A recent study led by King’s College London reveals that the biological markers for Alzheimer’s disease are significantly more common in adults over 85 years old than earlier estimates suggested. By utilizing a non-invasive blood test to identify specific protein deposits, researchers found that these indicators were less frequent in younger seniors and individuals with higher education levels. The data notably contradicts the long-held assumption that the condition is more prevalent in women, showing no significant gender differences across age groups. Furthermore, the findings indicate that over ten percent of people older than 70 could qualify for new monoclonal antibody treatments designed to slow cognitive loss. This research underscores the potential of blood-based biomarkers to revolutionize early detection and large-scale screening for dementia in aging populations.
