A team of Canadian scientists has been able to identify biomarkers that can help detect early moderate cognitive impairment and Alzheimer's disease by badyzing saliva samples.
The developed saliva test demonstrates its benefits in clinical conditions by its softness and non-invasiveness, as well as its ability to detect degenerative neurological diseases, allowing early intervention.
Dr. Liang Li, professor of chemistry at the University of Alberta, Canada, examined saliva samples from three groups of patients with Alzheimer's disease, moderate cognitive impairment, and of natural cognition. Canadian scientists have tested more than 6,000 metabolic compounds. Which are part of the metabolic processes in the body, to identify any change or divergence between groups.
"In this badysis, 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.
