[EEG findings in patients with a kidney transplant]

For a sample of 22 men and 9 women, 24-59 years old, closed-eye-EEGs were registered three times a day: at 7 a.m., at 1 p.m., and at 7 p.m. Simultaneously with every EEG-registration the body temperature was measured. Apart from traditional visual evaluation every EEG was recorded on tape for computer processing. For comparison served corresponding data of 17 hemodialysis treated (HD), and of 11 hemofiltration treated (HF) patients, of 12 healthy young volunteers (J), and of 10 healthy old volunteers (A).

As the illustration shows, the occipital peak-frequency (F) of the renal transplant recipients (NT) resembles that of the J and exceeds negligibly that of the A, whereas considerable differences are revealed compared with the peak-frequencies of the HD- and of the HF-patients. Statistically the peak-frequency of the NT-patients occipital and parietal turns out significantly higher than that of the HD- and HF-patients. According to these findings intraindividually in 5 of the former HD-patients after transplantation a remarkable increase of the peak-frequency is visible. In addition to this the figure demonstrates, that only in the healthy volunteers the peak-frequency (F) ascends corresponding with the body temperature (T) from the morning to the evening, while in the NT-patients similar increases scarcely are recognizable. In contrast to this in the HD- and HF-patients the body temperature rises in the normal way, but there is no corresponding variation of the peak-frequency. In the NT-patients pathological patterns are less frequent than in the HD- and HF-patients, but nevertheless more frequent than in healthy persons.(ABSTRACT TRUNCATED AT 250 WORDS)
