Neurology 2011;77:227–2349 / Canadian / 65+ / 5 / 19 frailty variables (self-rated health, problems with eyesight, hearing, denturefit, stomach, kidneys, respiratory function, skin, bladder & bowel control, orthopaedic problems, and others) / 0.64
10 / 0.66
Published dementia risk scores were selected according to the following criteria: longitudinal studies with dementia as outcome, risk models including multiple health-related variables, and reporting AUC or C statistic. Studies focusing on risk estimation in patients with MCI, or on cognitive tests, neuroimaging or cerebrospinal fluid measurements without health-related variables, were not included here.Abbreviations: 3MS, Modified MMSE; AUC, area under the curve; APOE, apolipoprotein E gene; CAIDE, Cardiovascular Risk Factors, Aging and Dementia study; CES-D, Center for Epidemiologic Studies-Depression Scale; DSST, Digit Symbol Substitution; EKG, electrocardiogram; MMSE,Mini-Mental State Examination; SBP, systolic blood pressure;TBI, traumatic brain injury;WML, white matter lesions.
