About this study

Official title: Effects of Mindfulness Practice on the Neural Circuitry of Conditioned Fear Extinction in Healthy Participants

It is well-established that the practice of mindfulness meditation leads to improvements in mental health and well-being and the cultivation of positive emotions. However, the neural mechanisms of these improvements are largely unknown. A few recent studies suggest that mindfulness meditation impacts the structure and function of the ventromedial prefrontal cortex, the hippocampus, and the amygdala. Interestingly, recent studies have shown that these regions are part of a brain circuit that is critical for the extinction of conditioned fear responses, and for the retention of fear extinction memory. Building on the overlap of these regions and on conceptual considerations, the project investigates whether mindfulness meditation could influence one's capacity to retain the memory of fear extinction. Meditation-naïve participants will be randomized to either a mindfulness-meditation based training or an active control training that controls for all mindfulness-unspecific components. Participants will undergo a fear conditioning, extinction and extinction recall protocol in an MRI scanner before and after the trainings. We hypothesize that participants who have practiced mindfulness meditation will show greater improvements in fear extinction memory after the course, and that these improvements will be correlated with anatomical and functional changes in the brain regions of interest. Improvements in fear extinction memory will also be related to improvements in self-reported psychological well-being. Merging the fields of an ancient spiritual tradition and a fundamental learning mechanism, the project investigates the underlying neural mechanisms of a practice for the enhancement of mental health and well-being.

What is being measured

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

  1. change in MRI data

    We will measure the change in functional MRI during fear conditioning, extinction, and extinction retention memory pre to post intervention. Furthermore, we will measure changes in structural MRI data, DTI data and resting state fMRI data.

    Measured: pre and post intervention or wait period; first set of MRIs within 3 weeks before the course, second set of MRIs within 3 weeks after course; MRIs will take 1.5 hours each and will occur on 2 consecutive days

Secondary outcomes (1)
  1. change in well-being

    questionnaire data will also be collected pre and post the intervention / wait period; change in the scores will be assessed

    Measured: pre and post intervention or waitlist period; collected when the MRIs take place; will take about one hour each

Questions about this trial

What is this clinical trial studying?

A study testing Mindfulness-Based Stress Reduction course in people with Healthy Individuals and Highly Stressed, run by Massachusetts General Hospital at 1 site in United States.

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 1 inclusion and 4 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 7 May 2012. 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 United States. 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?

change in MRI data (time frame: pre and post intervention or wait period; first set of MRIs within 3 weeks before the course, second set of MRIs within 3 weeks after course; MRIs will take 1.5 hours each and will occur on 2 consecutive days). 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 NCT01320969, 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 7 May 2012.
