First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether opioid use disorder and non-fatal overdoses cause a harmful protein called tau to build up in the brain. Researchers used special PET/CT scans on 12 adults, including those with opioid use disorder and healthy volunteers. The goal was to understand long-term brain changes, not to test a treatment.
