Quantitative EEG abnormalities and asymmetries in patients with intracranial tumors.
Quantified EEG data of 50 patients with intracranial tumors (T) were compared to the data profile of 60 normal adults (N), using univariate and multivariate statistical analyses. EEGs were recorded from 16 derivations. Twelve spectral parameters were computed from each lead and used for statistical comparisons. The number of significant deviations (P less than 0.05) among univariate features did not separate the T subjects from the N subjects with an acceptable sensitivity. A significant improvement was achieved by using multivariate features and particularly asymmetry multivariate features which detected 49/50 of the T subjects. The proportion of correctly lateralized tumors was 43/48.
