Belgium Validates Blood Tests for Alzheimer's Diagnosis, Matching Lumbar Puncture Accuracy

Blood tests detecting amyloid and tau biomarkers have been clinically validated in Belgium since May, offering a faster, less invasive alternative to lumbar puncture for Alzheimer's diagnosis. The tests show concordance rates close to lumbar puncture, enabling earlier detection and reassuring patients with non-Alzheimer memory issues. This marks a shift in diagnostic practice, though broader clinical adoption and reimbursement details remain uncertain.
