Long-Term V-EEG in Epilepsy: Chronological Distribution of Recorded Events Focused on the Differential Diagnosis of Epileptic Seizures and Psychogenic Non-Epileptic Seizures Vázquez Sánchez, Fernando García López, Beatriz Gómez Menéndez, Ana Isabel Martín Santidrián, Asunción Macarrón Vicente, Jesus Hernando Asensio, Alicia Gámez Beltrán, Pedro González Bernal, Jerónimo Soto Cámara, Raúl Jiménez Barrios, María González Santos, Josefa Epileptic seizure (ES) Psychogenic non-epileptic seizure (PNES) Anti-epileptic drugs (AEDs) Video-electroencephalogram and video-electroencephalography (V-EEG) Electroencephalogram (EEG) Differential diagnosis in epilepsy is sometimes challenging. Video-electroencephalography (V-EEG) is an essential tool in the diagnosis and management of epilepsy. The prolonged duration of V-EEG recording increases the diagnostic yield of a conventional V-EEG. The right length of monitoring for different indications is still to be established. We present a retrospective descriptive study with a sample of 50 patients with long-term V-EEG monitoring, with a mean age of 36.1 years, monitored from 2013 to 2019 at the Burgos University Hospital. The mean monitoring time was 3.6 days. Events were obtained in 76% of the patients, corresponding to epileptic seizures (ES) in 57.9% of them, with psychogenic non-epileptic seizures (PNES) in 39.5%, and with episodes of both pathologies in 2.6% of the patients. We found that the first event was highly representative, and it correlated with the rest of the events that would be recorded. Moreover, 92% of the first PNES had been captured at the end of the second day, and 89% of the first ES by the end of the third day. V-EEG for differential diagnosis between ES and PNES can be performed in hospitals without specialized epilepsy surgery units. For this indication, the duration of long-term V-EEG can be adjusted individually depending on the nature of the first event. 2024-02-02 2024-02-02 2021 info:eu-repo/semantics/article 2077-0383 http://hdl.handle.net/10259/8565 10.3390/jcm10102080 2077-0383 eng Journal of Clinical Medicine. 2021, V. 10, n. 10, 2080 https://doi.org/10.3390/jcm10102080 http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Atribución 4.0 Internacional MDPI
