Blood test coming to diagnose Alzheimer’s disease?

A research team has found a method to detect biomarkers of Alzheimer’s disease in blood platelets. The test uses a ratio between normal and abnormal brain tau proteins to identify those with Alzheimer’s disease and other neurodegenerative conditions.

The researchers found that the presence of abnormal tau proteins corresponds with decreased brain volume in parts of the brain where characteristics of Alzheimer’s appear.

A non-invasive test for Alzheimer’s disease would help detect people at risk before symptoms develop, and make prevention and early treatment possible.

A study published in the Journal of Alzheimer’s Disease in 2016 described using levels of the protein clusterin to ascertain which dementia patients are at risk of Alzheimer’s. Also, a 2015 study focused on using metabolites in saliva to detect cognitive impairment.

In 2016, 5.4 million Americans were affected by Alzheimer’s disease. For more information, consult the Alzheimer’s @Guide To Long Term Care.
