ObjectiveEthical decisions about an allowance for animal experiments need to be based on scientifically sound information the burden and distress associated with experimental procedure models. Thereby, species differences considered recommendations regarding evidence-based severity assessment refinement measures.MethodsA comprehensive analysis of behavioral patterns corticosterone or its metabo...

PURPOSE Status epilepticus (SE) is an important neurological emergency. Early diagnosis could improve outcomes. Traditionally, SE is defined as seizures lasting at least 30 min or repeated seizures over 30 min without recovery of consciousness. Some specialists argued that the duration of seizures qualifying as SE should be shorter and the operational definition of SE was suggested. It is uncle...

A delayed diagnosis of insulinoma remains a clinical issue. Hypoglycemic symptoms can mimic neuropsychiatric disorders such as epilepsy. A 27-year-old woman with a history of epilepsy and anti-epileptic drugs (AEDs) developed repeated seizures and neuropsychiatric symptoms after a 9-year asymptomatic interval. She had received transient treatment with AEDs before the possibility of hypoglycemia...

Hypocupraemia with normal caeruloplasmin levels was found in a 21-month-old boy admitted to hospital because of repeated seizures and failure to thrive. He had blonde curly hair, spurring of the femora and tibiae, and mild anaemia, but his mental development, electroencephalogram, and structure of the hair on microscopical examination were normal. There was a general improvement in his conditio...

Seventy patients admitted to hospital with bismuth encephalopathy had repeated clinical and EEG examinations. All the patients exhibited myoclonic jerks, but no paroxysmal features ever appeared on EEG. Computed tomography showed cortical hyperdensities. Seizures were observed in 22 patients, but epileptic EEG patterns appeared only when the bismuth blood level was below 1500 microgram/1. It is...

A 43-year-old female was treated with gamma knife radiosurgery (GKS) for right frontal arteriovenous malformation (AVM) manifesting as absence seizures. Complete nidus obliteration was confirmed on angiography 4 years after GKS. However, she experienced recurrence of her previous seizures and delayed hemorrhage occurred within the treated nidus, despite absence of abnormalities by repeated angi...

Epilepsy is a brain disease that requires distributed neuronal networks for its expression. Several characteristics of epilepsy, including its natural history, the latency between an initial insult and the first manifestation of seizures, the complex interaction of seizures with development as a function of developmental stage, the modulating effect of systemic physiological responses, and the ...

BACKGROUND Non-convulsive seizures have been reported to be common in neurocritical care patients. Many jurisdictions do not have sufficient resources to enable routine continuous electroencephalography (cEEG) and instead use primarily intermittent EEG, for which the diagnostic yield remains uncertain. Determining risk factors for epileptiform activity and seizures could help identify patients ...
