COMPARATIVE ANALYSIS OF EEG COHERENCES IN COGNITIVE DISORDERS IN PATIENTS WITH VASCULAR DEMENTIA
As a result of the conducted research, the analysis of coherent connections in the alpha range revealed a weakening of interhemispheric coherence and an increase in intrahemispheric coherence, mainly of the right hemisphere. The data obtained indicate in favor of violations of the transfer of information from the right hemisphere to the left and the strengthening of the activity of the right brain with the formation of a holistic thinking strategy to the detriment of the analytical strategy. Disorders of cognitive functions due to changes in interhemispheric and intrahemispheric integrations were noted in patients with vascular dementia in the domains of consciousness, perception, concentration, memory and speech function. The data obtained make it possible to use coherent EEG analysis to objectify cognitive impairments in patients with vascular dementia, including dynamic observation.
