EEG microstates analysis in patients with epilepsy

Popis výsledku v původním jazyce

Analysis of microstates in electroencephalographic recordings (EEG) is a promising topographical method that is currently being studied for diagnosis of neuropsychiatric diseases. The aim of our study is to describe the feasibility of using the microstate analysis of EEG for examination of the epileptic patients. The EEG recordings were measured on patients with epilepsy and on control subjects (with no epileptic pathology). We calculated the global field power (GFP) curve to extract microstates from the EEG recordings. We take local maxima (peaks) of GFP curve to create amplitude topographic maps. Four microstates can be found or is proved to be found in physiological activity, sleeping, and in some pathological activity (schizophrenia). Our goal is to find out if the same microstates also occur in patients with epilepsy. Our assumption is that, if all four identical microstates are present in EEG with epileptic activity, parameters of these microstates should differ between the EEG of a healthy individual and a person suffering from epilepsy. We observed that the microstate 1 seems to have higher occurrence for the non-epileptic controls than the patients with epilepsy. The duration of the microstate 4 seems to be higher in the epileptic patients than the non-epileptic controls. We have found that there is a significant difference in the duration, occurrence and contribution of the amplitude topographic maps between the non-epileptic controls and the patients with epilepsy.
