RecruitingDrug trialImaging Traumatic Stress and Alcohol Use Disorder With [18F]BavarostatThe overall objective of this study it to use Positron Emission Tomography (PET) brain imaging and a radiotracer that measures the epigenetic marker Histone Deacetylase 6 (HDAC6) to examine HDAC6 expression in people with Post-Traumatic Stress Disorder (PTSD), Alcohol Use Disorder (AUD), or concurrent PTSD and AUD with control groups. While there are a large number of studies conducted in preclinical stress and addiction models, these findings have not been translated to people living with these disorders. This study will examine relationships between HDAC6 and clinical variables of interest. Findings could direct treatment development.
