[EEG in Parkinson's disease and cerebral hypoxia (author's transl)]

EEG-findings of a group of 95 patients suffering from Parkinson's disease were related to accompanying diseases inducing cerebral hypoxic hypoxidosis. The EEG in 59 to 74 per cent of our patients was abnormal but the changes were not specific. There was a correlation between age and EEG-abnormalities. On the other hand no association could be seen between EEG-changes and duration of the Parkinson's disease. At least 74 per cent of the patients suffered from concomitant cardiovascular complications and 36 of them had a severe pathologic EEG as well as a pathologic ECG. The results lead to the conclusion that in treatment of parkinsonian patients attention is to be paid to accompanying diseases as heart failure, angiopathy or anemia.
