Epilepsy is one of the most common neurological disorders, approximately 1% of people in the world have epilepsy, 25% of epilepsy patients cannot be treated sufficiently by any available therapy. Epilepsy is caused by abnormal discharges in the brain, thus EEG has been an especially valuable clinical tool for the evaluation, detection, and treatment of epilepsy. Through EEG recordings, a number of systems which can release drug or give an electrical stimulation to suppress the seizures have been developed and under clinical operation for years. However, a robust device has not yet been developed which compute quickly and fast enough to action to meet immediately pathological changes of different types of seizures in human.
In this study, we research multi-type epilepsy diagnosis that can be applied to control the multi-type epilepsy with different method. We present a three-type epileptic diagnosis method, with using permutation entropy as the complexity index and spectrum band power with RBFSVM classify. The average accuracies of the RBFSVM reach to 79%. The detection rates of temporal EEGs can reach 97.6%. However, if we distinguish temporal EEGs (Set C) and non-temporal EEGs (Set A and B). The average accuracy can reach higher than 97% with RBFSVM. The classification results can be utilized to a system to determine what type of epilepsy when patients have mixed epilepsy.
In the on-line detection, the results of the feasibility of developing algorithms to detect seizures based on automated analysis of the spatiotemporal dynamical characteristics of EEG recordings. We present a reliable epileptic seizures detection method, with using approximate entropy as the complexity index and spectrum band power. We present an adaptive threshold method that reduced false alarm. We also selecting recurrent neural network to be classifier which can detect seizures in a short time while seizures onset. The method has tested on three types of seizures including long-term recordings, robustly. This method was shown with several aspects of advantages, including high accuracy of on-line seizure detection (reach 100%), low false alarm (below 2.5%). The seizure detection latency was not greater than 0.5 sec after seizure onset.
