The DSM-5 now organizes disorders by age of onset, differentiates those such as ASD that impact brain development from those impeding other domains, and indicates how disorders may change across the lifespan. As such, your child's past and present symptoms will be taken into account during diagnosis (Clay, 2013). During the evaluation process for ASD, clinicians and diagnosticians will also take note of an your child's genetic and medical history (including conditions such as anxiety, depression, seizures, or gastrointestinal issues) and his or her language and intellectual functioning (Autism Speaks, 2013). 

 

Presence of a language delay in early childhood is now no longer required for a diagnosis of autism spectrum disorder (ASD). Instead, Social (Pragmatic) Communication Disorder, or SCD, has been added to the DSM-5. The disorder involves language deficits particular to social situations or interactions. While SCD does not include restricted interests or repetitive behaviors, and therefore does not fall under the ASD umbrella, individuals who previously would have been diagnosed with PPD-NOS or Asperger's Syndrome may now be identified more accurately with SCD.
