Some examples of topics that are being investigated include:Д¬urrently, the risk factors for ASD can include: ASD is often described as genetically heterogeneous (meaning it may have many causes).ДЄdditionally ASD may be associated with certain genetic disorders such as fragile X syndrome or Rett syndrome.ДЄs with possible genetic causes, researchers are continuing to investigate potential environmental causes and other risk factors for ASD. Genetically speaking, mutations may be a contributing factor, but science is currently inconclusive on this.

ItвЂ™s generally agreed that a combination of genetic and environmental factors likely play a role in causing the condition. What are the risk factors for PDD-NOS or autism?ДЄSD is a very complex condition, and not all of the causes are known.

deficits in communication and interaction.

Since 2013, the symptoms of ASD now fall into two categories, which include: In the DSM-5, symptoms of PDD-NOS and other autism categories were consolidated.

problems using and understanding language.

Symptoms of a pervasive developmental disorder included: Previously, people were diagnosed with PDD-NOS when they didnвЂ™t display symptoms consistent other conditions under the вЂњpervasive developmental disorderвЂќ category. Read on to learn more about what PDD-NOS was, what the current diagnostic criteria says, and how the condition is diagnosed and treated today. Instead, these disorders were placed under the autism spectrum disorder diagnosis in the вЂњneurodevelopmental disordersвЂќ category. With this change, the entire category of вЂњpervasive developmental disordersвЂќ was eliminated, and the diagnosis of PDD-NOS was no longer used. In 2013, the American Psychiatric Association updated the DSM to its fifth edition.

PDD-NOS also included the diagnosis of atypical autism, which was used when an individualвЂ™s symptoms didnвЂ™t meet the full criteria for an autistic disorder diagnosis, either because the symptoms appeared or were diagnosed at an older age, they werenвЂ™t the typical symptoms of autism, or both.

PDD-NOS only applied to people who didnвЂ™t have any of the following diagnoses:
