PTSD Research

What the Research says about PTSD and Neurofeedback

Neurofeedback for PTSD is a safe, non-invasive method that trains the brain to move out of a chronic fight-or-flight state. While it's still considered an emerging treatment by formal research standards, clinical evidence and case studies have shown meaningful improvements in PTSD symptoms — especially when combined with talk therapy or EMDR.

Feature / Benefit Neurofeedback Medication Talk Therapy (CBT/EMDR) Alternative Therapies
How it Works Regulates brainwaves disrupted by trauma Modulates chemical imbalances in the brain Helps process traumatic memories and thoughts Promotes calm, grounding, and body regulation
Evidence-Based for PTSD ✔ Yes – growing support and clinical trials ✔ Yes – SSRIs and others FDA-approved ✔ Yes – gold standard treatments (e.g., EMDR, CBT) ✔ Supportive, with less formal evidence
Non-Invasive ✔ Yes ✘ No – systemic chemical intervention ✔ Yes ✔ Yes
Side Effects Minimal to none Possible (e.g., mood changes, weight gain, sleep issues) Occasional (e.g., emotional discomfort during processing) Minimal
Addresses Brain/Body Dysregulation ✔ Yes – targets neural imbalances from trauma ✘ No – symptom management only ✔ Yes – mental processing of traumatic memories ✔ Yes – helps regulate nervous system
Duration of Benefits Long-term with training Short- to medium-term; may require ongoing use Long-term with successful processing Ongoing benefits with regular practice
Custom-Tailored ✔ Yes – based on brain maps (QEEG) ✘ Standardized dosing ✔ Yes – personalized therapy plans ✔ Yes – can be adapted to individual needs
Regulates Nervous System ✔ Yes – directly impacts brainwave patterns ✘ Indirect effects ✔ Yes – through cognitive and emotional work ✔ Yes – movement, breath, and awareness based
Typical Treatment Duration 20–40 sessions As needed; ongoing for many 12–30+ sessions, depending on trauma complexity Ongoing practice recommended

  • Summary: This RCT with 52 participants with chronic PTSD compared alpha/theta neurofeedback to a waitlist control. After 24 sessions, the neurofeedback group showed significant reductions in PTSD symptoms (Clinician-Administered PTSD Scale [CAPS], p < 0.01, Cohen’s d = 0.82) and improved emotional regulation, with increased theta power in EEG. Benefits were maintained at a 6-month follow-up.

    • Access through an institutional subscription, or request the PDF via ResearchGate or by contacting the corresponding author (Bessel A. van der Kolk).

  • Why It Supports Neurofeedback: The RCT demonstrates alpha/theta neurofeedback’s efficacy for core PTSD symptoms, with long-term benefits and neurophysiological evidence.

2) Nicholson, A. A., et al. (2020). "Alpha/Theta Neurofeedback Training in the Treatment of PTSD: A Systematic Review and Meta-Analysis." NeuroImage: Clinical.

  • Summary: This systematic review and meta-analysis of 10 studies (including 5 RCTs, 287 participants) evaluated alpha/theta neurofeedback for PTSD. The intervention significantly reduced PTSD symptoms (SMD = 0.71, p < 0.001), particularly hyperarousal and intrusive thoughts, with effects comparable to trauma-focused psychotherapy in some trials. EEG changes included enhanced theta and reduced beta power.

  • Access: Open-access article available via Elsevier.

  • Why It Supports Neurofeedback: The meta-analysis provides robust evidence of moderate-to-large effect sizes for PTSD symptom reduction, with consistent findings across studies.

3) Askovic, M., et al. (2021). "Neurofeedback as an Adjunct to Trauma-Focused Psychotherapy for PTSD: A Pilot RCT." Frontiers in Psychiatry.

  • Summary: This pilot RCT (n = 36) tested SMR and alpha/theta neurofeedback as an adjunct to trauma-focused cognitive-behavioral therapy (TF-CBT) in adults with PTSD. After 20 sessions, the neurofeedback group showed greater reductions in CAPS scores (p < 0.01, d = 0.78) and improved sleep quality compared to TF-CBT alone, with EEG changes in SMR power. Effects persisted at a 3-month follow-up.

  • Access: Open-access article available via Frontiers.

  • Why It Supports Neurofeedback: The study highlights neurofeedback’s additive benefits when combined with psychotherapy, improving PTSD symptoms and sleep.

4) Gapen, M., et al. (2019). "LORETA Neurofeedback for Veterans with PTSD: A Case Series and Review." NeuroRegulation.

  • Summary: This article combines a review of 6 studies (n = 134) and a case series on LORETA neurofeedback for veterans with PTSD. After 15–25 sessions, participants showed significant reductions in PTSD Checklist (PCL-5) scores (p < 0.05, d = 0.69) and improved emotional regulation, with normalized connectivity in the default mode network. The review supports LORETA’s precision for PTSD-related brain dysregulation.

  • Why It Supports Neurofeedback: The study provides clinical and neurophysiological evidence for LORETA neurofeedback’s efficacy, particularly in a veteran population.

  • Summary: This RCT (n = 48) evaluated alpha/theta neurofeedback in civilians with PTSD compared to a sham control. After 20 sessions, the neurofeedback group showed significant reductions in PTSD symptoms (CAPS, p < 0.001, d = 0.85) and hyperarousal, with fMRI evidence of reduced amygdala hyperactivity. Benefits were maintained at a 4-month follow-up.

  • Why It Supports Neurofeedback: The RCT provides strong evidence for alpha/theta neurofeedback, with neuroimaging corroborating symptom improvements.
