Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study aims to evaluate the effect of Dorsolateral Prefrontal Cortex (DLPFC) Transcranial Direct Current Stimulation (tDCS) in decreasing distress and cannabis use. 46 participants with Relapse Remitting Multiple Sclerosis (RRMS), Cannabis Use Disorder (CUD) and elevated distress (K10 score of 10-35) will be recruited.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Active tDCS + Mindfulness

Group Type EXPERIMENTAL

Transcranial Direct Current Stimulation (tDCS)

Intervention Type OTHER

tDCS is noninvasive brain stimulation device that modulates brain activity by delivering a low-intensity electrical current (2.0 mA) through sponge electrodes placed on the scalp.

Mindfulness

Intervention Type OTHER

Participants will follow an audio track for guided mindfulness during the stimulation.

Sham tDCS + Mindfulness

Group Type SHAM_COMPARATOR

Sham - Transcranial Direct Current Stimulation (tDCS)

Intervention Type OTHER

The tDCS device is programmed to mimic active tDCS.

Mindfulness

Intervention Type OTHER

Participants will follow an audio track for guided mindfulness during the stimulation.
