the monitoring of epileptic seizures is mainly done by means of eeg (electroencephalogram) monitoring. although this method is accurate, it is not comfortable for the patient as the eeg-electrodes have to be attached to the scalp which hampers the patient’s movement. this makes long term home monitoring not feasible. in this paper the aim is to propose a seizure detection system based on accele...

PURPOSE The semiology of psychogenic non-epileptic seizures (PNES) can resemble epileptic seizures, and differentiation between epileptic seizures with no EEG-correlate and PNES can be challenging even for trained experts. Therefore, there has been a search for a quantitative measure, other than EEG and semiology that could distinguish PNES from epileptic seizures. We used ECG to measure heart ...

PURPOSE To evaluate the value of magnetoencephalography (MEG) source localization in localization of epileptic activities and predicting surgical outcome in frontal lobe epilepsies (FLE). METHODS Forty-six patients with presurgical MEG evaluation and intractable FLE surgery (28 male patients) were analyzed retrospectively with a mean follow-up of 5 years. Dipole analysis was performed for MEG...

Epilepsy is one of the common neurological disorders characterized by a sudden and recurrent malfunction of the brain that is termed “seizure”, affecting over 50 million individuals worldwide. The Electroencephalogram (EEG) is the most influential technique in detection of epileptic seizures. In recent years, many research works have been devoted to the detection of epileptic seizures based on ...

OBJECTIVE To study the correlation of randomly-tested total antiepileptic plasma levels and seizure control in a retrospectively collected group of pregnant epileptic Saudi women. METHODS The medical records of 30 Saudi epileptic female patients were reviewed during their subsequent pregnancies (total of 50). The type of antiepileptic drugs used during each pregnancy, the dose of each drug an...

The topic of this presentation is the investigation of the epileptic human brain as a nonlinear system that undergoes a phase transition (epileptic seizure). The estimated values of the largest Lyapunov exponent L over time indicated a more chaotic state postictally than ictally or preictally. The start of a seizure corresponds to a simultaneous drop in the values of L at the focal electrode si...

A seizure is the outward, observable outcome following a transient paroxysmal event in the brain. This paroxysm, or misfire, can be a single event or repetitive, resulting in an epileptic syndrome. Acute seizure management is aimed at stopping both the physical manifestation as well as the electrical synchronization occurring in the brain. Let’s review the seizure phenotypes and parts of a seiz...

In this era, big data applications including biomedical are becoming attractive as the data generation and storage is increased in the last years. The big data processing to extract knowledge becomes challenging since the data mining techniques are not adapted to the new requirements. In this study, we analyse the EEG signals for epileptic seizure detection in the big data scenario using Rotati...

Magnetic resonance imaging (MRI) is recommended for patients with epileptic seizures to rule out an underlying focal lesion. However, the radiological characteristics of epilepsy are not well elucidated. Transient periictal MRI abnormality (TPMA) refers to reversible MRI signal changes observed in epileptic patients. A 32-year-old man presented with a 2-week history of epileptic seizures, which...

PURPOSE Noninvasive magnetic resonance imaging was used to assess the evolution of seizure-induced pathology in epileptic, carrier, and normal chickens. Our objective was to determine whether repetitively evoked seizures in an epileptic fowl model of generalized seizures resulted in altered brain development. METHODS Data were obtained from seizure and control groups at 45, 90, and 180 days a...
