Active clinical trials for "Epilepsy"

The purpose of this pilot study is to describe the relationship of regional cerebral oximetry and cytoximetry, measured using near-infrared spectroscopy, with seizure activity in the periictal period in children with epilepsy.

We are the missing link in clinical trials, connecting patients and researchers seamlessly and conveniently using a mobile health platform to advance medical research. We make it easy for patients to contribute to research for medical conditions that matter most to them, regardless of their location or ability to travel.

The purpose of this study is to identify genes responsible for epilepsy, brain malformations and disorders of human cognition.

The adolescent's search for self-discovery and identity in physical, psychosocial, cognitive and emotional areas may become more complex with epilepsy disease management. The adolescent's burden of treatment compliance may lead to poor adherence to the disease and worsen short- and long-term health outcomes. Disease self-management in epilepsy represents the processes required for disease knowledge, seizure control, medication adherence, increasing social support and quality of life, and reducing the negative effects of the disease. Educational training implemented in this period have an effect that increases motivation to gain skills to adapt to the disease. This model argues that knowledge is a basis for behaviour change, but it is not sufficient alone. However, it is argued that people will have the necessary behavioural skills when they are well informed and motivated for effective action. It is aimed to find a statistically significant difference from the scales (Epilepsy Knowledge Test for Adolescents, Seizure Self-Efficacy Status Scale in Children with Epilepsy, Multidimensional Perceived Level of Social Support Scale, Child's Attitude Towards His/her Disease Scale) at the end of the training of adolescents who received an 8-week training program.

Social cognition, which refers to the ability to interpret social information and behave accordingly in a social environment, is crucial in everyday life. But this ability has been shown to be altered in patients with epilepsy, especially in medial temporal lobe epilepsy, which leads to a deterioration in the patient's quality of life. However, the mechanisms of those deficiencies remain largely unknown. The Team objective is to achieve a structural and functional cartography of the social cognition network in 20 healthy subjects and 20 patients with drug-resistant medial temporal lobe epilepsy (before and one year after resective surgery of the epileptogenic focus). Social cognition deficiencies will be assessed using a specifically dedicated neuropsychological assessment validated in French (Batteries de Cognition Sociale BCS). Brain structural analyses will be performed on a 3-Tesla MRI (3T MRI), including an anatomical T1 sequence, a High Angular Resolution Diffusion Imaging (HARDI) to assess the morphology and macrostructural characteristics of long and short white matter tracts involved in social cognition, and quantitative MRI and Hybrid Diffusion Imaging (HYDI) to assess their microstructure. Functional connectivity will be assessed using an ultra-high-field 7-Tesla MRI (7T MRI), with acquisition in resting state and during specific social cognition tasks. Joint analysis of structural and functional connectivity will enable the team to assess the alterations of social cognition networks in patients with epilepsy and their reorganisations after epilepsy surgery.

Temporal Lobe Epilepsy (TLE) patients and healthy controls will undergo a night of sleep at the UC Davis Epilepsy Monitoring Unit (EMU) to characterize sleep architecture. A subset of TLE patients will be randomly assigned to an Acoustic Stimulation (AS) or SHAM stimulation night and return at least 7 days later for the other condition. Cognitive tests will be conducted 90 minutes prior to sleep (learning and immediate recall) and again 1 hour after awakening for 120 minutes (delayed recall and attention), while monitoring neural networks using functional Magnetic Resonance Imaging (fMRI).

The purpose of this study is to evaluate the feasibility, safety, and effects on anxiety of high intensity focused ultrasound ablation (FUSA) in patients suffering from treatment-refractory focal epilepsy and anxiety. FUSA is a non-invasive neurosurgical procedure that uses ultrasound waves, sent directly through the scalp and skull, to precisely target small abnormal areas of the brain. For this study, the targeted area of the brain is the anterior nucleus of the thalamus. This brain region may cause seizures and may also be involved in anxiety. The study will test if FUSA is safe and tolerated, and if it reduces anxiety and brain response to threat in patients with anxiety receiving the procedure for partial-onset epilepsy that is resistant to medications.

Epilepsy is a complex and chronic neurological disorder whose definition is not limited to seizures and also includes social, psychological, and cognitive consequences associated with this frequent condition. Despite good knowledge of the burden of cognitive deficits and psychosocial difficulties in epilepsy, there have been few attempts to address these issues through rehabilitation programs. The Rehabilitation of Cognition and Psychosocial well-being - A Better Life with Epilepsy (ReCaP-ABLE) study will consist of the creation and implementation of a psychological intervention in a randomized waitlist-controlled trial within a sample of adults with epilepsy. The trial is designed to provide novel evidence regarding 1) the effectiveness of a psychological-cognitive intervention in improving quality of life, objective and subjective cognitive functioning as well as reducing mental health symptomatology, 2) the target epilepsy population for which cognitive and psychosocial rehabilitation is most effective, and 3) the transfer effects of such an intervention. This interdisciplinary trial involving neurology and psychology specialists is set to guide evidence-based treatment for cognitive and psychological comorbidities that are prevalent in epilepsy but receive insufficient attention in clinical settings.

The present study is a 13 months pre-market open-label, prospective study for confirmation of continuous performance and safety of UNEEG EpiSight solution in subjects with uncontrolled epilepsy (indicated for EEG monitoring with the Implant) in which seizures are detectable in an area of the Implant. The surgical procedure, device satisfaction, and effectiveness of the UNEEG EpiSight solution will also be evaluated during the clinical investigation.

Epilepsy is a disabling neurological disease that affects tens of millions of people worldwide. Despite therapeutic advances, about a third of these patients suffer from treatment-resistant forms of epilepsy and still experience regular seizures.All seizures can last and lead to status epilepticus, which is a major neurological emergency. Epilepsy can also be accompanied with cognitive or psychiatric comorbidities. Reliable seizures count is an essential indicator for estimating the care quality and for optimizing treatment. Several studies have highlighted the difficulty for patients to keep a reliable seizure diary due for example to memory loss or perception alterations during crisis. Whatever the reasons, it has been observed that at least 50% of seizures are on average missed by patients. Seizure detection has been widely developed in recent decades and are generally based on physiological signs monitoring associated with biomarkers search and coupled with detection algorithms. Multimodal approaches, i.e. combining several sensors at the same time, are considered the most promising. Mobile or wearable non invasive devices, allowing an objective seizures documentation in daily life activities, appear to be of major interest for patients and care givers, in detecting and anticipating seizures occurence. This single-arm exploratory, multicenter study aims at assessing whether the use of such a non-invasive, wearable device can be useful in a real life setting in detecting seizures occurence through multimodal analysis of various parameters (heart rate, respiratory and accelerometry).
