Presurgical long-term video #EEG (LT-EEG) monitoring is essential for presurgical evaluation in patients with focal epilepsy. Thus, it is crucial to investigate its yield (success) as well as potential risk factors.

This systematic #review by Griethuysen et al. (Dec. 2022) analyzed 36 LT-EEG articles (4703 pediatric and adult patients in total) and found an average yield of 85% and an average adverse events rate of 17%.

The figure shows the factors associated with a successful LT-EEG. Factors leading to adverse events were: ASM tapering, history of status epilepticus, history of focal to bilateral tonic-clonic seizures, psychiatric comorbidity, and ASM taper rate.
