The Role of Serotonin in Seizures
EpilepsySeizuresThis study will investigate the role that a brain chemical called serotonin plays in seizures. Serotonin, present naturally in the brain, helps transmit signals between nerve cells. Glucose is a sugar that is the main fuel of the brain. Studying these two chemicals may help explain why people with epilepsy get seizures and are more likely to be depressed. Healthy volunteers and patients 18 to 60 years of age who have epilepsy with or without depression and whose seizures are not controlled by medication may be eligible for this study. Candidates are screened with a review of their medical history, a physical examination and an electroencephalogram (EEG, brain wave recording). Participants undergo the following procedures: Positron emission tomography (PET) scans: The first of three PET scans measures brain blood flow and the activity at some of the brain serotonin receptors (the parts of brain cells to which serotonin attaches). A second scan measures the amount of serotonin transported between brain cells. A third scan measures glucose use. The PET scanner is shaped like a doughnut. The subject lies on a bed that slides in and out of the scanner with his or her head inside the opening. A special mask is fitted to the subject s head to help keep it still during the procedure so the images will be clear. For the first scan, catheters (plastic tubes) are placed in an arm vein to inject a radioactive substance and in an artery in the wrist to collect blood samples. The other two scans require only the catheter in the arm. Magnetic resonance imaging: This test uses a strong magnetic field and radio waves to obtain images of the brain. The scanner is a metal cylinder surrounded by a strong magnetic field. The subject lies on a table that can slide in and out of the cylinder. Most scans last between 45 and 90 minutes. Subjects wear earplugs to muffle loud knocking noises that occur during scanning. Psychological evaluation: Subjects are interviewed and fill out questionnaires to help study sadness and depression in epilepsy. Blood draw: Blood tests look for differences in genes between people with epilepsy who are depressed and those who are not.
Focal Electrically Administered Seizure Therapy for the Treatment of Depression
Treatment-Resistant DepressionThe purpose of this study is to determine the efficacy and any possible side effects of focal electrically administered seizure therapy (FEAST) as a treatment intervention for patients with recurrent and treatment resistant depression.
Levetiracetam Treatment of Neonatal Seizures: Safety and Efficacy Phase II Study
Neonatal SeizuresLEVNEONAT is a multicentre French clinical trials with the aim to develop new treatment strategies for the treatment of neonatal seizures using Levetiracetam. The purpose of this study is to determine the correct dosing, safety and efficacy for intravenous levetiracetam as first line treatment in term newborn babies with seizures in hypoxic-ischemic encephalopathy context. This new anticonvulsivant drug is a promising treatment for seizures in newborns.
Detection of Motor Seizures Using WBAN
SeizuresTonic-ClonicThis study aims to collect the motor movement data using sensors to detect Generalized Tonic Clonic Seizures . Wearable sensors similar to smart watches will be used to detect seizures. The proposed system will consist of 3-4 wearable wireless sensor worn on the hands and legs. The data from these sensors will be send to the clod and collected to a central hub for analysis and detection of GTC Seizures.
The Effect of Closed Suction System on the Incidence of Ventilator-associated Pneumonia.
Severe Traumatic Brain InjuryPancreatic Diseases4 moreThe investigators are suggesting that closed suction systems may reduce the risk of the ventilator - associated pneumoniae (VAP) and the contamination of the closest unanimated surfaces. In 2011 David et al. have shown that closed suction systems might reduce the incidence of the late VAP. Research team is thinking that preventive bundle with closed suction systems can prevent to onset of the VAP. All enrolled patients is randomizing into two groups: control group - conventional suctioning and research group - suctioning with closed suction system.
Cognitive Behavioural Therapy in Dissociative Seizures
Dissociative SeizuresThe purpose of this study is to determine whether adults with disoociative (psychogenic non-epileptic) seizures receiving cognitive behavioural therapy (CBT) show a greater reduction in seizures and health service use and greater improvement in employment status and overall psychosocial functioning than patients who receive standard care.
Usefulness of Sodium MRI in the Presurgical Assessment of Drug-resistant Partial Epilepsy
Epileptic SeizuresEpilepsy is a common disease affecting 0.5 to 1% of the general population. Epilepsies refractory to drug treatment lead to increased morbidity, mortality and high costs for public health (representing 75% of the costs associated with epilepsy is among the most costly diseases in Neurology). The only curative therapy is surgical removal or disconnection of the epileptogenic network. To do this, a comprehensive presurgical evaluation is essential to accurately define the location of the epileptogenic zone (EZ) and its relationship with the functional areas that must be preserved. This approach requires in some cases intracerebral EEG recordings. This latter technique, expensive and invasive, remains at present, the standard method in the location of the ZE. In this context, the development of non-invasive and inexpensive methods is a priority in the field. Moreover, many fundamental studies have shown changes in ion homeostasis including sodium associated with hyperexcitability related to epilepsy. The investigators team at CEMEREM, CHU Timone, specialized in the development and validation of innovative methods in MRI, has developed an in vivo sodium MRI acquisition and processing of data unique in France, capable of quantifying the intracerebral sodium concentration in three dimensions in a completely non-invasive and non-irradiating manner
EEG Cap for Identification of Non-Convulsive Status Epilepticus
Nonconvulsive Status EpilepticusSubclinical Seizure3 moreAltered mental status (AMS) is one of the most common reasons for inpatient neurology consultation. Non-convulsive status epilepticus (NCSE) is frequently on the differential diagnosis of the patient with AMS. NCSE becomes more refractory to treatment after one hour of seizure activity, making rapid identification and treatment of NCSE of great clinical importance. Currently, an electroencephalogram (EEG) technologist must be called in from home during non-workday hours in order to obtain a stat EEG. The investigators propose the time required for diagnosis of NCSE at Mayo Clinic can be significantly decreased with rapid placement of an EEG cap by the onsite neurology residents.
