I absolutely welcome more research into autism, its prevalence, genetics, and potential causes. What I don’t welcome is the mainstream media spreading misinformation.
Changes in the DSM diagnostic criteria over the years has significantly influenced how autism is understood and diagnosed. Each edition of the DSM has shifted the framework, altering what is considered necessary for a diagnosis. For example, earlier versions used terms such as Autistic Disorder, Asperger’s Disorder, and Pervasive Developmental Disorder – Not Otherwise Specified (PDD-NOS). With the release of the DSM-5, these were merged under the single umbrella term Autism Spectrum Disorder (ASD).
These changes have had a direct impact on who meets the criteria, how clinicians approach assessments, and the way services and supports are allocated. For some families, it has meant clearer pathways and recognition; for others, it has raised concerns about children who might previously have qualified for a diagnosis but now fall outside the updated thresholds.
And lastly-
Does anyone honestly believe that parents pursue an autism diagnosis for their child “for fun”? The diagnostic process is long, rigorous, and emotionally exhausting. Parents don’t enjoy spending countless hours in assessments, advocating for their child at every level, and rushing between therapy appointments. On top of that, they constantly face critique from those in the community who are far less informed.
For families, this is not a hobby or a convenience: it’s an ongoing fight to ensure their child gets the support, understanding, and opportunities they deserve.
