The localizing value of ictal EEG
in focal epilepsy.
No loss of consciousness or drop occurred during the attacks, and ictal EEG
showed no epileptiform changes.
Differences between Generalised Tonic-Clonic and Focal-onset Seizures evolving to Generalised Tonic-Clonic Seizures Differences GTCS ->GTCS Aura No A->B->C, A->C/B->C Focal brain lesion No Active or scar lesion Inter-ictal EEG
Brief Generalised Focal spike and wave spike and wave Ictal EEG
Generalised spike Focal evolving spiky rhythm and wave A = Aura; B = Blank; C = GTCS.
Greater ictal EEG amplitude, intensity, and symmetry obtained with bilateral ECT are not common with longer seizures, but they are related to antidepressant outcome.
The ictal EEG as a marker of adequate stimulus intensity with unilateral ECT.
In the surgical treatment group there were 12 patients without an ictal EEG.
Patients who had interictal bilateral epileptiform discharges or discordant MRI lesions had ictal EEGs recorded during onset at V/ EEG.
Association of combined MRI, interictal EEG, and ictal EEG
results with outcome and pathology after temporal lobectomy.
Some studies report that ictal EEG
indices may be markers of relative stimulus intensity that might indicate a successful treatment (11).

, rhythmic spike-slow waves are found predominantly in the centrotemporal region.
