To me, you need to have many MRI's that show 'before trauma and after trauma' to compare... I don't think that's available. |
Thanks mac, sorry I didn't respond earlier. Makes total sense, what you're saying. I've wondered all that stuff myself. And yes I never had a brain scan before the trauma, so who knows really what my brain looked like then.

As far as shrinkage being determined though, in my case there definitely is shrinkage on the right side of the brain, it is 18% smaller than the left, which is considered a big difference, and abnormal. In a "normal" brain, both hemispheres are nearly identical in volume. But why I have that shrinkage is debatable, you're absolutely right there.
I wish I wasn't so worried about it, but Anthony is right, better that I know as much as I can so I can deal with it as best as possible.
