The aim of this study is to assess the efficacy of electroencephalography (EEG) neurofeedback (NF) as an Add-on Treatment for the Anxiety disorder. Meanwhile, evaluate the effect of EEG-NF on cognitive function of Anxiety patients. Furthermore, the investigators will examine the changes in cortisol, gut microbiome and some biomarkers. The hypothesis of this study is that EEG-NF alleviate the anxiety symptoms and improve the cognitive function of Anxiety disorder patients with regulating attention response.


Clinical Trial Description

This is a randomized, double-blind, sham-controlled study using electroencephalography (EEG) neurofeedback (NF) for 2-week treatment. Participants were randomly assigned 1:1 to NF group or sham-control group. The NF group performed six NF sessions every other day in about two weeks. The feedback value of the NF group was about SMR band, while in the control group was pseudo-random numbers. Apart from studying the effects of EEG-NF on severity of anxiety and cognitive function, the secondary outcomes are to examine biomarkers related to inflammatory activity. Scale assessments are performed before the initiation of treatment, week 1, week 2. The Digit Span test, Go/No-Go task Collection of blood, excrement and saliva takes place at two time points, at the baseline, week 2. ;
