📍 How it ended
Blood tests, including the FDA-approved versions and Roche Holding AG's CE-marked Elecsys pTau 217, were developed to detect Alzheimer's before symptoms worsen. While specific blood proteins and RNA biomarkers showed potential for early identification, access to these tests remained limited.

The brief
Researchers and medical providers are utilizing specific blood proteins to identify dementia risk significantly earlier than traditional diagnosis methods. This includes the use of the pTau 217 blood test and the exploration of SECmeres as potential RNA biomarkers.
Coverage from ScienceAlert and Medical Daily emphasizes the ability to detect the disease before symptoms worsen, while highlighting that access to FDA-approved tests remains limited. Reports from Ad-hoc-news.de and UAB Barcelona note the transition to plasma-based diagnosis and the potential for early-stage detection.
Future developments involve the continued evaluation of biomarkers, such as the comparison between SECmeres and extracellular vesicles as reported by Nature.
