Objective
This study was undertaken to develop a standardized grading system based on expert consensus for evaluating the level of confidence in the localization of the epileptogenic zone (EZ) as reported in published studies, to harmonize and facilitate systematic reviews in the field of epilepsy surgery.
Methods
We conducted a Delphi study involving 22 experts from 18 countries, who were asked...
Objective
In tuberous sclerosis complex (TSC)‐associated drug‐resistant epilepsy, the optimal invasive electroencephalographic (EEG) and operative approach remains unclear. We examined the role of stereo‐EEG in TSC and used stereo‐EEG data to investigate tuber and surrounding cortex epileptogenicity.
Methods
We analyzed 18 patients with TSC who underwent stereo‐EEG (seven adults). One hundred ten...
Objective
In this study, we seek to analyze the determinants of the intracranial electroencephalography seizure onset pattern (SOP) and the impact of the SOP in predicting postsurgical seizure outcome.
Methods
To this end, we analyzed 820 seizures from 252 consecutive patients explored by stereo‐electroencephalography (total of 2148 electrodes), including various forms of focal refractory epilepsies...
ObjectivesThe study of intracerebral electroencephalography (EEG) seizure‐onset patterns is crucial to accurately define the epileptogenic zone and guide successful surgical resection. It also raises important pathophysiologic issues concerning mechanisms of seizure generation. Until now, several seizure‐onset patterns have been described using distinct recording methods (subdural, depth electrode),...
In patients diagnosed with pharmaco-resistant epilepsy, cerebral areas responsible for seizure generation can be defined by performing implantation of intracranial electrodes. The identification of the epileptogenic zone (EZ) is based on visual inspection of the intracranial electroencephalogram (IEEG) performed by highly qualified neurophysiologists. New computer-based quantitative EEG analyses have...
