Her doctor says she has Cerebral Vasculatis (I'm going to guess that's a typo and it should be Cerebral Vasculitis.) Since this story is just breaking, naturally all the facts aren't out yet. But I wouldn't expect to read all of the details anyway. There's only so much that will be released to the public.
we dont know how the neurologist came to the conclusion he/she did
No, we don't. And unless s/he speaks up, or is interviewed, we will never know. How does any doctor reach their conclusion? Also, the girl had very serious reactions to the injections. Not uncommon with vaccine injections, yet still severe. On the 3rd injection, she collapsed.
As an aside, I completely agree with your tagline. A new Dark Age is looming.
