Effects of Repetitive Transcranial Magnetic Stimulations in Patients With Amphetamine Use Disorders

"Targeting: The left dorsolateral prefrontal cortex (DLPFC) will be the target for treatment.~Equipment: rTMS will be delivered using a Magstim super rapid magnetic stimulator with a 70-mm air-cooled figure-eight-shaped coil. Resting Motor Threshold (rMT) Measurement: rMT is determined through visual twitch responses in the contralateral hand, identifying the minimal intensity needed to elicit thumb movement in 50% of trials.~rTMS will be administered at a frequency of 15Hz, with each pulse at 100% rMT intensity. Sessions include 60 pulses per train, with a 26-second inter-train pause, across 40 trains, totaling 2400 pulses over a 20-minute session."

The sham group will undergo a placebo procedure using the same rTMS parameters but with a figure-of-eight sham coil, following precedents set by studies on cocaine use disorder treatment (Terraneo et al., 2016).
