| Popis: | A predictable relationship between Verbal Comprehension deficits and EEG abnormalities in the left hemisphere of patients with focal and generalized seizures has been reported. A relationship has also been reported between Perceptual Organization deficits and right-hemisphere EEG abnormalities. To extend and verify these findings, the performance of the left- and right-hemisphere seizure groups were compared using multivariate analyses of variance on three factors of cognitive performance: Verbal Comprehension, Perceptual Organization, and Freedom from Distractibility. Twenty-eight right-handed male subjects with focal seizures lateralized to either the left or right hemisphere by EEG were studied using the Wechsler Adult Intelligence Scale. Our initial hypotheses that individuals with left-hemisphere seizure foci would perform significantly more poorly on Verbal Comprehension tasks and individuals with right-hemisphere seizure foci would perform significantly more poorly on Perceptual Organization tasks were not confirmed. The data suggest that theoretical bias may obscure the mechanism of cognitive dysfunction in epileptic populations. |
