For those interested, the stories from the previous thread with Dr. Jacob Da Costa and his study on Soldier's Heart - which in our timeline became the first real study on stress but which TTL will be extended, because of the greater emotional toil on the country and connection with a few ambassadors, into greater understanding of trauma - can be found

Dr. Jacob Da Costa smiled sadly at the coffee mug on his desk. He lifted his eyes as a familiar face entered. He grinned. "Mr. President."
"I can't stay long," Lincoln said as he entered, "but I wanted to give you at least a little good news myself as I visite4d some of the last of the soldiers here."
"Here" was Satterlee General Hospital in Philadelphia, a medical hospital which had opened in 1862. With the war now more or less over - though there were still slaves being told they were free even now, in the fall of 1865 - they had been told that the hospital would be closing.
LIncoln continued. "This has become its own little town of sorts, given how many were treated here. some of it is being transferred to a couupe of other area hospitals. Indeed, a small portion may be donated to the Institute for Colored Youth where Mr. Catto teaches."
"Good to know." Da Costa picked up his heavy coffee... well, people would later call it a mug. "Look; a tiny imprint from how often this or some other thing has sat here as I worked late into the night."
"Your work will be remembered. I still remember a few months ago when you interviewed me, as it were, as I was visiting our men. Rather than the lengthy interview regrding my memories of the attempt on my life, combined with wrestling exploits when I was young, you began asking me thigns like what I'd had for breakfast three days earlier. I thought it quite odd, but one never knows what will provoke a cry of 'Eureka' - the scientific mind puts things together in ways we who are not enamored with such gifts cannot comprehend."
"Indeed. I shall publish concerning this heart condition among soldiers either next year early the following." He would, indeed, publish it in 1867, after a year of proofreading and so on. "That will keep me busy. However, I continue to mull over this concept of anxiety. I find the concept fascinating, and feel there may be some sort of link between the heart and mind, between this heart condition among soldiers and whatever causes that little girl I mentioned last year, that child I learned about from the Napoleonic Wars, and others, children and adult, whom I have heard about to have these... symptoms."
"Keep upthe good work. I am certain that whatever school or hospital you work at next, you will be of great service."
"Thank you. I plan to go back to Thomas Jefferson University and teach. How long until the embassies start moving back?"
"It will be a while yet, but thankfully, we shall have a new birth of freedom, coupled with a brand new capital, produced by free men, black and white. It will be glorious to see the races united, freely contributing to it," LIncoln proclaimed.
"That it will.
------------------
Da Costa stopped in to see the stafffrom the Russian Embassy some days later. "This December wind is biting; but probably still better than the chill of MOscow," he remarked.
It certainly is. Do you have any more requests concerning the Napoleonic Wars? Unfortunately, when we contacted some of our leading doctors, we were not able to find anything other than what we have given, but I do have some friends who served in the Crimean War."
"Perhaps - if you can give me a summary of what you might be able to find, it would be helpful."
"Are you after your work is done, or going back to teaching?"
"Still practicing a little more, there are some soldiers who still have some very deep physical scars. It astounds me what one thing smashed against someone in close-quarter combat can do," he said idly.

Dr. Da Costa had lost a two-month old boy, though he and his wife had one child. The couple had attended a Shakespearean play one evening and happened to see a familiar face.
"Mr. President," Da Costa called, waving to him. As the president and his wife came over, Da Costa introduced his wife. ""I knew that you enjoyed the theater;I would not have expected to see you here."
"After what I have been through already, a trip to the theater can't help but be relaxing." Lincoln chuckled. "I was considering another play as Mary and I chatted; those things you mentioned about soldiers and others seeing things that were there long ago reminded me of Lady MacBeth with that spot on her hand. Shakespeare was a genius when it came to understanding the human condition and utilizing it in his plays. I have lately had the time to consider that Ophelia's is a story as tragic as Hamlet's, for had she merely waited, she could have married Fortinbras or, if he was too old, his eldest son and become Queen herself. Just as we did not give up but hung on till the traitors were defeated, and we shall hang on until the peace is won, too."
