[Psychometric and electromyographic studies in patients with chronic uremia subjected to periodic hemodialysis]

Twenty-five patients suffering from chronic renal insufficiency and who had been undergoing dialysis for a long time were tested on the Wechsler-Bellevue Intelligence Scale with a control of twenty-five subjects of the same age with a comparable educational and social background. The results of the statistical analysis of the difference between the two groups demonstrates a significant psychological deterioration in the group of uremic patients which was particularly noticeable in the performance test. The rate of deterioration was not significantly related to the duration of the dialysis. At the same time electromyography (motor conduction velocity of the S.P.E. nerve) show in 40% of the uremic patients evidence of neuropathy.
