Video-Electroencephalography Monitoring in Epilepsy Management
Summary
Video‐electroencephalography monitoring combines continuous neurological recording with synchronised video capture to document seizure activity and associated behaviours. This technique is central to the diagnosis and classification of paroxysmal events, distinguishing epileptic from non-epileptic phenomena and localising seizure onset within the brain. Prolonged monitoring in dedicated epilepsy monitoring units facilitates systematic withdrawal of antiseizure medication to provoke habitual seizures, assess risk of seizure-related injuries and guide decisions on surgical candidacy. Recent advances have refined optimal recording durations, developed ambulatory systems for home-based monitoring and enhanced safety protocols to mitigate complications during inpatient admissions. By integrating real-time imaging, quantitative analysis of interictal discharges and automated detection algorithms, video-EEG monitoring continues to evolve towards more efficient, patient-centred workflows with global relevance across diverse health-care settings.

Video-Electroencephalography Monitoring in Epilepsy Management publication trend
The graph below shows the total number of articles in video-electroencephalography monitoring in epilepsy management across all publications each year (not limited to Nature Index journals).
Technical terms
Video-electroencephalography (video-EEG) monitoring: Concurrent recording of scalp EEG signals and synchronised video footage to capture and analyse seizure events.
Epilepsy monitoring unit (EMU): A specialised inpatient facility equipped for long-term video-EEG monitoring, medication tapering and safety supervision.
Interictal epileptiform discharge (IED): Transient EEG spike or sharp wave occurring between seizures, indicative of heightened epileptic brain activity.
Antiseizure medication (ASM): Pharmacological agents used to suppress seizures; managed withdrawal may be employed during monitoring to provoke typical events.
Pre-surgical evaluation: Comprehensive assessment—including seizure localisation, neuroimaging and neurophysiological studies—to determine candidacy for epilepsy surgery.
