Filter by:Cognitive disorders are a major problem in patients with epilepsy. One hypothesis is that the anomalies EEGs (AIC) may be responsible for short periods of attentional fluctuations causing a reduction of intellectual efficiency of patients. In this project, we propose to evaluate the impact of AIC on cognitive performance, specifically on attentional performance (central parameter of cognitive functioning) through the use of a computerized cognitive test (called STABILO, detailed below after) to measure, with good temporal sampling, the level of attentional engagement of patients in relation to their EEG activity. The originality of this study lies in the synchronization of two examinations usually made independently (EEG and psychometric testing), respecting a precise temporal coupling. The aim is to provide clinicians with a tool to assess very quickly attentional fluctuations in epileptic patients, and to assess the potential impact of AIC on the occurrence of these changes, with possible therapeutic implications (treatment of AIC and / or specific treatment of attention deficit disorder). The main objective of this study is to assess whether the presence of AIC EEG can induce a weakening of attentional performance.
Epilepsy affects between 0.5 and 0.7% of the European population. Despite the availability of numerous drug treatments, one third of patients still have seizures, which are associated with significant cognitive and social complications and excess mortality. In these patients, surgical treatment to remove the epileptogenic zone (EZ), the region of the brain responsible for seizures, is the only approach that can allow control of the disease. However, before investigating this surgery, investigations have to answer two questions: (i) what is the location and extension of the EZ and (ii) what functional risks, both motor and cognitive, would represent the resection of this Cortical region? As it is a functional surgery, it is in fact inconceivable that the surgery will result in an over-handicap. For these reasons, all candidates for surgery benefit from a complete assessment including imaging examinations, a neuropsychological assessment and a long-term video-EEG recording to record seizures. Nevertheless, in some patients, this assessment does not give us a formal answer. In these subjects, it is then necessary to carry out a second step, consisting of an invasive exploration by implantation of intracerebral electrodes during a stereoencephalography (SEEG). Due to its temporal and spatial resolution, the SEEG allows, besides the precise determination of the EZ, to carry out a functional mapping of the cortical regions likely to be included in cortectomy. Conventionally, this mapping is carried out on the basis of the cortical electrical stimulations applied to the implanted electrodes. If this approach is very robust for exploring primary functions such as motor skills or language, it cannot be used to evaluate more complex cognitive tasks such as face recognition or attention Effective cognitive treatment on a daily basis. This has led to the development in recent years, in Lyon and Grenoble, of a complementary approach to cerebral stimulation: dynamic spectral imaging (ISD). Numerous experimental paradigms have demonstrated that the realization of a cognitive task associates with the generation within the cortical regions involved in its treatment of a particular cortical activity. This activity is characterized by oscillations of the cortical rhythm in high frequencies (> 30 Hz), called gamma activities. The ISD thus consists in mapping this gamma activity during various cognitive tasks, thus making it possible to study more widely the complexity of the cognitive functions. Correlations between gamma activity and cognitive tasks have so far been exclusively performed in the non-epileptic cortex explored at the periphery of the EA during SEEG. Nevertheless, the cortical oscillatory pattern study associated with a specific cognitive task within the EZ could better anticipate complex cognitive deficits that could be generated by the resection of a cortical region. The main objective of this project is to establish the predictive character of the gamma cortical oscillatory pattern associated with a specific cognitive task on the risk of occurrence of a cognitive disorder after surgery of epilepsy.
The purpose of the study is to evaluate the efficacy of brivaracetam (BRV) compared to placebo (PBO) as adjunctive treatment in subjects (>=16 to 80 years of age) with partial seizures with or without secondary generalization despite current treatment with 1 or 2 concomitant antiepileptic drugs (AEDs) and to assess the safety and tolerability of BRV in subjects >= 16 years to 80 years of age.
This is a non interventional prospective study. Centers will enroll adult participants with partial onset seizures with or without secondary generalisation for whom the clinician has decided to initiate eslicarbazepine acetate (ESL) as an adjunctive therapy or monotherapy prior to the decision to take part in this study. Participants to be enrolled into the study will receive ESL either as an adjunctive therapy to one baseline antiepileptic drug (AED) or to at least two baseline AEDs or as monotherapy. Participants will be seen at baseline and at a follow-up visit after approximately 6 months to assess retention, efficacy, tolerability, quality of life (optional), and cognitive performances (optional).
This study will measure the engagement of people with epilepsy in a mobile phone based messaging platform as well as understand if there is an impact on their self-management
Numerous studies over the past decade have shown without any doubt that there is a higher mortality risk in patients with epilepsy than in the general population. The cause of death may be related to the cause of epilepsy, being directly related to a seizure (status epilepticus or sudden unexpected death in epilepsy; SUDEP), a consequence of seizures (accidents, etc), other associated pathologies (cancer, cardiovascular disease, ischemic heart disease, pneumonia, etc) or an associated disorder (depression or suicide). A SUDEP is defined as a sudden, non-traumatic, unexpected death in a patient with epilepsy, not necessarily in the presence of witnesses, that is not due to drowning, with or without evidence of a seizure, excluding documented status epilepticus and in which a post-mortem autopsy reveals no anatomical or toxicological cause of death. Little is known about SUDEP and its mechanisms and risk factors. This epidemiological study is based on the RSME. The Main objective of this study to identify risk factors of SUDEP, in particular night-time supervision and the risks associated with anti-epileptic drugs including compliance and drug interactions.
Children with refractory epilepsy who are candidates for a treatment with vagus nerve stimulation will be prospectively randomized into 2 arms. Vagus nerve stimulation parameters are programmed and adjusted during outpatient clinic visits, within the normal clinical practice.
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: 1. unknown adverse drug reactions (ADRs); 2. occurrence of ADRs; 3. factors that are likely to affect safety and efficacy; 4. occurrence of dizziness, balance disorders, ataxia, muscle relaxation-related adverse events, and falls as priority investigation items; 5. occurrence of psychiatric adverse events as priority investigation items (eg, aggression).

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.
