    Opis:
    The aim of the present study was to assess the propensity for risk taking among patients with obstructive sleep apnoea syndrome by means of a single-outcome gambling task that involved actual monetary losses and gains. We recruited 23 patients and 17 controls matched for sex, age and education. To explore the influence of previous outcomes on risky behaviour, we calculated the proportion of risky choices following sequences of one, two or three consecutive gains or losses. Patients with OSAS made significantly more risky choices than the controls. However, like the controls, they made more risky choices after two and three losses than after one, and fewer risky choices after two and three gains than after one. Their level of impulsivity did not differ from that of the controls. Our results show that OSAS induces a shift towards risk preference, but the ability to fully monitor and control ongoing behaviour remains intact.

    Opis:
    Background: Procrastination means delaying action, which creates serious problems both in academic, work, and clinical settings since it leads to reduced performance levels, and gives rise to psychological distress resulting in lower levels of health and well-being. Therefore, it is imperative to acquire a better know ledge of its reasons and relationships with psychological factors. Yet, the nature of those rela tionships remains am biguous. One of reasons is that many fac tors considered as causes of procrastination work as mediators, modify ing the relationships of procrastination with other factors. Hence, the present study aimed at delineating the factors, which might have a mediating effect upon the interface of procrastination with personality features. Material/Methods: Undergraduate students (n=62) participated in the study. The participation was voluntary and anonymous. A self-constructed Questionnaire of Predictors of Procrastination (QPP), a Polish version of the NEO-FFI test, and a Polish adaptation of the Pure Procrastination Scale (PPS) were administered, and there was no time limit. Results: Positive significant correlations between neurotism and general, decisive, and behavioral procrastination were found. There was also a significant interaction of neuroticism with the fear of failure, evaluation anxiety, low motivation and a lack of persistence as well as a lack of time management. In addition, the tendency to succumb to temptations and distractibility proved to be significantly related with procrastination, which suggests a lack of self-control. Conclusions: The current study confirmed observations that a neurotic personality does not determine procrastination but both those variables do interact. This study also shows that anxiety plays a significant role in starting actions and/or in accomplishing it. This is not only a fear of final evaluation, but the fear following the belief of impossibility to properly deal with a given action. Moreover, a capability of controlling emotions is closely connected with self-control enabling the planning, and organizing of an action, which is one of the main problems of procrastinators.

    Opis:
    The aim of this study was to test the hypothesis of developing Post-Traumatic Stress Disorder (PTSD) in a major right-hemisphere ischemic brain stroke survivor half a year after CEA revascularization, with the use of Event Related Potentials (ERPs). He was in a serious condition and had limited consciousness. Therefore, the doctor informed the patient's wife about the possibility of sudden death. The patient heard this information and remembered it, which was one of the main causes of the development of PTSD. On the basis of previous research amplitudes of P3 ERP, components elicited in the cued GO/NOGO tasks have been chosen as the candidate for PTSD neuromarkers . A 44-year-old patient had a major ischemic brain stroke while sizeable atherosclerotic plaque causing critical stenosis of the internal carotid artery in Angio-CT was dioscovered. The patient was urgently operated on using CEA. After the operation he had the opportunity to see the removed plaque which had been the cause of his stroke. Despite the positive postoperative recovery, half a year later, the patient began to complain of flashbacks, anxiety, trouble in falling and staying asleep, difficulty in concentration, a loss of interest. For the diagnosis of PTSD we used Checklist Specific for a stressor (PCL-S). Additionally we used Checklist according to the Diagnostic Statistical Manual-5 (DSM-5) classification, and the patient met the PTSD criteria. The cognitive profile of the patient was measured with the use of the Wechsler Memory Test – III (WMS-III). Subsequently, the patient participated in the cued GO/NOGO task (Kropotov, 2009) with a recording 19-channel EEG. The P3 GO and NOGO waves in this task were found to be significantly smaller at p

    Opis:
    The sudden loss of mobility is always an extremely difficult situation, since it entails many consequences. In the process of dealing with it, the individual’s predispositions play a significant role. Three predispositions seem to be crucial for maintaining emotional balance, accepting the existing health situation and coping with challenges: dispositional optimism, a sense of self-efficacy and psychological resilience. The aim of our study was to compare the levels of these individual predispositions and dimensions that affected the ability of the study group to cope with the sudden loss of mobility as a result of a traffic accident, and to determine the relationships between them. The study group consisted of 72 adults (36 women and 36 men), who suffered from full paralysis of the lower limbs due to spinal cord injury caused by a traffic accident. The research tools used were the GSES Scale, the LOT-R Test, the SPP-25 N Scale, the Beck Depression Scale, the AIS Scale and the CISS Questionnaire. The women in our study exhibited lower levels of all three of the selected predispositions. They also present more severe symptoms of depression and a lower acceptance of the loss of mobility. When facing stressful situations, they prefer the emotion-oriented style and, less frequently, the avoidant style, and they reveal a lower tendency to choose the task-oriented response. Dispositional optimism, self-efficacy and resilience positively correlate with acceptance of the disability and the use of a task-oriented style to cope with stress. However, they correlate negatively with the severity of depressive symptoms and a style focused on emotions. Gender is a moderator of relationships between the studied parameters.

    Opis:
    The aim of our research was to evaluate the effectiveness of neurofeedback in reducing the symptoms of chronic Post Traumatic Stress Disorder (PTSD) in a patient who had developed the syndrome following a recurrence of sphenoid wing meningioma (SOM). EEG spectra and event-related potentials (ERPs) were used to construct an individual neurofeedback protocol and to provide objective monitoring of treatment efficacy. The patient, a 34-year-old female, was diagnosed with a sphenoid wing meningioma (SOM), which had been successfully operated. Three years later, however, the SOM had overgrown at the optic foramen and extended into the optic canal, and the patient had developed blurred vision. She was repeatedly operated, and recovered well. However, due to the recurrence she developed flashbacks, anxiety and sleep difficulties, such that she was unable to continue working in her profession. The symptoms had been occurring for 4 months. ERPs in a cued NOGO task, along with EEG spectra in the resting state and during task performance were used to assess brain functioning, providing the basis for a neurofeedback protocol. Twenty sessions of individually tailored neurofeedback were performed. The patient experienced a reduction of symptoms, accompanied by normalization of ERPs parameters. The results obtained in this case point to the possible benefits of individually tailored neurofeedback protocols in the treatment of PTSD.

    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.
