Very much so. What we now call Autism Spectrum Disorder was referred to as "childhood schizophrenia" in the DSM-2 [1], things only started moving in the right direction with the DSM-3 [2] when it was finally sort-of recognized as an independent disorder of "infantile autism", but some core elements of ASD like sensory processing differences were only recognized in the DSM-5.

There's a good overview at [3]. It's good that criteria are different today, the criteria from decades ago failed to include majority of ways that autism expresses itself, many of which benefit from support and accommodations even though they're not obviously debilitating.

And let’s not forget that until the DSM-V, a child could not be diagnosed with both autism and ADHD (see section E at the bottom of this table [0] showing changes from the DSM-IV to DSM-V):

> The symptoms do not occur exclusively during the course of a pervasive developmental disorder, schizophrenia, or other psychotic disorders and is not better accounted for by another mental disorder (e.g., mood disorder, anxiety disorder, dissociative disorder, or a personality disorder).

The DSM-V states that they can exist together. In fact something like 28-44% of people with Autism exhibit some form of ADHD. [1]

It just goes to show that we’re still evolving in how we understand things. And then we can get into things like twice exceptionality and Asperger’s…and yeah. Lots to learn.
