ABSTRACT
Methamphetamine is the most commonly used illicit drug in China. We previously demonstrated that 10 Hz rTMS over the DLPFC reduces craving in methamphetamine users. Here, we applied intermittent theta burst stimulation (iTBS), a new form of rTMS, in a large sample at four clinical centers. 126 participants (age 31.64 +/- 6.33; 106 men) with severe methamphetamine use disorder according to DSM-5 were randomized to receive either iTBS or sham over the DLPFC for four weeks (20 daily sessions, 900 pulses per day). Cue-induced craving and cognitive function were assessed before and after rTMS intervention. Relapse was followed up by urine test after discharge from the rehabilitation center. iTBS significantly reduced craving and improved cognition and sleep quality. This study suggests that rTMS may be a useful and safe treatment option for methamphetamine use disorder, warranting future large-scale trials.
