[Current role of electroencephalography in the diagnosis of brain tumors].
The comparison of anamnestic and clinical findings and numerous others obtained by medical instruments of 204 patients suffering from cerebral tumour confirmed the high value of the EEG in detecting a cerebro-organic process. Normal EEG-results could be found in 10% of all patients only. Independent of kind and localisation of tumour the supratentorial area showed changes of background activity in 87% and focal findings in 78% of all cases. With so-called epilepsies due to a tumour, pathological EEG-results were found in 94% of all cases. The EEG, an inexpensive method which can easily and everywhere be applied and is also comfortable for the patients, will continue to exist in the pre-diagnostic stage and in the decision-making for other diagnostical measures.
