title: Electroencephalography in brain edema (127 cases of brain tumor investigated by cranial computerized tomography).
abstract: Cranial computerized tomography (CCT) in permitting visualization of cerebral edema in live patients, allows for the first time valid studies concerning the role of reactional edema in the generation of EEG abnormalities related to expanding processes. The authors analyze the results of EEG and CCT in 127 patients presenting cerebral tumor(s), 84 of which were accompanied by reactional edema. The study leads to the conclusion (also demonstrated by certain animal work) that edema per se is only rarely responsible (9.5%) for the EEG abnormalities.
