The Extended Scale for Dementia was introduced as a test for grading the intellectual function of patients with dementia. Its use in discriminating demented patients from nondemented control subjects has been explored. The test had a sensitivity of 93% and a specificity of 96% in patients over the age of 65 years, but the sensitivity fell to 75% in those younger than 65 years. The scale may be useful, particularly for patients over the age of 65 years, in helping to distinguish dementia from normality.
痴呆扩展量表被用作评估痴呆患者智力功能的一项测试。人们已经探讨了其在区分痴呆患者与非痴呆对照受试者方面的用途。该测试在65岁以上患者中的灵敏度为93%，特异度为96%，但在65岁以下患者中灵敏度降至75%。该量表可能有助于区分痴呆与正常情况，尤其对65岁以上的患者有用。
