In this study, participants with amphetamine use will be recruited from psychiatric clinics. They will be randomly assigned to two different transcranial magnetic stimulation groups, the iTBS and sham groups. Those participants to receive 1-3 sessions in a single day at an interval of 15 minutes, and 5 high-frequency iTBS sessions per week in total four weeks. After the completion of the four-week course, the severity of symptoms for the next one month and three months will be tracked.
The study aims to apply the intermittent theta burst transcranial magnetic stimulation (iTBS) treatment and evaluate the effect in improving craving, affective symptoms, and cognitive function for those participants in the community with amphetamine use. An electroencephalography and blood biomarkers will also be examined to explore the possible mechanisms.
