That's a really reductive oversimplification of the situation.

How does it account for PTSD sufferers at all?

That's nothing to do with it...

You could just as well ask how it accounts for penguins riding unicycles.

The only brain change with PTSD is the hippocampus, they've explicitly looked for changes to the amygdala and there isn't any.

If you want to split hairs, there is a statistically insignificant change, but that makes it smaller.

No, there are many brain changes involved with PTSD including the prefrontal cortex and the study clearly didn't take it into account.

I didn't even say anything about the amygdala. I said PTSD. Don't put words in my mouth.

Maybe you should have explicitly stated your point?

And I don't see anything in your link about subsequent changes to size or activity of the prefrontal cortex due to PTSD.

Although I admittedly just skimmed it.

So if that links backs up your argument (whatever that was) please link the relevant part.
