Background: This study compares the clinical characteristics of patients with mesial temporal lobe epilepsy with hippocampal sclerosis (mTLE-HS) with those who have temporal lobe epilepsy (TLE) due to other etiologies.   Methods : In this retrospective study all patients with a clinical diagnosis of TLE were recruited in a referral outpatient epilepsy clinic at Shiraz University of Medical Sc...

PURPOSE Dysembryoplastic neuroepithelial tumours (DNET) are an important cause of refractory partial epilepsies. They usually occur within dysplastic cortex and tend to affect the temporal lobes. The EEG of these patients is characterised by slowing and/or epileptiform abnormalities with a multifocal distribution. We studied the EEG features of epilepsy patients with a temporal lobe DNET to ass...

Patients with refractory temporal lobe epilepsy (TLE) are commonly recruited for investigational anti-epileptic drug (XAED) studies. However, the long-term outcome of TLE after exposure to XAEDs is poorly documented. In this pilot study, we report the USC Epilepsy Center's experience of 19 patients with TLE enrolled in three XAED trials. The data reinforce that TLE is a drug-resistant epilepsy,...

OBJECTIVES To define the postoperative seizure outcome and its predictors in patients with ganglioglioma-related temporal lobe epilepsy (TLE). PATIENTS AND METHODS We reviewed the pre- and post-surgical evaluation data of 23 patients with temporal lobe ganglioglioma, who had completed >or=1 year of postoperative follow-up. They comprised 4.9% of the patients with TLE and 67.6% of the tumoral ...

INTRODUCTION Studies have shown progressive cerebral damage in patients with refractory mesial temporal lobe epilepsy (MTLE). However, this has not been demonstrated in benign forms of MTLE such as familial mesial temporal lobe epilepsy (FMTLE). PURPOSE To evaluate progression of hippocampal atrophy (HA) in patients with sporadic mesial temporal lobe epilepsy (SMTLE) and FMTLE by longitudinal...

Mesial temporal lobe epilepsy (mTLE), the most common type of temporal lobe epilepsy (TLE), is particularly relevant due to its high frequency of therapeutic resistance of anti-epileptic therapies. MicroRNAs (miRNAs) have been shown to be dysregulated in epilepsy and neurodegenerative diseases, and we hypothesized that miRNAs could be involved in the pathogenesis of MTLE. The present study aime...

Background/introduction Temporal lobe epilepsy (TLE) is the most common pharmacologically refractory form of epilepsy. While it can often be effectively treated by temporal lobe surgery, that does not always eliminate seizures, and many patients are not suitable candidates for surgery. A noninvasive method to augment surgical or medical treatment of TLE would be highly useful. Low-intensity foc...

Epilepsy affects 1-2 % of the population. For 30 % of these patients, their syndrome will be refractory to medical treatment. To improve our understanding and treatment of the epilepsies, we need to develop clinically relevant animal models. As temporal lobe epilepsy is often preceded by prolonged febrile seizures and in our population associated with a focal cortical dysplasia, we hypothesised...
