Occipital irregular delta activity in focal epilepsy

open access: yesEpileptic Disorders, EarlyView.
Abstract Objective Nonspecific occipital irregular delta activity (OID) is a common finding in focal epilepsy (FE). However, the significance of OID and its relationship to the underlying etiology of FE remain largely unstudied. This study aimed to investigate the relationship between OID and the etiology of FE, as well as the relationship between OID ...

Electroclinical features and dynamic network connectivity of orbitofrontal epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective Orbitofrontal epilepsy (OFE) is rare and underrecognized. This study aims to characterize electroclinical features and dynamic network connectivity of OFE and subtypes. Methods We retrospectively analyzed 17 patients with OFE who underwent stereoelectroencephalographic (SEEG) electrode implantation and epilepsy surgery at our center.

Clinical significance of subclinical seizures in epilepsy presurgical evaluation: A systematic review and meta‐analysis

open access: yesEpilepsia, EarlyView.
Abstract Objective Subclinical seizures (SCSs) remain an understudied aspect of presurgical evaluation in patients with drug‐resistant epilepsy (DRE), with uncertain prevalence, distribution among epilepsy types, and predictive value for surgical outcomes.

Epileptic arousals: A neglected clinical entity

open access: yesEpilepsia, EarlyView.
Abstract Objective Epileptic arousals (EAs) are seizures characterized solely by arousal from sleep. EAs are unrecognized in current seizure classifications. Their subtle semiology and inconsistently detectable ictal activity in scalp electroencephalography (EEG) complicate differentiation from physiological arousals (PAs). This study characterizes EAs

Moving beyond spike detection: High frequency‐driven masking improves seizure onset zone localization in intracranial electroencephalography

open access: yesEpilepsia, EarlyView.
Abstract Objective Interictal epileptiform spikes (IESs) are widely used biomarkers of epileptogenic tissue in presurgical epilepsy evaluation. However, their reliability for seizure onset zone (SOZ) localization in high‐density intracranial electroencephalography (iEEG) remains inconsistent.
