 | | Research conducted at UB suggests that high-altitude cerebral edema is caused by a disruption in the blood-brain barrier, the specialized layer of cells in cerebral blood vessels that, under normal conditions, allow only certain substances to pass into the brain's circulation. |
 | | Krasney's research using sheep has shown that the symptoms of high-altitude cerebral edema are not caused by an inadequate supply of oxygen or glucose to the brain. |
 | | In addition, Krasney said, it is possible that, in the presence of hypoxia, another chemical messenger, cyclic guanosine monophosphate (cGMP), acts with nitric oxide, a vasodilator, to promote and sustain permeability of the blood-brain barrier. |
