The New York Times says researchers “reported that a blood test was significantly more accurate than doctors’ interpretation of cognitive tests and CT scans in signaling” Alzheimer’s disease. The study “found that about 90% of the time the blood test correctly identified whether patients with memory problems had Alzheimer’s,” while “dementia specialists using standard methods that did not include expensive PET scans or invasive spinal taps were accurate 73% of the time” and “primary care doctors using those methods got it right only 61% of the time.” The findings were published in JAMA and presented at the Alzheimer’s Association International Conference.
