    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:
    New neurotechnologies which help to study not only the structure but also brain work, especially in milliseconds, allow for a more accurate diagnosis of a given disease entity. The aim of our study was to characterize the functional neuromarkers, including a new neuromarker, that is high rolandic beta, in Parkinson’s disease (PD). A 76-year-old male patient, a university professor, a widower, in an intimate relationship with a beloved partner, was tested in the Reintegration and Training Center of the Polish Society of Neuropsychology. Five years earlier (when he was 71 years old), following long-term stress, he had had a transient ischemic attack (TIA). In the following years he experienced two neurological episodes, and was diagnosed, on the basis of MRI findings and clinical symptoms, with vascular (multi-infarct) Parkinsonism. A sudden deterioration in his functioning, including hand tremors at rest, bradykinesia (motor slowdown), asymmetrical gait difficulties, postural instability, and falls typical for PD, as well as MRI finding (the appearance of ‘a swallow tail ’ on the left side, and the lack on the right of the substantia nigra within the midbrain) was the cause of further differential diagnosis. He was assessed using the HBI methodology (Kropotov 2016; Pąchalska, Kaczmarek, Kropotov 2014). EEG was recorded from 19 scalp sites, in resting state conditions, with eyes open and eyes closed, and during the cued GO/NOGO tasks with animal/plants as GO/NOGO stimuli. The electrodes were applied according to the International 10-20 system. The EEG was recorded referentially to linked ears, allowing for a computational re-referencing of the data (remontaging). Event related potentials (ERPs) were used to assess the functional changes manifested by the patient. To compare our patient with healthy controls we used the normative Human Brain Index (HBI), a database obtained through joint research by Swiss, Norwegian, Polish and Russian neuroscientists (Kropotov 2018). This database included behavioral parameters and ERP measures in 6 different neuropsychological tasks for 1000 healthy subjects. What is striking, no signs of cognitive dysfunction was found; however observed were an asymmetrical frontal lobe alpha (a neuromarker of depression) and excessive Rolandic beta (a neuromarker of Parkinson’s disease). We will discuss the results on the basis of recent subject literature findings, including the personal factors that might influenced the process of the diagnosis and treatment of this patient, ones which should be also taken into account in any differential diagnosis. The obtained results show the importance of using HBI methodology in clinical practice. Physicians involved in the diagnosis and treatment of those with progressive ambulatory impairment and an abnormal white matter (WM) signal on neuroimaging, should when formulating any differential diagnosis consider the use of this approach. ------------------------------------------------------------------------------------------------------------------------------------

    Opis:
    Objective. The study aimed to evaluate the application of ERPs neuromarkers for the assessment and treatment of a patient with chronic crossed aphasia after severe TBI and a long-term coma. Case report. An ambidextrous female patient, aged 29, suffered from posttraumatic chronic crossed aphasia, severe TBI and a prolonged coma after a car accident. The patient took part in two differentiated rehabilitation programmes of neurotherapy included 20 sessions of relative beta training and 20 sessions of rTMS; both programmes were combined with behavioural training. The patient was tested 3 times: before the experiment, after completion of programme A, and after completion of programme B. Results. In the 1st recording, the neuromarker of aphasia was found – an excess of the P2 wave over the left temporal area. There was a cognitive control deficit – an excess of omission errors and an increase of RT variability – all indexes of sporadic ADHD. In the 2nd recording, slight improvements in cognitive control, and language functions were found. In the 3rd recording, after the rTMS sessions most of her cognitive dysfunctions had been resolved, including language functions. It should be stressed that the activation (especially the increase in the ERP potential of the right side over the frontal lobe) was found. The neuromarker of aphasia did not change, only the location had slightly moved frontally. Conclusions. The application of ERP neuromarkers assists in the diagnosis, treatment, and academic success of an ambidextrous patient with chronic posttraumatic aphasia and sporadic ADHD. ERPs can be used to assess the functional brain changes induced by neurotherapeutical programmes.
