The results, published in the journal Cell & Bioscience, are based on the analysis of blood samples from 192 people with mild cognitive impairment and risk of developing Alzheimer’s disease.

The experts identified 15 non-coding small RNA molecules, present in 85% of people most at risk of developing the disease, which would make it possible to diagnose the most vulnerable patients years in advance.

The experts detailed that these potential molecules are short nucleotide chains that, despite containing genetic information, do not have the capacity to encode a protein.

The authors of the study said the molecules have the potential to improve the prediction of Alzheimer’s disease and its early diagnosis.
