| Abstract: | Of forty children having undergone two or more years ago an irradiation of the brain case with cobalt-60 delivering doses between 1800 and 2400 R TD (n = 20) or a dose above 3500 R TD (n = 20), as a matter of fact ten presented pathological EEG findings which, however, may be interpreted as genetically determined characteristics, or instead in connection with a recurrence of the tumor just manifesting itself, or else as the consequence of a residual tumor or of the surgery performed. Pathological EEG findings on the account of radiation therapy apparently are much less frequent than morphological changes of the brain after radiation therapy. It is not necessary to assume that the latter need always have an effect upon the function of the infantine brain. |
