    Opis:
    Objective. The aim of the study was to find a neuromarker of perioperative anxiety in a patient with critical carotid stenosis through the use of neuromarkers in Quantitative EEG (QEEG) and Event Related Potentials (ERPs). The indirect purpose of the research was evaluation of improvement in the patient’s quality of life. Case study. A 45-year-old woman was admitted to the Department of Vascular Surgery and Endovascular Interventions at the John Paul II Hospital in Krakow, with the diagnosis of critical internal carotid stenosis (over 80%), confirmed by Doppler Ultrasound and Angio-CT examinations. Before hospitalization, the patient had not presented any symptoms of brain ischemia. It was found that severe anxiety on the Hospital Anxiety and Depression Scale (HAD) was worse before the surgery. After the operation, a reduction anxiety in occurred as well as an improvement in the majority of the dimensions of health. Therefore, her quality of life improved. Conclusions. Significant changes were observed on the Hospital Anxiety and Depression Scale (HAD). Modern neurotechnologies measures are necessary to capture all the changes in the symptoms of anxiety before and after the operation for a carotid stenosis. ERPs might be used to select patients with neuromarker of perioperative anxiety, and subsequently to serve in proper psychological care and minimalize the perioperative risk of complications.

    Opis:
    When the energy within the mass of the human brain that is associated with the intrinsic range in fluctuations of the Gravitational Constant (G) is set equal to the energy from a magnetic field (B) within the cerebral volume and solved for B, a value in the order of 20 to 50 nT is obtained. Quantitative Electroencephalographic (QEEG) and sLORETA (Low Resolution Electromagnetic Tomography) analyses of cerebral cortical activity during exposure to a range of applied rotating, frequency-modulated, transcerebral (between the two temporal lobes) magnetic fields between < 1 nT and 7000 nT while volunteers sat within a darkened, quiet chamber were completed. There was marked enhancement of power within the 4 Hz to 10 Hz band within the right caudal (cuneus) hemisphere while the ~5 to 20 nT averaged strength magnetic fields were applied but no significant responses at lesser or greater intensities. These results suggest that a physical process coupled to the source of the fluctuation (~10-15 m3kg-1s-2) in G may interact with right hemispheric activity within the range at which gravity waves have been estimated to interact with Schumann frequencies generated between the earth and ionosphere.

    Opis:
    Brain central fatigue has been hypothesized as a factor affecting sports performance that generally occurs after a competition. Therefore, the aim of this study was to observe brain activities after participating in a competition. This study used quantitative electroencephalography (QEEG) to evaluate brain central fatigue, and the results were analyzed in terms of brain connectivity (coherence) in the delta frequency bands. QEEGs were recorded from twenty-nine Thai professional female soccer players (mean age ± SD was 24.17 ± 2.633 years, mean height ± SD was 1.620 ± 5.552 meters, mean weight ± SD was 55.10 ± 5.853 kg). We recorded QEEG three times: twice before a competition (once a week) and one week after the competition. Data obtained were analyzed by using the Z-scored FFT method. The results of brain connectivity were represented in terms of coherence. The present study revealed brain central fatigue in athletes after the competition (p=.035 and p=.003). This condition could affect their performance during games. Moreover, the key players showed specific brain patterns that were significantly different from substitute players (p<.000). The brain commonly returns to a normal state after a competition. This phenomenon was observed in the substitute players. Contrastingly, key players (on the ground players) exhibited the brain central fatigue phenomenon. Our study confirmed that brain central fatigue can arise after a competition, and specific brain patterns can identify the level of sports performance. These findings are beneficial for predicting athletes’ performances in terms of aspects of the brain. This approach can be used to measure and interpret brain central fatigue conditions.

    Opis:
    W artykule przedstawiono koncepcję oceny procesu poznawczego na podstawie planowanych badań elektroencefalograficznych QEEG. Głównym problemem badawczym jest próba odpowiedzi na pytanie, czy i w jakim stopniu wykorzystanie nowoczesnych programów symulacyjnych stosowanych w kształceniu zawodowym wpływa na efektywność kształcenia. Efektywność kształcenia jest pochodną aktywności procesu poznawczego podczas uczenia się. W celu odpowiedzi na ten problem planuje się analizę aktywności mózgu dzięki rejestracji i obserwacji przebiegu róż-nych fal oraz wielkości potencjałów generowanych przez układ nerwowy.
    The article presents the concept of assessment of the cognitive process based on planned QEEG encephalography. One of the stages of the planned research is to determine the research problem and any variables. The main research problem is, therefore, the attempt to answer the question whether and to what extent the use of modern simulation programs used in vocational education affect the effectiveness of teaching? The effectiveness of teaching is a derivative of the activity of the cognitive process during learning. In order to answer this problem, it is planned to analyze brain activity by recording and observing the course of various waves and the magnitudes of potentials generated by the nervous system.

