An unavailability of video EEG, ictal EEG
, and seizure semiology confirmation is lacking in this study.
The paper presented a comparison of various entropy methods used for the classification of normal, interictal, and ictal EEG

pattern of the patient during three-seizure attacks.
The emphasis in the literature has been on the pediatric population with typical ictal EEG
showing 2.5-4 Hz generalized spike-and-wave discharges in typical absence (occurring in the setting of IGE) and slower frequencies in atypical generalized absence seizures (occurring in patients with cryptogenic or symptomatic generalized epilepsy) .
Cai, "Feature extraction and recognition of ictal EEG
using EMD and SVM," Computers in Biology and Medicine, vol.
(19) reported a case of intense increase of theta and alpha power during the possession trance state (without ictal EEG
pattern), persisting in the recovery (post-trance) phase, which was not the case in the control participants.
No loss of consciousness or drop occurred during the attacks, and ictal EEG
showed no epileptiform changes.

The other dataset is the public ictal EEG
from the BioSource database established by Sabine Van Huffel (http:// www.esat.kuleuven.be/stadius/members/biomed/biosource.
Greater ictal EEG
amplitude, intensity, and symmetry obtained with bilateral ECT are not common with longer seizures, but they are related to antidepressant outcome.
In the surgical treatment group there were 12 patients without an ictal EEG
. Of these seven patients had long-term EEG monitoring for 12 to 42h and at least two records of complete sleep cycles at night.
