Abstract

Aim: The aim of this study was to assess if pre- and post- event related potentials (ERPs) components after visual stimulation training admitted differences exist in subacute stroke patients and to observe the outcome markers of cognitive functions recovery by using Neurowave system. Materials and Methods: Eighteen ischemic subacute stroke patients were enrolled and underwent to neuropsychological evaluation and ERPs recording at two time points, at baseline (T0) and after 3 months from (T1). All patients were stimulated with customized images for three days a week. Findings: Intra group analysis showed a significance difference in ERPs parameters and neuropsychological tests. Correlation analysis showed a significant relation between neuropsychological and ERP values. Conclusion: Our findings confirm that P300 ERPs’ component could be a predictive marker for cognitive recovery of ischemic subacute stroke patients. Intensive programs of neurosensory stimulation could facilitate recovery of cognitive and attentive functions in subacute cerebrovascular disease.
