Study finds blood test for Alzheimer’s detection in Down syndrome patients

August 25, 2022

A new study led by Lund University in Sweden has found that a blood test can accurately identify Alzheimer’s disease in Down syndrome patients.

In the study, which was published in JAMA Neurology, a blood biomarker was compared with PET imaging results to find whether people had significant amounts of proteins, such as tau and amyloid aggregates, that can indicate Alzheimer’s disease accumulated in the brain.

It involved 300 Down syndrome patients, with 40% showing signs of Alzheimer’s disease onset.
