Blood Test Gives Alzheimer’s Diagnosis With 90% Accuracy: Study

The New York Times: A Blood Test Accurately Diagnosed Alzheimer’s 90% Of The Time, Study Finds 
Scientists have made another major stride toward the long-sought goal of diagnosing Alzheimer’s disease with a simple blood test. On Sunday, a team of researchers reported that a blood test was significantly more accurate than doctors’ interpretation of cognitive tests and CT scans in signaling the condition. The study, published Sunday in the journal JAMA, found that about 90 percent of the time the blood test correctly identified whether patients with memory problems had Alzheimer’s. Dementia specialists using standard methods that did not include expensive PET scans or invasive spinal taps were accurate 73 percent of the time, while primary care doctors using those methods got it right only 61 percent of the time.

NPR: A Protein Called Reelin May Help Protect Brains Against Aging And Alzheimer’s
A key protein that helps assemble the brain early in life, also appears to protect the organ from Alzheimer’s and other diseases of aging. A trio of studies published in the past year all suggest that the protein Reelin helps maintain thinking and memory in ailing brains, though precisely how it does this remains uncertain. The studies also show that when Reelin levels fall, neurons become more vulnerable. (Hamilton, 7/29)

But little evidence supports the use of these “tongue-tie releases” for most babies, according to a report published on Monday by the American Academy of Pediatrics, which represents 67,000 doctors. The tongue procedures, which often cost several hundred dollars, should be done only to the small fraction of infants with severely tethered tongues, the report said. (Kliff, 7/29)
