Anxiety disorders are a common focus of clinical concern and certain forms of anxiety may be conceptualized as disorders of emotional learning. Behavior therapies effective in the treatment of anxiety are modeled on extinction training as a means of reducing pathological anxiety. The present understanding of human anxiety has been informed by preclinical research using rodent models to study the acquisition and extinction of fear. Glutamate appears to have a central role in both of these processes. The authors review this literature and discuss novel applications of D-cycloserine, a partial N-methyl-D-aspartate agonist, for the treatment of anxiety.
焦虑症是临床关注的常见焦点,某些形式的焦虑可被概念化为情绪学习障碍。对治疗焦虑有效的行为疗法是以消退训练为模型,作为减少病理性焦虑的一种手段。目前对人类焦虑的理解得益于临床前研究,该研究使用啮齿动物模型来研究恐惧的习得和消退。谷氨酸似乎在这两个过程中都起着核心作用。作者回顾了这一文献,并讨论了D-环丝氨酸(一种部分N-甲基-D-天冬氨酸激动剂)在治疗焦虑方面的新应用。
