Abstract

Background: Detection of any cognitive impairment is mandated as part of the Medicare annual wellness visit, but screening all patients may result in excessive false positives. Methods: We developed and validated a brief Dementia Screening Indicator using data from four large, ongoing cohort studies (the Cardiovascular Health Study CHS ; the Framingham Heart Study FHS ; the Health and Retirement Study HRS ; the Sacramento Area Latino Study on Aging SALSA ) to help clinicians identify a subgroup of high-risk patients to target for cognitive screening. Results: The final Dementia Screening Indicator included age (1 point/year; ages, 65-79 years), less than 12 years of education (9 points), stroke (6 points), diabetes mellitus (3 points), body mass index less than 18.5 kg/m2 (8 points), requiring assistance with money or medications (10 points), and depressive symptoms (6 points). Accuracy was good across the cohorts (Harrell's C statistic: CHS, 0.68; FHS, 0.77; HRS, 0.76; SALSA, 0.78). Conclusions: The Dementia Screening Indicator is a simple tool that may be useful in primary care settings to identify high-risk patients to target for cognitive screening. 2014 The Alzheimer's Association.
