There is a nexus around neurodivergence, trauma, and the "cluster B" personality disorders. My own hypothesis is that it's all the same structural malformation, exacerbated by trauma and manifesting differently based on developmental inputs and levels of childhood trauma. I'm diagnosed BPD and in remission, my mother absolutely rejects that diagnosis and still maintains that I'm actually ASD because the borderline diagnosis to her means that she failed as a mother.
