Binge alcohol use is not associated with alterations in striatal dopamine receptor binding or dopamine release

Previous imaging studies using Positron Emission Tomography (PET) have shown that alcohol use disorder (AUD) is associated with a decrease in dopamine type 2/3 receptor (D2/3) binding and dopamine transmission. Although binge drinking is a risk factor for future AUD, little is known about the neurobiology of binge drinking in young adults. This study measured D2/3 receptor binding and stimulant-induced dopamine release using PET and...
