Active clinical trials for "Seizures"

In this pilot study, the researchers investigated the feasibility of a closed-loop electroencephalography (EEG) / transcranial direct current stimulation (tDCS) system for treatment of epilepsy. They looked to see the feasibility of triggering tDCS stimulation within 10 seconds of a detected EEG partial-onset seizure, and also a proof-of-principle determination of whether tDCS applied during this vulnerable period may be feasible to prevent the oncoming seizure. This study required 5 visits over the course of approximately 8 weeks. Each visit was separated by at least 2 weeks. Two of the visits had 24-hour EEG monitoring sessions. During these two sessions, the EEG and tDCS were hooked into a closed loop system, such that when seizure activity wasdetected, the tDCS was triggered to deliver stimulation. Subjects received active stimulation or sham stimulation sessions during the first 24-hour visit, and the opposite during the second. The subjects were randomized and counterbalanced. We have also added a healthy subjects cohort to assess the feasibility of the closed loop system. In order to test the proof-of-concept of this system, the experiment will focus on detecting and acting upon alpha- and beta-band changes traced in the EEG activity that is being recorded, and provide tDCS stimulation based upon those changes. We will enroll 6 subjects who will have 2 visits each. During these two visits subjects will be randomized to active or sham stimulation sessions and receive the opposite during their second visit.

Our primary objective is to compare two treatment options for prevention of seizures following a subarachnoid hemorrhage and determine if a short-course regimen of levetiracetam is as efficacious in the prevention of in-hospital seizures when compared to an extended course.

We wanted to find out if the early use of antipyretics is capable in preventing recurrences of febrile seizures. When a child has had his/her first febrile seizure, the parents were instructed to give him/her antipyretic medication every time when the child had a new episode of fever during two years.

The aim of the study was to assess the influence of volatile induction of general anaesthesia with sevoflurane using two different techniques and intravenous anaesthesia with propofol on the possible presence of epileptiform electroencephalograph patterns during the induction of general anaesthesia. We aimed to verify whether presence of epileptiform patterns (EPs) defined as polispikes (PS), rhytmic polispikes (RPS), periodic epileptiform discharges (PED) on Electroencephalographs (EEGs) influence the behaviour of values of the Bispectral Index (BIS), State (SE) and Response (RE), A-line Auto Regressive Index (AAI) derived from middle latency auditory evoked potentials (MLAEP) during the induction of general anaesthesia using abovementioned techniques and such variations may be useful in detection of presence of EPs.

In this study, the investigator aims to perform cortical stereo electroencephalogram (sEEG) recordings during simultaneous anterior nucleus of the thalamus (ANT) recording and stimulation to better understand the following: 1) how the ANT is involved in various seizure types; 2) which cortical regions are modulated by established ANT stimulation patterns; and 3) how novel ANT stimulation patterns modify epileptogenic cortical activity. Together, this knowledge will advance ANT deep brain stimulation (DBS) therapy by providing a physiologic basis for patient selection for ANT DBS, while identifying brain signals and stimulation patterns that can be used to develop novel methods for ANT DBS. Up to 15 adult patients (18 and older) who present to Duke Neurosurgery for routine seizure localization using sEEG will be asked to enroll in this pilot study of ANT recording and stimulation. In the course of surgical epilepsy treatment, patients routinely undergo surgical placement of sEEG electrodes for the purposes of seizure localization. During this procedure, 2 additional leads will be placed in the ANT. These patients remain hospitalized for 7-14 days after sEEG placement, during which time their seizure medications are tapered. Concurrent video monitoring is performed while continuous neural recordings are made through the sEEG electrodes. Additionally, continuous recordings will be performed through the electrodes placed in the thalamus. Periodically, standard intermittent high-frequency stimulation (130 Hz, 90-ms pulse width, and 2 mA intensity) will be performed with a 60-s on and a 300-s off cycle after surgery. These standard ANT stimulation parameters are employed clinically. Data will include the sEEG recordings marked for ANT stimulation, any side effects, medications, past medical history (PMH), and tests/procedures during the hospital stay. Risks involved are as described for the standard depth electrode surgery with the addition of the possible side effects from the stimulation which include sensations of numbness and tingling, and possibly increased seizure activity.

RATIONALE: Anticonvulsant drugs, such as levetiracetam, may help control seizures caused by brain metastases. PURPOSE: This clinical trial is studying the side effects and how well levetiracetam works in treating patients with seizures caused by brain metastases.

The objective of this study is to identify the following in adolescent epilepsy participants with partial-onset seizures (with or without secondary generalized seizures) or primary generalized Tonic-clonic seizures who receive long-term treatment with Fycompa: unknown adverse drug reactions (ADRs); occurrence of ADRs; factors that are likely to affect safety and efficacy; occurrence of dizziness, balance disorders, ataxia, muscle relaxation-related adverse events, and falls as priority investigation items; occurrence of psychiatric adverse events as priority investigation items (eg, aggression).

The study is intended to evaluate the impact of mobile application on management and knowledge acquisition in patients with epilepsy.

The primary purpose of this study is to investigate the effectiveness reflected by the retention rate of perampanel as the only add-on treatment in adult participants with primary generalized tonic-clonic (PGTC) or secondarily generalized tonic-clonic (SGTC) seizures based on focal or idiopathic generalized epilepsy in a non-interventional (observational) setting.

To study the efficacy and safety of single dose clonazepam compared with intermittent oral diazepam for prevention of recurrent febrile seizures in children who had three or more febrile seizures.
