Hypertensive disease and cerebral oedema.

Abstract
Studies indicated that deep white matter of the brain has a significantly higher water content in hypertensive individuals than in normotensive persons. This deep white matter is most specifically affected in cerebral edema. The water content and histological appearance of the cortex, arcuate white matter and corpus callosum were essentially the same. In general, hypertensive individuals tend to develop cerebral edema. Occurrence of this phenomenon is not limited to cases of malignant hypertension or of hypertensive encephalopathy.
