Development of a saliva test for the diagnosis of advanced cases of Alzheimer's

A team of Canadian scientists has been able to identify biomarkers that can help detect early moderate cognitive impairment and Alzheimer's disease by analyzing saliva samples.

The saliva test develops its benefits in clinical conditions because of its softness and non-invasiveness, as well as its ability to detect degenerative neurological diseases, allowing early intervention.

"By examining saliva samples from three groups of patients with Alzheimer's disease, a moderate cognitive impairment and a normal perception, Canadian scientists have tested more than 6,000 metabolic compounds "said Dr. Liang Li, professor of chemistry at the University of Alberta. Be part of the metabolic processes in the body to determine any changes or discrepancies between groups. "

"In this analysis, we found three receptors that could be used to distinguish these three groups.This is preliminary because we used a very small sample, but the results are promising.If we can use a larger number of samples , we will be able to validate our results and develop saliva tests for Alzheimer's disease, In addition, the identification of these biomarkers is the ability to test the effectiveness of treatments.
