This pressing question is difficult to address, but the answer may derive from how we define communication. The process begins with looking at the diagnostic criteria for each condition. The DSM IV introduced the Asperger syndrome as a diagnosis in , making it the newest of the five pervasive developmental disorders. There are five developmental disorders in the pervasive developmental disorder classification, also referred to as the autism spectrum.
Each of the disorders must have some things in common in order for them to fit into the spectrum, but each subset of the autism spectrum meets specific criteria for proper classification. This approach to organizing the conditions helps to create appropriate treatment plans for individual cases. A diagnosis of PDD-NOS indicates that the individual has many of the signs of autism while not meeting the criteria of Retts, childhood disintegrative disorder, classical autism, or Aspergers.
The symptoms are pronounced enough to interfere with the person's ability to function normally on a daily basis. Many PDD-NOS cases are very high functioning, but some are low functioning, especially if the individual has a dual diagnosis. Just as the autism spectrum covers a wide range of abilities, so does the cases of PDD, not otherwise specified. Some assert that the diagnosis should be replaced with high functioning autism , but this works on the assumption that all individuals with the diagnosis are high functioning though this is not always the case when there is a comorbid condition.
In addition, some assert that Aspergers is high functioning autism , but it is a distinct condition that does not meet the same criteria as classical autism in spite of its similarities. The question may be addressed by looking at the factors that make Aspergers unique from the other pervasive developmental disorders, according to the DSM IV.
Two areas that make Aspergers unique among the five pervasive developmental disorders are communication and cognition. Individuals diagnosed with Aspergers syndrome do not display the marked delay in language acquisition. Autism 3. Asperger syndrome 4. Rett syndrome 5. Others use the general category label of PDD because they are hesitant to diagnose very young kids with a specific type of PDD e.
Both approaches contribute to confusion about the term, because the term PDD actually refers to a category of disorders and is not a diagnostic label.
There are several justifications for this. Very young kids have limited social interaction and communication skills to begin with, thus it can be tricky to diagnose milder cases of Autism in a toddler. The unspoken assumption is that by the age of 5, unusual behaviors will either resolve or develop into diagnosable Autism.
Because of the "NOS" i. Others have near full-blown Autism, but without some of its symptoms. To confirm the diagnosis, continue to consult with your doctor and get a referral to either a neurologist or child and adolescent psychiatrist to figure out exactly what is going on with your child. Once you have a definitive answer, you can then check for resources in your local area.

You may be familiar with autism and its different types and spectrums, but you may not know how those types differ. These two types are the more mild forms of autism, so we will be taking an in-depth look at both to help you better understand them and their differences.
Children and adults with this form of autism typically have difficulties with social interactions and understanding social norms.
