The main objective of this study was to evaluate the possible alterations of the endogenous potentials by the kidney failure.
Method: Twenty-five patients were studied before and after hemodyalisis. The results obtained were compared with data collected from 25 healthy volunteers (control group).
Results: The comparative study between the control group and the patients revealed, both in Cz and Fz, increased latencies of N2 and P3. The values obtained after dyalisis indicated some improvement.
Conclusion: It was demonstrated that when we compare a group of healthy volunteers and a group of patients with kidney failure, all latencies were systematically increased in the group of patients. The same variables remained significantly increased after the hemodyalisis but at lower levels, what was probably related with some therapeutic effect of the dialysis. The data evaluated suggest that the latest phases of the cognitive process were more intensely disturbed.
KEY WORDS: cognitive potentials, kidney failure, hemodyalisis.
