“…There are studies demonstrating the relationship between cognitive decline (executive function, praxis, language, attention and memory) and prolongation of P300 latency in the central midline and left central brain parts in hypertensive elderly individuals in the acute period after ischemic stroke (up to 4 weeks) [19]. It is believed that in the later recovery period after antihypertensive and neurometabolic treatment, vascular brain disorders (cerebral microangiopathies), especially in the periventricular white matter of the posterior parts of the left frontal lobe, the middle part of the right cingulate gyrus and the posterior-medial part of the cerebellar body, persist in those with VS/E cognitive impairment [20].…”

The neurophysiological correlates of certain types of cognitive impairment in relation to the spatial pattern of auditory cognitive evoked-related potentials (ERPs) in hypertensive persons remain unclear. The aim of this study was to determine the parameters of ERPs (N200, P300) in impaired different domains (visuospatial/executive and memory) of cognitive function in arterial hypertension, including cardiovascular ischemic events. A total of 46 patients (65–84 years) were observed. The clinical diagnosis of vascular dementia, the Montreal Cognitive Assessment Scale (MoCA test) and the spatial pattern of ERPs (N200, P300) were the parameters used to identify three groups: the Control Group without cognitive impairment (n = 13), the group with a leading memory disturbance (Memory Group, n = 20) and the group with a leading visuospatial/executive disturbance (VS/E Group, n = 13). In persons belonging to the Memory Group, N2 latency was prolonged in the central (C3 C4) and right parietal (P4) brain parts; latency of the motor component (P300) may remain similar to that of the ControlGroup. In persons belonging to theVS/E Group, maximal prolonged recognition time (N2), especially in the left central (C3), frontal-midline (Fz), right parietal (P3) and temporal (P4) brain parts, was observed; P300 latency in the central-midline (Cz) and left anterior-temporal (F7) brain parts among all the groups was revealed.
