The Diagnostic Assessment and Intervention Study of Amphetamine Type Stimulus

Study Overview
=================
Brief Summary
-----------------
The purpose of this research is to inspire new medical ideas using brain image technology for the treatment of Amphetamine Type Stimulus addition, at the same time lowing the addition damage.

Detailed Description
-----------------
The study will increase the sample size based on the preliminary work,also, establish drug dependence induced craving associated environmental experiments , by using the multi-lead biofeedback instrument , CogState tester, event-related potentials Recorder and 3.0T high-field magnetic resonance imaging system to record the physiology , electrophysiology and brain changes during craving, taking a subjective self-assessment , clinical observations and physiological responses combined system to evaluate the ATS addiction degree.

Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: general information<br>use cross-sectional study to collect 1000 ATS abuse or dependence patients' general information and 5 ml blood,get their blood plasma and DNA sample in order to explore the possible addict mechanism. | |
| No Intervention: ATS diagnosis and evaluation for abusers<br>Use cohort study design to establish ATS abuse induced craving experiment.Do the initial and follow-up assessment from start smoking to stop smoking after 4 weeks, 12 weeks, 26 weeks, 52 weeks and 26 weeks of returning to the community . Thus compare with normal group to explore the possible psychological abuse mechanism. | |
| Active Comparator: psychological training intervention<br>The main content is self-awareness training, social and moral strengthening, impulse control training , problem solving training , situational awareness training , HIV prevention, social skills training under the family atmosphere , family social skills training , interpersonal skills training, community interaction skills training , psychiatric symptoms of self-monitoring skills training and so on. | Behavioral: psychological rehabilitation training<br>* The main content is self-awareness training, social and moral strengthening, impulse control training , problem solving training , situational awareness training , HIV prevention, social skills training under the family atmosphere , family social skills training , interpersonal skills training, community interaction skills training , psychiatric symptoms of self-monitoring skills training and so on.<br>|
| Active Comparator: brain stimulation intervention<br>Use randomized, prospective pseudo stimulus controlled clinical trial design, evaluation of repetitive transcranial magnetic stimulation of the left frontal lobe dorsal lateral effect on ATS dependent induced cognitive dysfunction and other symptoms. | Radiation: rTMS 10HZ high frequency stimulation<br>* Stimulate the dorsolateral prefrontal and parietal lower part , 4 weeks of therapeutic intervention (5 times / week).<br>|
| No Intervention: ATS diagnosis and evaluation for normal people<br>Do the same initial and follow-up assessment as ATS abusers who stop smoking after 4 weeks, 12 weeks, 26 weeks, 52 weeks and 26 weeks of returning to the community . | |
| Active Comparator: physical and neurological rehabilitation<br>The main content is drug rehabilitation exercise and functional physical training. Rehabilitation led by the discipline cadres , practice once a day, each lasting about 15 minutes . | Behavioral: physical and neurological rehabilitation training<br>* The main content is drug rehabilitation exercise and functional physical training. Rehabilitation led by the discipline cadres , practice once a day, each lasting about 15 minutes .<br>|
| Placebo Comparator: fake brain stimulation intervention<br>fake transcranial magnetic stimulation of the left frontal lobe dorsal lateral effect on ATS dependent induced cognitive dysfunction and other symptoms. | Radiation: fake rTMS 10HZ high frequency stimulation<br>* Fake stimulate the dorsolateral prefrontal and parietal lower part , 4 weeks of therapeutic intervention (5 times / week).<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| the prevalence of ATS abuse or dependence characteristics and pathogenesis | Plasma and DNA samples were collected to carry out the biochemical genetics and immunology research of ATS abuse or dependence , and to explore the prevalence of ATS abuse or dependence characteristics and pathogenesis. | Baseline | 
| the physiological psychology and cognitive impairment characteristic of ATS addicts,trends and ATS conducted cases. | Use repeatable battery for the assessment of neuropsychological status(RBANS),Cog-state cognitive function assessment test,event-related potentials(ERPs),functional magnetic resonance imaging(fMRI) in biology ( molecular genetics, blood biochemistry, electrophysiology , imaging ) , psychology, mental health and other aspects of the system to assess the physiological psychology and cognitive impairment characteristic of ATS addicts , trends and ATS conducted cases. | Baseline |
