Title: The efficiency of EEG-monitoring in a diagnosis of epilepsy
Abstract: The purpose of this study was to determine the effectiveness of EEG monitoring in the diagnosis of epilepsy. We studied 94 PE. All patients had an EEG with using functional loads (eye opening, photostimulation, hyperventilation), 31 people (14 men and 17 women, mean age 27 years) were conducted to EEG-monitoring with night sleep deprivation, a few days after EEG. We used the 21-channel electroencephalograph ";“Telepath";” for the EEG. The electrodes were located on the surface of the head of the International System ";“10–20";”. The PA on EEG was detected only in 58.51% of patients, in 41.49% of PE - was absent. The EEG-monitoring allowed additional PA detection in 25.51% PE, in 54.83% of patients, paroxysms significantly increased during sleep and in areas of awakenings. The PA has become more frequent, increased its amplitude and duration, it has become significantly more likely to include epileptiform patterns as spikes, sharp waves, complexes ";“spike-wave";”, ";“multiple spike-wave";”, ";“sharp-slow wave";”. The EEG-monitoring in 45.16% of PE allowed to specify the shape of the PA, the localization of epileptic focus, the level of involvement of the brain stem. In general, we can talk about increasing the efficiency of diagnosing epilepsy by 70.67% using the EEG monitoring with night sleep deprivation.The EEG-monitoring is an effective method for the diagnosis of epilepsy. The advantage of this method is a significant increase in the quantity and quality of clinically relevant information that makes it possible to significantly improve the accuracy, reliability and informativity of electroencephalographic diagnosis of epilepsy.
