A team of Canadian scientists has been able to identify biomarkers that can help detect early 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.
Dr. Liang Li, a professor of chemistry at the University of Alberta, Canada, said: "By examining saliva samples from three groups of patients with Alzheimer's disease, D & # 39; A moderate cognitive impairment and normal cognition, Canadian scientists have examined more than 6,000 compounds.Metabolic processes forming part of the metabolic processes in the body – to determine any change or divergence between groups.
"In this analysis, we found three receptors that could be used to distinguish these three groups," said Li Li. "This is preliminary because we used a very small sample size, but the results are promising. If we can use a larger number of samples, the validity of our results and the development of the saliva test for Alzheimer's disease are very accurate.In addition, the identification of these biomarkers is the ability to test the effectiveness of treatments.
