Patients with schizophrenia have pronounced deficits in memory for events--episodic memory. These deficits severely affect patients' quality of life and functional outcome, and current medications have only a modest effect, making episodic memory an important domain for translational development of clinical trial paradigms. The current article provides a brief review of the significant progress that cognitive neuroscience has made in understanding basic mechanisms of episodic memory formation and retrieval that were presented and discussed at the first CNTRICS (Cognitive Neuroscience Treatment Research to Improve Cognition in Schizophrenia) meeting in Washington, D.C. During that meeting a collaborative decision was made that measures of item-specific and relational memory were the most promising constructs for immediate translational development. A brief summary of research on episodic memory in schizophrenia is presented to provide a context for investigating item-specific and relational memory processes. Candidate brain regions are also discussed.
精神分裂症患者在事件记忆(情景记忆)方面存在明显缺陷。这些缺陷严重影响患者的生活质量和功能结局,而目前的药物治疗效果甚微,这使得情景记忆成为临床试验范式转化发展的一个重要领域。本文简要回顾了认知神经科学在理解情景记忆形成和提取的基本机制方面取得的重大进展,这些进展在华盛顿特区举行的第一届CNTRICS(改善精神分裂症认知的认知神经科学治疗研究)会议上进行了展示和讨论。在那次会议上,大家共同决定,特定项目记忆和关系记忆的测量是最有希望立即进行转化发展的结构。本文还简要概述了精神分裂症情景记忆的研究,为研究特定项目记忆和关系记忆过程提供背景。同时也讨论了候选脑区。
