Recent breakthroughs in blood-based biomarkers of Alzheimer disease: opportunities and challenges in older adults.
Blood tests for Alzheimer's disease components are becoming faster and more practical for routine clinical diagnosis, even in older patients with other conditions.
This Age and Ageing review synthesized recent advances in blood-based Alzheimer's biomarkers including phospho-tau species and amyloid ratios, evaluating diagnostic accuracy and practical utility specifically in older adults with comorbidities. The review identifies translational challenges while highlighting rapid progress making blood-based AD diagnosis increasingly feasible in routine clinical care.
