PURPOSE: Mesial Temporal Lobe Epilepsy with Hippocampal Sclerosis (MTLE-HS) is the most frequent pharmaco-resistant epilepsy. It has been associated with febrile seizures (FS) in childhood. Its aetiology remains unclear but genetic factors are involved. Apolipoprotein E (ApoE) is the main lipoprotein secreted in brain. It has a critical immunomodulatory function, influences neurotransmission and it is involved in repairing damaged neurons. ApoEϵ4 is an isoform of ApoE with altered protein function, previously associated with refractoriness and early onset epilepsy...

BACKGROUND: We sought to provide an assessment of the burden of neurocysticercosis among people with epilepsy (PWE) in Bhutan and evaluate the yield of various tests for Taenia solium. METHODS: PWE were enrolled at the National Referral Hospital in Thimphu (2014-2015). Serum was tested for anti-Taenia solium IgG using ELISA (Ab-ELISA), enzyme-linked immunoelectrotransfer blot (EITB), and parasite antigen. Results were compared to brain MRI. Participants were categorized as definite neurocysticercosis (MRI and EITB positive), probable neurocysticercosis (MRI or EITB positive), or without neurocysticercosis...

Ictal kissing is a rare semiological manifestation in patients with epilepsy. We tried to estimate its occurrence and characterize the underlying etiology. We retrospectively reviewed all video-EEG reports from Jefferson Comprehensive Epilepsy Center over a 12-year period (2004-2015) for the occurrence of the term "kiss". We then searched the electronic database PubMed on September 21, 2016 using the following search terms in the English language: "ictal" OR "seizure" OR "epilepsy" AND "kiss" OR "kissing". Relevant original studies were included...

BACKGROUND: Mesial temporal sclerosis (MTS) is the most common disease found in an epilepsy surgery series. Early age of onset, a history of febrile convulsions, epileptiform discharges on EEG, duration of epilepsy, number of generalized seizures and severity of psychiatric disorders are possible prognostic factors in patients with MTS. OBJECTIVE: The aim of this study is to review the clinical, semiotic, psychological, electrophysiological and neuroradiological researches and relate their findings to the prognosis of patients with MTS who underwent anteromedial temporal lobectomy (ATL)...

PURPOSE OF REVIEW: This article discusses structural and functional neuroimaging findings in patients with seizures and epilepsy. The indications for neuroimaging in these patients and the potential diagnostic utility of these studies are presented. RECENT FINDINGS: Patients presenting with new seizures typically require urgent imaging to rule out a critical underlying cause. MRI is the structural neuroimaging procedure of choice in individuals with epilepsy. Specific epilepsy protocols should be considered to increase the diagnostic yield of neuroimaging in patients with structural lesions associated with focal or generalized seizures...

It is largely recognized that the mesial temporal lobe and its substructure support declarative long-term memory (LTM). So far, different theories have been suggested, and the organization of declarative verbal LTM in the brain is still a matter of debate. In the current study, we retrospectively selected 151 right-handed patients with temporal lobe epilepsy with and without hippocampal sclerosis, with a homogeneous (seizure-free) clinical outcome. We analyzed verbal memory performance within a normalized scores context, by means of prose recall and word paired-associate learning tasks...

PURPOSE: There is controversy about relative contributions of ictal scalp video EEG recording (vEEG), routine scalp outpatient interictal EEG (rEEG), intracranial EEG (iEEG) and MRI for predicting seizure-free outcomes after temporal lobectomy. We reviewed NIH experience to determine contributions at specific time points as well as long-term predictive value of standard pre-surgical investigations. METHODS: Raw data was obtained via retrospective chart review of 151 patients...

OBJECTIVE: To define the functional network changes that characterize MRI-negative temporal lobe epilepsy (TLE) and TLE with hippocampal sclerosis (HS-TLE). METHODS: We studied 36 patients with medically refractory unilateral TLE, having either a normal clinical MRI (n = 18) or unilateral hippocampal sclerosis (n = 18). Patients were compared to healthy controls of equivalent age and sex (n = 27). Functional connectivity in 10 minutes of task-free functional MRI was assessed using a voxel-resolution graph theoretic analysis, using the metrics of degree, clustering coefficient, eigenvector, and betweenness centrality...

Temporal lobe epilepsy (TLE) is a highly prevalent syndrome among people with epilepsy, and is usually refractory to drug treatment. Structural and physiological changes, such as hippocampal sclerosis, are often present in TLE patients. The objective of this study is to evaluate the feasibility and safety of intra-arterial infusion of autologous bone marrow mononuclear cells (BMMC) in adults with medically refractory mesial temporal lobe epilepsy (MTLE) and unilateral hippocampal sclerosis (MTLE-HS). We enrolled 20 patients that had been diagnosed with MTLE-HS and refractory to medical treatment...

Epilepsy is one of the most common neurological disorders characterized by recurrent seizures due to neuronal hyperexcitability. Here we compared miRNA expression patterns in mesial temporal lobe epilepsy with and without hippocampal sclerosis (mTLE + HS and mTLE -HS) to investigate the regulatory mechanisms differentiating both patient groups. Whole genome miRNA sequencing in surgically resected hippocampi did not reveal obvious differences in expression profiles between the two groups of patients. However, one microRNA (miR-184) was significantly dysregulated, which was confirmed by qPCR...

Mesial temporal lobe epilepsy (MTLE) is frequently associated with hippocampal sclerosis (Hs), possibly caused by a primary brain injury that occurs a long time before the appearance of neurological symptoms. MTLE-Hs is, however, a heterogeneous condition that evolves with time, involving both environmental and genetic components. Recent experimental studies emphasize that drugs or drug combinations that target modulation and circuitry reorganization of the epileptogenic networks favorably modify the complex molecular and cellular alterations underlying MTLE...

PURPOSE: Cases of temporal lobe epilepsy (TLE) with ipsilateral amygdala enlargement (AE) have increasingly been reported. However, the white matter (WM) abnormalities of TLE patients with AE remain poorly investigated. Here we explored macrostructural and microstructural WM abnormalities in TLE patients with AE compared to normal controls and TLE patients with hippocampal sclerosis (HS). MATERIAL AND METHODS: We selected 17 patients with unilateral TLE with AE (TLE-AE) based on automated amygdala volumetry using FreeSurfer software, and 34 healthy controls and 35 patients with unilateral TLE with HS (TLE-HS) were also recruited...

BACKGROUND: Hippocampal sclerosis (HS) is a common pathology in MTLE, patients may show different surgical outcomes and clinical features. The 2013 ILAE classification subdivides HS into 3 types (HS type 1: severe neuronal loss and gliosis predominantly in CA1 and CA4 regions; - HS type 2: CA1 predominant; HS type 3: CA4 predominant) and includes "gliosis only, as no-HS". The association of clinical and electrophysiological findings with different HS types has not been reported previously in detail...

UNLABELLED: The mediobasal temporal region (MTR) is located near the brain stem and surrounded by the eloquent neurovascular structures. The supracerebellar transtentorial approach (STA) is safe access to the posterior MTR structures, however its use for resection of anterior MTR lesions still remains controversial. The article describes the technique and outcome of surgery for different MTR structures using STA. MATERIAL AND METHODS: The paramedian STA was used in 18 patients (13 females and 5 males) for 7 years...
