When the blood supply to a portion of the brain is blocked this causes a stroke.

neurons die as a result of cessation of oxygen supply and dehydration causes blood viscosity. therefore if blood is viscous there would be poor oxygen supply to the brain because the hemoglobin in the blood carries the oxygen we require for cellular respiration.
Insufficient supply of blood to the brain can cause fainting (syncope) or a more severe loss of consciousness.

The brain needs so much blood because it needs a constant supply of it to keep up with the neurons metabolic demands. 20 percent of the blood that comes from the heart is pumped directly to the brain.
Cerebrospinal fluid is what provides as a "cushion" for the brain. (I don't understand your question regarding blood supply)
