Ann Biomed Eng 2019 Mar 4;47(3):706-713. Epub 2019 Jan 4.

Faculty of Biomedical Sciences and Engineering, Tampere University of Technology, Tampere, Finland.

The histological structure of tumour tissues differs from healthy brain tissues. It can therefore be assumed that there are differences also in the electrical characteristics of these tissues. The electrical characteristics of the tissues define how electric current is distributed within volume conductors, such as the human body or head. Read More

Surgical strategy for temporal lobe epilepsy with dual pathology and incomplete evidence from EEG and neuroimaging.

Exp Ther Med 2018 Dec 19;16(6):4886-4892. Epub 2018 Sep 19.

Department of Neurosurgery, The Second Hospital of Dalian Medical University, Dalian, Liaoning 116000, P.R. China.

Coexistence of hippocampal sclerosis (HS) and a temporal neocortical lesion, including focal cortical dysplasia, vascular malformations or benign primary brain tumors, is defined as dual pathology. In the majority of cases, the complete evidence based on electroencephalogram (EEG) and magnetic resonance imaging (MRI) for each of the dual pathological lesions is difficult to obtain. As a result, patients with dual pathology are poor surgical candidates due to potential incomplete resection of the epileptogenic zone. Read More

Ictal SPECT reveals different epileptogenic zones in frontal lobe epilepsy.

Epileptic Disord 2018 Oct;20(5):447-450

Epilepsy Center, Department of Neurology, University of Munich, Munich, Germany.

We report a patient with frontal lobe epilepsy due to a right frontal astrocytoma (WHO Grade III) in whom two ictal SPECTs (single photon emission tomography) were performed during two seizures with different semiology and different EEG seizure patterns. Subtraction of ictal and interictal SPECT showed right lateral frontal hyperperfusion during a left face clonic seizure, and right mesial fronto-polar hyperperfusion during a subclinical seizure. This report demonstrates that ictal SPECT may reflect different seizure semiology from the frontal lobe of the same individual and that simultaneous EEG is indispensable for the correct interpretation of SPECT in epilepsy.

Oscillatory brain activity associates with neuroligin-3 expression and predicts progression free survival in patients with diffuse glioma.

J Neurooncol 2018 Nov 9;140(2):403-412. Epub 2018 Aug 9.

Department of Anatomy & Neurosciences, VU University Medical Center, De Boelelaan 1117, 1081 HV, Amsterdam, The Netherlands.

Introduction: Diffuse gliomas have local and global effects on neurophysiological brain functioning, which are often seen as 'passive' consequences of the tumor. However, seminal preclinical work has shown a prominent role for neuronal activity in glioma growth: mediated by neuroligin-3 (NLGN3), increased neuronal activity causes faster glioma growth. It is unclear whether the same holds true in patients. Read More

[The management of patients with new epileptic seizures in the early period after resection of hemispheric tumors: two case reports and a literature review].

Zh Vopr Neirokhir Im N N Burdenko 2017;81(5):96-103

Burdenko Neurosurgical Institute, Moscow, Russia.

Epileptic seizures developing for the first time after a neurosurgical intervention (de novo seizures) are a challenge for choosing an optimal treatment. The pathogenesis of these seizures is often associated with factors that become inactive in the early postoperative period. These seizures can not serve the basis for diagnosing symptomatic epilepsy and should be regarded as a brain response to surgery, and patients do not need anticonvulsant therapy that reduces the quality of life.

Brain Tumor-Related Epilepsy: a Current Review of the Etiologic Basis and Diagnostic and Treatment Approaches.

Curr Neurol Neurosci Rep 2017 Sep;17(9):70

Northeast Regional Epilepsy Group, 95 Madison Ave, Suite 306, Morristown, NJ, 07960, USA.

Purpose Of Review: The relationship of brain tumors and seizures remains poorly understood. This article is an overview of the epidemiology, etiology, and diagnostic and treatment approaches of tumor-related epilepsy primarily with regard to glial-based tumors, the most commonly considered brain tumor in this field.

Recent Findings: Over the past many years, several novel etiologic mechanisms to explain how tumors induce seizures have been developed, which this article reviews, including the roles of glutamate-induced excitotoxicity, matrix metalloproteinases, isocitrate dehydrogenase, methylguanine methyltransferase, and functional network connectivity.
