Overlap between autism and personality disorders

I have recently completed some online personality tests. They showed things like I have avoidant and obsessive personality disorders but when I read the description of those, I saw that those were the exact same things I have always struggled with because those are my autistic traits. I wonder if that's a false positive. Is it possible that I don't have these personality disorders but I got these results due to autism or do I have these personality disorders because I am autistic and ASD has affected my personality? I think this would be important to clarify for autistic people since treating personality disorders is not necessarily the same as "treating" autistic traits. Is it possible to change these at all?

  • my psychiatrist once answered this (sort of)... some people can have ASD and a personality disorder, sone are misdiagnosed one way or the other, the key difference is that autism affects people from birth and whilst some traits may develop/ change - essentially the issues faced have been life long, whereas personality disorders develop during life usually in response to a major event or trauma, particularly in the case of BPD/ EUPD. So the likelihood is that the similarities between ASD and personality disorders are the reason for your results rather than you having developed a personality disorder. Of course it’s possible you have both but more likely false positives being created by the ASD traits similarities to those of a PD.
