Investigating the Mu:Kappa Opioid Receptor Imbalance in Alcohol Use Disorder
Yale University
Summary
The primary objective of this multimodal positron emission tomography (PET) study is to use PET brain imaging to measure both MOR (Mu-Opioid receptors) and KOR (kappa-opioid receptors) in participants with alcohol use disorder (AUD) and to quantify the relationships between MOR and KOR, separately and jointly, to key clinical outcomes (e.g., craving, mood, withdrawal, time to lapse) during a quit attempt.
Description
Primary Objective The primary objective of this multimodal positron emission tomography (PET) study is to use PET brain imaging to measure both MOR (Mu-Opioid receptors) and KOR (kappa-opioid receptors) in participants with alcohol use disorder (AUD) and to quantify the relationships between MOR and KOR, separately and jointly, to key clinical outcomes (e.g., craving, mood, withdrawal, time to lapse) during a quit attempt. Investigators will achieve this goal by completing the following aims: Aim 1: To determine whether participants with AUD in early abstinence (up to 6 days) have altered MO…
