Details and patient eligibility

About

OH dependence is associated with DA receptor changes. Both, the apomorphine test and the D2Rec SPECt are usefull for monitoring DA receptor status. We aimed at studying whether DA receptor hypofunction, assessed by means of the apomorphine test and the D2Rec SPECT, is a marker of relapse in detoxified OH dependents patients.
