Years before tau tangles show up in brain scans of patients with Alzheimer's disease, a biomarker test developed at the ...

Researchers say CSF biomarker test correlates with the severity of cognitive decline, independent of other factors, including brain amyloid deposition.

is the amyloid-beta (Aβ) plaque, which could not be detected during life until recently. Advances have permitted its detection in cerebrospinal fluid and with positron emission tomography (PET ...

This finding suggests that a single positron emission tomography (PET) scan assessing amyloid beta protein levels in the brain could be sufficient to predict the rate of cognitive decline in ...

Years before tau tangles show up in brain scans of patients with Alzheimer's disease, a biomarker test developed at the University of Pittsburgh School of Medicine can detect small amounts of the ...

(HealthDay News) — Appropriate use criteria (AUC) for the use of amyloid and tau positron emission tomography (PET) have been issued by the Alzheimer’s Association and the Society for Nuclear Medicine ...

A new biomarker test developed at the University of Pittsburgh could help doctors doctors detect signs of Alzheimer's years sooner, according to research published Monday in Nature Medicine.

Taking longer to reach the rapid eye movement (REM) stage of sleep could mean you are more likely to develop dementia.

including both amyloid-beta and tau deposition," they wrote. Lee and colleagues assessed 208 cognitively unimpaired people who had baseline amyloid PET scans; of these, 192 completed both baseline ...

This study adds to the growing evidence that Alzheimer’s disease may start long before traditional symptoms appear. The fact ...

Alzheimer’s disease (AD) is the most common form of dementia in the elderly. Although the prevalence of AD increases with age, studies have indicated that a number of elderly patients have AD ...
