Intervention / Treatment |
---|---|
EXPERIMENTAL: 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

EEG-neurofeedback is an operant conditioning procedure in which people learn to improve the brain's functional activity and used as a way to effect long-term change in abnormal brain activity thus alter corresponding cognitive function.
In addition, its potential to be used to elucidate the mechanisms underlying psychopathology by evaluating the subjective effect of the modulation of specific brain areas has become apparent.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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.
|
baseline, Week 1, week 2
|
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.
|
baseline, Week 1, week 2

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The change of scores in the State-Trait Anxiety Inventory (STAI) 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. State-Trait Anxiety Inventory (STAI) items was used to evaluate the severity of symptoms of anxiety.
The total score of STAI ranged from 20 to 80.
The higher the score, the worse the severity of symptoms of anxiety.
|
baseline, Week 1, week 2
|
The change of scores in Pittsburgh Sleep Quality Index (PSQI) from baseline to week 2.
Time Frame: baseline, Week 1, week2
|
The aim is to investigate whether NF training in addition to regular treatment with medicine will improve the sleep quality as measured with Pittsburgh Sleep Quality Index (PSQI) after 2 weeks of treatment compared to sham-group, and investigators assess the scale at baseline, week1and week 2. PSQI was used to evaluate the sleep quality of the subjects in the latest month.
The total score of PSQI ranged from 0 to 21.
The higher the score, the worse the sleep quality.
|
baseline, Week 1, week2
|
The change of scores in Insomnia Severity Index (ISI) from baseline to week 2.
Time Frame: baseline, Week 1, week 2
|
The aim is to investigate whether NF training in addition to regular treatment with medicine will improve the sleep quality as measured with Insomnia Severity Index (ISI) after 2 weeks of treatment compared to sham-group, and investigators assess the scale at baseline, week1and week 2. The ISI scale was used to evaluate the severity of insomnia.
The higher the score, the more severe the insomnia
|
baseline, Week 1, week 2
|
The change of scores in Mindful Attention Awareness Scale, MAAS) from baseline to week 2.
Time Frame: baseline, Week 1, week 2
|
The aim is to investigate whether NF training in addition to regular treatment with medicine will improve the level of mental resilience, attention and consciousness as measured with Mindful Attention Awareness Scale, MAAS) after 2 weeks of treatment compared to sham-group, and investigators assess the scale at baseline, week1and week 2. The MAAS scale evaluates assess the level of mental resilience.
The higher the score, the higher the participant's level of mindfulness.

|
The changes of levels of biomarkers in peripheral blood from baseline to week 2
Time Frame: baseline, week 2
|
The aim is to investigate the change of cortisol level of saliva and intestinal flora as active stimuli in addition to regular treatment with medicine after 2 weeks of treatment compared to sham group, and investigators collect the specimens at baseline and week 2. Saliva collection tube to collect saliva, collect naturally discharged saliva in a clean test tube (at least 2ml). Saliva was centrifuged under 1500rpm for 15 minutes and the filtrate was cryopreserved at-80 C. the saliva was analyzed by ELISA kit. Fecal collection: a) intercept the middle part of the sample with a sterile toothpick or fecal sampler (the surface of feces contains exfoliated cells of intestinal mucosa; the outside is easy to be contaminated, and some bacterial DNA begins to degrade after contact with air), take about the size of peanuts and put them into aseptic 2.0mL centrifuge tubes, 3-5 tubes for each sample are taken for backup#and then put into-80°C cryopreservation after sub-packaging. |

|
The change of reaction time in Go/No-Go task from baseline to week 2.
Time Frame: baseline, week 2
|
The aim is to investigate whether NF training in addition to regular treatment with medicine will improve attention as measured with Go/No-Go task after 2 weeks of treatment compared to sham-group, and investigators assess the scale at baseline and week 2. The Go/No-Go task scale evaluates assess the level of attention.
The shorter the reaction time, the higher the level of attention.
|
baseline, week 2
|
The accuracy in the Digit Span test (DSP) from baseline to week 2.
Time Frame: baseline, week 2
|
The aim is to investigate whether NF training in addition to regular treatment with medicine will improve short-term memory and working memory as measured with the Digit Span test (DSP) after 2 weeks of treatment compared to sham-group, and investigators assess the scale at baseline and week 2. The Digit Span test (DSP) scale evaluates assess short-term memory and working memory.
The higher the accuracy, the better the level of memory.
|
baseline, week 2
|
The change of scores in Self-Rating Anxiety Scale (SAS) from baseline to week 2.
Time Frame: baseline, week 2
|
The main objective is to explore whether NF will improve the anxiety symptoms after 2 weeks of treatment, and investigators assess the scale at baseline and week 2. Self-Rating Anxiety Scale (SAS)items was used to evaluate the severity of symptoms of anxiety.
A total score of more than 56 may indicate severe anxiety symptoms; A score above 40 may be mild to moderate anxiety; If the score is less than 20, the patient has no symptoms of anxiety.
