Abstract
Predicting the evolution of epilepsy is of obvious importance for patients and their families. Value of electroencephalography (EEG) is extensively used in the diagnosis of epilepsy yet its role as a prognostication method remains unclear. The aim of the present retrospective study is to investigate the relationship between serial EEG recordings and long-term clinical and social outcomes in a cohort of patients with epilepsy. Thirty-nine epileptic patients were monitored clinically and with repeat EEG recordings for more than 15 years. All patients who initially had epileptiform discharges ended up with poor or moderate seizure control whereas more than half of the patients with normal initial recordings had good clinical outcomes and satisfactory social adjustment. Deterioration of the recordings over time was associated with unfavourable results in a significant proportion of patients (90%), while stable or improved EEG findings predicted a favourable outcome. It is concluded that serial EEG recordings can be used in the prognostic evaluation of epilepsy.
Highlights
All patients were diagnosed and evaluated lagen disease, heart disease, etc.). for their epilepsy in our outpatient clinic
The value of electroencephalography (EEG) had two regular appointments and at 16-channel Era (Ote Biomedica), and an Elemaafter fifty years of continuous worldwide appli- least one EEG recording on a yearly basis
The prediction of the long-term evolution of epilepsy is an issue of great significance for patients, care-givers and treating physicians alike
Summary
Thirty-nine epileptic patients (22 males and 17 females, aged 41 to 57 at the end of the study) who were followed up at the EEG laboratory of the Department of Neurology, Athens Medical School, Eginition Hospital were included in the study. In accordance with local regulations, all patients attending our clinic had their first epileptic seizure after the age of 15 years. Patients had a history of febrile convulsions, predicted a favourable outcome. It is concluded All procedures were performed in compliance head injuries at an earlier age or possible perithat serial EEG recordings can be used in the with institutional guidelines for the privacy of natal injury. The study has been approved by logical symptoms and signs or suffered from the ethical committee of the Aiginition mental retardation, significant psychiatric or Hospital
