Ninety aged patients at the Philadelphia Geriatric Center were asked to give answers to a 35-item mental status questionnaire which included a new visual counting test. By this mean it was found that 20 of the 90 subjects were not mentally impaired, but 34 had mild dementia, 17 moderate dementia, and 19 servere dementia. These results proved to be well correlated with the clinical findings. The test records showed that as dementia develops, the first thing to be forgotten is the awareness of time, place and recognition (in that order). Then the ability to count disappears. As mental oblivion intervenes, the last thing the patient forgets is his/her own name. It was also noted that patients with mild senile dementia fared better when kept with a similar group than with patients who have moderate or severe dementia.
费城老年医学中心的90名老年患者被要求回答一份包含35个项目的心理状态问卷，其中包括一项新的视觉计数测试。通过这种方式发现，90名受试者中有20人没有精神障碍，但有34人患有轻度痴呆，17人患有中度痴呆，19人患有重度痴呆。这些结果被证明与临床发现密切相关。测试记录显示，随着痴呆症的发展，首先被遗忘的是时间、地点和识别意识（按此顺序）。然后计数能力消失。随着精神遗忘的出现，患者最后忘记的是自己的名字。还注意到，轻度老年痴呆症患者与类似群体在一起时比与中度或重度痴呆症患者在一起时情况更好。
