Test spots Alzheimer’s 20yrs earlier

A revolutionary new blood test could diagnose Alzheimer’s 20 years before symptoms appear.

Typically, the disorder is only confirmed by the presence of plaques found in the brain after a person dies.

But the inexpensive blood ood test could show whether these telltale signs are present decades before they suffer any cognitive impairment.

The test works by measuring a protein that indicates whether a person has the disease.

This discovery, made at Lund University in Sweden, could change the way patients are diagnosed and treated.
