tACS Intervention for Methamphetamine Addiction

A growing body of evidence suggests a wide range of brain areas are critical for regulating cognitive control over decisions and involving in drug related cue processing. Previous studies have demonstrated that transcranial alternating current stimulation (tACS) over prefrontal cortex reduces craving for meth dependences. In this study, the investigators investigated whether a current level of 15mA with a patented frequency of 77.5Hz tACS intervention of prefrontal cortex cortices in methamphetamine addiction could reduce the subjective craving and improve the cognitive abilities.
