Abstract
Objective: To investigate whether cerebrospinal fluid (CSF) biomarkers can predict cognitive decline in healthy, elderly individuals as they have been shown to do in cognitively impaired patient samples. Methods: In this study, 57 controls were tested for CSF biomarkers at baseline and then cognitively followed over 3 years. Results: Low levels of baseline beta-amyloid 1 - 42 (A beta 42) were associated with development of subjective memory impairment affecting quality of life (memQoL), with a worse Mini Mental Status Examination score and with inability to live in regular housing at follow-up ( p < 0.05). The combination of baseline A beta 42 and phosphorylated tau (P-tau) was found to predict development of pathological memQoL with a... (More)

The combination of baseline A beta 42 and phosphorylated tau (P-tau) was found to predict development of pathological memQoL with a sensitivity of 71.4% and a specificity of 75.7 (< 0.01). Conclusion: Low A beta 42 and combined A beta 42 and P-tau predicted subjective cognitive decline in healthy individuals. In summary, this study shows that already in the clinically normal population Alzheimer-disease-related biological signs might be detectable. Copyright (c) 2007 S. Karger AG, Basel. (Less)
