Diagnostic yield of utilizing 24-72-hour video electroencephalographic monitoring in the diagnosis of seizures presenting as paroxysmal events in resource-limited settings.

Objective: Long-term video electroencephalogram monitoring (LTVEM) is a standard practice in epilepsy centers to diagnose and characterize paroxysmal events. With the lack of data on LTVEM in Africa, we aimed to determine the clinical yield of LTVEM performed for 24-72 h to diagnose seizures in an epilepsy center in Nigeria.

Methods: This was a retrospective review of all patients admitted to our Epilepsy Monitoring Unit (EMU) from September 2018 to September 2021, with monitoring lasting between 24 and 72 h.
