Официальное название

Telehealth-Delivered tDCS for Cannabis Addiction Recovery: The C.A.R.E.S. (Cannabis Addiction Recovery Enhancement Stimulation) Initiative

Обзор

The purpose of this sham-controlled pilot randomized controlled trial (RCT) is to evaluate the feasibility, safety, and preliminary efficacy of a one-month intervention consisting of 20 home-based active or sham RS-tDCS sessions paired with audio track guided mindfulness meditation practice in otherwise healthy adults seeking to reduce cannabis use in the context of cannabis use disorder (CUD).

Вмешательства

• Устройство Active Transcranial Direct Current Stimulation (tDCS)
  tDCS is a noninvasive brain stimulation device that modulates brain activity by delivering low-intensity electrical current (2.0 mA) through scalp sponge electrodes. Device is programmed to ramp up to 2.0 mA (for 30 seconds), provide constant current throughout the session (19 minutes), and then ramp down (for 30 seconds) at the end.
• Устройство Sham Transcranial Direct Current Stimulation (tDCS)
  tDCS is a noninvasive brain stimulation device that modulates brain activity by delivering low-intensity electrical current (2.0 mA) through scalp sponge electrodes. Device is programmed to ramp up to 2.0 mA (for 30 seconds) followed by a ramp down (30 seconds), with no current delivery for 18 minutes, and then ramp up (for 30 seconds) and down (for 30 seconds) at the end.
• Поведенческое Mindfulness meditation
  Participants will follow an audio track for guided mindfulness during the stimulation.
