Control group was divided into <60 years and >/=60 years. Alzheimer's disease group was divided into Mini-Mental State Examination (MMSE) >/=21 and MMSE <21.Test: The DemTect includes five short, easy to administer tasks that are sensitive for diagnosing dementia (word list; delayed recall of word list; number transcoding; semantic word fluency task; digit span reverse).Diagnostic standard: Full clinical assessment plus CDR to assess dementia and Peterson criteria to assess mild cognitive impairment.Outcomes: Sensitivity and specificity of DemTect and MMSE inClassifying people with mild to moderate Alzheimer's disease and mild cognitive impairment compared with full clinical assessment.MAIN RESULTS:The transformed total DemTcct score is independent of age and education and performed well when compared with MMSE. At a DemTect cut off score of 13, overall classification rate, sensitivity and specificity were high (see table 1; score of 13-18 represents appropriate cognitive power for age). Additional cut off scores were useful for predicting mild cognitive impairment and dementia (mild cognitive impairment; 9-12 points; dementia: 0-8 points; total classification rate: 85.4%).CONCLUSIONS:The DemTect is a useful scale for identifying mild cognitive impairment and early dementia in older adults. It is easy to administer and accepted well by participants. pubtype: Academic Journal doctype: abstract commentary tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
