About this study

In the case of psychotic disorders such as bipolar disorder or schizophrenia, attention dysfunction contribute, according to the theories of neuroscience, the development of mood disorders following disturbances in the interaction-care emotion. In this context, the general objective of this research project is to refine our understanding of the similarities and distinctions between bipolar and schizophrenic patients in the basic emotional information processing. Specifically, these are: 1) to better understand what level of basic emotional information processing both conditions differ or are comparable and in what sense and 2) estimate, in both pathologies, the specific influence of the nature of the task of processing emotional information. To answer these questions, the investigators have developed a protocol to specifically target different information processing channels playing on the nature of the spatial frequency content of emotional natural scenes. To estimate in both pathologies, the specific influence of the nature of the task on emotional processing, 3 types of tasks are proposed: 1) a simple task perception and 2) -3) two tasks whose categorization one focused on the emotional feelings of the individual and the other on the tendency to action. Both tasks categorization should involve more specifically the ventromedial prefrontal cortex (CPFVM) and the dorsolateral prefrontal cortex (DLPFC) respectively. All patient data will be compared with data from healthy control participants.

Main goals This research project generally aims to refine our understanding of the similarities and distinctions between bipolar and schizophrenic patients in emotional information processing.

Specifically, these are:

  1. better understand what level of emotional information processing both conditions differ or are comparable and in what direction
  2. assess specifically in both pathologies, emotional regulation deficits through the realization of different cognitive tasks when processing emotional information.

To answer these questions, the investigators developed an original protocol imaging functional magnetic resonance (fMRI) to specifically target different information processing channels playing on the nature of the spatial frequency content of emotional natural scenes (see Methods). emotional regulation deficits in both disorders will be addressed in part through here 3 types of tasks: 1) a simple task perception and 2) -3) two tasks categorization of which centered on the emotional feelings of the individual (task affective) and the tendency to action (motivational task). Both tasks categorization should involve more specifically the Prefrontal Cortex-Ventro Median (CPFVM) and Lateral Prefrontal Cortex-Dorso (DLPFC), respectively, distinguishing between the two categories of patients. All patient data will be compared to healthy control participants.

This project will also allow us to improve our knowledge in bipolar and schizophrenic patients compared with control subjects, i) on the brain structures of networks involved in emotional information processing and emotional regulation, ii) functional relationships still unclear between neural structures involved in both processes and iii) the nature of the information passing through these networks.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • behavioral and fMRIOther

    The experience will include 3 sessions. Each session will consist of the presentation of a pseudo-random sequence of 24 black and white images of negative emotional natural scenes, 24 positive emotional situations and 24 neutral emotional situations.

    • In the first session, participants will carry out an emotional assessment task: it will show at the end of each test his emotional feeling - pleasant, unpleasant or nothing - using a joystick.
    • In a second session, the participant will perform a motor task decision: it will show at the end of each test the tendency to action he would handle the situation actually using 3 buttons également- approach withdrawal or neither one nor the other.
    • In the third session, the participant will perform a simple visual perception task. To be comparable to the engine plane with the other sessions, a non-categorical motor task will be requested from participants.

Questions about this trial

What is this clinical trial studying?

A study testing behavioral and fMRI in people with Schizophrenia and Bipolar Disorder, run by University Hospital, Grenoble at 1 site 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 27 inclusion and 32 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: status not confirmed, as of the sponsor's last update on 11 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

Results are not available in the source record.

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

Contact VANESSA ESPIN (4 76 76 68 13 ext. +33 (0), VEspin@chu-grenoble.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Psychometric evaluation (time frame: 70 minutes). The study lists 5 primary outcomes in all. 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 11 Oct 2018.
