Jun 25, 2023 · The ictal-interictal continuum (IIC) refers to any rhythmic or periodic electroencephalographic (EEG) pattern with features concerning an ongoing seizure but not meeting formal electrographic criteria to be definitively characterized as ictal.

EEG correlates of high risk for seizures are categorized as ictal (during a seizure), postictal (after seizure) or interictal (between seizures). These distinctions often are unclear and arbitrary, in that the interictal-ictal boundaries are blurred for many seizures. Even so …

The Neurovista ictal dataset, which consists of only seizure segments, includes 60 seconds of preictal recordings for each of the seizure segments, which means that it could be used for both seizure prediction and detection, albeit with shorter preictal data.

Jun 13, 2022 · A screening (“spot”) EEG has revealed patterns along the ictal-interictal continuum, which increase the likelihood of subsequent seizures. Paroxysmal clinical events suspected to be possible seizures. Patients at risk for seizures which may be masked by the requirement for pharmacologic paralysis.

The ictal examination is crucial for neuroanatomic localization of seizure onset, which informs medical and neurosurgical treatment of epilepsy. Substantial variation exists in ictal examination performance in epilepsy monitoring units (EMUs). We ...

Ictal refers to a neurophysiological tool used in the study of epilepsy, particularly in cases of pharmacoresistant focal epilepsy. It involves analyzing the connectivity patterns during seizures to identify the epileptogenic zone, with the potential to provide additional information compared to traditional approaches.

Jan 28, 2023 · Observational methods are applied to collect uniform data. The goal of the ICTAL Registry is to collect high-quality information on a large number of patients, thereby allowing elucidation of the pathophysiological mechanisms involved in mortality and morbidity.

Jul 28, 2014 · In this paper, we use the time-frequency signature of ictal discharges as a priori information on the sources of interest. To extract the time-frequency signature of ictal sources, we use the Canonical Correlation Analysis (CCA) method.

Feb 2, 2023 · Our data provide evidence that interictal discharges may represent travelling waves of pathological activity that are similar to their ictal counterparts, and that both ictal and interictal discharges emerge from common epileptogenic brain regions.

ICTAL COGNITIVE assessment (ICA) is the interactive examination of memory and responsiveness during an epileptic or nonepileptic event. The unpredictability and short duration of most events complicate ictal testing.
