Summary

Methamphetamine use disorder (MUD) is among the costliest and deadliest substance use disorders (SUDs) world-wide and is frequently comorbid with other mental health conditions. There is no empirically validated medical treatment for MUD. Drug craving is the signature aspect of MUD and other substance use disorders and has been associated with continued drug use and relapse. The investigators and others have shown that transcranial direct current stimulation (tDCS) over dorsolateral prefrontal cortex (DLPFC) can modulate drug craving in different SUDs. tDCS is a method of non-invasive brain stimulation and is a low-cost scalable technology without any serious side effects that delivers low levels of direct current (0.1-2 mAmp) transcranially. However, there are significant inter-individual differences in response to tDCS, which is not well understood but can have profound impact on efficacy. Meanwhile, there are no studies with neuroimaging to show how tDCS affects drug craving. Investigators propose the first combined tDCS/functional Magnetic Resonance Imaging (fMRI) study to examine the acute effects of tDCS on neural substrates underlying drug induced craving.

Conditions

  • Amphetamine Use Disorders

Interventions

DEVICE

Active transcranial Direct Current Stimulation (tDCS)

Transcranial Direct Current Stimulation (tDCS) as a device-based technology is employed by applying a very weak (2 mAmp) direct current over the skull for 1200 seconds with 30 seconds ramp up to 2 mAmp, and 30 seconds ramp down at the end.

DEVICE

Sham transcranial Direct Current Stimulation (tDCS)

Sham Transcranial Direct Current Stimulation (tDCS) as a device-based technology is employed by applying a very weak direct current over the skull. Sham mode will have just 30 seconds ramp up to 2 mAmp, 40 seconds on 2 mAmp stimulation and, 30 seconds ramp down with 1160 seconds no stimulation (just impedance control).
