Febrile seizures (FS) are the most common seizures seen in the paediatric population in the out-of-hospital and emergency department settings, and they account for the majority of seizures seen in children younger than 5 years old. An FS is a seizure accompanied by fever, without central nervous system infection, occurring in children between 6 months and 5 years old. Five criteria have been used and taught to classify any FS as simple or complex FS. These factors do not bear the same significance for clinical practice, in particular, the decision to perform a lumbar puncture for cerebrospinal fluid analysis to rule out an intracranial infection...

BACKGROUND: Solitary calcified neurocysticercosis is a common cause of seizures in the developing countries. Factors responsible for seizure recurrence in patients with solitary calcified neurocysticercosis are not known. We evaluated the clinical, neuroimaging and biochemical predictors of seizure recurrence. METHODS: This was a prospective observational study. Patients with new-onset seizures and a solitary calcified neurocysticercosis were included. Patients were evaluated clinically; baseline electroencephalography and magnetic resonance imaging of brain were done for all patients...

We describe a patient with chronic pharmacoresistant epilepsy related to right parietal focal cortical dysplasia (FCD), who became seizure-free following an episode of convulsive status epilepticus (SE). Magnetic resonance imaging (MRI) and fludeoxyglucose positron emission tomography (FDG-PET) were performed before and after SE. Longitudinal MRI scans showed a stable appearance of the FCD with no new signal change. However, diffusion tensor imaging showed altered white matter fiber tract orientation in posterior cortices, especially in proximity to the lesion, at 3 years post-SE...

PURPOSE: The purpose of this study was to compare the efficacy and safety of lacosamide (LCM) and sodium valproate (SVA) in lorazepam (LOR)-resistant SE. METHODS: Patients with LOR-resistant SE were randomized to intravenous LCM 400mg at the rate of 60mg/kg/min or SVA 30mg/kg at the rate of 100mg/min. The SE severity score (STESS), duration of SE and its etiology, and MRI findings were noted. Primary outcome was seizure cessation for 1h, and secondary outcomes were 24h seizure remission, in-hospital death, and severe adverse events (SAE)...

BACKGROUND: Neurological complications in liver failure are common. Often under-recognized neurological complications are seizures and status epilepticus. These may go unrecognized without continuous electroencephalography (CEEG). We highlight the observed electro-radiological changes in patients with grade III/IV hepatic encephalopathy (HE) found to have seizures and/or status epilepticus on CEEG and the associated neuroimaging. METHODS: This study was a retrospective review of patients with West Haven grade III/IV HE and seizures/status epilepticus on CEEG...

BACKGROUND: Patients with arterial perinatal stroke often suffer long-term motor sequelae, difficulties in language, social development, and behaviour as well as epilepsy. Despite homogeneous lesions, long-term behavioural and cognitive outcomes are variable and unpredictable. Sleep-related epileptic encephalopathies can occur after early brain injury and are associated with global developmental delays. We hypothesized that sleep-potentiated epileptiform abnormalities are associated with worse developmental outcomes after perinatal stroke...

Gelastic seizures (GS) are typically associated with hypothalamic hamartomas and present during childhood. However it is now known that GS can be found in focal epilepsies arising from other regions in the brain, including mesial and neocortical frontal, temporal and parietal regions. GS have rarely been described as the presenting manifestation of New Onset Refractory Status Epilepticus (NORSE). In this article we describe a previously healthy 3-year-old who presented with an explosive onset of GS that were refractory to multiple anti-seizure medications...

INTRODUCTION: Refractory epilepsy is a common clinical manifestation in patients with tuberous sclerosis complex (TSC), which can be complicated by many life-threatening conditions, such as status epilepticus (SE). However, very few reports mention the patterns and semiology of SE in those patients. OBJECTIVE: To study the clinical characteristics and outcomes of SE in TSC patients. MATERIALS AND METHODS: This observational, prospective study was carried out on 36 Egyptian children with definite TSC...

