New brain scan detects Alzheimer's tau earlier than current standard

Advanced tau imaging improves early Alzheimer’s disease detection accuracy

A new brain imaging test can detect a key hallmark of Alzheimer's disease before symptoms appear and earlier than the method currently used in clinical practice in the United States and Europe, report University of Pittsburgh School of Medicine researchers today in The Lancet.

Newer Brain Scan Spots Alzheimer's Tau Years Before Symptoms, and Twice as Often

Two radioactive tracers go into the same brain, five weeks apart. They are hunting the same thing: the tangled knots of tau protein that mark out Alzheimer’s disease from the dozens of other conditions that fog the ageing mind. Same person, same stage of disease, same machine humming around the skull. And yet the two scans disagree, sometimes wildly, about whether the tau is even there. That disagreement is the unsettling heart of a study publis…

Breakthrough Brain Scan Identifies Alzheimer’s Tau Protein Earlier Than

A groundbreaking advancement in brain imaging heralds a new era in the early detection of Alzheimer’s disease, uncovering pathological tau proteins well before clinical symptoms arise. Researchers from the University of Pittsburgh School of Medicine have executed a comprehensive, multicenter study that compares two positron emission tomography (PET) tracers—Flortaucipir and MK6240—to determine their efficacy in identifying tau pathology, a pivot…

Detecting Alzheimer’s Early by Brain Scan or Blood

While Alzheimer’s disease accounts for about 60-70% of dementia diagnoses, the timing of these diagnoses occur late in disease progression. Identifying early signs of Alzheimer’s may allow individuals time to address potential risk factors in their lives. “Alzheimer’s disease pathology begins years before symptoms emerge,” said Kristine Yaffe, MD, vice chair in the UCSF Department of Psychiatry and Behavioral Sciences. Yaffe and her team have sp…
