[Impact of COVID-19 on some neurological and psychological features in epilepsy].

The new coronavirus infection spread around the world in a very short time and turned into a pandemic with a wave-like flow for more than two years. COVID-19infection affects selectively various organs and systems, including the nervous system; neurological manifestations have been reported, including anosmia, encephalopathy, stroke, epileptogenic disorders, which necessitates studies of the course of brain diseases, among which epilepsy occupies a significant place.

[Clinical and neurophysiological parameters in patients with epilepsy in the long-term period after COVID-19].

Objective: Clinical and psychophysiological assessment of the dynamics of the condition of patients with epilepsy in 4-6 months after the coronavirus infection.

Material And Methods: An open controlled prospective comparative outpatient clinical and physiological study of patients diagnosed with epilepsy after suffering from COVID-19 (after 4-6 months) of moderate severity (=16), patients diagnosed with epilepsy who did not suffer from COVID-19 (=7), a control group (=11) after confirmed COVID-19 (after 4-6 months). All groups were in the age range 23 to 50 years.

[Neurophysiological and functional neuroimaging methods in the assessment of migraines and epilepsy with vertigo].

A review of the current literature shows that the combined use of neurophysiological and structural-functional neuroimaging methods has significantly expanded the understanding of the mechanisms of migraine with vestibular dysfunction: functional and structural disorders were found in brain regions involved in multisensory vestibular control and Central vestibular processing. Analysis of numerous studies shows that epilepsy can also cause vestibular symptoms, they can occur both without epileptic markers, and in combination with epileptic paroxysms. In isolated epileptic vertigo, according to studies widely presented in the literature, epileptic activity was most often detected by EEG data in the temporal regions, to a lesser extent in the parietal regions.

[Neurophysiological methods in the assessment of different forms of migraine].

The review considers the efficacy of neurophysiological methods for the study of migraine. According to many authors, such neurophysiological methods as analysis of visual and somatosensory evoked potentials, trigeminal evoked potentials are informative for assessing the functional state of trigeminocervical and sensory systems. Analysis of bioelectric activity of the brain is used for differential diagnosis of migraine and epilepsy, evaluation of various forms and types of migraine.

[Neurophysiological and clinico-biological features of internet addiction].

Aim: To analyse neurophysiological and some physiological characteristics of people with Internet addiction.

Material And Methods: Two groups of subjects were studied: with Internet-addiction lasted no more than two years and the control group. Spectral-correlation parameters of EEG, functional asymmetry of EEG parameters, and heart rate variability were recorded.
