stroke measurement

Hi Does anyone know how a strokes severity is managed? This question came on a stroke forum and piqued my interest. After some research there is really nothing out there. For example 1-10 scale
one-size-fits-all
Cancer has stages and at least they tell you where the cancer is located.
I have heard of a couple of people who were told ccs of dead area but even they were not told where the dead area was. but alas I was told nothing.
from 1998
American Heart Association Classification of Stroke Outcome Task Force has worked to develop a valid and reliable global classification system that accurately summarizes the neurological impairments, disabilities, and handicaps that occur after stroke.
For stroke survivors to receive the best care, a comprehensive stroke outcome classification system is needed to direct appropriate therapeutic interventions
And these scales are based on deficits rather than the parts of the brain that were damaged. Here is the classfication system
I agree with the need but it is based on impairments rather than brain location and penumbra damage vs. dead brain so I think this is actually rather useless. I don't think this ever gained acceptence since no survivor has ever mentioned it.
