Event-related potentials (ERPs) are potential activities extracted from electroencephalogram (EEG) that are associated with specific stimuli. They possess the advantages of objectivity, ease of operation, and real-time reflection of cognitive processing in the brain. ERPs have been extensively utilized in studying pathophysiological mechanisms related to Alzheimer’s Disease (AD), Parkinson’s Disease (PD), stroke, schizophrenia, and other conditions. Epilepsy is a common neurological disorder wherein ERPs can be employed to explore the neuroelectrophysiological causes underlying cognitive impairment, anxiety, and depression in patients with epilepsy while providing an objective assessment. This article reviews the application of ERPs in patients with epilepsy.
