Video EEG monitoring is a recently developed new type of EEG screening tool that can combine the clinical manifestations of a patient’s seizure with simultaneous changes in EEG activity, and obtain a video recording of the patient’s clinical manifestations at the same time as the EEG recording. With the development of technology, the video EEG monitor has a movable EEG and computer-aided EEG recording and analysis, which can be monitored at any time interval, while the monitor can record many physiological parameters including ECG, blood pressure, heart rate, electrooculogram, electromyogram and respiratory function, which is conducive to comprehensive analysis and evaluation. Compared with conventional EEG and dynamic EEG, the superiority of video EEG is: 1. This helps doctors to determine the relationship between abnormal waveforms and patients’ clinical performance, such as certain action artifacts, and reduce the occurrence of misdiagnosis and underdiagnosis. In conclusion, video EEG monitoring is important for diagnosis and differential diagnosis of epilepsy patients, classification of seizure types, localization of epileptic foci, assessment of seizure frequency and risk factors, and determination of efficacy and prognosis.
