Prevalence of Cognitive Disorders in Newly Diagnosed Epilepsy

A prospective prevalence study recorded that up to 50% of adult patients with newly diagnosed epilepsy had at least one cognitive impairment before initiation of antiepileptic drug (AED). Multiple factors exist and interact in the same patient. Cognitive impairments may affect psychiatric (loss of self-esteem, anxiety, depression) and social status (e.g., vocational aptitude, educational). These factors in turn influence cognitive abilities in a triangular and bidirectional relationship. In addition, the type of epilepsy, development in childhood or cerebral ageing, antiepileptic treatments (AED, surgery) and etiology also have an impact on cognitive performances. The burden of these factors differs from patient to another and must be determined individually. Longitudinal follow-up seems to be crucial because it will allow us to highlight the change in the cognitive profile of newly diagnosed patients over time. The main objective is to compare the prevalence of cognitive impairment in patients with newly diagnosed epilepsy prior to the initiation of AED with healthy subjects matched on age, sex, manual laterality and socio-educational level. But also to compare the longitudinal evolution of the cognitive profile of patients with healthy controls (0 to 10 years) to determine, among the age of onset seizures, their etiology, the syndrome, the sex, the socio-educational level and the cognitive reserve, which one are related to the severity of cognitive disorders.

READYorNot[TM] Brain-Based Disabilities Trial

The purpose of this study is to find out if there is a benefit to using the MyREADY Transition[TM] BBD App for brain-based disabilities, compared to not using it. To do this, some of the participants in this study will use the MyREADY Transition[TM] BBD App and others will not use the App. Everyone will continue to get the same care they have been getting (their usual care). The study team wants to see how youth will use the MyREADY Transition[TM] BBD App as they are getting ready to leave the children's hospital or children's treatment centre. And, they want to see if it will help youth to be knowledgeable about their own health. The study team hopes to see youth taking steps to develop the skills so they become better managers of their health. For example, this would include knowing about their medication or knowing when to ask for help from parents/caregivers and health care providers.

Stimulation of Sleep in Patients With Epilepsy

Sleep slow waves (SSW) and the pathophysiological mechanisms of spike generation in patients with epilepsy are tightly linked. SSW are cortically generated oscillations (~1 Hz) alternating between a hyperpolarized down-state (neuronal silence) and a depolarized up-state (neuronal firing). It has been shown experimentally that with increasing synchrony of slow neuronal oscillations, spike wave occurrence is facilitated. Auditory stimulation applied in correspondence to the SSW "up-phase" may increase the amplitude of the following SSW. Contrarywise, tones applied at the SSW "down-phase" may have a disruptive effect on SSW. Participants: Patients with epilepsy with epileptic discharges in their sleep EEG, as well as healthy controls Objective: Characterizing the effects of down-phase-targeted auditory stimulation on behavior and sleep EEG characteristics and determine whether the changes in sleep EEG characteristics are associated with the changes in behavior and wake EEG characteristics.

Direct Cortical Measurement of the Intensity and Pattern of Current Flow Produced by TDCS

The primary study objective is to measure the electrical fields evoked by tDCS using subjects who have implanted intracranial electrodes as part of their evaluation for epilepsy surgery. The measurements obtained in these subjects and their brain MRI will be employed to validate existing mathematical models. In the future, these refined models can be used to target tDCS to predetermined brain regions in healthy and subjects and patient populations. As described above in the safety section, the intensities of stimulation applied in this project are not expected to produce changes in brain function, are below intensities commonly applied in clinical trials, and fall well below safety limits suggested by animal studies.

Start: November 2013

Neurophysiologically Based Brain State Tracking and Modulation in Focal Epilepsy

Researchers are trying to determine if tracking seizure occurrence, seizure probability, behavioral state, cognition, and mood can be achieved using an implantable brain sensing and stimulation device (Medtronic RC+S Summit) coupled to an external, handheld, patient assistant device (PAD) with capability for patient interaction (patient data input). The system (RC+S & PAD) provides intracranial EEG (iEEG) sensing, electrical brain stimulation, and machine learning algorithms running on the RC+S and PAD that will be coupled with electrical brain stimulation (EBS) to prevent seizures and improve quality of life in patients with epilepsy.

Presurgical Motor Mapping With Transcranial Magnetic Stimulation (TMS)

The aim of the study is to examine the degree of concordance between presurgical neuronavigation guided TMS (nTMS) and direct cortical stimulation (DCS) in identifying hand motor cortex in adults undergoing epilepsy surgery. Navigated transcranial magnet stimulation (nTMS), MagStim RapidStim2 Magnetic stimulation will be delivered to hand primary motor cortex, with positive and negative functional sites determined through surface electromyography (EMG). The study will involve patients ages 12-60 years, with planned neurosurgery involving implantation of intracranial subdural electrodes including over the precentral gyrus. Navigated transcranial magnet stimulation (nTMS), MagStim RapidStim2 Magnetic stimulation will be delivered to hand primary motor cortex, with positive and negative functional sites determined through surface electromyography (EMG). The primary outcome measure will be spatial correlation between topographic maps of hand motor representation obtained through nTMS compared to direct, extra-operative cortical stimulation performed as part of routine clinical care. A secondary outcome measure will be safety and tolerability of TMS in the epilepsy patients.

Mindfulness Meditation for Epilepsy

In one-third of epileptic patients treated in France, seizures persist despite drug treatment. These so-called "refractory" epilepsies are among the most severe. Only a minority of patients with refractory epilepsy can undergo surgery. The other options available are based on brain or vagus nerve stimulation interventions which clinical effectiveness is still being studied. Alternative therapies are needed both to decrease the frequency of patients' seizures and to improve their quality of life. The practice of mindfulness meditation has recently been included in the recommendations of the International League Against Epilepsy in order to alleviate anxiety or depression comorbid symptoms. This study falls within this framework by targeting two aspects of the pathology.
