Cerebral edema and neurological function in human beings

The assumption that cerebral edema necessarily results in neurological deficits was investigated with the computerized scan. Four cases are cited to demonstrate that normal function can be preserved in spite of marked focal edema. Quantitative analysis of the amount of edema showed a large increase in the local water content, while neural activity was apparently not adversely affected. (Neurosurgery, 6: 249-254, 1980)
