Filter by:This study, conducted in children with typical or atypical "absence" epilepsy, will consist of noninvasive recording of the metabolic activity of the brain concomitantly with electroencephalographic recording during seizures without the need for any additional examination. This examination will be performed by combining near-infrared spectroscopy (NIRS) optical imaging and Electroencephalography (EEG) in a simultaneous High-Resolution (HR) recording. Surface electroencephalography (EEG) is a valuable tool to assess neuronal dysfunction from a functional point of view and is used in the routine follow-up of epileptic children. Optical imaging is a recent and promising medical imaging technique, which uses near-infrared light. This rapid, noninvasive and harmless quantitative technique can be easily used at the child's bedside or in the ward and provides metabolic information on brain functioning.
The investigators believe epilepsy alters the way the body controls blood pressure, heart rate and breathing, and these changes increase the risk of sudden unexpected death in patients with epilepsy (SUDEP). SUDEP-7 is a risk scoring tool which may correlate with these changes to the heart and blood vessels. This research study measures those differences which may help identify new markers to help predict those patients at greatest risk in the future.
This research study is examining the effects of Retraining and Control Therapy (ReACT; an intervention focused on changing behaviors and thoughts) for psychogenic non-epileptic seizures (PNES, episodes resembling epileptic seizures but with no medical explanation). Participants engage in 8 individual therapy sessions consisting of either cognitive behavioral therapy or supportive therapy. Healthy control participants also complete pre-questionnaires and two computer tasks.
The purpose of this study is to investigate the feasibility of using repetitive transcranial magnetic stimulation (rTMS) - a form of non-invasive brain stimulation - to decrease the frequency of psychogenic non-epileptic seizure (PNES) episodes in patients with PNES.
The purpose of this study is to examine whether the duration of treatment with phenobarbital has an impact on neurodevelopmental and epilepsy outcomes, as well as parent and family well-being, after neonatal seizures.
When providing amplification post-implantation to residual acoustic hearing in the implanted ear, the lower frequency boundary can be modified to minimize or avoid overlap between the frequencies coded through acoustic hearing and those presented through electrical stimulation. This boundary is termed the cross-over frequency (Fc) and the effect of modifying this parameter will be investigated in this study. To avoid the research being confounded by prior bias for a particular frequency allocation, the study will be conducted with newly implanted recipients. This study will also investigate whether tests which measure the ability to use low frequency hearing and objective measures can predict the preferred Fc and speech performance benefit.
The purpose of this study is to design and test the safety and feasibility of virtual reality technologies and experiences of egocentric avatar embodiment in the application of physical and cognitive behavior therapy in functional neurological symptom/conversion disorder. Investigators hypothesize that patients will safely use and accept this modality of treatment and will show evidence of a decrease in symptom frequency.
This study is geared toward characterizing the recovery of brain activity and cognitive function following treatments of electroconvulsive therapy and ketamine general anesthesia.
This is an open label prospective study of the impact on healthcare utilization of a surface Electromyography (sEMG) based seizure detection system for detecting Generalized Tonic-Clonic (GTC) Seizures.
The primary objective of this research is to evaluate the relationships between multiple data from cochlear implant (CI) adult users to and to estimate predictive models of their fitting parameters. In a group of patients, the Electrically-evoked Compound Action Potentials (ECAP) will be collected intra-operatively and the correlation with demographic data (deafness duration, age deafness onset, etiology, duration of cochlear implant use of CI), auditory performances and subjective measures used for implant fitting (hearing threshold and most comfortable level) will be calculated. In a second group of experienced users (more than 9months of use of their CI), ECAP and Electrically-evoked Auditory Brainstem Response (EABR) will be collected after 9 months of CI experience and after 12 months or more of use. Correlation analyzes with demographic data, performance and fitting parameters will be performed as well. Statistical predictive models for both fitting at the activation or in experienced users should be developed according to the correlation analysis. The secondary objective is to evaluate the effects of simultaneous stimulation on hearing performances. Simultaneous stimulations will be delivered in one ear (bimodal condition) in patients using an Electro-Acoustic Stimulation device (EAS) or in the two ears (binaural condition) for bilateral CI users. ECAP, EABR and speech perception will be measured and compared in the different conditions.
