title: [EEG studies before and following hemofiltration].
abstract: For a sample of 8 men and 3 women, 47-80 years old, closed-eye-EEGs were registered for the first time in the morning before hemofiltration treatment, again thereafter at 1 p.m., and a third time at 7 p.m. The day after treatment EEG-registrations were conducted at the same times. Apart from traditional visual evaluation every EEG was recorded on tape for computer processing. Simultaneously with every EEG-registration the body temperature was measured. For comparison served corresponding data of 17 hemodialysis patients, and of 10 healthy old and 12 healthy young volunteers. The peak-frequency of the hemofiltration patients turned out significantly slower than that of the healthy persons and of the hemodialysis patients. While in the healthy volunteers the peak-frequency increased corresponding with the body temperature from the morning to the evening, the hemofiltration patients lacked such a correlation, although their temperature ascended in the normal way. As to the circadian variations of the activity in the diverse frequency-bands, the hemofiltration patients, and to a less degree the hemodialysis patients, showed especially in the day after treatment distinct deviations from the healthy volunteers.
