摘要

Brain edema is a major contributor to poor outcome following ischemic and hemorrhagic stroke. In animal models, edema has historically been quantified as a change in brain water content expressed as a percentage of wet weight (% water content). As described in this communication, this number can be misleading, as “small” changes in percentage of brain water content actually reflect much bigger changes in brain swelling. Using either water content, expressed as grams per gram of dry weight, or a measure of brain swelling better reflect the impact of edema after stroke and brain injury.
