OBJECTIVE: Currently, approximately 60-70% of patients with unilateral temporal lobe epilepsy (TLE) remain seizure-free 3 years after surgery. The goal of this work was to develop a presurgical connectivity-based biomarker to identify those patients who will have an unfavorable seizure outcome 1-year postsurgery. METHODS: Resting-state functional and diffusion-weighted 3T magnetic resonance imaging (MRI) was acquired from 22 unilateral (15 right, 7 left) patients with TLE and 35 healthy controls...

PURPOSE: Some studies have suggested that BAFF and BAFFR are highly expressed in the central nervous system (CNS) and participate in inflammatory and immune associated diseases. However, whether BAFF and BAFFR are involved in the pathogenesis of epilepsy remains unknown. This study aimed to investigate the expression of BAFF and BAFFR proteins in the brains of patients with temporal lobe epilepsy (TLE) and in a pilocarpine-induced rat model of TLE to identify possible roles of the BAFF-BAFFR signaling pathway in epileptogenesis...

Temporal lobe epilepsy (TLE) is a common and severe neurological disorder which is often intractable. It can not only damage the normal structure and function of hippocampus, but also affect the neurogenesis in dentate gyrus (DG). It is well documented from researches on the animal models of TLE that after a latent period of several days, prolonged seizure activity leads to a dramatic increase in mitotic activity in the hippocampal DG. However, cell proliferation returns to baseline levels within 3-4 weeks after status epilepticus (SE)...

The insula is now regarded as a potential site of epileptogenesis in drug-resistant epilepsy, and the advent of microsurgical techniques has allowed insular cortectomy to become a treatment of choice when the insular cortex is involved in the seizure focus. However, considering the evidence of an insular role in socio-emotional processing, it remains unknown whether these cortical resections disturb personality and social behavior as experienced in daily life. We examined such changes in a group of patients (n=19) who underwent epilepsy surgery involving partial or complete resection of the insula, and compared them to a group of patients who underwent standard temporal lobe epilepsy (TLE) surgery (n=19) as a lesion-control group...

Adult neurogenesis is significantly increased in the hippocampus of rodent models of temporal lobe epilepsy (TLE). These adult-generated neurons have recently been shown to play a contributing role in the development of spontaneous recurrent seizures (SRS). In order to eventually target pro-epileptic adult neurogenesis in the clinical setting, it will be important to identify molecular players involved in the control of aberrant neurogenesis after seizures. Here, we focused on NeuroD1 (ND1), a member of the bHLH family of transcription factors previously shown to play an essential role in the differentiation and maturation of adult-generated neurons in the hippocampus...

OBJECTIVES: In this case series, the findings of 85 functional MRI studies employing a dynamic fearful face paradigm are reported. Previous findings have shown the paradigm to generate bilateral amygdala activations in healthy subjects and unilateral activations in patients with MTLE, in the contralateral hemisphere to seizure origin. Such findings suggest ipsilateral limbic pathology and offer collateral evidence in lateralizing MTLE. METHODS: The series includes 60 patients with TLE, 12 patients with extra-temporal lobe epilepsy, and 13 healthy controls...

INTRODUCTION: A Lead Extraction Difficulty (LED) score was proposed to predict the difficult transvenous lead extraction (TLE) procedures, defined by means of the fluoroscopy time. The aim of this study was to validate the estimation model based on the LED index above 10 on an independent data set of TLE cases. METHODS: Consecutive patients undergoing TLE between January 2014 and January 2016 were included in this analysis. The fluoroscopy time related to the leads removal was dichotomized as above or below its 90(th) percentile (PCTL)...

Temporal lobe epilepsy (TLE) surgery is an effective procedure that can produce cognitive changes. However, the prognostic factors related with cognitive outcomes need to be better understood. The aim of the present study is to know if age at surgery is a reliable predictor of verbal memory competence and considering factors such as: hemisphere; type of surgery; pre-surgical seizure frequency; and epilepsy duration. Sixty-one typically dominant patients with drug-resistant TLE (34 with left TLE [L-TLE] and 27 with right TLE [R-TLE]) underwent a neuropsychological assessment before and a year after surgery...

