Early-Stage Study Finds Possible Link Between Biomarkers in Saliva and Alzheimer’s Disease


(NEW YORK) — New early-stage research presented at the Alzheimer’s Association International Conference on Sunday linked a series of biomarkers in human saliva to a possible test — in the future — for Alzheimer’s Disease.

Researchers at the University of Alberta in Canada discovered the biomarkers, saying that the potential test, which could take years to create, could potentially predict future development of mild cognitive impairment and Alzheimer’s in cognitively intact individuals. The study’s authors evaluated saliva specimens from 108 individuals who were involved in a study on human aging.

The patients were then divided into three groups — those who aged normally, those with mild cognitive impairment and those with Alzheimer’s. Particular substances in the latter two groups could one day be used to point to worse memory performance, researchers speculate.
