Re: PTSD....what exactly is it? Looking for info.
I won't call out any specific posts... but there were absolutely soldiers in past conflicts who suffered from what, today, would be called PTSD.
The effects were recognized after The Civil War where it was called "Soldiers Heart." The same effects were widely-studied after World War 1 where the term "Shell Shocked" came from. Trench warfare was so traumatizing, in fact, that some WW1 veterans were simply institutionalized, the shock from their trench experiences was so great and permenently debilitating.
The symoptoms were similarly an issue in WW2 where it was called Battle Fatigue. The most-widely remembered incident came from Patton's slapping a soldier, but it was also documented by Marine Robert Leckie in his memoir "A Helmet for My Pillow. A journalist before he became a Marine private, Leckie's documentation of his Pacific experiences are one of the most-hailed war memoirs for his ability to write with a journalists's eye. And and Leckie clearly describes his symptoms and experiences. Similarly Eugene Sledge's memoir, With the Old Breed, clearly documents his postwar issues of depression and other symptoms that would, today, clearly be recognized as PTSD. In both cases, the men found ways to cope. But that did not make it any less real.
Further, I grew up in a post-Vietman America where a real recognition of PTSD symptoms and effects was beginning to emerge. I starkly remember that every time a veteran committed the slightest infraction, it was being chalked up to their Vietnam experience and, while not called PTSD, the term Post-Traumatic Stress was starting to be used. For those who remember the movie "First Blood," one of Stallone's major themes in writing the movie (and creating the Rambo character) was the effects of PTSD and difficulty that soldiers of the Vietnam era were having re-integrating into society. There was more to Rambo than a good shoot-em-up... there was a major underlying theme of neglect and outright hostility against those who served by the American public... something that may well have magnified the effects.
Just by way of doing some digging into my book collection, these two cartoons, drawn post World War 2 by combat-cartoonist Bill Mauldin in his book "Back Home" (1947) I think illustrate exactly the sorts of things that today we would refer to as being associated with PTSD. And Mauldin was very tuned into the combat soldier and, later, the combat vet. Because he was one.
We look at WW2 now through a lens of nostalgia. But the realities for many of veterans was anything but nostalgic.
Perhaps, too, PTSD was not talked about or widely discussed during the Cold War stoicism of America (can't show any weakness to the Russians). And the Booming '50s was not where a new superpower wanted to talk about the horrors of war... And there was not a media or multi-media culture that made wide news out of something like PTSD. But just because it wasn't a topic of daily conversation does not mean it was not there.
I won't comment on PTSD from a medical perspective, because I am simply not qualified. But from an historical perspective, the documented effects that the OP was looking to understand have been around as long as modern warfare has existed. And perhaps longer. Call it what you will, but the effects of warfare on the human beings who serve their countries, have been documented for a long, long time.
It is only in recent years that, it seems, more is being done to support those who show the effects of PTSD. And they deserve everything a grateful nation can offer, in my opinion.
Cheers,
