A new study have identified which blood tests are best at detecting Alzheimer’s disease during the earliest stages, and another blood test that is optimal for detecting relevant treatment effects. These findings will speed up the development of new...

Credit: Salk Institute Despite decades of research, Alzheimer’s disease remains a debilitating and eventually fatal dementia with no effective treatment options. More than 95 percent of Alzheimer’s disease cases have no known origin. Now,...

A, Plasma concentration time profiles of LEV by dose and sex in 5XFAD males and females. B, One-compartment model fit for the 30 mg/kg dose. C, Volume of distribution (V/F) and clearance (CL/F) is shown....
by Lund University Visual representation of the role of microglia activation in longitudinal accumulation of amyloid and tau aggregates. When microglia are in a homeostatic state, they do not protect against the accumulation of amyloid and tau aggregates, which increase over time in individuals at risk of developing Alzheimer’s disease (AD) (a). In contrast, when...
by Frontiers Credit: Unsplash/CC0 Public Domain Alzheimer’s disease can remain undetected until it is too late to treat. Large-scale screening programs could help to detect early-stage disease, but current diagnostic methods are too cumbersome and expensive. Now, a new study is the first to identify formic acid as a sensitive urinary biomarker that can reveal...

by Washington University School of Medicine Red and orange areas on these heat maps of human brains show where the gene APOE is most active (top two brain images) and where tangles of the protein tau are most concentrated (bottom two brain images). APOE is the biggest genetic risk factor for Alzheimer’s, and tau tangles...
