A blood test that can detect signs of Alzheimer's up to 20 years before the onset of symptoms is a step closer to being developed, according to scientists in the US.

Researchers in St Louis have discovered a way to measure how much of the damaging protein linked to the disease has built up on the brain.

They say the test is 94% accurate when taking age and genetic risk factors into account; after 65, the chances of developing dementia doubles every five years.

And then what? Worry for the next 20 years, pray for a cure? 

I guess it would give you/your family time to make a plan regarding care and finances.
