Clinical Trial Summary

The aim of the study is to compare the effects of the self-regulation (neurofeedback) of the fMRI signal of the prefrontal cortex in depression to ones of more conventional non-pharmacological treatment, primarily, psychotherapy.

Description:

The study was devoted to the neural, clinical, and psychological effects of the rt-fMRI neurofeedback for mild/moderate depression. Recruited unmedicated patients suffering from depression were assigned either to the fMRI neurofeedback (8 sessions of the left prefrontal cortex activity regulation) or to the active control group, i.e., a double dosage of cognitive-behavioral treatment or EEG neurofeedback (preliminary aborted). Depression symptoms were measured at baseline, at mid-treatment, and at post-treatment points. Some inventories of depression and related traits were also given. In the rt-fMRI group, self-regulation learning was also estimated by means of the fMRI signal change.

Related Conditions & MeSH terms

• Depression
• Depression Mild
• Depression Moderate
• Depressive Disorder

Intervention

Behavioral:
• Real-time fMRI neurofeedback (rt-fMRI NFB)
Real-time fMRI neurofeedback targeting control of the left medial prefrontal cortex. Participants continuously received visual feedback on the level of activity within the 2D region of interest corrected to the whole-slice brain volume activity. Up- and downregulation blocks were switched for better control.
• ?ognitive behavioral therapy (CBT)
A combination of individual and small-group cognitive behavioral therapy by an experienced medical psychologist and a psychiatrist.
• EEG neurofeedback (EEG NFB)
EEG neurofeedback targeting frontal alpha asymmetry index. Participants continuously received visual feedback on their frontal alpha asymmetry index. Up-regulation condition only was utilized.
