Can a person have Asperger's and DID?

I know at least one person who have both diagnosis (not label, they went through the whole diagnosis process for both condition). I've heard of other people who also have both, but as I don't know them personally, I don't know if both are formal diagnosis or labels put by their psych.

I'm currently going through a full examination for both too, and I know other people who have one diagnosis and one "label/recognition by a specialist", and what stands out the most is : usually, there's one which masks the other. That's why nobody noticed anything.

First thing to consider is, even if there are more specialists for autism than dissociation, autism is also a very unknown condition. Even professional usually have a very stereotypical idea of what autism looks like. I talked about autism with my psych, she admitted she doesn't know anything about it and will not be able to help me on that topic. A lot of psychs specialized in dissociation are the same.

And from what I've heard, people specialized in autism often don't know how to recognize complex dissociation, some even consider dissociation as a symptom of autism, like others consider dissociation as a symptom of psychosis.

Also, for the ones who have only few specifics symptoms of autism and/or can mask it, the dissociation helps masking even more efficiently.

You can also add cultural variations and creations... For example, being gifted is a semi-official diagnosis given by trained psychologists in my country (and some country around mine), we call that "haut potentiel intellectuel" [high intellectual potential]. It's basically made when a child has strong intellectual + school-related skills and specific interests without displaying enough of "bad" symptoms (like stereotypical behaviors, being obviously heavily socially impaired, having huge meltdown, having huge issue with staying focused, having a lot of motor skills issues, etc.) to justify going through an autism/ADHD diagnosis.

It was a big trend when I was young. For many parents, the "gifted" label was less scary than "autism/ADHD", and now, among my generation, there are "gifted" people who face a lot of issues because they were in fact autistic/ADHD children really good at masking, but they are exhausted and can't handle it anymore. And being diagnosed as an adult is really hard, it can take years to have your first appointment, so they struggle to have access to some help.

There are also a lot of children with autism/ADHD+dissociation, or autism/ADHD+CPTSD who received this "diagnosis" and basically saw their needs and/or abuses being ignored. It wouldn't surprise me if some ended up having DID/OSDD.

For the ones who are very impaired by their autistic symptoms and get that diagnosis first, people around them can put everything unusual under the "autism" diagnosis, without even asking themselves if it's coherent or not.

Now both condition are more known, professional starts talking about cases where they encountered both autism/ADHD and complex dissociation, but it's something really new.

On a more scientific level, there's people who just started to study autism and how it can lead to higher risks of developing PTSD, CPTSD and dissociative disorders. The director of the CTAD clinic (Complex Trauma And Dissociation clinic) have made two videos about it : one as an introduction about the link between autism and dissociation, the second is an interview of a researcher working on that topic (there's also a lot of interesting studies in description). You can find them on their Youtube channel.
