Look I have a hard time believing it. I mean yes those cases truly happened and the CBF fluid truly filled those zones. However my question is, can an IRM see beyong the a CBF fluid overload? Maybe there was just a shallow CBF overload and deep inside the neurons/synapses where still working. Or maybe not and those people really have lost 90% of their neurons, it's unfortunate no one care enough to fact check given this is essential towards understanding what is necessary in the brain.
