Examining brain activity patterns related to opioid relapse during treatment

Functional Connectivity Mechanisms of Opioid Abstinence

Observational Yale University · NCT06651333

This study is testing how brain activity patterns might predict the risk of relapse to opioid use in people who have just started treatment with methadone or buprenorphine.

What this trial studies

This observational study investigates the functional connectivity patterns in the brain using fMRI to understand the risk of relapse to illicit opioids among individuals undergoing treatment for opioid use disorder. Participants will be those who have recently started treatment with methadone or buprenorphine at the APT Foundation. The study aims to identify brain activity that correlates with relapse risk during this critical period of treatment. By analyzing these patterns, researchers hope to gain insights that could inform future interventions and support strategies for individuals in recovery.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals who have recently initiated treatment for opioid use disorder with methadone or buprenorphine and are eligible for MRI scanning.

Not a fit: Patients with acute psychosis, severe cognitive impairment, or other significant medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved strategies for preventing relapse in individuals undergoing treatment for opioid dependence.

How similar studies have performed: Other studies have explored brain activity in relation to substance use disorders, suggesting that this approach has potential but may still be considered novel in the specific context of opioid relapse.

Eligibility criteria

Exclusion Criteria:

* current acute psychosis, mania, or suicidal ideation with intent, as assessed during screening with the SCID-5;
