Knowing the impact that the use of ESL as adjunctive treatment of partial epilepsy has on cardiovascular risk factors measured by biochemical and ultrasound parameters compared with enzyme-inducing AEDs.
Sudden unexpected death in epilepsy (SUDEP) is the main concern of professionals and patient associations involved in epilepsy. These represent a priority for the Ligue Française Contre l'Epilepsie (LFCE). The SUDEP affect primarily young adults, between 18 and 40 years, suffering from epilepsy uncontrolled by medication. In this population of close to 100,000 people in France, the incidence of SUDEP is estimated at 0.5%, or nearly 500 deaths per year. It is clear that the majority of these deaths occur in the immediate consequences of a crisis.. Investigators suppose that a causal link exists between the occurrence of a SUDEP and a per / post-critic decline of SpO2 below 80 % (75 % of cases, 20 % of controls).The constitution of a cohort of 1500 patients clinically well described and a national database will allow other ambitious projects in a speciality where French centres benefit from a unique knowledge, recognized by their foreign colleagues, but underexploited to date. The LFCE (Ligue Française Contre l'Epilepsie) is developing structuring actions to facilitate such exploratory studies for the next two years. The high death rate which characterizes the drug-resistant partial epilepsies and, in particular, Sudden Unexpected Deaths in Epilepsy (SUDEP) represents the main axis of research for the Ligue Française Contre l'Epilepsie (LFCE) as well as for associations of epileptic patients and the European representatives of the international league against epilepsy ( ILAE). Today, SUDEP occurrences cannot be anticipated. Patients can't be warned against SUDEP. Although the SUDEP physiopathology remains uncertain, many elements plead for the essential role of a per-and post-critic apnea (central or obstructive). Investigators observe that about 20 % of the patients admitted in a EEG-video monitoring - EEG unit for recording their crisis are going to present experience an per / post-critic severe apnea, severe per / post-critic enough to have induce a SpO2 < 80 % decrease. However, today, no study has estimated the link relation between the arisen occurrence of such apneas and the later risk of SUDEP.
Sudden unexpected death in epilepsy (SUDEP) is a tragic outcome of seizure disorders that primarily affect young adults suffering from refractory epilepsy. In this population, SUDEP incidence is estimated at 0.5%. While the mechanisms of SUDEP are not completely understood, it appears that the majority of such death occurs in the immediate aftermath of a general tonic-clonic seizure. There is currently no validated preventive treatment for SUDEP. Some evidence suggest that modulation of the serotoninergic tone, and more specifically selective serotonin recapture inhibitor (SSRI) such as fluoxetine, might prevent SUDEP. Indeed, fluoxetine prevents seizure-induced lethal central apneas in DBA/2 and DBA/1 mice, one of the few animal models of SUDEP. Furthermore, serotoninergic bulbar nuclei are known to play a major role in the control of breathing, especially during sleep and in response to repeated hypoxia. In patients with epilepsy undergoing in-hospital video-EEG monitoring, about one third of seizures are associated with decrease in SpO2 <90%, an abnormality suspected to represent a risk factor of SUDEP. In a retrospective uncontrolled study, patients treated with SSRIs displayed less frequent ictal/post-ictal hypoxemia than patients not taking SSRIs. The investigators project aimed at testing whether fluoxetine can reduce the risk of ictal/post-ictal hypoxemia by performing a double-blind, randomized, placebo-controlled trial in patients undergoing video-EEG monitoring as part of the pre-surgical evaluation of their focal drug-resistant epilepsy.
