Journal

Year
2009
Participants
19 trained patients with PTSD and 4 untrained comparison patients (ages 18-65)
Population
Adults
Protocol
QEEG-guided high beta downtraining with 10 Hz uptraining
Sessions
5-7 sessions per trained site

Key findings

  • Excess high-frequency beta (21-30 Hz) was the only significant QEEG abnormality in the group
  • Trained patients' anxiety ratings fell from about 5-7/10 to 0-2/10, and held at 1 month
  • The 4 untrained patients showed little or no change in anxiety over 3 months
  • The author argues QEEG-guided training outperforms non-QEEG-guided alpha-theta approaches reported in the literature

A brief review plus clinic data on QEEG-guided neurofeedback for anxiety in people with post traumatic stress disorder (PTSD). Patients had a QEEG, then trained down excess high-frequency beta (21-30 Hz) and trained up 10 Hz activity at the affected sites, rating their anxiety before, after and one month later. Four patients who declined training served as an informal comparison group. The author reports clinically meaningful drops in anxiety with training and concludes QEEG-guided training appears to help more patients than non-QEEG-guided approaches in the literature.
