Abstract

In an attempt to improve the efficacy of psychotherapy for anxiety disorders, preclinical paradigms have recent been translated into novel treatment strategies.[1] Specifically, these studies have examined the role of glutamate, an excitatory neurotransmitter in the mammalian brain, in extinction learning. A receptor complex involved in this process is the N-methyl-D-aspartate (NMDA) receptor. Activation of the NMDA receptor requires binding of both glutamate and the co-agonist glycine. D-cycloserine (D-4-amino-3-isoxazolidone; DCS) is a partial agonist at the glycine recognition site of the glutamatergic NMDA receptor. Animal studies that employed fear-potentiated startle to a conditioned stimulus have demonstrated that this substance can augment extinction learning in rats.[1] The result of this translational work has shown for some studies that DCS can act as a cognitive enhancer to augment exposure strategies during cognitive-behavioral therapy of anxiety disorders.[2] This line of research has gathered a significant amount of attention because it is a prime example of translational research, whereby basic neuroscience directly informs clinical science by identifying a compound and mechanism of treatment change. Following the initial excitement surrounding early DCS augmentation trials, a number of studies have been conducted that provide a more refined picture. These studies further have clarified some of the limitations and indications of DCS as an augmentation strategy.
