CLA recent study published in the scientific journal The Lancet has introduced a promising blood test capable of detecting early biological signs of Alzheimer’s disease years before a clinical diagnosis. The research focused on individuals around 61 years old in the United States, analyzing blood samples for proteins associated with Alzheimer’s—beta-amyloid and phosphorylated tau. These proteins are known to accumulate in the brain during the early stages of the disease. Participants also underwent cognitive tests assessing memory, processing speed, executive function, and overall cognitive performance. Results showed that those with positive biomarkers in their blood performed slightly worse in certain cognitive tasks and experienced faster decline in verbal memory and processing speed over five years. This suggests that some people in their 60s already show subtle biological indicators of Alzheimer’s, which could allow for earlier intervention strategies to reduce risk factors before the disease progresses significantly.
