摘要
目的:探索抑郁症患者工作记忆损害及其与血清微量元素的关系.方法:采用数字广度、数字2-back、视觉再生及数字-符号转换测试方法,评估30例符合美国精神障碍统计与诊断手册第4版(DSM-IV)诊断标准的抑郁症患者(患者组)和30例健康志愿者(对照组)的工作记忆,同时,检测两组研究对象的血清钙、磷、镁、铜、锌和铁六种微量元素与工作记忆之间的相关性.结果:抑郁症患者数字广度(顺背、倒背、总分)、数字2-back(正确率、反应时)和数字-符号测试成绩显著低于正常对照组(P<0.05),差异有统计学意义;抑郁症组血清中铜含量明显高于对照组,差异具有显著性(P<0.05);数字2-back任务正确率和视觉再生测验得分与镁离子含量呈正相关;数字-符号测验得分与铜离子含量呈正相关;视觉再生测验得分与锌离子含量呈负相关.其他工作记忆测试成绩与离子无相关.结论:抑郁症患者确实存在工作记忆的缺陷,主要体现在工作记忆容量变小,言语工作记忆及中央执行系统功能受损;且抑郁症工作记忆损害可能与血清微量元素锌、铜、镁离子浓度密切相关.
