This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Summary

This study looks at how opioid use disorder affects thinking skills like memory and attention, and whether these changes can predict how well people do in treatment. Researchers will use brain scans, computer-based cognitive tests, and machine learning to analyze data from 192 adults on stable medication for opioid use disorder. The goal is to better understand why some people struggle with treatment and relapse, which could lead to more personalized care in the future.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this research could lead to better ways to predict who will benefit from treatment and help design more personalized therapies for opioid use disorder.
What could go wrong
This is an observational study, not a treatment trial. It will not directly improve health, and results may not apply to all people with opioid use disorder.
