This is why nothing has changed on PTSD research. They did it again. Over and over and over again, repeating studies other researchers discovered over 30 years ago! And I thought you couldn't get into MIT unless you were able to read?
This is the headline
MIT: PTSD could be prevented
And this was the "shocker"
“That was really surprising to us,” said lead author and MIT postdoc Michael Baratta. “It seems like stress is enabling a serotonergic memory consolidation process that is not present in an unstressed animal.”
Yep, they blamed serotonin
Blame it on the serotonin
The specific pathway of this disease involves a part of the brain known as the amygdala, an almond-sized structure involved in responding to and remembering stress and fear. In mice with chronic stress who experience a trauma, a neurotransmitter known as serotonin acted on the amygdala to promote the process of memory consolidation. (Memory consolidation is the process by which short-term memories are turned into long-term memories.)
This shows it goes back to 1972

Easy to see why everything I started reading over 30 years ago has been forgotten. Guess there is no money in actually paying attention to what was learned before the internet actually gave them the ability to learn what was done long before most of them were even born!!!!!
Military veterans
Information about PTSD in veterans of the Vietnam era is derived from the National Vietnam Veterans Readjustment Survey (NVVRS), conducted between 1986 and 1988. The estimated lifetime prevalence of PTSD among American veterans of this war is 30.9% for men and 26.9% for women. An additional 22.5% of the men and 21.2% of the women have been diagnosed with partial PTSD at some point in their lives. The lifetime prevalence of PTSD among veterans of World War II and the Korean War is estimated at 20%.
And this shows who started all the research new researchers have avoided at all costs,,,and I do mean costs since they get paid to do new research no matter how many times it has been done before.
Causes
When PTSD was first suggested as a diagnostic category for DSM-III in 1980, it was controversial precisely because of the central role of outside stressors as causes of the disorder. Psychiatry has generally emphasized the internal weaknesses or deficiencies of individuals as the source of mental disorders; prior to the 1970s, war veterans, rape victims, and other trauma survivors were often blamed for their symptoms and regarded as cowards, moral weaklings, or masochists. The high rate of psychiatric casualties among Vietnam veterans, however, led to studies conducted by the Veterans Administration. These studies helped to establish PTSD as a legitimate diagnostic entity with a complex set of causes.
