Overview
Brief Summary
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.
Detailed 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.

Intervention: SSRI or SNRI or benzodiazepines or tricyclic antidepressants or other antidepressants or antipsychotics or other sedative-hypnotics
Experimental:
NF group participants receive 24 min NF sessions over the Motor sensory Cortex, 2-3 days per week, for 2 weeks combine a selective serotonin reuptake inhibitor (SSRI) or a serotonin or norepinephrine reuptake inhibitors (SNRI) or benzodiazepines or tricyclic antidepressants or other antidepressants or antipsychotics or other sedative-hypnotics
Intervention: Neurofeedback system
Healthy Experimental:

Outcomes
Primary Outcomes
The change of scores in Hamilton Anxiety Rating Scale (HAMD) from baseline to week 2.
Time Frame: baseline, Week 1, week 2
The main objective is to explore whether NF add on medicine will improve the anxiety symptoms after 2 weeks of treatment, and investigators assess the scale at baseline and week 1, 2. Hamilton Anxiety Rating Scale (HAMD) items was used to evaluate the severity of symptoms of anxiety. A total score of more than 29 may indicate severe anxiety symptoms; A score above 14 may be mild to moderate anxiety; If the score is less than 7, the patient has no symptoms of anxiety. The higher the total score of the scale, the more severe the anxiety symptoms.
The change of scores in GAD-7 from baseline to week 2.
Time Frame: baseline, Week 1, week 2
The main objective is to explore whether NF add on medicine will improve the anxiety symptoms after 2 weeks of treatment, and investigators assess the scale at baseline and week 1, 2. GAD-7 items were used to evaluate the severity of symptoms of anxiety. A total score of more than 15 may indicate severe anxiety symptoms; A score above 5 may be mild to moderate anxiety; If the score is less than 4, the patient has no symptoms of anxiety. The higher the total score of the scale, the more severe the anxiety symptoms.
