Intervention / TreatmentIntervention / Treatment |
|---|---|
|
Experimental: rTMS treatment group
For rTMS treatment, we will stimulate the dorsal lateral prefrontal cortex of each patients using the iTBS pattern everyday.
Treatment will lasted for 4 weeks.
|
The iTBS group received 900 pulses per day: 3-pulse 50-Hz bursts given every 200 ms (at 5 Hz), 2 s on and 8 s off for 5 min, at 100% resting motor threshold (rMT), over the left DLPFC (F3, EEG system) (4 weeks, 20 daily sessions).
A figure-8-shaped Cool-B70 stimulation coil from MagPro X100 device (MagVenture, Farum, Denmark) was used for accurately targeted stimulation.
Motor threshold was determined over the left motor cortex, by finding the lowest intensity that produced a motor response in the right abductor pollicis brevis muscles (APB), which produced five motor-evoked potentials responses of at least 50 uV in 10 trials.

Sham Comparator: sham rTMS treatment group
For sham rTMS treatment, we will stimulate the dorsal lateral prefrontal cortex of each patients using the sham iTBS pattern and sham coil everyday.
Treatment will lasted for 4 weeks.
|
The sham iTBS group received sham stimulation over the left DLPFC (F3, EEG system) (4 weeks, 20 daily sessions).
A figure-8-shaped sham Cool-B70 stimulation coil from MagPro X100 device (MagVenture, Farum, Denmark) was used for accurately targeted stimulation.
Motor threshold was determined over the left motor cortex, by finding the lowest intensity that produced a motor response in the right abductor pollicis brevis muscles (APB), which produced five motor-evoked potentials responses of at least 50 uV in 10 trials.

Self-report drug use and urine test
Time Frame: 16 weeks
|
Patients will be asked to report their drug use for 16 weeks every day and do urine tests once a week for 16 weeks.
Loss of visit or rejecting to report or rejecting to do urine tests will be treated as drug use positive (relapse).

Time Frame |

Cognitive function assessed by RBANS
Time Frame: 4 weeks
|
Cognitive function was assessed using the Chinese version of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS).
The RBANS was administered at baseline and after the 4-week intervention.
The battery includes 12 subtests that generate index scores for immediate memory, visuospatial/constructional function, language, attention, and delayed memory, as well as a Total Scale Score.
Higher scores indicate better cognitive performance.
The RBANS Total Scale Score was defined as the summary cognitive outcome, and the five index scores were used to characterize domain-specific cognitive changes.

Magnetic resonance imaging
Time Frame: 4 weeks
|
Magnetic resonance imaging is collected once before and once after intervention, mainly collecting structural images, resting state MRI.
|
4 weeks

Safety measurements
Time Frame: 12 weeks
|
The safety indicators included the occurrence of adverse events and serious adverse events.
