Abstract
Background: The well-established core biomarkers used to identify Alzheimer's disease (AD) overlap with other dementia disorders such as dementia with Lewy bodies (DLB) and Parkinson's disease with dementia (PDD). This study aimed to evaluate whether the cerebrospinal fluid (CSF) amyloid-beta (A beta)(1-42)/A beta(1-40) ratio, measured by a novel method, could improve the differential diagnosis of AD, DLB and PDD. Method: CSF levels of A beta(1-40) and A beta(1-42) in patients with PDD, DLB, AD, Parkinson's disease and controls were analyzed using an amplified luminescent proximity homogenous immunoassay along with conventional immunoassays. Results: The CSF A beta(1-42)/A beta(1-40) ratio increased discrimination of AD from PDD and DLB... (More)

Results: The CSF A beta(1-42)/A beta(1-40) ratio increased discrimination of AD from PDD and DLB compared with either of the two A beta biomarkers individually. Conclusion: The use of the A beta(1-42)/A beta(1-40) ratio could improve the differentiation of AD from PDD and DLB. (C) 2013 S. Karger AG, Basel (Less)
