Neurophysiological features in patients with psychopathological disorders in the right hemisphere stroke

Abstract

Neurophysiological changes and functional activity of the brain on the electroencephalogram after a cerebral infarction reflect the direct electromagnetic activity of neurons that can be measured in the affected areas of the brain. EEG signals provide a non-invasive and sensitive indicator of brain function during mental processes. Its main use is in the assessment of cerebral function, and not in the detection of structural abnormalities. There is a lot of evidence that the analysis of the electrical fields of the brain can detect changes in the behavior of brain signals in neurological patients. The aim of the study was to establish correlational relationships between the development of psychopathological disorders and neurophysiological changes using EEG in right hemisphere stroke. The subject of the study was neglect and its relationship with neurophysiological changes and functional activity of the brain. Twenty-three patients with a right-hemisphere stroke who were undergoing inpatient treatment in the medical and diagnostic department No. 1 of the LORITOM PE. The correlation of the reduced α-index in patients with manifestations of unilateral neglect on the background curve was determined in the cohort of subjects. Moderate irritation phenomena was noted closer to the center in the parietal and to the right in the temporal and parietal leads in patients with neglect syndrome. While without manifestations of hemineglect, moderate phenomena of irritation was noted mainly parasagittal and on the left. A trend of slow-wave activity in the frontal areas in patients with neglect syndrome has been demonstrated. The prospect of further research in the field of psychopathological disorders is shown which will significantly increase the efficiency of diagnosis and treatment and as a result increase the degree of restoration of impaired functions of post-stroke patients, the level of their social and everyday adaptation and accordingly the quality of life. Keywords: electroencephalography, unilateral neglect, hemineglect.