"A fascinating observation, Mr. President; thank you."
-----------------
Da Costa relaxed in his office soon after theNew Year, 1866, dawned. He picked up his glass and mulled over all of the various factors in his mind, all the information he was collecting. Two little girls, half a century apart,fixated on a battle in the same way the soldiers he'd observed had. Scary dreams reported by soldiers and civilians alike. How could the heart impact the mind in some of these ways, when it was not just soldiers, but civilians. Especially, from the few inerviews he'd done with USCT soldiers, former slaves, who had a few of those symptoms - but not the Soldier's Heart - stemming frmo peacetime.
Although, from what he'd been hearing there had been no such thing as peace for the slave.
But, that was for another day. Slavery was dead; dead as a doornail. But those symptoms... was it something different, or... was it connected?
Indeed, could it be not only connected to Soldier's Heart, but actually the catalyst? And if it was the catalyst, then how?How did something produce Soldiers' Heart in soldiers, dramatic re-creations and terrifying hallucinations in children, and so on?
He'd slowly been able to help that one child to focus on other things, the power of prayer was helping with the nightmares, even trying to teach her to control them. that would be an interesting tact. But to treat it more easily, he needed to figure out how something int he brain could be a catalyst for all those myriad things.
he gazed at the ring as he picked up his heavy cup. President LIncoln was right; Dr. Da Costa, too, had pondered Lady MacBeth at times. He thought of the scars of not only that spot on her hand, which had been self-inflicted through her joining in treachery, but also those inflicted by battle, both external and...
Wait. Where had THAT come from?
And yet, as he pondered, he wondered about the brain. Could it be that somehow, some sort of imprint - like memories, but somehow... stronger - could foist itself onto the brain to such an extent that it affects the rest of the body?
He gazed at his stack of papers from the subjects who had sat waiting for him when the firecracker was set off - a study he would also publish sometime. Expectations but also reactions among athletes and non-athletes, male and female, soldiers and non-soldiers, adults and children, all with a myriad of combinations of each in the subjects - if one counted the few 13- through 15-year-old Confederate soldiers brought in near the end of the war - and test and control groups. Perhaps this, too, tied in - there went another round of his walking to various embassies while they remained in Philadelphia to get more possible studies and more European colleagues to correspond with.
He gazed at the ring on his desk left by the cup, and pondered... what if somehow, there was a method to all of this? A scale by which one could measure the impact of... these imprints, he supposed he would call them? And what if these imprints were the cause of these myriad cases of what he'd thought was "just" Soldier's Heart, but which were clearly impacting civiliants, too. And if too consistent an injury to the brain came, or too sharp of an injury at once, and it led to that imprint which led to...
He continued to stare at the stain on his desk as he pondered the anxiety reported by soldiers and civilians alike. Slowly, the seedling of an idea germinated in his mind, till at once, he slammed the cup down and let out a shout that reverberated into the PHiladelphia night.
"EUREKA!"
------------------
A/N: Dr. Da Costa didn't just magically come up with the idea of PTSD; but this is a logical step. Indeed the idea of an "imprint" will change from somehow physical (if microscopic) once the chemical and electric processes are discovered. Rightnow, it's more like a conceptthat will make sense to others, they'll just keep trying to figure out how those imprints get there.
However, the greater number of civilians as well as soldiers being seen with the same symptoms, his access to embassies from other nations as well as the President and other government leaders, and indeed perhaps even the greater carnage forcing him to work later and have that stain on his desk, have allowed his study on anxiety, which will be published in 1871 as OTL, to be changed and become more tied in to the stress he's observed here, as well as seeing a more direct link with the mind, and gathering correctly that what happens in the mind, psychologically, is affecting the rest of the body.
So, what has happened is that a few tweaks allowed his study into anxiety to nudge him toward the idea of post-traumatic stress, as well as to allow his concept of imprints caused by various things to become a more sensible basis for psychoanalysis, potentially, once that is developed, rather than Freud's more intense sexual stuff.
Edfit: It will also help to explain the desire for nostalgia that soldiers had afterward, as it is a familiar, safe "imprint" - but that will be for later studies.
