[Significance of the EEG for the prognosis of therapy in adult epileptic patients].

The importance of EEG findings regarding prognosis of therapy and relapses of epilepsies is controversally discussed in the literature. On the basis of 495 patients being in attendance for many years there were some important indications for prognosis, for instance 59 percent of the patients with normal EEG at all times during the cours attained freedom from seizures for at least five years. The best possibilities for differentiation followed from EEG features during medication, especially from degree od disturbances of background activity. Only 13 percent of patients with more than slight disturbances in resting EEG remained seizure free for a long time. Also as a distinctly unfavourable sign proved the combination of generalized and focal epileptiform pattern.
