Brain Mechanisms of Reducing Polysubstance Use

Not Applicable

Recruiting

• Conditions: Multiple Drug Use

• Registration Number: NCT06324786
• Lead Sponsor: Arizona State University

Brief Summary

The proposed study will test whether neurofeedback (NF) could optimize integrative body-mind training (IBMT) practice.

Detailed Description

The proposed study will test whether real-time NF could optimize IBMT practice and improve effects in reducing polysubstance use through targeting self-control networks in the brain.

Primary Outcome Measures

Name	Time	Method
Intervention effects on brain grey matter using fMRI	The outcome measures are assessed in-person at baseline, 2-4 weeks and 3 months	Brain volume changes such as anterior and posterior cingulate cortex measured by fMRI structural imaging
Intervention effects on brain white matter using fMRI	The outcome measures are assessed in-person at baseline, 2-4 weeks and 3 months	Brain white matter changes such as anterior and posterior cingulate cortex measured by fMRI diffusion tensor imaging
Intervention effects on brain function using Functional Magnetic Resonance Imaging (fMRI)	The outcome measures are assessed in-person at baseline, 2-4 weeks and 3 months	Brain connectivity changes such as anterior and posterior cingulate cortex measured by fMRI resting state imaging

Secondary Outcome Measures

Name	Time	Method
Intervention effects on addiction behavior using substance use questionnaires in PhenX Toolkit	The outcome measures are assessed in-person at baseline, 2-4 weeks and 3 months	Intervention leads to a significant reduction in craving and substance use measured by substance use questionnaires in PhenX Toolkit
