Finger-prick blood test could speed Alzheimer's diagnosis in international trial
An international trial enrolling about 1,000 volunteers over 60 in the UK, US and Canada is testing whether a simple finger-prick blood test can detect Alzheimer's-related biomarkers to diagnose the disease more quickly and non-invasively, potentially replacing or reducing reliance on expensive brain scans and lumbar punctures; results are expected in 2028.
