Over 30% epileptic patients are refractory to medication, who are amenable to neurosurgical treatment. Non-invasive brain imaging technologies including video-electroencephalogram (EEG), magnetic resonance imaging (MRI), and magnetoencephalography (MEG) are widely used in presurgical assessment of epileptic patients. This review mainly discussed the current development of clinical MEG imaging a...

This paper discusses the various methods of identifying seizure onset zone (SOZ) from intracranial electroencephalography (iEEG) data. Epilepsy, also known as disorder, is a neurological condition caused due to disruption in regular electrical communication within neuron network. With almost third epileptic conditions being drug-resistant and several cases with no cause, there need resort alter...

IMPORTANCE Seizures are believed to be common presenting symptoms in neonates and children with spontaneous intracerebral hemorrhage (ICH). However, few data are available on the epidemiology of acute symptomatic seizures or the risk for later epilepsy. OBJECTIVE To define the incidence of and explore risk factors for seizures and epilepsy in children with spontaneous ICH. Our a priori hypoth...

OBJECTIVE Brain-computer interfaces (BCIs) that are based on event-related potentials (ERPs) can estimate to which stimulus a user pays particular attention. In typical BCIs, the user silently counts the selected stimulus (which is repeatedly presented among other stimuli) in order to focus the attention. The stimulus of interest is then inferred from the electroencephalogram (EEG). Detecting a...

OBJECTIVE The aim of this case report was to study the relationship between high-frequency oscillations (HFOs), spikes, and seizures in a patient with temporal lobe epilepsy. INTRODUCTION During intracranial electroencephalography (EEG), HFOs are thought to be a marker for the seizure onset zone (SOZ). High-frequency oscillations are classified into ripples with frequencies of 70-200 Hz and f...

Epilepsy is characterized by the spontaneous and unforeseeable occurrence of seizures, during which the perception or behavior of patients is disturbed. The predictability of these seizures would render novel therapeutic approaches possible. Several prediction methods have claimed to be able to predict seizures based on EEG recordings minutes in advance. However, the term seizure prediction is ...

Results and conclusion: Hypoxic ischemic encephalopathy was the most common cause of seizure in our study group; followed by hypoglycemia and intracranial bleed. HIE was the commonest cause of seizure in the first 24 hours and the commonest age of presentation of babies with HIE and seizures was the first 24 hours. Hypoglycemic seizures peaked from 2472 hours of birth. 75% of the cases of menin...

OBJECTIVE To evaluate the value of electroencephalography in patients with altered mental status in emergency departments. METHODS Demographical characteristics, types and aetiologies of seizures, and clinical outcomes of the patients were recorded. Patients were divided into 4 groups according to the complaints of admission: findings and symptoms of seizure; stroke and symptoms of stroke-rel...

Creutzfeldt-Jakob disease accounts for more than 90% of all sporadic prion disease cases. The molecular MM2 genotype has been divided into cortical and thalamic subtypes based on structures involved and is characterized clinically by progressive dementia without ataxia or typical electroencephalography changes. Proposed diagnostic criteria for MM2 cortical type sporadic Creutzfeldt-Jakob diseas...
