'There is no clinical research for any neuroprotective treatment in the first week'

A direct quote from 2 different neurologists from the local comprehensive stroke center(Sparrow) in response to my question to them on strategies to prevent the neuronal cascade of death.  2 separate presentations on 'Time is Brain'. This is precisely the problem, if you don't try anything nothing will ever get to that level of proof. They want results before they do any preventative work. Neither stayed around long enough for me to ask, 'Which comes first? The chicken or the egg?'
There are  these 31 hyperacute possibilities I'm going to insist my doctor give me the first week. 
I don't give a damn about no clinical proof, saving the neurons is worth the minimal risk these might have. I have to figure out a way to contact the stroke department head and ask why they aren't doing anything.
