About this trial

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).

  • Prism Training

    Device

    Participants will complete 20 Prism training sessions. The Prism training sessions take place twice a week over a 10-week period, with a minimum of one night of sleep between sessions. Participants will also receive two single booster sessions, 4 weeks and 8 weeks after their last NF session completed.

Trial outcomes

Primary outcomes

1

HDRS-21

Hamilton Rating Scale for Depression - the maximum score is 64. A score above 20 is considered a severe depression.

Time frame
Change from baseline to week 12 (post training visit)

Secondary outcomes

1

SHAPS-C

Snaith-Hamilton-Pleasure scale - is a 14- item self-administered measure of anhedonia symptoms.

Time frame
Change from baseline to week 12 (post-training visit)
2

HDRS-21

Hamilton Rating Scale for Depression - the maximum score is 64. A score above 20 is considered a severe depression.

Time frame
Change from baseline to 3-month FU visit
3

CGI-I

Clinical global impression - The 7-point CGI-I scale rates improve with a (1) representing a very much improved' patient and (7) representing a patient who has become 'very much worse' due to treatment. The rating (4) represents a patient displaying no change from the treatment.

Time frame
