[Diagnostic and therapeutic attempts in so-called progressive dialysis encephalopathy].

57 patients from a chronic intermittent haemodialysis programme underwent 198 EEG examinations over a period of 5 years with follow-up. The results show that regular EEG examinations allow incipient dialysis encephalopathy to be recognized already at the pre-clinical stage. Whereas therapeutic measures always had no effect on the full clinical picture of dialysis encephalopathy and all patients died, in all but one case lengthening the dialysis time prevented the syndrome from reaching the clinical stage and in 6 cases EEG changes were reversed.
