| 摘 要： | 目的:探讨阿尔茨海默病（AD）患者脑灰质容积与整体认知功能水平的关系。方法:收集AD患者20例，MCI患者17例，健康老年对照组（NC）12例，在1.5T MR扫描仪上行T1-3DBRAVO （brain volume）序列检查，利用VBM测出脑灰质容积，行MMSE检查并得出评分，将脑灰质容积与MMSE评分进行多元回归分析，以及运用ROC曲线对所有患者脑灰质容积的诊断效能进行评价分析。结果:所有受试者随着脑灰质容积减少，MMSE评分也减少，脑灰质容积每减少10 mL，MMSE评分下降0.57分（P<0.01），男性患者与低龄组下降的幅度更显著。所有患者脑灰质容积ROC曲线AUC为0.927，最佳阈值为538.49 mL，特异度为90.0%，敏感度为84.6%。结论:所有受试者脑灰质容积下降，整体认知功能水平也下降；所有患者与对照组脑灰质容积可以反映整体认知功能水平，脑灰质容积测量对AD的诊断可提供有价值的信息。

| Abstract: | Objective: To explore the relationship between integral cognitive level and gray matter volume in Alzheimer's disease (AD). Methods: 20 AD patients, 17 MCI patients and 12 healthy old persons were in this study.All subjects were examined by T1-3 D BRAVO (brain volume) sequence in 1.5 T magnetic resonance scanner. The volume of gray matter was measured with Voxel-based morphometry (VBM). All subjects were underwent MMSE and obtained the score of MMSE. The multiple regression analysis of gray matter volume were compared with MMSE score. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of gray matter volume in AD. Results: All of the subjects with reduced gray matter volume of brain, also reduce the MMSE score, gray matter volume decreased by 10 m L and MMSE score decreased by 0.56 points (P<0.01). The decline was more pronounced in men and in younger groups. The area under the curve (AUC) of the gray matter volume was 0.927. The optimum threshold was 538.49 m L, the specificity was 90.0% and the sensitivity was 84.6%. Conclusion: As the volume of gray matter decreased, the level of integral cognition also decreased. The gray matter volume in all patients and control group could reflect the integral cognitive level. The measurement of gray matter volume in the brain could provide valuable information for the diagnosis of AD. |
