Scientists Close In On Blood Test For Alzheimer’s

pgmrdlm shares a report from CBS News: Scientists are closing in on a long-sought goal — a blood test to screen people for possible signs of Alzheimer’s disease and other forms of dementia. On Monday at the Alzheimer’s Association International Conference, half a dozen research groups gave new results on various experimental tests, including one that seems 88% accurate at indicating Alzheimer’s risk. Doctors are hoping for something to use during routine exams, where most dementia symptoms are evaluated, to gauge who needs more extensive testing. Current tools such as brain scans and spinal fluid tests are too expensive or impractical for regular check-ups. Dr. Richard Hodes, director of the National Institute on Aging, called the new results “very promising” and said blood tests soon will be used to choose and monitor people for federally funded studies, though it will take a little longer to establish their value in routine medical care. “In the past year we’ve seen a dramatic acceleration in progress” on these tests, he said. “This has happened at a pace that is far faster than any of us would have expected.”
