I'm a parent. I won't get too involved as this space isn't entirely relevant to my situation and I understand it needs to be a space for partners.
I believe, and I have no evidence, but believe strongly that being an Autistic male dramatically increases the risk of having an ASPD. The 2 therefore co exist often and it isn't a case of misdiagnosis.
For me, as a mum, I felt for a long time,' this is autism ' which is present and eventually diagnosed, correctly I am sure. ( Significant genetic family history).
But over time, I now sadly feel, is there more here and is this actually also a problem of ASPD on top.
I now understand why even with the best intentions, an ASPD state may occur where there is autism or other ND conditions in certain groups.
I'm absolutely not saying all ND people. I have family who are ASPD from my lifelong experience of them, and they are certainly NT.
How you figure out what is what is incredibly difficult. We just don't have a good enough approach to assessing and flagging ASPD. I believe therapists will often miss it and may be out their depth dependant on the severity and capacity to manipulate in certain ASPD people.
The horrible reality imo is that with an ASPD, the capacity to improve or for sustainable change, to me, feels futile and actually impossible.
