About this study

Official title: Spectral Dynamic Imaging of Cognitive Functions in Epileptic Patients Explored

This prospective research aims to develop the use of Spectral Imaging in addition Dynamics of cortical electrical stimulation to identify major anatomical and functional networks in epileptic patients candidates for surgery and explored by stereoencephalography, to minimize risk of post-surgical cognitive deficits.

Read the detailed description

Cognitive deficits after epilepsy surgery are poorly known particularly because the tools used to evaluate them. In addition, the prevention of certain postoperative deficits, is extremely difficult because of the lack of robust markers to anticipate. The various examinations conventionally used for this purpose (neuropsychological testing, functional MRI and cortical stimulation) does indeed provide insufficient information or difficult to interpret, so the development of improved methods appears as an imperative in the field of the epilepsy surgery.

SID appears as such particularly adapted to the case of epileptic patients explored SEEG to provide individualized cognitive map millimeter thereof without requiring, for additional invasive act, or risk of inducing unintended crisis. In practice, this clinical research project should lead to the definition of several simple cognitive tasks which, together, could be achieved by each volunteer patient in two or three hours, and then analyzed in a similar time to provide fast, even the patient is still explored SEEG and even before cortical electrical stimulation, a list of brain regions involved in most major cognitive functions.

Questions about this trial

What is this clinical trial studying?

A study testing Spectral Dynamic Imaging, Hybride electrode and Macro electrode in people with Epilepsy, run by University Hospital, Grenoble at 2 sites in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Functional brain mapping procedure using the EEG signal intracranial to minimize the risk of cognitive deficits associated with resection of the epileptogenic zone. (time frame: 3 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Oct 2017.
