From what I've been told over the years by various different head people, the overlap between the outward symptoms of cptsd and autism is somewhat large.
The underlying causes are usually very different, but the expression has enough overlap that they always check for cptsd markers and questions.
In my anecdotal experience, of course.
It's also entirely possible to have both, which makes it even more complex.
