Dementia signs are in the blood, researchers say

Researchers have reportedly found warning signs that could indicate impending dementia in the blood

MicroRNAs are molecules that regulate and influence the production of proteins and are a central process in metabolism.

Combining the analysis of human data and mechanistic studies in model systems, the study's authors said they identified identify a circulating 3-microRNA signature that reflects key processes associated with the ability of a cell or system of cells to detect perturbation and generate a compensatory response to restore baseline function.