PURPOSE: Seizure induced neuronal hyperexcitability and increased unmet metabolic neuronal demand results in failure of the sodium/potassium ATP pump. Sodium and water accumulates intracellularly with cellular swelling and reduced extracellular volume demonstrating hyperintensity on DWI and reduced ADC. The aim of this study was to describe 4 clinical cases where we identified abnormalities in diffusion restriction in the acute peri-ictal period and followed them longitudinally. METHODS: Patients were recruited from the emergency department, clinical consultation service and epilepsy monitoring unit of two tertiary referral centres...

Insights into the dynamic changes in molecular processes occurring in the brain during epileptogenesis can substantially improve our understanding of their pathogenetic relevance. In this context, neuroinflammation is a potential mechanism of epileptogenesis which has recently been investigated in animal models by MRI or PET molecular imaging. Here, we developed an alternative and complementary molecular imaging strategy by designing a serotype 8 recombinant adeno-associated virus (AAV8) harboring promoter fragments of the GFAP or IL-1β promoter and a luciferase reporter gene...

INTRODUCTION: Thalamo-cortical networks have mainly been studied in the generation of idiopathic (genetic) epilepsies. The purpose of this study was to analyze EEG patterns and the occurrence of focal (symptomatic) epileptic seizures in patients with acquired circumscribed thalamic lesions. PATIENTS AND METHODS: Among 596 patients with thalamic lesions, we identified 47 patients in whom circumscribed thalamic lesions were detected by MRI and who underwent an EEG examination at the same stay at hospital...

We describe a case of a child suffering from alternating hemiplegia with a heterozygous p. E815K pathogenic variant of ATP1A3. The patient started to present abnormal eye movements in the first days of life, followed by the appearance at 2 months of dystonic episodes, and later on, by recurrent episodes of alternating hemiplegia more often on the right side. A severe epilepsy started at the age of 2 years with episodes of status epilepticus since the onset which frequently recurred, requiring admission to the intensive care unit...

The risk of unprovoked seizures in population-based cohorts of cerebral infection survivors is 7-8% in developed countries, rising to considerably higher rates in resource-poor countries. The main risk factors for epilepsy after cerebral infection, besides acute seizures, are infection-associated brain lesions and status epilepticus during the acute phase. Despite the high prevalence of pharmacoresistant epilepsies after cerebral infections, especially in patients with MRI-identifiable lesions, only a small minority undergoes epilepsy surgery...

Limbic encephalitis (LE) is an autoimmune or paraneoplastic disease that affects the medial temporal lobes. The patient will usually present with cognitive impairment, psychiatric changes, and seizures. Autoimmune limbic encephalitis (LE) is a challenging diagnosis as it is not always included in the typical paraneoplastic/autoimmune panels. Anti-GAD antibodies are associated with various disease including type I diabetes mellitus, various autoimmune processes, some neoplastic and infectious diseases. Thus, it is not as specific as some of the antibodies causing LE...

Super refractory status epilepticus (SRSE) is a life-threatening condition in which seizures do not respond to third-line anticonvulsant drug therapy. SRSE is associated with high mortality. How often SRSE occurs, what are the risk factors leading to this condition, and what is the effect on clinical outcome of failure to control seizures are poorly defined. Several studies have evaluated magnetic resonance imaging (MRI) findings in status epilepticus (SE), confirming that SE may directly cause selective neuronal necrosis due to excitotoxic mechanisms, as described in clinical case reports and experimental models...

We present a case of a 38-year-old woman who was at eight weeks of gestation and was admitted to Sultan Qaboos University Hospital with refractory status epilepticus (SE). She presented with a two-day history of fever and a depressed level of consciousness that was followed with generalized tonic-clonic seizures. She progressed to refractory SE that required intubation and mechanical ventilation. Autoimmune workup was suggestive of Hashimoto's encephalopathy (HE) as suggested by the high levels of thyroid antibodies...
