Blood Hyperviscocity and Stroke

There are certain diseases in which blood becomes thick. This causes it to flow slowly, and to, at times, stop flowing altogether. And under the right conditions blood has a serious tendency to clot inside the arteries, especially when they are affected by atherosclerosis.

And when this occurs in the brain, it can lead to stroke. This can occur under conditions of extreme dehydration, and when blood cells are over-produced, such as is the case in the leukemias, thrombocytemias and polycythemias.
