WebThe ratio of T-tau/Abeta1-42 at baseline yielded a sensitivity of 85.3% for detection of AD and the specificity was 84.8% to differentiate controls and nAD dementia. Conclusion: Our findings confirm the use of T-tau/Abeta1-42 ratio in the discrimination of AD patients from all other patients. Publication types WebRESULTS: Individuals with very mild or mild AD have reduced mean levels of CSF Abeta(42) and increased levels of CSF tau and phosphorylated tau(181). Cerebrospinal fluid Abeta(42) level completely corresponds with the presence or absence of brain amyloid (imaged with Pittsburgh Compound B) in demented and nondemented individuals.
