. To investigate the diagnostic accuracy of the overlapping infinity loops, wire cube, and clock drawing tests (CDT) in the detection of mild cognitive impairment (MCI) and dementia. . The participants were 60 normal controls (NC), 35 patients with MCI, and 47 patients with mild dementia. . The results illustrate that infinity loops, cube, or CDT were not able to discriminate between NC and MCI groups. In dementia detection, the CDT had the highest diagnostic accuracy (sensitivity 76.6% and specificity 87.4%) followed by infinity loops (sensitivity 63.8% and specificity 91.6%) and cube (sensitivity 93.6% and specificity 46.3%). . This study demonstrates that the three drawing tests are sensitive detectors of dementia but not MCI.
. 为研究重叠无限循环、金属丝立方体和画钟试验（CDT）在检测轻度认知障碍（MCI）和痴呆症方面的诊断准确性。. 参与者包括60名正常对照（NC）、35名MCI患者和47名轻度痴呆患者。. 结果表明，无限循环、立方体或CDT无法区分NC组和MCI组。在痴呆症检测中，CDT的诊断准确性最高（敏感性76.6%，特异性87.4%），其次是无限循环（敏感性63.8%，特异性91.6%）和立方体（敏感性93.6%，特异性46.3%）。. 本研究表明，这三种绘图测试是痴呆症的敏感检测方法，但不是MCI的检测方法。
