Quantitative electroencephalographic biomarker of pharmacological treatment response in patients with anxiety disorder: a retrospective study

In clinical practice, qEEG is used as an auxiliary tool in the treatment of anxiety disorders, and is gradually proving its usefulness. In addition to diagnosing anxiety disorders, predicting their reactivity prior to treatment is also important, and qEEG has shown promise in this regard. Patients with anxiety disorders who show elevated T3 and T4 and decreased TBR in beta waves were more likely to respond to drug treatment using antidepressants and benzodiazepines. For patients with anxiety disorders who do not show such characteristics, combination with agents such as antioxidants or other non-pharmaceutical treatment modalities may be preferable.
