[Initial EEG findings and the prognosis of epilepsy with generalized convulsive seizures].

Correlation between the initial EEG's and the prognosis of generalized convulsive seizures without other seizures was investigated. The subjects of this study was 437 epileptics with the period of the follow-up over 3 years. They were devided into 2 groups from view point of prognosis: "good prognosis" group, in which their seizures were completely controlled, the "poor prognosis", not well controlled. Most of the EEG findings appear to be not of value in predicting the prognosis. Exceptionally, however, the localized seizure discharged in the areas of T3,4, C3, 4 and P3,4 and 14--6 Hz positive spikes related closely to good prognosis, in the group of 7 to 12 years of the age.
