Simple blood test may detect Alzheimer’s

A simple blood test that can predict the onset of Alzheimer’s disease before recognisable symptoms appear could be available in two years, say scientists.

The test, likely to cost €140 to €400, can show with almost 90% accuracy which individuals suffering from mild memory loss are going to develop Alzheimer’s within a year.

It is expected to transform the search for treatments for the devastating brain illness that affects around thousands of people a year in Ireland.
