快感缺乏,指体验愉快能力的降低,它在精神分裂症病因学中发挥着很重要的作用,其存在增加了罹患精神分裂症谱系疾病的风险。然而,精神分裂症中做情绪体验的快感缺乏研究由于方法学的问题常不能得到一致的结果。从奖励系统入手,最新的研究证据支持精神分裂症期待性愉快损伤,而消费性愉快相对完好。在分裂型人格中似乎也存在类似的损伤模式。该文从精神分裂症谱系的角度,探讨了从奖励系统考察快感缺乏的可能。

Anhedonia is defined as the diminished capacity to experience pleasure,and it plays a very important role in the aetiology of schizophrenia.However,previous studies focusing on positive emotional experience in schizophrenia often have inconsistent findings.New perspective on reward system indicates that schizophrenia impairs in anticipatory pleasure rather than consummatory pleasure.This kind of deficit may occur in individuals along the spectrum disorders such as schizotypal personality disorders.This review highlights the relationship between reward systems and anhedonia in individuals with schizophrenia spectrum disorders.
