Neurofeedback

Neurofeedback uses real-time EEG sensors placed on the scalp to give patients direct feedback on their own brainwave activity. The protocol pairs target brainwave patterns with reward signals (audio tones, video imagery), allowing the patient to learn to shift their own neural state through operant conditioning.

For trauma applications, the typical target is reducing high-beta brainwave activity (associated with hypervigilance and threat-monitoring) and increasing alpha activity (associated with calm relaxed alertness). The 2018 RCT by van der Kolk and colleagues applied neurofeedback to chronic PTSD patients with limited response to other treatments and reported effect sizes comparable to other established trauma treatments.

Course length: 30 to 40 sessions is typical. Each session runs 30 to 60 minutes. Protocols vary by clinical target. The cost can be substantial, sometimes $4,000 to $8,000 for a full course, though insurance coverage is improving.

Best fit: treatment-resistant PTSD where EMDR or somatic experiencing have stalled; ADHD (long evidence base); chronic anxiety with strong autonomic-arousal component; patients who prefer technology-assisted modalities.

Limitations: cost, time commitment (30+ sessions), and requirement for trained clinical practitioner. The home-use neurofeedback devices have weaker evidence than clinical protocols.

Training credentials in the US: BCIA (Biofeedback Certification International Alliance) is the primary credentialing body. Look for BCN-certified practitioners.
