I would, with no basis whatsoever but guesswork, hypothesize that PTSD is one of those things where the stressor might vary culturally but the disorder itself is pretty universal. Like, a modern, urban child might very well have a traumatized response to seeing an animal slaughtered; a medieval, rural child very probably would not.
But I'd also guess that 'seeing a lot of people around you dying' and 'being in acute fear for your life' are, if not universal, than very culturally common traumatic stressors.
