Firstly it's important to point out that it is diagnosis rates that are rising, not cases of Autism - there is no evidence to support the idea that there are more cases of Autism.

Autism wasn't considered a diagnosis until 1980 when it was first listed as a diagnosis in the DSM-III under pervasive developmental disorders, in the 1987 revision of the DSM-III-R the diagnostic criteria were expanded and they also included PDD-NOS - both of these changes would have allowed more people to be diagnosed as Autistic.

In the 1994 edition of DSM-IV they included the diagnosis of Asperger Syndrome which was regarded [falsely] as a milder form of Autism - really the only difference between AS and ASD is that in AS there are no developmental delays, thus why the most modern edition of the DSM has removed the diagnosis. As AS allowed those who were not severely effected to be diagnosed as Autistic it opened up diagnosis to a significantly larger group of people. A typo in the DSM-IV also meant that a wider group of people could be diagnosed as Autistic because it allowed people with developmental problems or (instead of and) communication problems to be diagnosed.

So basically Autism became a diagnosis in 1980, and in 1994 the addition of a wider understanding of Autism increased Autism diagnosis - all these people are Autistic, it just made diagnosis easier.

There's absolutely no evidence to suggest that autism has ever started to increase. We have higher rates of diagnosis because of increased awareness and changes to diagnostic criteria, this doesn't mean autism is increasing.

Who is the youngest person with autism?

Autism has a genetic component, so people can be born with it. Others are born with a susceptibility to autism that is probably triggered by an environmental factor. So, there are newborns with autism. Usually, autism is not diagnosed until age 2 or 3, but some cases are diagnosed earlier, and some are not identified until much later.


How did my child develop autism?

Research suggests that the development of autism is rooted in very early brain development. However, in most cases, no one cause can be identified. Research has identified several genes that can cause autism in and of themselves. These account for about 15 percent of cases of autism spectrum disorders. Research has identified more than 100 genes or gene changes (mutations) that increase the risk that a child will develop autism. In most cases, genetics alone can't distinguish why one person has autism and another does not. Those most associated with increased autism risk include advanced parental age at time of conception and prematurity with very low birth weight. Other possible environmental risk factors include maternal diabetes or infection during pregnancy and certain birth complications, particularly those that may involve oxygen deprivation to a baby's brain.


Was autism called something else before it was identified as autism?

Before autism was known as is, the oldest record of it was known as somebody who had been possessed by evil. There were false rumors about it being a threat to society and convinced everyone that it must be vanquished. No witch that was burnt had lived to tell of their lives.


Why is autism so prevalent today?

There's nothing to suggest that autism is more prevalent today than it was decades, hundreds, or thousands of years ago. Autism diagnosis is on the increase but this doesn't mean that autism is on the increase.


Does Atticus Shaffer have Asperger's Syndrome or autism?

The actor Atticus Shaffer is not described as having autism or Asperger's Syndrome (AS), and details about him do not make it seem likely. The character he plays on the television series The Middle, Brick, is "quirky" and has symptoms that make it seem possible that the character has an autism spectrum disorder, but the character is not identified as having one on the show.


Where did kids that had autism go in 1935?

Autism wasn't identified until the late 1960's and even now the definition and research on it changes continually. Special needs children were not identified in 1935 and many who were severely impaired with various conditions were put into mental wards, hospitals for the insane, or were at home with the parents. It is only in recent history that special needs children were given access to programs that meet their needs.


Can you be diagnosed with autism in the 1960s and later be rediagnosed with Asperger's Syndrome instead?

Absolutely. Asperger's Syndrome had not been identified as a condition then, so children with it were diagnosed with other conditions including autism or obsessive-compulsive disorder or were described as odd, troublemakers, or whatever characteristics were most dominant.

What is adult autism?

Basicly, autism is something you are born to have, not something that you could grow into. So, adult autism, means that a child with autism grows up and become an adult with autism. However, if you didn't find out that you have autism until you are an adult, then your autism must be the mild kind on the entire autism spectrum.
