About this study

Official title: The DiSCoVeR Project: Examining the Synergistic Effects of a Cognitive Control Videogame and a Self-administered Non-invasive Brain Stimulation on Alleviating Depression

Major depressive disorder (MDD) is a common, recurrent, and frequent chronic disorder. Treatment is often challenging; up to 40% of patients do not benefit sufficiently from existing antidepressant interventions including trials of medication and psychotherapy. Up to 25% of patients manifest a chronic course of illness, resulting in a need for additional treatment options.

The DiSCoVeR trial is a multi-site, double-blind, sham-controlled, proof-of concept randomized controlled trial (RCT). The study aims to investigate the feasibility and efficacy of an innovative, combined treatment approach, incorporating transcranial direct current stimulation (tDCS) along with a custom-made video game designed to enhance cognitive control in patients with major depressive disorder (MDD).

Patients diagnosis of MDD receive a 6-weeks treatment with prefrontal tDCS along with an active videogame or sham tDCS + sham game for 6 weeks. Follow-up per patient is 6 weeks following treatment. Before, during and after the treatment period different assessment scales will be conducted to record neuropsychological features and the course of symptom changes.

Read the detailed description

Major Depressive Disorder (MDD) is a prevalent, seriously impairing, and often recurrent mental disorder. It has been ranked as a leading cause of disability worldwide by the World Health Organization (WHO) as measured by years lived with disability.

A considerable number of patients with MDD experience a chronic course of illness and approximately one third of MDD patients do not respond sufficiently to pharmacological treatment, calling for treatment alternatives.

Non-invasive brain stimulation techniques (NIBS) such as tDCS targeting prefrontal cortical areas have emerged as a safe, promising, and cost-effective alternative to traditional treatment options in patients with MDD.

This study focuses not only on an overall reduction of depressive symptoms, but also an alleviation of cognitive control deficits in particular, since patients with MDD often suffer from cognitive control deficits. tDCS has been shown to directly modulate cognitive control functions in healthy participants and in depressed patients. Another approach to directly modulate cognitive control functions is cognitive control training.

In the present study, an engaging and captivating cognitive control training designed as an action video game will be employed. The primary objective is to test the feasibility and efficacy of this innovative, combined treatment approach for self application, concurrently applying both interventions (tDCS + cognitive control training) in patients suffering from MDD. Additionally, participants have the opportunity to choose to take part in two adjunctive assessments: a biological assessment which includes salivary samples and a multimodal imaging paradigm (structural and functional sequences, including an interleaved TMS-fMRI paradigm).

What is being measured

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

  1. Feasibility of treatment

    Feasibility is met if a patient will complete 20 sessions per protocol with a probability of more than 50.00%.Completion per protocol is achieved, if the patient completes 20 sessions per protocol with a probability of more than 50 percent.

    Measured: Six weeks

Secondary outcomes (1)
  1. Efficacy-Improvement on the MADRS scores compared to baseline.

    Change from baseline in the Montgomery Åsberg Depression Rating Scale (MADRS) scores at week 6 post-randomization compared to baseline.

    The MADRS scores severity of depression on a scale from 0-60. Higher scores indicate worse depression. A total score between 0-6 indicates that the patient is in the normal range (no depression), 7-19 indicates mild depression, 20-34 indicates moderate depression, and a score of 35 and greater indicates severe depression.

    Measured: six weeks
