Impact of Hypertension on Cognitive Function in Middle Age in the European North of Russia
BACKGROUND: Hypertension is a known risk factor for adverse cognitive outcomes. The age at which it begins to affect cognitive function remains unclear. AIM: The work aimed to investigate the impact of elevated blood pressure on cognitive function in middle-aged adults by assessing the auditory P300 event-related potential. METHODS: This study included residents of Arkhangelsk aged 45–59 years with hypertension (n = 102) and without hypertension …
A study of cognitive functions in elderly men from the Arctic region of the Russian Federation with arterial hypertension using the auditory event-related potentials P300
AIM: To study the effect of arterial hypertension on cognitive functions by evaluating the auditory event-related potentials (ERP) Р300 in men aged 60-74 years from the Arctic region of the Russian Federation with the special emphasis on men receiving antihypertensive therapy with controlled arterial hypertension and those who either do not take antihypertensive drugs or take them both regularly and irregularly without controlling blood pressure.…
Association of hyperuricemia and type 2 diabetes mellitus with cognitive functions assessed using the event-related P300 potential in older individuals with controlled arterial hypertension
BACKGROUND: The number of individuals with dementia and cognitive impairment is steadily increasing worldwide. Identifying and controlling risk factors for cognitive decline is crucial for preserving cognitive function.AIM: To assess the association of hyperuricemia and type 2 diabetes mellitus (T2DM) with cognitive functions, evaluated using parameters of the auditory event-related P300 potential in elderly individuals with controlled arterial h…
Parameters of the P300 auditory evoked potential and autonomic heart rate regulation in adolescents residing in different climatic and geographical conditions of Russia
BACKGROUND: The physiological functions and body development take place as the body adapts to the environment. For schoolchildren aged 16-17, their primary focus is on studying, which involves processing and retaining a significant volume of diverse information. The P300 auditory evoked potential reflects the neurophysiological aspects of cognitive functions such as attention and memory. This assessment is particularly relevant when considering t…
Features of components N2 and P300 of auditory evoked potential dependent on the level of internet addiction in adolescents
INTRODUCTION: Due to the popularization of digital technologies, people have begun to spend more time on the internet. Existing studies show mixed results about the impact of internet use on attention, cognitive control, and other cognitive functions.AIM: To evaluate the components of the event-related potentials (ERPs) P300 and N2 in practically healthy adolescents aged 1617 years with varying levels of internet addiction risk and a stable patte…
Changes in cardiovascular indices and bioelectric activity of the brain in response to cold exposure in young men
The aim was to study changes in cardiovascular indices and electroencephalogram (EEG) characteristics in response to short-term general air cooling of the body in young adults. Methods. The sample consisted of 13 healthy men aged 18-21 years who were permanent residents of the city of Arkhangelsk (Northwest Russia). The spectral power (SP) of EEG rhythms was assessed using an electroencephalograph (Neurosoft, Russia). Heart rate variability (HRV)…
Features of Auditory Cognitive Evoked Potentials P300 in Successful Heart Rate Variability Biofeedback in Adolescents Living in Arctic Area
The purpose of the investigation was to evaluate the auditory cognitive evoked potentials P300 parameters before and after vagal influences on the heart rhythm activation with biofeedback control in adolescents aged 15-17 years in the Arctic-Polar region (64°30' N) and the Subpolar region (67°30' N). There have been identified different variants of the P300 latency change, reflecting the neurons integration in the functional systems to ensure and…

The character of the electroencephalogram (EEG) changes during a once procedure of heart rate variability biofeedback was considered in adolescents 14-17 years with different autonomic nervous types living in the different geographical latitudes and climatic, ecological conditions of the European North: the Subpolar (64°30' N) and Polar (67°40' N) areas. More intensive reduction of theta EEG activity (p < 0,05-0,001) with a predominance of the dy…
Age Features of Cardiovascular System Functional Parameters in Adolescents Living in Different Arctic Areas
Age features of autonomic nervous regulation of cardiac activity in 426 healthy adolescents aged 14-17 years living in areas of different latitudes, climatic and ecological conditions of the European North - in the Subpolar (64°30' N) and Polar (67°40' N) areas have been detected. Assessment of the cardiovascular system status was carried out with the use of the heart rate variability (HRV) and blood pressure (BP) parameters. The share of persons…
Alterations of Dynamics of Human Electroencephalogram Spectral Parameters During Daily Geomagnetic Field Variations
The technique of identifying the nature of daily changes in spectral power relations of the basic rhythm brain activity and geomagnetic field variations has been proposed. There has been carried out an analysis of electroencephalogram (EEG) alpha activity spectral power recording at every minute in the morning, afternoon and evening during 5 days (12 recordings, 30 minutes each) in three healthy volunteers compared to every-minute variations of t…
Variants of Eeg-Reactions During HRV Biofeedback Course in Adolescents With Different Initial Autonomic Nervous Tone
There was surveyed a character of brain bioelectric activity change during carrying out of biofeedback sessions by heart rate variability parameters (HRV biofeedback) in adolescents aged 15-17 years with different initial autonomic nervous tone. It has been established, that adolescents with the optimal autonomic nervous tone have high reactance of both autonomic nervous system parts. At the end of HRV biofeedback course there is more significant…
