Study Description

Brief Summary

This is a single-arm, open-label feasibility study. A maximum of 15 participants will be enrolled. All participants will undergo a novel neurofeedback intervention, targeting down-regulation of deep limbic structures, specifically the amygdalae. Participants will complete 12 neurofeedback sessions delivered twice weekly over 6 consecutive weeks. The intervention will be delivered via the PRISM platform.

Arms and Interventions

Experimental: Patients diagnosed with PTSD

7-15 men and women with PTSD will be recruited from the community and from local clinical programs through a multi-modal outreach program.

Neurofeedback sessions targeting down-regulation of deep limbic structures, specifically the amygdala, delievered via PRISM: a non-significant risk device (software) intended to be used in research studies testing the clinical efficacy of an innovative paradigm for EEG-based neurofeedback. The study will include 12 EEG-NF sessions, administered twice per week for a duration of 6 "active" weeks in total. Twice weekly sessions will be held on non-consecutive days. Each session will last 30 minutes. EFP-EEG-NF training: Each NF training session consists of 5 consecutive sequences of NF presentations. During a "watch" condition (60 seconds) participants are instructed to passively view the animation, and are told that that the scenario does not influence their brain activity. In the "regulate" phase (60 seconds) participants are instructed to lower the room's unrest level. A "rest" phase (15 seconds) follows each sequence, allowing participants to relax.

Outcome Measures

Primary Outcome Measures

  1. Change in CAPS-5 score from screening to completion [Screening visit (Week 0), and Post-Intervention Visit (Week 9)]

    The CAPS-5 is a 30-item structured interview used to: Make current (past month) diagnosis of PTSD Make lifetime diagnosis of PTSD Assess PTSD symptoms over the past week "1, 2" rule is used to determine a diagnosis: a frequency score of 1 (scale 0 = "none of the time" to 4 = "most or all of the time") and an intensity score 2 (scale 0 = "none" to 4 = "extreme") is required for a particular symptom to meet criterion. The assessor combines information about frequency and intensity of an item into a single severity rating. CAPS-5 total symptom severity score is calculated by summing severity scores for the 20 DSM-5 PTSD symptoms.

  2. Change in PCL-5 score from baseline to completion [Baseline visit (Week 1), and Post-Intervention Visit (Week 9)]

    The PCL-5 is a 20-item self-report measure that assesses the 20 DSM-5 symptoms of PTSD. The self-report rating scale is 0-4 for each symptom. A total symptom severity score (range - 0-80) can be obtained by summing the scores for each of the 20 items.
