Swedish Researchers Find Test For Predicting Alzheimer's

[From article]
simple blood test to identify if men have lost crucial genetic material in later life could finally close the gap in life expectancy between men and women, scientists believe.
New research shows that when men lose their Y sex chromosome they are hundreds of times more likely to develop Alzheimer’s disease.
Previous research has shown that smoking hugely increases the risk of losing the Y chromosome, suggesting that the missing genetic material may also be linked to cancer.
It is thought that Y chromosome is crucial for the normal function of the immune system and without it the body struggles to eliminate cancerous cells, and amyloid plaques in the brain which cause Alzheimer’s disease.
Now scientists at Uppsala University in Sweden have found it is possible to test for loss of the chromosome in a breakthrough which could lead to widespread screening which could pick up which men are at risk so that early health interventions could be made.
"The addition of testing in the general population could give medical practitioners the possibility of using preventive strategies in men at risk,” said lead author Prof Lars Forsberg of Uppsala University.

Although there are presently no cures for Alzhiemer’s disease it is known that lifestyle changes such as eating well, exercising, and brain training can ward off early symptoms if spotted early.

The findings were published in the American Journal of Human Genetics.
