Wang Xuefeng et al. EFFECTIVENESS OF MULTIPIE IN SUPPORTING THE DIAGNOSIS OF EPILEPSY[J]. Journal of Chongqing Medical University, 1990,(1):46-49. DOI: 10.13406/j.cnki.cyxb.1990.01.012.
we reviewed data from 547EEGs on 400 patients with epilepsy in order to determine the probability in finding the interictal epileptiform activity (IIEA) with serial EEGs. In 49.5% of our patients
the abnormaeity is present on the first record. In 53.5% by the second EEG
and in 54.25% by the third or above. There is relatively little yield to serial EEGs beyond this point. Patient’s ages
types of seizures and causes are negatively correlated to IIEA yield
