Clinical Trial Summary

To establish a cutoff value using a ratio of CSF tau to Aβ42 (tau/Aβ42) for distinguishing patients wth mild to moderate Alzheimer's disease (AD) from health elderly control subjects. The investigators hypothesize that a cutoff can be found that has at least 80% sensitivity and 60% specificity.


Clinical Trial Description

This study will enroll 50 AD subjects, 50 normal controls and approximately 20 subjects with non-AD dementia. There will be 2 visits (up to 30 days apart), and a telephone follow-up visit.

This protocol does not include treatment of subjects. Lumbar puncture and phlebotomy are routine clinical tasks and are associated with a low level of risk. All adverse events will be documented and reviewed by the PI. ;
