Another patient has the same symptoms but different flow, and a third had different symptoms but similar flow. What exactly have the brainscans told you? - Oh, and how did you decide what were 'symptoms' in the first place? @maciejwrotek Let’s say you have a patient with symptom X, and pattern A of bloodflow to part C of the brain.

Do I have dyslexia or did I fall behind in school because of my homelife? Am I delinquent, or am I trying to fit in with the cool kids who offend their parents with tokenistic rebellion? - Oh, and am I manifesting Resistance by asking these questions?

Would certainly cause lethargy...shortly followed by death. - If you mean hypoperfusion to every part of the *brain*...then you'd get brain death, or at least vastly reduced function, possibly to vegetative levels. Not depression. @maciejwrotek Global Hypoperfusion would mean decreased bloodflow through every part of the body. Would certainly cause lethargy…shortly followed by death.

For example caffeine alone at 250mg produces 22-32% decrease in cerebral blood flow. and u r still alive. But caffeine increases glucose utilization. @KapitanoStuff No, brain regulates functions by redistributing circulation.

Given the complexity of brain bloodflow, the imprecision of fMRI and the variability between patients, even those with identical symptoms (which never happens) will have markedly different flow patterns, so how do you correlate flow with symptom? How do you decide which flow aspects are significant, which are abnormal, which are relavant, and what is a symptom in the first place? @maciejwrotek Ok, I won’t question the figures, but they still don’t answer the original question.

I don't know if imprecisions are relevant, but i know that PET scanner shows 30% decrease with caffeine so it is useful. It is too complex try to understand where decreased blood flow causes what symptom. U simply correct it, symptoms dissapear, and then u can study details. @KapitanoStuff There must be a baseline for brain hydration and u go from there.
