Self Neuro-modulation Therapy for Major Depressive Disorder (MDD) With Anhedonia

Sponsored by GrayMatters Health Ltd.

About this study

The purpose of this research is to learn more about a new treatment for individuals with Major Depressive Disorder (MDD) with heightened symptoms of anhedonia (i.e. loss of pleasure or interest in activities). The treatment is called Prism, and it is a software device intended for a novel form of neurofeedback training to be used in a clinic setting. During this study, the subject will use different techniques to measure brain activities, including magnetic resonance imaging (MRI) and electroencephalography (EEG).

The study is comprised of the Screening Visit, Baseline Assessment, Pre-training Visit, 20 NF Training Visits (two training visits per week over 10 weeks), two Booster NF Training Visits (Week 16, and Week 20, and the 3-Month Follow-up Assessment Visit (Week 24). Participants will receive 20 NF sessions. The study will test the following hypothesis: * H0: M(Anhedonic)RS-EFP = M(Anhedonic)Sham-EFP * H1: M(Anhedonic)RS-EFP ≠ M(Anhedonic)Sham-EFP Where: M(Anhedonic)RS-EFP and M(Anhedonic)Sham-EFP are the mean changes from baseline HDRS-17 score in the Active and Sham arms of the Anhedonic MDD participants. \*HDRS-21 is administered for cluster analysis

Only the research team can confirm whether you qualify. The intake questionnaire is the best way to find out.

Completing a questionnaire on Clinably does not enroll you in a clinical trial or confirm your eligibility. Only the research team can determine whether you qualify to participate. These results are based on the information you provide and are intended to help you start a conversation with the research team.
