It was much more accurate than primary care doctors using cognitive tests and CT scans. The findings could speed the quest for an affordable and accessible way to diagnose patients with memory problems.<\/p>\n

Scientists have made another major stride toward the long-sought goal of diagnosing Alzheimer\u2019s disease with a simple blood test<\/a>. On Sunday, a team of researchers reported that a blood test was significantly more accurate than doctors\u2019 interpretation of cognitive tests and CT scans in signaling the condition.<\/p>\n

The study<\/a>, 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\u2019s. 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.<\/p>\n

\u201cNot too long ago measuring pathology in the brain of a living human was considered just impossible,\u201d said Dr. Jason Karlawish, a co-director of the Penn Memory Center at the University of Pennsylvania who was not involved in the research. \u201cThis study adds to the revolution that has occurred in our ability to measure what\u2019s going on in the brain of living humans.\u201d<\/p>\n

The results, presented Sunday at the Alzheimer\u2019s Association International Conference in Philadelphia, are the latest milestone in the search for affordable and accessible ways to diagnose Alzheimer\u2019s, a disease that afflicts nearly seven million Americans and over 32 million people worldwide. Medical experts say the findings bring the field closer to a day when people might receive routine blood tests for cognitive impairment as part of primary care checkups, similar to the way they receive cholesterol tests.<\/p>\n<\/div>\n<\/div>\n

\u201cNow, we screen people with mammograms and PSA or prostate exams and other things to look for very early signs of cancer,\u201d said Dr. Adam Boxer, a neurologist at the University of California, San Francisco, who was not involved in the study. \u201cAnd I think we\u2019re going to be doing the same thing for Alzheimer\u2019s disease and hopefully other forms of neurodegeneration.\u201d<\/p>\n

In recent years, several blood tests have been developed for Alzheimer\u2019s. They are currently used mostly to screen participants in clinical trials and by some specialists like Dr. Boxer to help pinpoint if a patient\u2019s dementia is caused by Alzheimer\u2019s or another condition.<\/p>\n
