Blood Biomarkers from Internal Jugular Vein for the Diagnosis of Alzheimer's Disease
This observational study is testing whether blood drawn from the internal jugular vein in the neck gives more accurate Alzheimer's biomarker readings than blood drawn from the standard arm vein. Researchers think brain-draining blood may carry stronger signals of disease. No phase is specified because this is not a drug or treatment trial — it is a diagnostic accuracy study, meaning no intervention is being given.