    Opis:
    Health related quality of life (HRQoL) is the most desired patient centered outcome of medical care (Leplége et al. 1997). In patients with long term illness, such as Hypertrophic Pachymeningitis (HP) still under diagnosis, therefore no possible to properly cure, it might be the only outcome achievable (Netuveli et al. 2005; Trystuła 2017). The problem becomes even more serious when occurs in young person: starting a family and caring for children becomes hard or even impossible, because of his/her physical and psychical conditions. Most clinicians are aware of the importance for quality of life of this functional limitation, but there are no articles describing this problem in the literature. We aimed to fill this gap in knowledge. 29 year old patient, a car mechanic, married, with 4-year-old son, with the long his- tory of the illnes, and especially persistent, diffuse, non-specific headaches, frequent seizures and cognitive deterioration which have been particularly troublesome recently. He was finalny diagnosed with Hypertrophic Pachymeningitis (HP) associated with Immunoglobulin G4-related (IgG4) with the use of specific diagnostic criteria for HP associated with IgG4-RD (IgG4-HP), which rely on histopathologic analysis (Lindstrom et al. 2010; Lu et al 2014). Computed tomography (CT) of the head showed massive calcifications visible along the cerebellar tentorium on the right side, along the cerebral falx, as well as on dura mater on the cranial vault of both cerebral hemispheres. The patient was diagnosed with common variable immunodeficiency (D 83), thrombocytopenia, chronic EBV hepatitis and epilepsy. IgG4-HP was confirmed by CT, MRI and biopsy (IGg4-RHP antibody was detected). The treatment with steroids, and immunosuppressive therapy (RTX) was introduced (as it was suggested by Levraut et al. (2019). It should be stressed that he had a significantly reduced health-related quality of life (HRQoL), mainly because of long-lasting illness, diverse symptoms, often hospitalization, complex differential diagnosis, and especially biopsy which requires neurosurgical intervention, which affect his physical and mental well-being, especially cognitive control, and not possibility to take care of his family. To help the patient we introduce HBI methodology (Kropotov 2016), that is an evaluation of working brain in milliseconds. Quantitative electroencephalography (qEEG), event-related potentials (ERPs) and low-resolution sLORETA tomography were performed. We did not found any paroxysm of 3 Hz rhythm in Eyes Closed (EO) and in Eyes Open (EO) conditions, however the ERPs deviations from the reference indicate deficit of cognitive control (decrease of P3 NOGO wave in comparison to 100 persons from the normative data base from the Human Brain Index in Chur, Switzerland). Therefore, the patient was offered Transcranial Direct Current Stimulation (atDCS) combined with goal-oriented psychotherapy program. It was found that after 40 days of therapy, cognitive control returned, which was translated into a better quality of life related to the patient's health, measure in the 36-Item Short Form Survey (SF-36). The patient returned to his previous job as a head of car mechanic service. Final diagnosis of IgG4-HP and subsequently, proper farmacotherapy, and introduction of HBI methodology allowing for the selection of an adequate method of neurotherapy, for our patient the transcranial direct current stimulation (atDCS) combined with goal- oriented psychotherapy, was helpful in the improvement of his quality of life.

    Opis:
    Early diagnosis and monitoring of disease progression in patients with Vascular Dementia (VaD) have become vital in clinical practice, as disease modifying treatments for VaD become available. The goal of our research was to study cognitive impairment in a patient at an early stage of VaD. We evaluated latencies of the P3 GO and NOGO components of event-related potentials (ERPs), elicited in cued GO/NOGO tasks, as potential neuromarkers of cognitive im- pairment, as suggested by previous research. The patient, a right-handed, 53-year-old male with a college edu- cation, suffered a transient ischemic attack (TIA) in 2011. During this attack, which lasted for a few minutes, he was confused and had trouble speaking, trouble seeing in both eyes, difficulty walking, problems with balance and coordination, and strange behavior. Se - ven years later, in 2018, he was assessed using the HBI methodol- ogy, which consisted of recording (1) a 19-channel EEG in resting state (with eyes open and eyes closed), and (2) a cued GO/NOGO task, and then comparing the results with EEG spectra and Event- Related Potentials (ERPs) data from normative and patient data - bases. The patient died in 2019. Post-mortem studies confirmed cortical microhaemorrhages neuropathological criteria for VaD. We did not found deposits of hyperphosphorylated tau (HPτ) and Aβ, which fulfil the neuropathological criteria for AD. The parietal-temporal-occipital EEG power was significantly higher in all conditions in this subject in comparison to healthy controls, indicating idling of the corresponding areas. The amplitude and la- tency of the P3 GO wave were found to be intact in the subject, in- dicating normal posterior cortical functioning in the cognitive task. The latency of the P3 GO wave was found to be significantly higher in the subject, indicating impairment of engagement operations. In a GO/NOGO task, ERPs provide a useful tool for assessment of brain functioning in clinical settings.

