OBJECTIVE The efficacy of epilepsy surgery depends critically upon successful localization of the epileptogenic zone. Magnetoencephalography (MEG) enables noninvasive detection of interictal spike activity in epilepsy, which can then be localized in three dimensions using magnetic source imaging (MSI) techniques. However, the clinical value of MEG in the presurgical epilepsy evaluation is not f...
BACKGROUND Proton magnetic resonance spectroscopy (1H-MRS) is a potentially useful tool in the in vivo investigation of brain metabolites in intractable temporal lobe epilepsy (TLE). Focal N-acetylaspartate (NAA) reductions have been correlated with mesial temporal sclerosis (MTS) in surgically resected epileptogenic foci. OBJECTIVE To evaluate the abnormalities in the metabolites NAA, creati...
A brain computer interface (BCI) is a communication system converting neural activities into signals that can control computer cursors or external devices (Fetz, 2007). BCI was initially and mainly employed for patients with severe motor disorders such as amyotrophic lateral sclerosis (ALS) by providing non-muscular bidirectional communication and control. How‐ ever, the application of BCI has ...
Several studies show that the risk of accidents involving patients with epilepsy is much higher compared to the general population. The objective of this study was to identify the frequency and type of seizure related injuries in children diagnosed with epilepsy. In addition we also assessed possible risk factors associated with this seizure related accidents in childhood. This study was conduc...
objective the aim of the present study was to evaluate the efficacy and tolerability of a modified atkins diet for intractable childhood epilepsy. materials & methods twenty one children with medically intractable epilepsy were enrolled in the study. inclusion criteria were at least four seizures per month and a trial of at least three anticonvulsants without becoming seizure-free. the subjects...
PURPOSE Although epilepsy surgery, especially temporal lobe epilepsy surgery, is well established to control seizures in patients remaining on antiepileptic drug (AED) treatment, less information is available about how many seizure-free surgical patients will relapse after discontinuation of AEDs under medical supervision. METHODS A literature review yielded six retrospective clinical observa...
In this paper human normal and epileptic Electroencephalogram signals are analyzed with popular and efficient signal processing techniques like Fourier and Wavelet transform. The delta, theta, alpha, beta and gamma sub bands of EEG are obtained and studied for detection of seizure and epilepsy. The extracted feature is then applied to ANN for classification of the EEG signals. Keywords—EEG, Epi...
Epilepsy becomes one of the most frequently arising brain disorder, and it is marked by unexpected occurrence frequent seizures. In this study, University Boon Database with ictal seizure disorder diagnosis epilepsy classified making use expectation maximization features as dimensionality reduction technique followed nonlinear model, namely, Gaussian mixture logistic regression, firefly algorit...
PURPOSE This study investigates the performance of a cardiac-based seizure detection algorithm (CBSDA) that automatically triggers VNS (NCT01325623). METHODS Thirty-one patients with drug resistant epilepsy were evaluated in an epilepsy monitoring unit (EMU) to assess algorithm performance and near-term clinical benefit. Long-term efficacy and safety were evaluated with combined open and clos...
Introduction: Temporal lobe epilepsy (TLE) is the most common and drug resistant epilepsy in adults. Due to behavioral, morphologic and electrographic similarities, pilocarpine model of epilepsy best resembles TLE. This study was aimed at determination of the changes in electroencephalogram (EEG) sub-bands amplitude during focal seizures in the pilocarpine model of epilepsy. Analysis of thes...
