- rTMS of left dorsolateral prefrontal cortex (DLPFC) could reduce cue-induced craving for methamphetamine.
- rTMS of left DLPFC could improve cognitive function of methamphetamine users.
- rTMS had no severe negative effects on cognitive function in methamphetamine -addicted patients.
BackgroundRepetitive transcranial magnetic stimulation (rTMS) is a brain stimulation and modulation electrophysiological technique, it can change cortical excitability of target brain region, modulate neuron plasticity and brain connections. Previous researches indicated that rTMS could reduce cue-induced craving in drug addiction.ObjectiveIn this study, we employed real and sham rTMS of the left dorsolateral prefrontal cortex (DLPFC) to test whether it could reduce cue-induced craving for methamphetamine (MA) and influence cognitive function in a randomised clinical trial.MethodsThirty MA-addicted patients were randomized to receive 5 sessions of 8Â min sham or 10Â Hz rTMS to the left DLPFC. Subjects rated their craving at baseline, after exposed to MA-associated cues and after rTMS sessions.ResultsReal rTMS over the left DLPFC reduced craving significantly after 5 sessions of rTMS as compared to sham stimulation. Furthermore, real rTMS improved verbal learning and memory and social cognition in MA-addicted patients.ConclusionsThe present study suggests that 10Â Hz rTMS of the left DLPFC may reduce craving and have no negative effects on cognitive function in MA-addicted patients, supporting the safety of rTMS in treating MA addiction.
