Trial summary

Epilepsy is a frequent neurological disorder with about a third of patients having seizures despite treatment. At least some of these seizures can be linked to a low compliance and therapy adherence of patients. Read more about this study

About this study

Epilepsy is a frequent neurological disorder with about a third of patients having seizures despite treatment. At least some of these seizures can be linked to a low compliance and therapy adherence of patients. Compliance is defined as "the extent to which a person's behavior (in terms of taking medication, following diets, or executing life style changes) coincides with medical or health advice". Therapy adherence of patients suffering from epilepsy is low with reported rates between 30 and 50%, although adherence to anticonvulsive drug therapy is critical for effective disease management and low therapy adherence is associated to higher mortality in epilepsy. The reasons for low therapy adherence are still a matter of research. Some known factors influencing compliance in epilepsy are related to its chronic nature, but others seem to lie in a complex interaction between psychiatric comorbidity and an impairment of neural systems underlying behavior. Furthermore, therapy adherence rests a variable difficult to measure, especially in epileptic patients where classical tools such as questionnaires and electronic monitoring devices have been shown to be imprecise. It has been argued that the term 'compliance' should be replaced by 'co-operative behavior' and non-compliance can therefore be interpreted as troubled co-operative behavior. This behavioral approach offers the potential of using tools and methods of the latest developments in behavioral neuroscience. Neuroeconomics, a scientific field on the border of psychology, economics and neuroscience, has used economic game paradigms in order to operationalize cooperative behavior and to identify several brain areas by functional brain imaging that have been linked to social co-operative behavior. The majority of these brain areas are located in the frontal cortex [ventromedial frontal/orbitofrontal cortex, and rostral anterior cingulate cortex. Epilepsies originating in the frontal lobe are subsumed under the term "frontal lobe epilepsy" (FLE) and represent 20-30% of all partial seizures and 25% of all refractory focal epilepsies referred to epilepsy surgery.

The investigator's project plans to study compliance and cooperative behavior of patients suffering from frontal lobe epilepsies through a neuroeconomic approach by (1) comparing the behavior of these patients in the prisoners' dilemma game to the behavior of age-, gender-, and education-matched healthy controls, (2) correlation of game behavior to brain activation measured by functional magnetic resonance imaging in both patients and healthy controls and (3) studying the link between cooperative behavior to compliance captured by pill counts and questionnaires.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Social cooperative behavior as measured by the prisoners' dilemma game

    The prisoners' dilemma game (PDG; Trivers, 1971) is a well-studied game derived from economic game theory that has been used extensively to quantify and study cooperative behavior. The two players in the game can choose between two moves, either "co-operate" or "defect". If both players co-operate, they both receive the reward R. If one player defects, while the other one co-operates, then the defector receives the payoff T while the co-operative player receives the payoff S. If both players defect, they both receive the payoff P. (T > R > P > S).

    Measured: 1 day

Secondary outcomes (6)
  1. Blood-oxygen-level dependent signal during the Prisoners' dilemma game

    Whole brain analysis of correlation between behavior in the PDG (prisoners' dilemma game) and brain activation as measured by the BOLD (blood-oxygen-level dependent) signal captured through functional MRI as well as group differences between patients and controls.

    Measured: 1 day

  2. Neuropsychological profile

    analysis of neuropsychological testing of (working) memory, attention, theory-of-mind and executive functions.

    Measured: 1 day

  3. Pill counts

    Pills taken and not-taken during the study period will be counted as a variable of therapy adherence.

    Measured: 1 day

  4. Scores acquired by questionnaire

    Several questionnaires to cover beliefs about therapy adherence will be applied.

    Measured: 1 day

  5. Scores acquired by questionnaire

    questionnaire to cover beliefs about medicines will be applied

    Measured: 1 day

  6. Scores acquired by questionnaire

    questionnaire to cover beliefs about trust towards physicians and medications will be applied

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

A study testing functional magnetic resonance imaging exam in people with Frontal Lobe Epilepsies, run by Hospices Civils de Lyon 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 15 inclusion and 19 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 4 Sep 2025. 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?

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?

Social cooperative behavior as measured by the prisoners' dilemma game (time frame: 1 day). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02441478, which also lists 1 linked publication.

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 4 Sep 2025.
