Selective Mutism is not Equivalent to Autism
Lately I’ve been seeing a lot of people who think that selective mutism is a symptom of autism. This is not true. Selective mutism is classified as an anxiety disorder and is it’s own separate mental illness. It is not even on the autism spectrum.
Furthermore, the current DSM-V criteria makes it very difficult if not impossible for an individual to be diagnosed with SM and autism at the same time as it states that the disorder is “not better explained by a communication disorder and does not occur exclusively during the course of autism spectrum disorder, schizophrenia, or another psychotic disorder.”
But the main difference is that people on the autism spectrum will have a speech disorder that will limit language ability and render them non-verbal whereas individuals with selective mutism will usually have no disorder other than anxiety that prevents speech. People with SM will also usually show increased empathy, relate to other people easily, and show appropriate social skills where some people who have autism may not.
I’m not trying to put down people on the autism spectrum. I am simply trying to prevent the spread of misinformation.
