Résumé

QEEG variables (5 activation. 2 relationship variables, 19 locations and 5 bands tip 10 64 Hertz) were collected under three activation conditions (auditory attention, visual attention and listening to paragraphs) on 84 subjects, consisting of 32 mild head-injured subjects (no loss of consciousness) and 52 normals over the age of 14. Additional variables collected included years of education, time since accident, sex, handedness and Shipley Institute ofliving measuses of IQ, verbal and abstraction scores. The results were encouraging for future development of a discriminant employing activation conditions, as the results varied from 88% to 100% correct clussification. Very few of the variables, which distinguished the groups under the three conditions or were used in the discriminant analysis, were shown to increase as the time since accident increased. This result, tentatively, indicates little effect of time on the improvement in the electrophysiological functioning of the brain. Time (spontaneous improvement) does not appear to heal the brain in any significant manner.
