Rhythmic EEG patterns: The oldest idea in the EEG world, but without an obvious definition Open
The word "rhythmic" was quickly introduced in the vocabulary of the electroencephalographers with the discovery of the alpha rhythm and typical discharges of spike-and-waves at 3 Hz in childhood absence epilepsy, but without any definition…

Electrophysiological Signatures of Alpha Coma Open
Purpose: Recent research on quantitative EEG in coma has proposed several metrics correlating with consciousness level. However, the heterogeneous nature of coma can challenge the generalizability of these measures. This study investigates…

Triphasic waves: To treat or not to treat? Open
Generalized periodic discharges (GPDs) with triphasic morphology (triphasic waves, TWs) are EEG waveforms that have been a frequent topic of research evaluating their etiology and clinical correlates. More specifically, prior studies have …

Improving Clinician Performance in Classifying EEG Patterns on the Ictal–Interictal Injury Continuum Using Interpretable Machine Learning Open
Users showed significant pattern classification accuracy improvement with the assistance of this interpretable deep-learning model. The interpretable design facilitates effective human-AI collaboration; this system may improve diagnosis an…

Stimulus‐induced arousal with transient electroencephalographic improvement distinguishes nonictal from ictal generalized periodic discharges Open
In the case of suspicion of nonconvulsive status epilepticus (NCSE), reactivity on electroencephalograms (EEGs) can provide valuable diagnostic information. Reactivity refers to responses to auditory or somatosensory stimulation, with chan…

Electroencephalography in encephalopathy and encephalitis Open
Electroencephalography (EEG) is a useful adjunct to clinical neurological examination, particularly as it may detect subtle or subclinical disturbance of cerebral function and it allows monitoring of cerebral activity over time. Continuous…

Diagnosing nonconvulsive status epilepticus: Defining electroencephalographic and clinical response to diagnostic intravenous antiseizure medication trials Open
Objective The Salzburg criteria for nonconvulsive status epilepticus (NCSE) and the American Clinical Neurophysiology Society (ACNS) Standardized Critical Care EEG Terminology 2021 include a diagnostic trial with intravenous (IV) antiseizu…

Managing Antiseizure Medications in Pregnancy Open
This study demonstrates that frequency and timing of ASM level monitoring may not affect overall seizure outcomes during pregnancy in those on lamotrigine or levetiracetam. Furthermore, one can consider preemptive dose adjustments or a lab…

Life Stressors During Pregnancy in Women With Epilepsy Open
Although managing stress is important in both epilepsy and pregnancy, WWE experience more stressors than do WWoE. After adjusting for maternal age, race, and SES, this increase in stressors persisted. Women who were younger, with lower inc…

Development of Expert-Level Classification of Seizures and Rhythmic and Periodic Patterns During EEG Interpretation Open
This study provides Class II evidence that among patients with epilepsy or critical illness undergoing EEG monitoring, SPaRCNet can differentiate (IIIC) patterns from non-IIIC events and expert neurophysiologists.

Interrater Reliability of Expert Electroencephalographers Identifying Seizures and Rhythmic and Periodic Patterns in EEGs Open
This study provides Class II evidence that an independent expert review reliably identifies ictal-interictal injury continuum patterns on EEG compared with expert consensus.

How to evaluate and assess the epileptogenic/seizure potential of periodic discharges along the ictal-interictal continuum? Open
The ictal–interictal continuum (IIC) is a concept used for those particular EEG patterns that do not meet the strict criteria for status epilepticus but may be associated with neuronal injury. The aim of this article is to review equivocal…

Nonconvulsive status epilepticus following cardiac arrest: overlooked, untreated and misjudged Open
Aims Seizures and status epilepticus (SE) are detected in almost a third of the comatose cardiac arrest survivors. As the literature is quite exhaustive regarding SE with motor symptoms in those patients, little is known about nonconvulsiv…

Measuring expertise in identifying interictal epileptiform discharges Open
Objective . Interictal epileptiform discharges on EEG are integral to diagnosing epilepsy. However, EEGs are interpreted by readers with and without specialty training, and there is no accepted method to assess skill in interpretation. We …

Lateralized Periodic Discharges: Which patterns are interictal, ictal, or peri-ictal? Open
There is an ongoing debate if Lateralized Periodic Discharges (LPDs) represent an interictal pattern reflecting non-specific but irritative brain injury, or conversely, is an ictal pattern. The challenge is: how to correctly manage these p…
