Sensitivity and specificity of the extended scale for dementia

Arch Neurol. 1988 Aug;45(8):849-52. doi: 10.1001/archneur.1988.00520320035012.


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.
