Researchers have identified RNA biomarkers, known as “SECmeres”, that could provide a simple blood test for earlier Alzheimer's diagnosis (opens in new tab)

Several brain-derived extracellular vesicles and particles (EVPs) cross the blood brain barrier and reach circulation. Mount Sinai researchers have identified brain-specific RNA biomarkers in blood, paving a way for early and easier diagnosis of Alzheimer’s disease. Photo courtesy of Nature Communications.
