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.
