The application of the electroencephalography (eeg) to predict and diagnose the epilepsy has been established for many years. but the clinical value of eeg prognostication for the epilepsy progression is also contradictory. the purpose of the present study is to explore the relationship between eeg recordings and early prediction of epilepsy progression in a cohort of epilepsy patients. ninety-eight epileptic patients were followed up clinically and with the routine eeg recordings for at least 13 years. all of the patients (26 patients) initially performed the epileptiform discharges ended up with poor or moderate seizure symptoms,while 58.8% patients with normal initial eeg recordings had satisfactory clinical outcomes. deterioration of the recordings over time was related with un-favourable results in a significant proportion of patients (85%). meantime,about half (49%) of the patients with normal initial recordings performed satisfactory clinical outcomes. a small percentage (4.5%) of the improved eeg evolution performed the un-satisfactory clinical outcomes,while 70.4% of the deteriorated eeg evolution. the preliminary findings suggest that the eeg analysis technology holds considerable promise and early predictive value for identifying seizure intractability,which could provide the guidance for treatment in the early period.
