Modern technology in long-term EEG monitoring (EEG-Holter) in neurology practice

Abstract

The work is devoted to application of ambulatory monitoring EEG (AMEEG) in neurological practice, its opportunities and restrictions are shown. The experience of AMEEG 87 patients with duration of recording from 3 till 24 hours in natural conditions of behaviors of the man in time of vigilance and sleep is generalized. The researches were carried out as is out-patient (48), on the house at the patient, and in patients: in wards of clinic (19), ICU (20). AMEEG was carried out on compact EEG system at small dimensions and weight (of the whole device 400 g.) “Encephalan-19/26” of firm Medicom-MTD (Taganrog), which allows to carry out simultaneous monitoring EEG of the data on 20 channels, and also on 6 additional channels monitoring ECG, breath, EMG, EOG, and special sensor of body position. At 36 patients surveyed for diagnostics epilepsy , the diagnosis epilepsy in 19 cases (53%) is confirmed, though on short registration of routine EEG were not the indications on presence epileptifom activity. In 16 cases (44%) was not of the indications on epileptyform activity and in 1 case there were marks, which were doubtful, and the further supervision and investigation was required. At two patients with syncope the condition show them cardiac nature and only in one case at AMEEG have revealed epileptic genesis of attacks. At inspection on a subject with insomnia and night nightmares in one case it were real parasomnia, in the other – the nature these paroxysm is shown the epileptiform nature, that has appeared obvious at long monitoring EEG, including and polysomnography. At ward monitoring at 5 of 8 patients the nature available paroxysms confirmed epilepsy. Monitoring EEG and polygraphic indications in ICU gives the important estimation of a condition and forecast of the patients who are taking place in areactive condition.
AMEEG considerably expands opportunities routine EEG and allows to receive the new information on a condition of the brain, helps to decide differential diagnostic tasks at paroxysm displays, gives opportunities monitoring of the patients who are taking place in areactive critical condition. AMEEG of sleep allows easily enough to carry out polysomnography investigation in a place of a presence of the patient, not resorting to bulky systems.
