Initial Comparison of Routine Electroencephalography and Event-Related Potentials in Patients with Cognitive Complaints

Routine electroencephalograms (EEGs) assess brain function, but can be time-consuming, resource-intensive and setting-restrictive. Brain vital signs (BVS) evaluation, derived from EEG-based event-related potentials (ERPs), offers a rapid, standardized evaluation of cognitive function. In this study, 20 outpatients with cognitive complaints underwent both routine EEGs and BVS evaluation. While only 4 participants showed abnormal EEG results, 11 had at least one of the six BVS out-of-range, suggesting increased sensitivity to cognitive impairment. This commentary discusses the feasibility and potential value of standardized BVS evaluation as a simple objective method for cognitive function evaluation.
