True that "Some" people with BPD/EID may have attributes not listed in the DSM.. But this could apply to anyone with or without BPD/EID.
"Researchers believe SOME, may be related to sexual and physical abuse" but have yet to find evidence to support their theories.
There are many individuals with BPD/EID that do not have these attributes and many without BPD/EID that do.
Example: I have complex PTSD. Not BPD/EID, not bipolar, schitzoid behavoirs, etc. I have 45 years of a life of trauma, neglect and abuse.
I have shame, boundry and control issues, I am the oppisite of a narcassist, I never knew love and only knew I felt alone in life. I am a highly competent, intellectual, artistic individual. I am not a psychic. I do not prefess to be a mind reader of anyone's thoughts or emotions. Anyone can read anothers body language, see triggers and vulnerabilities if they seek these out. This is not a psychic gift.
This document from Dr. B... is simply put... just a hypothesis, a theory.
I do not say this to disrespect anyone or to create conflict. I say this to only express my view on the matter.
