A prospective study of patients with moderate (n = 20) and severe (n = 19) dementia of the Alzheimer type was performed to compare the ability of patients to recognize themselves. A Mini-Mental State Examination cut-off score was used to separate those patients with severe dementia (MMSE score < 6) from those with moderate dementia (MMSE = 7--15). Each patient was then scored according to his ability to name two body parts correctly and to recognize himself in a mirror. Severe degrees of dementia were significantly associated with the inability of patients to recognize themselves while those with moderate degrees of dementia still retained this capacity.
对20例中度和19例重度阿尔茨海默病型痴呆患者进行了一项前瞻性研究，以比较患者的自我识别能力。采用简易精神状态检查表临界值分数，将重度痴呆患者（简易精神状态检查表分数<6）与中度痴呆患者（简易精神状态检查表分数=7-15）区分开来。然后根据每位患者正确说出两个身体部位的能力以及在镜子中认出自己的能力进行评分。重度痴呆程度与患者无法自我识别显著相关，而中度痴呆患者仍保留这种能力。
