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.
目的:探索抑鬱癥患者工作記憶損害及其與血清微量元素的關繫.方法:採用數字廣度、數字2-back、視覺再生及數字-符號轉換測試方法,評估30例符閤美國精神障礙統計與診斷手冊第4版(DSM-IV)診斷標準的抑鬱癥患者(患者組)和30例健康誌願者(對照組)的工作記憶,同時,檢測兩組研究對象的血清鈣、燐、鎂、銅、鋅和鐵六種微量元素與工作記憶之間的相關性.結果:抑鬱癥患者數字廣度(順揹、倒揹、總分)、數字2-back(正確率、反應時)和數字-符號測試成績顯著低于正常對照組(P <0.05),差異有統計學意義;抑鬱癥組血清中銅含量明顯高于對照組,差異具有顯著性(P <0.05);數字2-back 任務正確率和視覺再生測驗得分與鎂離子含量呈正相關;數字-符號測驗得分與銅離子含量呈正相關;視覺再生測驗得分與鋅離子含量呈負相關.其他工作記憶測試成績與離子無相關.結論:抑鬱癥患者確實存在工作記憶的缺陷,主要體現在工作記憶容量變小,言語工作記憶及中央執行繫統功能受損;且抑鬱癥工作記憶損害可能與血清微量元素鋅、銅、鎂離子濃度密切相關.

Aim:To explore the underling mechanism of impairment of working memory in patients with depression from the perspective of biochemistry.Methods:Thirty patients with MDD and 30 healthy controls(HC)were enrolled in this study.Diagnosis was made according to the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition (DSM-IV)criteria.Working memory of the two groups were evaluated by Digital Span Test,Number 2-back Test,Visual Reproduction Test and Symbol Digital Mo-dalities Test.The correlation of working memory and trace elements was also analyzed.Results:Com-pared with the HC group,patients with MDD performaced worse in the Digital Span Test,Number 2-back Test and Symbol Digital Modalities Test.There was no statistical difference in Visual Reproduction Test. The average accuracy of Number 2-back Test had a positive correlation with MG.The score of Visual Re-production Test also had a positive correlation with MG while had a negative correlation with Zn.The score of Symbol Digital Modalities Test was positively related with Cu.There were no statistical correla-tion between other working memory test and trace elements.Conclusion:The working memory of patients with MDD is surely impaired,especially the phonological loop and central executive.In addition,there exsited a close relationship between working memory and Zn,Cu and MG.
