Clinical Trial Summary
The purpose of this study is to determine whether real-time fMRI feedback is effective in the
treatment of aggressive behavior problems in adolescents with high callous unemotional traits
when compared to treatment as usual.
Description:
In this study, which is part of the European research project MATRICS (Multidisciplinary
Approaches to Translational Research), the investigators focus on testing an innovative,
non-pharmacological therapeutic approach for adolescents with a specific, difficult to treat
subtype of aggressive behavior problems. Participants will be trained to acquire control over
their own physiological parameters, in case of this study the activation of certain brain
areas. While trying to control these parameters, participants get direct continuous feedback
about their physiological state and its changes, and are rewarded for successful
manipulation. Biofeedback methods are currently used to treat patients with a variety of
psychiatric disorders such as attention-deficit/hyperactivity disorder (ADHD).
Here, real-time functional magnetic resonance imaging (rt-fMRI) feedback will be used, where
participants will get feedback about activation levels and patterns from brain regions
associated with emotion processing (amygdala/insula) in almost real time while lying in a
magnetic resonance tomograph scanner.
Investigators will focus on the following questions concerning the effectiveness of this
treatment approach:
1. Can participants gain increasing control over the activation of defined brain regions
through real-time fMRI training?
2. Which short- and longer term consequences can be expected from improved self control
over brain activation upon aggressive and antisocial behavior problems?
Before the training, all participants will undergo an extensive pre-treatment assessment as
part of the characterization and subtyping of aggression within the large multicenter
subtyping studies (EU-Aggressotype and EU-MATRICS). The assessment includes clinical and
psychometric measures, neuropsychological testing, fMRI (3 active tasks + resting state), MRS
(anterior cingulate cortex (ACC) and insula) and diffusion tensor imaging (DTI) as well as
biosampling (blood/saliva for genetics/epigenetics/hormones). Comparison with a typically
developing (TD) control group receiving no intervention will allow to interpret changes in
terms of normalization or compensation.
After completion of this pretest, subjects meeting the inclusion criteria for the rt-fMRI
treatment study will be randomly assigned to two different treatment arms, either to the
experimental fMRI real-time feedback condition or to the comparator condition with treatment
as usual (TAU) lasting 10 weeks. Subjects assigned to the experimental condition will receive
10 sessions (1/week) of real-time fMRI feedback of amygdala and/or insula activation (based
on activation patterns during pre-training assessment). Each training will last about 1 1/2
hours and consist of 3 experimental blocks, including feedback- and transfer trials. Video
clips of emotional and aggressive interpersonal interactions will partly be used to enrich
feedback conditions with naturalistic, virtual reality type displays. Heart rate and
electrodermal activity will be recorded simultaneously during the sessions. Subjects in the
comparator TAU arm will receive several sessions of psychoeducation and counseling with their
parents/caregivers or group training over the 10 weeks.
After completion of either the training or the TAU, subjects will undergo post-treatment
assessment, repeating the teachers and parents reports on behavioral measures, as well as the
neuropsychological testing, fMRI and MRS. A follow-up assessment will take place 6 months
after the end of the treatment phase and will comprise only parents and teachers reports on
behavioral measures.
