Several neuropsychological tests to assist dementia diagnosis in low education elderly population
Objective: ScnsitMty and specificity of several psychometric tests were evaluated to provide practical instruments tor dementia diagnosis in low educational population. Method: A total of 3244 residents aged 55 ycars and over were drawn through a stratified multiple cluster sampling, 62 percent were illiterate or have elementary education. Door to door screening to all participants were conducted in phase 1 using Chinese version of Mini-Mental State Examination (CMMSE), then followed up and identified dementia through a set of diagnostic examination in phase Il .

Result: Specificity of FOM and RVR were more than 94% in all groups while Sensitivity were between 52-78%. Specificity of BD and DS were between 72-85% and 78-98% respectively. Specificity of BD and DS have tendency to increasing while sensitivity of BD and DS declined obviously with increasing of educationievel. Specificity of series test was more than 97% except for BD and DS. Conclusion: Sensitivity and specificity of FOM amd RVR were good in different education group.
