Nearly all reports of seizure outcome following these procedures indicate that the best outcome group includes patients with MRI evidence of mesial temporal sclerosis (hippocampal atrophy with increased T-2 signal). The range of seizure-free outcomes for these patients is reported to be between 80% and 90%, which is typically reported as a sub ...
[28] The procedure involves resecting, or cutting away, brain tissue within the region of the temporal lobe in order to remove the seizure focus. Specific evaluation for temporal lobe resection requires convergent clinical, MRI, and EEG data in order to precisely pinpoint the focal area and boundaries of the focal area. [29] The surgery has ...
Lateral temporal lobe seizures arising from the temporal-parietal lobe junction may cause complex visual hallucinations. [2] In comparison to mesial temporal lobe seizures, lateral temporal lobe seizures are briefer duration seizures, occur with earlier loss of awareness, and are more likely become a focal to bilateral tonic-clonic seizure.

Temporal lobe epilepsy (TLE) in which the epileptic focus is in the temporal lobe, is one of the most common types of epilepsy in adolescents and adults. Hence temporal lobe resection, during which the whole temporal lobe or just a part of the temporal lobe for example the hippocampus or the amygdala is removed, is the most common epilepsy ...
Henry Gustav Molaison (February 26, 1926 – December 2, 2008), known widely as H.M., was an American who had a bilateral medial temporal lobectomy to surgically resect the anterior two thirds of his hippocampi, parahippocampal cortices, entorhinal cortices, piriform cortices, and amygdalae in an attempt to cure his epilepsy.
Kuruvilla and Flink reported that while intraoperative ECoG plays a critical role in tailored temporal lobectomies, in multiple subpial transections (MST), and in the removal of malformations of cortical development (MCDs), it has been found impractical in standard resection of medial temporal lobe epilepsy (TLE) with MRI evidence of mesial ...
Ruben Kuzniecky is a neurologist scientist who is Vice-chair academic affairs and professor of neurology at Northwell Health specializing in the field of epilepsy, epilepsy surgery and neuro-imaging. He was one of the first to recognize and prove that mesial temporal sclerosis , a common cause for difficulty in controlling temporal lobe ...
In the early 1950s, during brain mapping studies with Penfield and Jasper, Feindel discovered the role of the amygdala in patients with temporal lobe seizures, which, with related studies at the MNI, led to the operation of antero-mesial temporal lobe resection often referred to as "the Montreal procedure", an operation adopted worldwide for ...
