Active clinical trials for "Status Epilepticus"

PANGEA is an international prospective point prevalence study to describe the epidemiology, interventions, and outcomes in children with acute critical brain disease.

A prospective cohort minimal risk study to determine the impact of the COVID-19 crisis on outcomes of neurologically injured ICU patients.

In clinical practice language impairment is frequently reported in association with nocturnal epileptiform activity. There is a spectrum of epileptic conditions that are characterized by nocturnal epileptiform activity. From mild to severe this spectrum involves: Rolandic epilepsy (RE), nocturnal frontal lobe epilepsy (NFLE), Landau-Kleffner syndrome (LKS) and electrical status epilepticus during slow wave sleep (ESES). The exact characteristic of the relationship between nocturnal epileptiform activity and language impairment is yet to be explored. The investigators suggest that nocturnal epileptiform EEG discharges and nocturnal epileptic seizures during development will cause diseased neuronal networks that involve language. The diseased neuronal networks are less efficient compared with normal neuronal networks. Objective: Identification of a diseased neuronal network characteristic in children with nocturnal epileptiform activity, which can explain language impairment in these children. For this the investigators will use functional magnetic resonance imaging (MRI) to analyse brain activity and diffusion weighted MRI to investigate white matter connectivity.

The aim of the proposed research is to compare the diagnostic accuracy of a portable wireless electroencephalography (EEG) device (Biosignal Micro-EEG) to standard EEG in identifying abnormal EEG patterns (mainly non-convulsive seizure and non-convulsive status epilepticus) in emergency department (ED) patients with altered mental status. Comparing the the accuracy of EEG recordings and interpretations of Micro-EEG to those of standard EEG will allow the investigators to assess the utility of this novel device in the ED patients with altered mental status. The unique qualities of Micro-EEG device could potentially facilitate easier access to EEG test in all ED patients. This study will also provide valid information regarding the prevalence of non-convulsive seizure in ED patients with altered mental status.The gold standard for diagnosing non-convulsive seizure would be standard EEG. All study participants will undergo electroencephalography using the two devices (standard EEG and micro-EEG) and a combination of standard electrodes and Electro-Cap in a randomized order: 1. Standard EEG with standard EEG electrodes, 2. Micro-EEG with standard EEG electrodes, and 3. Micro-EEG with Electro-Cap electrodes.

This is an open-label, expanded access protocol, designed to offer treatment with SAGE-547 to subjects in SRSE, and to evaluate the efficacy and safety of SAGE-547 administered as a continuous intravenous infusion to these subjects

Phase 1: The first part of study is a multi-center, retrospect study involving 38 hospitals. The program is a national epidemiological study on status epilepticus in Chinese children.The aims of the epidemiological study include: to obtain national epidemiological data on the etiology, diagnosis,treatment,evaluation, risk factors , outcome and analyze the burden of disease. to build a Collaborative Network in pediatric status epilepticus research. to establish a national clinical database of pediatric status epilepticus. to lay the foundation for the further prospective study. Phase 2: The second part of study is a multi-center, prospective study involving 38 hospitals. The aim of the study is to set up guideline of Children with SE in China.

Electrical status epilepticus during slow wave sleep is a condition in which the epileptic patient starts to develop neurocognitive deterioration, any type of seizures and continuous electrical activity in the EEG during non rapid eye movement sleep. It is an age related condition and will resolve spontaneously at around the age of puberty. However if left untreated or treatment is delayed, it may lead to permanent neurocognitive deterioration. Thus early diagnosis and treatment is essential in these children to preserve neurocognitive function.

To evaluate the safety and efficacy of intravenous valproate in pediatric status epilepticus and acute repetitive seizures as part of seizure treatment protocol in pediatric ER

Non convulsive status epilepticus is a persistent change in behavioural and or mental process from baseline associated with continuous epileptiform activity in electroencephalograph,it occur in about 50 percent in patients with coma and convulsions and in 8-13 percent in intensive care unit patients

A large proportion of patients (up to 20%) who suffer from an epileptic seizure and remain unconscious suffer from a non-convulsive epileptic seizure. The condition is difficult to diagnose, and impossible without the required instruments. Electroencephalogram is required in the diagnosis of non-convulsive status epilepticus. Presently, the diagnostic value and implementation of such a device in the prehospital field is little studied. The aim of this study is to evaluate the diagnostic value of the acquired electroencephalogram with a prototype EEG/EKG adapter connected to a Physio-Control LifePak 15 defibrillator/monitor. The EEG is registered in a otherwise normal fashion with scalp-electrodes, but only three channels are monitored, as this is deemed sufficient for the prehospital field, as well as for monitoring the epileptic seizures.
