Abstract
Changes in brain function of 9 children (6 males and 3 females) ages 7 to 14 years (mean 12 years) with end stage renal disease (ESRD) were investigated before and after haemodialysis treatment, utilizing computer assisted spectral analysis of the scalp-recorded EEG. A control group of age-matched healthy children was studied as well. Statistical analyses demonstrated that ESRD children exhibited more Delta and Theta activity, less Beta activity, a slower dominant frequency of the Alpha activity as well as a slower centroid of the total activity before treatment than the controls. These findings suggest a deterioration of vigilance as characterized by Head.13 Haemodialysis decreased slow activity and increased Alpha and Beta activity, thereby inducing an improvement of brain function.
