Key result
Five sessions of pIR HEG neurofeedback linked to ~31% lower depression scores and reduced anxiety.
Why the study?
This is the first formally documented investigation of passive infrared hemoencephalography neurofeedback applied to a mental health population with mixed diagnoses.
Does passive infrared hemoencephalography (pIR HEG) neurofeedback improve symptoms of anxiety, depression, and self-efficacy in clients with mixed mental health diagnoses?
Observational (n=66)
No
Does passive infrared hemoencephalography (pIR HEG) neurofeedback improve symptoms of anxiety, depression, and self-efficacy in clients with mixed mental health diagnoses?
pIR HEG neurofeedback may significantly improve symptoms of anxiety, depression, and self-efficacy in patients with mixed mental health diagnoses.

May reduce anxiety and depression in uncontrolled mental health cases; leaves open specific efficacy versus sham in randomized trials.
Clients with mixed diagnoses were provided passive infrared hemoencephalography (pIR HEG) neurofeedback in a mental health private practice treatment setting. This is the first formally documented investigation of pIR HEG neurofeedback applied to a mental health population. Both qualitative and quantitative data were collected. Results from 66 clients showed that five sessions of neurofeedback resulted in statistically significant changes in anxiety, depression, limbic overload, and coping self-efficacy. For clients who completed 10 or 15 sessions, results showed robust changes in anxiety, depression, limbic overload, general self-efficacy, coping self-efficacy, and dissociation. The impact of neurofeedback on self-efficacy is discussed as well as limitations and implications for future research.

Christine Tyrrell Baker (2023) conducted an observational in Mixed mental health diagnoses (anxiety, depression, PTSD) (n=66). Noninvasive prefrontal pIR HEG neurofeedback vs. Baseline (within-subjects) was evaluated on Depression severity (PHQ-9 score) after 5 sessions (Hedges' g 0.60, p=<0.001). Five sessions of noninvasive prefrontal pIR HEG neurofeedback significantly reduced depression scores (PHQ-9 from 12.09 to 8.30, p<0.001) and anxiety scores in clients with mixed mental health diagnoses.