    Opis:
    Simulation programs in polytechnic (vocational) education have an important didactic function. On the one hand, they are a great example of modern didactic software, on the other hand, knowledge of the simulation software environment by a future graduate of a technical university increases the qualifications of the future employee and allows him to acquire an attractive profession. In the era of high requirements set by employers and competition on the education market, their knowledge seems highly justified. However, whether simulation programs, especially deterministic ones, can also act as teaching aids is not so obvious. In this article, in addition to purely theoretical considerations, will be presented stages of own research on didactic efficiency, or more precisely the impact of this group of software on the cognitive process during learning. More importantly, the didactic effectiveness was tested based on typical pedagogical research as well as by means of electroencephalographic tests using the QEEG method.

    Opis:
    Melatonin and cortisol are the main hormones of the circadian rhythm, which effect cognitive decline during aging. An imbalance of circadian rhythm hormones serves as an early sign of the progress of age-related disease and brain pathology in aging. The aim of this study was to determine the cortisol-melatonin ratio in relation to brain activity and cognitive function in aging. Sixty-four aging subjects were recruited from the brain healthy project. The morning salivary of all subjects was collected for cortisol and melatonin levels analysis. The brain activity was recorded for 5 minutes in the eyes open condition and seven cognitive functions were assessed by the MoCA. The results were divided into a low ratio group and a high ratio group of cortisol-melatonin ratio. The low ratio group and the high ratio group differed in the delta-beta ratio at the left temporal lope (p < .05), and the delayed recall in the high ratio group was markedly higher than in the low ratio group. Moreover, the cortisol-melatonin ratio was strongly correlated with delayed recall (p < .05), the delta-beta ratio in the left temporal lope (p <.05), the theta alpha ratio in the left temporal lope (p < .05), and right temporal lope (p < .05). We found that a low cortisol-melatonin ratio corresponded to a high delta-beta ratio and a high thetaalpha ratio at the left temporal lobe with a low score of delayed recall function, but a high cortisol-melatonin ratio corresponded to a low delta-beta ratio and a low theta-alpha ratio at the left temporal lobe with a high score of delayed recall. The imbalance of the circadian hormone related to cognitive function and brain activity in aging could serve as a biomarker of age-related diseases.

The patient was a 25-year-old male, diagnosed with ASD. He never developed spoken language, and communicated only by gesturing or writing on a computer. Our findings confirmed comorbidity of ASD and epilepsy, accompanied by dysfunction of cognitive control. We also found that spontaneous EEG and event-related potentials (ERPs) in a cued GO/NOGO task can be used to assess functional brain changes concomitant with ASD.

    Opis:
    Cortisol is known to be correlated with cognition, aging, and quantitative electroencephalography (QEEG), although these factors have not yet been reported. This study aimed to evaluate an integrated model for estimating cortisol levels in elderly people. Sixty-four participants were included. Saliva cortisol levels were measured by enzyme-linked immunosorbent assay (ELISA). Cognitive function was assessed by the Montreal Cognitive Assessment (MoCA). EEG recording was performed during the eyes-opened resting state condition. QEEG in five frequency bands and ten ratios were analyzed. Stepwise multiple linear regression was used to estimate cortisol levels based on the QEEG index, age and cognitive function. The first model using the QEEG index estimated cortisol levels with an accuracy of 15.4%. The second model based on the QEEG index and age estimated cortisol levels with an accuracy of 24.3%. The third model based on the QEEG index and cognitive impairment estimated cortisol levels with an accuracy of 20.2%. The fourth model yielded the best results, estimating cortisol levels with an accuracy of 30.8%; this model was based on age, delayed recall and the QEEG index of the beta/high beta band at the central region and the delta/beta band at the left temporal region An integrated model of the QEEG index, age and delayed recall can be used to estimate cortisol levels in elderly people, which could be possibly used to predict physiological and psychiatric changes in humans.

    Opis:
    The goal of the present study was to investigate the effect of competition on brain activity representing aggression. Quantitative electroencephalograms (QEEGs) of Thai professional female soccer team players were analyzed in terms of aggression. The QEEGs of 17 soccer players were recorded three times: twice before a competition (once per week) and one week after the competition. There was a significant increase in the beta frequency band associated with the Fp1, Fp2, F7, and F8 positions as the competition approached. The changes in brain activity were observed in two patterns: the first was an increase in the intensity level of brain processing (presented in terms of brain topographic maps as absolute power), and the second was the magnitude of the amplitude at each of the EEG channels between the hemispheres (presented in terms of brain connectivity as amplitude asymmetry). Consequently, QEEG values were examined as they related to aggression. In the statistical analysis, paired-sample t tests confirmed that an aggressive phenomenon occurred as the competition approached. In addition, the aggressive phenomenon was found in the brain activity of players with defensive soccer positions.