Previous studies have demonstrated executive dysfunction in patients with temporal lobe epilepsy (TLE). Frontal assessment battery (FAB) is a short neuropsychological tool that was developed for assessment of frontal lobe function in a clinical setting. The aim of the present study is to evaluate the clinical utility of FAB for detection of executive dysfunction in TLE patients. Forty-eight TLE patients and 48 sex and age-matched healthy controls participated in this study. Compared to healthy participants, the total FAB score was significantly lower among the TLE patients...

Temporal lobe resection is the most prevalent epilepsy surgery procedure. However, there is no consensus on the best surgical approach to treat temporal lobe epilepsy. Complication rates are low and efficacy is very high regarding seizures after such procedures. However, there is still ample controversy regarding the best surgical approach to warrant maximum seizure control with minimal functional deficits. We describe the most frequently used microsurgical techniques for removal of both the lateral and mesial temporal lobe structures in the treatment of medically intractable temporal lobe epilepsy (TLE) due to mesial temporal sclerosis (corticoamygdalohippocampectomy and selective amygdalohippocampectomy)...

Normal differentiation and induced reprogramming require the activation of target cell programs and silencing of donor cell programs. In reprogramming, the same factors are often used to reprogram many different donor cell types. As most developmental repressors, such as RE1-silencing transcription factor (REST) and Groucho (also known as TLE), are considered lineage-specific repressors, it remains unclear how identical combinations of transcription factors can silence so many different donor programs. Distinct lineage repressors would have to be induced in different donor cell types...

Febrile seizures (FS) are the most common seizure disorders in children aged 6 months to 5 years. Children suffering from complex FS have a high risk of developing subsequent temporal lobe epilepsy (TLE). Neuroinflammation is involved in the pathogenesis of FS although the mechanism remains unknown. Our previous study using the Whole Rat Genome Oligo Microarray determined that Dipeptidyl peptidase IV (DPP4) is potentially a related gene in FS rats. In this study, we demonstrated that DPP4 expression was significantly increased at both the protein and mRNA levels after hyperthermia induction...

INTRODUCTION: Antibodies directed against neuronal surface antigens have recently been identified in patients with focal temporal lobe epilepsy (TLE) of unknown cause and mesial TLE with hippocampal sclerosis (MTLE-HS), thereby emphasizing the role of autoimmunity in TLE. Antibodies to contactin-associated protein-like 2 (CASPR2) are prevalent in MTLE-HS patients. We aimed to find out whether anti-neuronal autoimmunity might be involved in CASPR2 antibody-related MTLE-HS. METHODS: Surgically resected medial temporal lobe specimens of seropositive and seronegative MTLE-HS patients were examined with hematoxylin and eosin and immunohistochemical staining using specific immune cell markers...

OBJECTIVES: The diet and subsistence in Iron-Age Öland is debated as earlier studies and different archaeological sources seemingly provide conflicting interpretations. The objectives of this study are therefore to: (i) add new insights on diet and (ii) investigate the chronological variation in detail. It is common in studies of diet to investigate differences between datasets defined by archaeological periods (determined by artefact typology), but it is rare to explore whether these dietary changes are, in fact, well correlated with these temporal categories or not...

Aims: Non-laser-based methods are safe in lead extraction but in the past have been less effective than laser methods. In the past decade, new equipment has been introduced including the Evolution® Mechanical Dilator Sheath and the Evolution® RL. We sought to determine the impact of new equipment on outcome in mechanical lead extraction. Methods and results: We considered 288 consecutive patients (age 66 ± 18 years) who underwent transvenous lead extraction (TLE) of 522 leads in the decade to the end of 2014...

The subiculum is the main output of the hippocampal formation. A high proportion of its principal neurons fire action potentials in bursts triggered by the activation of low threshold calcium currents. This firing pattern promotes synaptic release and regulates spike-timing-dependent plasticity. The subiculum receives a high density of fibers originating from the raphe nuclei, suggesting that serotonin (5-HT) modulates subicular neurons. Here we investigated if and how 5-HT modulates the firing pattern of bursting neurons...
