1. A method of aiding diagnosis of Alzheimer'"'"'s disease (“
- AD”
), comprising;
obtaining a blood sample from a human individual;
comparing normalized measured levels of a group of at least 4 AD diagnosis biomarkers from the individual'"'"'s blood sample to a reference level of each AD diagnosis biomarker;
wherein the group of AD diagnosis biomarkers comprises BDNF, PDGF-BB, Leptin and RANTES;
wherein the reference level of each AD diagnosis biomarker comprises a normalized measured level of the AD diagnosis biomarker from one or more blood samples of human individuals without AD; and
wherein levels of AD diagnosis biomarkers less than the reference level of each AD diagnosis biomarker indicate a greater likelihood that the individual suffers from AD.

Abstract
The inventors have discovered a collection of proteinaceous biomarkers (“AD biomarkers) which can be measured in peripheral biological fluid samples to aid in the diagnosis of neurodegenerative disorders, particularly Alzheimer'"'"'s disease and mild cognitive impairment (MCI). The invention further provides methods of identifying candidate agents for the treatment of Alzheimer'"'"'s disease by testing prospective agents for activity in modulating AD biomarker levels.
