多巴胺(DA)系统在大脑奖赏机制和药物滥用发展中的作用已经得到很好的证实。我们回顾了早期的动物和人类研究DA和酒精中毒的一些相关问题,这些研究。目前的动物和人类数据表明,在酒精中毒的情况下,DA系统的几个变化。受体研究表明,DA D2受体密度和功能至少在1型酗酒者中较低,这表明他们可以从增强DA能活性的药物中获益,如部分DA受体激动剂。这些药物可以通过减少戒酒时对酒精的渴望和酒精在延髓核(NAC)中释放DA后的欣快感来帮助恢复DA能活性的次优水平,从而为复发提供负强化。
The role of the dopamine (DA) system in brain reward mechanisms and the development of substance abuse has been well established. We review earlier animal and human studies on DA and alcoholism with some relevant issues relating to those studies. The present animal and human data suggest several alterations in the DA system in the context of alcoholism. Receptor studies imply that DA D2receptor density and function are lower at least among type 1 alcoholics, which suggests that they could benefit from drugs that enhance DAergic activity, such as partial DA agonists. These drugs could help to restore suboptimal levels of DAergic activity by reducing both the craving for alcohol in abstinence and the euphoria subsequent to alcohol's release of DA in the nucleus accumbens (NAC), thus providing negative reinforcement for relapse.
