Rhinal and hippocampal event-related potentials as epileptogenic zone markers in the pre-surgical evaluation of temporal epilepsies: a systematic review

Arquivos de Neuro-Psiquiatria, 2023
Background Cognitive event-related potentials (ERPs) allow for lateralization of the epileptogenic zone (EZ) to estimate the reserve of memory in the contralateral non-epileptogenic hemisphere, and to investigate the prognosis of temporal lobe seizure ...

Stereoelectroencephalography in pre-surgical evaluation of patients with drug-resistant focal epilepsy

Эпилепсия и пароксизмальные состояния, 2022
Background. Surgical treatment has shown its effectiveness for patients with drug-resistant focal epilepsy: resection or disconnection of the epileptogenic zone leads to relief from epileptic seizures.

Electroclinical characteristics of MRI negative focal epilepsy: A video-EEG study [PDF]

Vojnosanitetski Pregled, 2020
Background/Aim. Epileptogenic lesions carry intrinsic epileptogenicity or epileptogenic potential in their close vicinity. One third of patients with focal epilepsy have no epileptogenic lesions magnetic resonance imaging [MRI(-)].

Dynamic imaging of coherent sources reveals different network connectivity underlying the generation and perpetuation of epileptic seizures [PDF]

, 2013
The concept of focal epilepsies includes a seizure origin in brain regions with hyper synchronous activity (epileptogenic zone and seizure onset zone) and a complex epileptic network of different brain areas involved in the generation, propagation, and ...

A case of clinical worsening after stereo-electroencephalographic-guided radiofrequency thermocoagulation in a patient with polymicrogyria

Epilepsy & Behavior Reports, 2023
Radiofrequency thermocoagulation (RF-TC) is a wide-used procedure for drug-resistant epilepsy. The technique is considered safe with an overall risk of 1.1% of permanent complications, mainly focal neurological deficits.
