Brief Summary

In 2021, nearly 296 million people worldwide used psychoactive substances, highlighting a significant need for effective interventions for disorders such as Methamphetamine Use Disorder (MUD). Despite existing treatments, including behavioral therapies and medications, the relapse rates remain high, signaling the need for more potent and targeted approaches. This clinical trial investigates high-intensity transcranial alternating current stimulation (Hi-tACS), a non-invasive method that applies 15mA electrical currents with a patented frequency of 77.5Hz to modulate brain activity. Hi-tACS has shown promise in preliminary studies for its ability to reduce drug cravings significantly by influencing brain regions crucial in addiction. The primary aim of this study is to evaluate the effectiveness of Hi-tACS in curbing cravings in individuals with MUD. As secondary objectives, the trial will also explore the potential benefits of Hi-tACS in alleviating other clinical symptoms, enhancing cognitive performance, and positively influencing brain activity. This study seeks to establish Hi-tACS as a more effective treatment option that could lead to substantially lower relapse rates for individuals with MUD.

Outcome Measures

Primary Outcomes (2)

  • Subjective craving

    Subjective craving is measured by using Analogue Scale (VAS) for craving after watching video stimulus, ranging from 0 to 100, where 0 indicates no craving at all and 100 represents an extremely intense craving.

    The day before intervention, the day after intervention, 2 weeks after intervention and 3 months after intervention.

  • Objective craving

    Objective craving is measured by using the EEG recording to reflect the brain activity of individuals to the drug-related videos and pictures. EEG data were recorded when participants watch videos in Video-induced Craving Task (VCT) and when participants see pictures in Picture-induced Craving Task (PCT). The amplitude of late positive potential (LPP) was considered as a major outcome of the drug-cue related ERP, higher LPP is related to higher craving.

    The day before intervention, the day after intervention, 2 weeks after intervention and 3 months after intervention.

Secondary Outcomes (6)

  • Resting-state brain activity

    The day before intervention, the day after intervention, 2 weeks after intervention and 3 months after intervention.

  • Depression status

    The day before intervention, the day after intervention, 2 weeks after intervention and 3 months after intervention.

  • Anxiety status

    The day before intervention, the day after intervention, 2 weeks after intervention and 3 months after intervention.

  • Sleep status

    The day before intervention, the day after intervention, 2 weeks after intervention and 3 months after intervention.

  • Impulsivity

    The day before intervention, the day after intervention, 2 weeks after intervention and 3 months after intervention.

  • +1 more secondary outcomes

Other Outcomes (1)

  • side effect measurements

Study Arms (2)

Active tACS group

ACTIVE COMPARATOR

In the active group, the intervention is carried out using Hi-tACS with an intensive current of 15mA and a frequency of 77.5 Hz. Each intervention session lasts for 40 minutes, with two sessions conducted daily - one in the morning and one in the afternoon. The intervention is spread over a 10-day period, with sessions taking place five days per week, totaling two weeks.

Device: Active transcranial alternating current stimulation

Sham tACS group

SHAM COMPARATOR

The sham group undergoes sessions with the same technical settings, designed to produce similar scalp sensations but without effective penetration of the electric field into the brain. Each session lasts for 40 minutes, with two sessions conducted daily - one in the morning and one in the afternoon. The intervention is spread over a 10-day period, with sessions taking place five days per week, totaling two weeks.

Device: Sham transcranial alternating current stimulation

Interventions

Hi-tACS with a current level of 15mA with a patented frequency of 77.5Hz.

Active tACS group

The device for the sham group has the same appearance and technical settings as the one used in the active group, designed to produce similar sensations on the scalp, but without effective penetration of the electric field into the brain.
