A Possible Blood Test for Alzheimer’s Disease
12 March 2012
JUNE SIMMS: This is SCIENCE IN THE NEWS, in VOA Special English. I’m June Simms.
SHIRLEY GRIFFITH: And I’m Shirley Griffith. Today we tell about Alzheimer’s disease. More than a century after its discovery, Alzheimer’s disease is still destroying people’s brains. There is no known cure. But research may offer hope for the future.
(MUSIC)
JUNE SIMMS: Alzheimer’s disease affects memory and personality - the qualities that make people individuals. The disease robs their ability to perform simple activities like putting on clothing or even swallowing. People with the condition begin to forget simple things, like where they left the key to their car. As time passes, they forget more and more. They may forget what a key is used for.
Victims of Alzheimer’s can forget the names of their husbands, wives or children. Then they forget who they are. Finally, they remember almost nothing. It is as if their brains die before the other parts of the body.
Alzheimer’s patients do die from its effects or conditions linked to it. But death may not come for many years.
SHIRLEY GRIFFITH: An estimated thirty million people around the world have Alzheimer’s disease. Alzheimer’s affects people of all races equally. Women are more likely to develop the disease than men. This is partly because women generally live longer than men.
