Bei Frauen ist die Wahrscheinlichkeit, eine posttraumatische Belastungsstörung (PTBS) zu entwickeln, doppelt so hoch wie bei Männern | Das Team stellte fest, dass der Grad der K27-Polyubiquitinierung im Hippocampus von Frauen nach einer Angstlernerfahrung anstieg, bei Männern jedoch nicht | „Möglicherweise brauchen wir unterschiedliche Ansätze für Männer und Frauen [with PTSD]“

Repost of [**this**](https://www.reddit.com/r/science/comments/1u14yft/a_virginia_tech_study_found_that_the_female_brain/) as it broke Rule 3: *It must include at least one result from the research and must not be clickbait, sensationalized, editorialized, or a biased headline*
Wonder if it has to do with women being generally smaller and more vulnerable to attack than men. Because we know we’re better off choosing the bear, right?
„we may need different approaches for males and females“ wow, maybe scientists have finally figured out that only studying white men is a bad way to do science!
*Using rats, researchers examined two regions of the brain tied to fear and memory: the hippocampus, which helps connect experiences to places, and the amygdala, which processes fear and emotion.*
*The team found that levels of K27 polyubiquitination rose in the hippocampus of females after a fear-learning experience, but not in males. When researchers reduced K27 ubiquitination using a gene-editing technique, they found that females had trouble holding onto the memory, while males were unaffected.*
*“Just because males and females can learn or remember the same experience doesn’t mean how their brains get there is the same,” Jarome said. “If we’re developing treatments for conditions like PTSD or trying to improve memory, we may need different approaches for males and females.”*
*In the amygdala, the team saw no significant change in K27 polyubiquitination levels after the fear-learning task.*
*“That was a bit surprising,” Jarome said. “We would typically expect the amygdala to be where you’d see a lot of this happening because it’s so important in emotion. But we saw it in a broader memory region, and it was specific to one sex.”*
*The researchers also found that K27 polyubiquitination attaches to a protein called ACAT1 in the hippocampus during memory formation in females. ACAT1 has been linked to Alzheimer’s disease, which affects the hippocampus and disrupts memory, raising the possibility that it may play a role in both memory formation and loss, Jarome said.*
We know blank slate is bs
Deliberately misleading headline.
A study measuring protein levels in rat brains tells us nothing about the differences between human men and women.
I’m not sure why they are conflating K27 polyubiquitination levels with PTSD. PTSD is diagnosed by the presence of behavioral factors, not the levels of a specific protein.
I bet this has something to do with why our wives always wander into the room and turn the stereos down.
Also anyone notice that even in this article about women developing ptsd twice as much, the end statement is still different approaches for males and females? Why do they always put men first even in conversations about women, ahhhh
This has been observed in psychopaths where they have a different response to stressful and traumatic imagery. While other people are observed to have an elevated heart rate, rapid breathing and indicators of stress, psychopaths have the opposite response and are calm.
PTSD is diagnosed just as much in men as in women. It’s the rare occasion where the ratio is 50 50. PTSD is diagnosed by presenting symptoms and not specific biomarkers.
I hate the wording of this.
PTSD isn’t just „fear.“ It can manifest as aggression, depression, and even mimic mania. Now, if we’re going to look at the deeper things, like what women are exposed to that makes PTSD more prevalent, then we’re getting somewhere.
