autism diagnoses has increased- from 115,400 people in 2012 to 164,000 in 2015 (ABS).
But... The simple fact is, there's actually no evidence that the incidence of autism is increasing at all. We're probably just better at spotting it.
In the past , often people who had autism were thought to be introverted or shy and were never diagnosed.
These days, we are able to spot autism much more easily and earlier.
We also now know that it's a spectrum. So other disorders which used to be diagnosed separately ,now come under the autism spectrum disorder umbrella. This makes it look like there has been a more dramatic increase, but there hasn't been.
It's important to note that the rising autism rates over time may not necessarily mean that more people have autism. Instead, the observed increase may be a result of improved screening effort and more public education about Autsim.
This has led to greater awareness and understanding of autism, resulting in increased efforts to identify individual who may have previously gone u diagnosed. The expansion of diagnostic criteria and better access to healthcare and evaluation services have also contributed to the higher reported rates.
As for why autism rates increasing, it's possible to view the increasing rates as an indication of a greater awareness and understanding of autism rather than a higher prevalence of the condition.
Why Is Autism More Common Now?
If autism prevalence hasn't increased,then why is autism more common now than 50 years ago? Why is autism increasing in multiple population?
The prevalence of autism has appeared to increase over time for several reasons. As autism becomes more well known, there is more awareness of early signs of the disorder, which leads to more parents asking for screening and more identification of autism spectrum.
Changing health factors, like increasing survival rates for preterm babies and new environmental threats may be contributory.
Some reasons why the increase in autism is becoming apparent :
Broadened Criteria for Diagnosis:
The broadening of diagnostic criteria for Autism spectrum disorder has Played a significant role in increased prevalence of autism. Over time, the diagnostic criteria have expanded to encompass a broader range of behaviours and symptoms associated with ASD. This expansion has enabled healthcare professionals to identify and diagnose individuals who may not have met the previous diagnostic criteria. By including a wider spectrum of individuals, the broadened criteria have contributed to the higher rates of autism diagnosis.
Increased screening:
The increased availability and utilization of screenings have also contributed to the higher rates of autism diagnosis. Healthcare providers, educators, and parents have become more aware of the early signs and symptoms of autism, leading to improved screening efforts. Screening tools and assessment method have also improved, allowing for more accurate identification of autism in children at an earlier age. Increased screening have helped in identifying individuals who may have gone u diagnosed in the past, leading to a rise in autism diagnoses.
Increased Awareness :
Increased awareness and understanding of autism have played a crucial role in the increase in autism rates. Through efforts in public education, media representation, and advocacy, awareness about autism has significantly expanded. This heightened awareness has led to increased recognition of autism -related behaviours and symptoms, prompting parents to seek evaluation and diagnosed, or rule it out . By improving awareness, more individuals with autism are identified and receive the necessary support and intervention at earlier ages.
Environmental and other factors:
While the exact causes after autism are not fully understood, environmental factors has been studied as potential contributors to the rise in autism rates. Viral in
