Seizure localization, cortical propagation and subcortical activation pathways using ictal
Interictal psychopathology in patients with ictal
fear: A quantitative investigation.
In addition to the clinical aspects considered above, there are some other issues that can help in the differentiation of these two ictal
This method of ictal
brain SPECT testing is cost effective and sensitive in the identification of presurgical localization of seizure focus in children (Kottamasu, 1997, p.
single photon emission computed tomography (SPECT) scan is used as a diagnostic tool for the surgical treatment of epilepsy patients.
Before the patient is offered the procedure several factors need to be weighed, including the nature of the seizures, ictal
or interictal behavior which may be difficult to control, and the degree of cooperation which can be expected from the patient.
Steps should be taken to manage any patient prone to pulling off scalp electrodes during seizures or the post ictal
events have been produced by stimulation of the lateral superior temporal lobe, specifically in the transverse gyrus of Heschl.
Specifically, prior research in patients with MTLE lias shown that autonomic reflexes during the ictal
phase of a seizure may evoke cardiac rhythm changes in 92% of patients (Koseoglu, Kucuk, Arman, & Ersoy, 2009).
Since epileptogenic spikes last just milliseconds, only very frequent ictal
activity or longstanding interictal activity might be localized with fMRI.
Also, spatiotemporal changes in preictal spike activity in human temporal lobe epilepsy  revealed that the degree of bilateral interdependence in medial temporal lobe spike activity increased prior to onset of a seizure, thus indicating that spikes may herald the interictal to ictal
