I have often wondered why the prisoners of concentration camps didn't all have PD, those that lived, that is...not that there were very many of them. Talk about daily chronic stress of the worst kind, surely that would open the BBB like a floodgate? So why weren't the allies, when they liberated the camps, greeted by a crowd of PWP?

The only thing I can think of is that those poor prisoners were starved, many to death, in reality, so perhaps the caloric restriction staved off the PD? I don't know, but I have often wondered about this, yet cannot find any stats for how many concentration camp survivors either had PD when liberated or later got dx'd with it (and if they got it later, how long after liberation).
