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. ------------------------------------------------------------------------------------------------------------------------------------

HBI methodology
Opis:
The purpose of this study is to evaluate the effectiveness of functional neuromarker- based electroencephalographic training with neurofeedback (EEG-NFB) for a patient with dysexecutive syndrome following neurosurgical operation of two brain aneurysms of the left and right middle cerebral artery (MCA) detected after COVID-19 disease. A right-handed, 56-years-old, not vaccinated, patient, became infected with SARS- CoV-2 and contracted COVID-19 with the manifestation of respiratory symptoms, high fever, dyspnea and low saturation of 79% Sa02. She was hospitalized at the Infectious Disease Unit, where a positive RT PCR test for COVID-19 was confirmed. The acute phase of COVID-19, during which oxygen therapy was administered, lasted two weeks and was complicated by brain fog and transient hypertension (175/100). There were no signs of focal damage to the central nervous system. She was discharged home in a good general and neurological condition. After returning home, the patient was unable to cope with daily functioning, as she said her brain fog continued to persist, manifesting itself as executive dysfunction. Eight weeks after the infection, the patient's neuropsychiatric condition worsened. On CT and MRI examination of the cerebral vessels, she was diagnosed with the presence of two aneurysms located on the left and right middle cerebral arteries (MCA). She was operated on at the Department of Neurosurgery and Neurotraumatology, where a pterional craniotomy and clipping of both brain aneurysms was performed. The Yasargil titanium clip was placed on the aneurysm neck. During the surgery procedures, performed two months apart, there were no signs of a history of subarachnoid haemorrhage and the post-operative period was uneventful, except for a drooping right-eye eyelid (after the second surgery) with a tendency to improve. Each time, the patient was mobilized and walked independently and was discharged home in a good general condition, with no neurological symptoms, except for executive dysfunction. Approximately five months after the SARS-CoV-2 infection (four weeks after the second surgery), her executive dysfunction worsened. Neuropsychological testing using Mindstreams™ Interaction Computer Tests revealed moderate Dysexecutive Syndrome (DES), while neurophysiological testing using qEEGs, ERPs and sLORETA tomography, a functional neuromarker of frontotemporal area dysfunction. The EEG pattern was characterized by excessive, slow (about 6 Hz) activity in frontotemporal areas, which indicated the progressive loss of cognitive control over time. The patient was offered an electroencephalographic training protocol with neurofeedback (EEG-NFB) based on the detected functional neuromarker, which reduced DES. The improvement achieved during therapy was statistically significant [compared to the normative database (Human Brain Index, HBI)]. In effect, the patient's quality of life improved, as she herself pointed out. Her symptoms of brain fog and DES disappeared and she returned to her previous work as a waitress. The Human Brain Index (HBI) methodology can be successfully used in the neurodiagnosis and implementation of individualized electroencephalographic training with neurofeedback (EEG-NFT) for patients with executive dysfunction after contracting longCOVID.
