Named conditions that are the result of exposure to psychopathic behavior of another person? Are there any recognized terms for conditions that stem from or are the result of exposure to  psychopathic behavior (by another person) that are distinct from those that might have predisposed the individual to it or made them more vulnerable to it?

In other words, something like a "post psychopath stress disorder"?

It would not have to be an official diagnosis, it's the only applicable tag I could find.
Environmental psychological conditions (conditions triggered by an event arising from another person's actions or other event external to the person) will have the same name irrespective of whether they might have been predisposed to it, more vulnerable to it, or neither.

The question is very broad as there are many different conditions which can arise, which actually can be any condition within the spectrum of environmental psychological disorders. There is no such disorder as "Post Psychopath Stress Disorder" but psychological conditions can include Post Traumatic Stress Disorder, Anxiety, and Vicarious Trauma.  There can be many others arising from the physical and/or mental actions of the psychopathic individual.
