An algorithm for detecting events in video EEG monitoring data of patients with craniocerebral injuries

One of the problems solved by analyzing the data of long-term Video EEG monitoring is the differentiation of epileptic and artifact events. For this, not only multichannel EEG signals are used, but also video data analysis, since traditional methods based on the analysis of EEG wavelet spectrograms cannot reliably distinguish an epileptic seizure from a chewing artifact. In this paper, we propose an algorithm for detecting artifact events based on a joint analysis of the level of the optical flow and the ridges of wavelet spectrograms. The preliminary results of the analysis of real clinical data are given. The results show the possibility in principle of reliable distinguishing non-epileptic events from epileptic seizures.

This chapter discusses the experience of a Neurologist with a patient who presented with a history of three bilateral convulsive seizures over a period of several months. The Neurologist started him on an adjunct antiepileptic therapy and he became seizure free. However, the situation changed dramatically after a stable period of twelve months. He started having seizures again and his mother was able to recognize that these seizures were different from those he had had one year earlier. Prolonged video-EEG monitoring confirmed the diagnosis of Non-Epileptic Seizures (NES). The Neurologist then referred the patient to a Clinical Psychologist, who used Cognitive Behavioral Therapy and taught him some techniques to cope with the condition. Eventually, the patient and his family were able to manage the NES better with the help of the psychologist. The patient reported a significant improvement clinically with less frequent NES and they learned how to manage the situation without visiting the Emergency Department.
