About this study

The aim of the study is the examination of brain plasticity on verbal auditory hallucinations (AVH) after neuromodulation with fMRI (functional magnetic resonance imaging) neurofeedback. During the training of fMRI neurofeedback subjects are trained to regulate consciously the connectivity of areas which are associated with hallucinations.The aim is to improve perceived hallucinations' intensity in everyday life of the patients as well as investigating the impact of neurofeedback on resting-state networks in the brain. As control groups, control subjects without AVH and participants with AVH, but no psychiatric diagnosis will be included.

Read the detailed description

This study investigates the brain plasticity after neuromodulation with fMRI neurofeedback on verbal auditory hallucinations (AVH). The new technique of real-time fMRI enables subjects to influence their brain activity in certain areas based on neurofeedback. Current brain activity as measured by fMRI will be reported to the participants in real time via brain computer interface (BCI). Due to the identification of contingency between feedback and mental strategies subjects are able to control their own brain activity consciously. This provides the opportunity to control symptoms such as AVH. Neurofeedback has been tested on subjects with schizophrenia, leading to conscious control of circumscribed brain areas. Recent studies show that, in addition to the modulation of single areas, neurofeedback can also modulate connectivity between different areas. Thus, it is possible to regulate not only single brain regions but also whole networks.

AVH are a key symptom of schizophrenia. They limit social functions significantly and are resistant to the therapy with antipsychotics in 25 % of cases. AVH also occur in 6-15 % of the healthy population, without meeting any diagnostic criteria for schizophrenia or other psychiatric disorders. This study will perform a direct, not-invasive and selective modulation of networks underlying AVH and assess their neural, cognitive and emotional effects. The focus of this study is on the connectivity between auditory cortex and inferior frontal cortex. Various studies demonstrated that the auditory cortex exhibits an abnormal function in schizophrenia patients. It was shown that during AVH, auditory cortex (superior temporal lobe) and inferior frontal cortex synchronize spontaneously. These regions play an essential role in speech perception and processing. An increased synchronisation of these areas could lead to the development of AVH. This study will try to reduce frontotemporal connectivity to uncouple the regions. Increasing connectivity of both areas will serve as control condition and furthermore intensify the perceived control of the own brain activity and of the associated AVH. Thus, patients will learn which factors influence the appearance of their hallucinations.

What participants receive

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

  • fMRIProcedure or surgery

    Also called functional magnetic resonance imaging

    collection of functional brain data for 1 hour per day

  • NeurofeedbackBehavioural

    Task of the participants is to increase or decrease the connectivity between selected brain regions in double-blind, randomized order. After the regulation they will get a feedback about the regulation success. (Patients and controls with AVH: days 3 \& 4; controls without AVH: Days 2 \& 3)

  • PANASOther

    Also called Positive And Negative Affect Scales

    to assess the mood before and after the fMRI and after 1 week during a telephone interview

  • AVHRSOther

    Also called Auditory Vocal Hallucinations Rating Scale

    to assess the intensity and quality of the hallucinations before and after the fMRI and after 1 week during a telephone interview

  • SF36Other

    questionnaire about life quality after 1 week during a telephone interview

    Measured: 2 weeks

  2. Change in pathology (AVH)

    Auditory Vocal Hallucinations Rating Scale (AVHRS) as a measure of the intensity and quality of the hallucinations before and after the fMRI and after 1 week during a telephone interview

    Measured: 1 week after interventions

  3. number of patients and subjects with benefits from neurofeedback training

    Measured: 2 weeks

  4. change in brain activation

    fMRI as a measure before and after the following resting state

    Measured: 1 week after interventions

  5. Change in pathology (mood)

    Measured: 1 week after interventions

  6. Change in perceived quality of life

    SF36 questionnaire as a measure of the quality of life before and after the fMRI and after 1 week during a telephone interview

    Measured: 1 week after interventions

Questions about this trial

What is this clinical trial studying?

A study testing fMRI, Neurofeedback and PANAS in people with Hallucinations, Verbal Auditory, run by RWTH Aachen University at 1 site in Germany.

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 8 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 9 Jan 2020. 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 Germany. 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 self-control over neuronal connectivity (time frame: 1 week). 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 9 Jan 2020.
