慢性疼痛与记忆偏差的研究进展

Research Progress of Chronic Pain and Memory Bias

慢性疼痛已经成为全球最普遍的健康问题之一。在我国至少有一亿以上的慢性疼痛患者,慢性疼痛除了会给患者带来生理上长时间的疼痛过敏外,还会导致各种认知障碍,主要表现为对疼痛信息的注意偏差,歧义信息的理解偏差和负面信息的记忆偏差。近年来许多研究探讨了慢性疼痛与注意偏差,歧义信息理解偏差之间的关系,但是缺少对慢性疼痛和记忆偏向之间关系的探讨。基于此,文章将对慢性疼痛的记忆偏差理论模型,生理基础以及影响慢性疼痛患者记忆偏差的多项因素进行综述。

Chronic pain has become one of the most common health problems in the world, and there are at least 100 million chronic pain patients in China. In addition to the physical manifestation of chronic pain patients with long-term pain hypersensitivity, they are often accompanied by cognitive disorders, which are mainly manifested as attention bias to pain information and interpretation of ambiguous information and retention and recall bias of the negative information. In recent years, many studies have explored the relationship between chronic pain and attention bias or interpretation bias, but there is a lack of systematic review on pain-related memory bias. Based on this, this article will review the theoretical model, physiological basis and the factors that affect the memory bias of chronic pain patients.