Epilepsy is a multifaceted disorder and a major public health problem. In addition to recurrent and unpredictable seizures, abnormalities in psychiatric status, cognition and social-adaptive behaviors are potential major sources of disability in children and adults with epilepsy disorders. Recent studies have unequivocally documented raised psychiatric comorbidities in children with epilepsy, particularly emotional regulation disorders such as depression and anxiety, as compared to both the general population and the children with other medical disorders, neurological and non-neurological. A prevalence of 12% to 35% has been reported, compared to 3-8% in the general population. Major advances have begun to uncover the potential mediators of emotional regulation disorders and social comorbidities in epilepsy, but important gaps remain in the early detection, treatment and prevention of these disorders. A very small number of investigations have examined children with epilepsy at or near the time of diagnosis. This is a time during which the effects of chronic epilepsy, potential averse social effects of epilepsy, and other complicating aetiological effects are minimized. Epilepsy syndromes provide a useful framework for considering the risk and type of emotional dysregulation comorbidities. But variability within and across syndromes needs to be taken into account thus requiring a strict phenotyping by specialists in the filed of pediatric epileptology. Retrospective studies, usually including patients with chronic epilepsies and suffering from a mixed spectrum of epilepsy syndromes introduce biases leading to rather disparate findings. Are such disorders the result of common physiopathological mechanisms, which precede the development of the epilepsy? The link between an underlying brain disorder and psychiatric comorbidities has emerged in recent literature, with evidence based on studies in adults, suggesting bidirectional relations between epilepsy and neurobehavioural comorbidities. Emotional regulation disorders can follow the onset of epilepsy, but they can also precede it, thus serving as a possible risk factor. The clinical implication of such a bidirectional association is that neurobehavioural comorbidities might be present at diagnosis and even before epilepsy onset. There is a need for greater understanding of the causes of these conditions in younger people. The degree to which specific epilepsy syndromes are associated with the relative risk of emotional dysregulation disorders in children with new- or recent-onset (within six months prior to enrolment) has rarely been comprehensively examined and represents the focus of the current investigation. The investigators study will be based on a prospectively recruited cohort of 280 children/adolescents with recently diagnosed epilepsy. All participating centres dispose of the necessary competences for a precise diagnosis of the epilepsy syndromes and the tools for a per case appropriate aetiology screening. Following a first seizure children are usually first examined at hospital based emergency departments. Prompt referral to the epilepsy teams participating at the present study will significantly reduce the population biases and shortcuts encountered in studies that recruited patients with chronic epilepsy followed in tertiary care epilepsy units. The investigators expect their results to provide a greater understanding of both the shared and the unique features of emotional regulation disorders, in relation to specific epilepsy categories defined on the basis of the underlying physiopathological mechanisms. Such knowledge will also assist clinicians and families in the planning of both diagnosis and management resources.
The purpose of this study is to better define the potential molecular and anti-inflammatory changes induced by the modified Atkins diet in the brains of patients with treatment resistant epilepsy. The investigators plan to enroll 30 subjects overall in this study to compare serologic and brain tissue specimens. At NYU, investigators plan to enroll 20 subjects; an estimated ten (10) subjects will consume a modified Atkins diet for 3-4 weeks prior to surgery and an estimated ten (10) subjects will consume a non-modified, higher carbohydrate diet. Investigators at Saint Barnabas Medical Center plan to enroll 10 subjects in this study to compare serologic and brain tissue specimens. Approximately five (5) subjects will consume a modified Atkins diet for 3-4 weeks prior to surgery and five (5) subjects will consume a non-modified, higher carbohydrate diet. Blood and brain tissue specimens will be obtained at the time of surgery and will be compared. The goal of this study is to identify whether or not there are changes in neuroinflammation or neuroexcitability in the human brain induced by the modified Atkins diet.
This trial consists of 2 parts: a double-blinded phase and an open-label extension phase. The blinded phase only will be described in this record. Participants were randomized in a 4:1 ratio to receive GWP42003-P or matching placebo.
This study consisted of 2 parts: a double-blind (DB) phase and an open-label extension (OLE) phase. Only the OLE phase is described in this record. The OLE phase was a safety study. All participants received GWP42003-P initially titrated to 20 milligrams (mg)/kilograms (kg)/day; however, investigators subsequently decreased or increased the participant's dose to a maximum of 30 mg/kg/day (no minimum).
PF-06372865 in subjects with photosensitive epilepsy
Background: Close relationship exists between sleep slow wave (SSW) and the generation of spike wave in NREM-sleep. SSW are cortically generated oscillations alternating between excitatory depolarization ("Up-phase" of the SSW) and inhibitory hyperpolarization ("Down-phase" of the SSW). It has been shown experimentally that with increasing synchrony of slow neuronal oscillations SSW turn into spike waves. Acoustic pulses applied in correspondence to the SSW "Up-phase" enhance the amplitude of the subsequent SSW. Conversely, tones delivered at the SSW "Downphase" have a disruptive effect on the following SSW. Participants: Patients with epilepsy and spike waves in NREM-sleep. Objective: Modification of spike wave frequency, amplitude and spreading during NREM sleep by acoustic pulses applied at the "Up-" or "Down-phase" of SSW.
