The method of multi-step dipole localization with potential charts preanalysis was applied to EEG spatial localization of discharge activity in 24 epileptic patients. The results were juxtaposed to the X-ray contrasting techniques and computerized tomography. Spherical symmetrical 8-layer head model was used to interprete the results. The data on(More)
A total of 27 patients with transitory global amnesia (TGA) in the acute and late (from 7 days) periods and 31 patients with dyscirculatory encephalopathy and subjective memory impairments (control group) were studied. EEG data and assessment of the P300 cognitive evoked potential wave established differences in the nature of beta1 activity between these(More)
The results of complex studies were used to formulate a concept of the development of neurological impairments in multiple sclerosis (MS). Acutely developing impairments to spike propagation, reaching the level of conduction blockade, due to the active pathological process with demyelinating and axonal damage to the CNS lead to the formation of neurological(More)
BACKGROUND Déjà vu (DV, from French déjà vu - "already seen") is an aberration of psychic activity associated with transitory erroneous perception of novel circumstances, objects, or people as already known. OBJECTIVE This study aimed to record the EEG pattern of déjà vu. METHODS The subjects participated in a survey concerning déjà vu characteristics(More)
The focal delta-waves and the remote influences of the stroke in the form of the sinusoidal flashes of delta-waves with a maximal amplitude exceeding an amplitude of the focal delta-waves (frontal flashes--FF) in frontal-polar leads were investigated in 51 patients (22 men, 29 women) by means of mapping, dipole location (BrainLoc) and LORETA methods. The(More)
Déjà vu (DV) – is an aberration of mental activity associated with the perception of surrounding reality with the impression that unknown objects, new contexts, and people seen for the first time are for some moments perceived as familiar. The aim of the present work was to study the EEG characteristics of the DV phenomenon in epilepsy. A total of 166(More)
An aim of the study was to investigate indices of autonomous regulation (evoked skin sympathetic potentials--ESSP) and EEG in temporal and frontal epilepsy (TE and FE) before and after functional tests (physical, psychoemotional, hyperventilation). The study included 24 patients with TE, 20 patients with FE and 20 healthy controls. The enhance of(More)
Panic disorders (PD) which develop in the context of different psychiatric diseases (neurotic, personality disorder and schizotypal disorders) have their own clinical and neurophysiological features. The results of compressive-spectral analysis of EEG (CSA EEG) in patients with panic attack were different depending on the specifics of initial psychiatric(More)
