Intracranial EEG seizure onset patterns in unilateral temporal lobe epilepsy and their relationship to other variables

Original language description

Objective: We performed a retrospective study to determine the different types of seizure onset patterns (SOP) in invasive EEG (IEEG) in patients with temporal lobe epilepsy (TLE). Methods: We analyzed a group of 51 patients (158 seizures) with TLE who underwent IEEG. We analyzed the dominant frequency during the first 3 s after the onset of ictal activity. The cut-off value for distinguishing between fast and slow frequencies was 8 Hz. We defined three types of SOPs: (1) fast ictal activity (FIA) - frequency &gt;= 8 Hz; (2) slow ictal activity (SIA) - frequency &lt;8 Hz; and (3) attenuation of background activity (AT) - no clear-cut rhythmic activity during the first 3 s associated with changes of IEEG signal (increase of frequency, decrease of amplitude). We tried to find the relationship between different SOP types and surgery outcome, histopathological findings, and SOZ localization. Results: The most frequent SOP was FIA, which was present in 67% of patients.
