At HAI 2020, scientists more precisely quantified the relationship between plaques, tangles, and cognitive decline.
By engaging scientists studying every tau-based disorder, a new conference aimed to foster collaborations and research directions.
Two papers report that phosphorylated tau in the blood distinguishes people with AD from healthy controls and from people with frontotemporal and vascular dementias.
Brain imaging and cognitive tests may be the gold standards for tracking AD progression, but clinical trials using these procedures are expensive, risky, and time-consuming...
At the HAI 2020 conference, the tracers PI-2620 and APN-1607 appeared to bind frontotemporal dementia tau. MK-6240 looked highly sensitive. And JNJ-067 and SNFT-1 are two new kids in town.
The tracer distinguished people with progressive supranuclear palsy from controls with a sensitivity of 85 percent, suggesting potential as a diagnostic for 4R tauopathies.
A slight drop in hospital admissions after amyloid PET, especially in people with positive scans, fell well short of the prespecified endpoint. Still, IDEAS is broadening into a research platform, and IDEAS 2 will add racial diversity.
The AAT-AD/PD conference hosted a virtual conversation about what the trial’s disappointing cognitive and tantalizing biomarker data might mean. Hidden between thank you’s and pledges to stay committed were substantive points of debate and context.
In 2,144 Colombian ADAD family members, plasma NfL in gene carriers rises as early as two decades before their symptoms start.
The FDA has prioritized review of C2N’s blood test for amyloid-β. A pivotal clinical trial will correlate the test with amyloid PET scans.
With plasma tests performing in AIBL staging, scientists are sharing data across platforms and cohorts, and tackling standardization to avoid time lost to irreproducibility.
Two papers report that skin samples from people with Parkinson’s disease contain α-synuclein seeds that can be robustly amplified, paving the way for a reliable test for the disease.
One of the most coveted achievements AD researchers are striving for these days is to develop a biomarker that could, simply and inexpensively, detect if a person has early Alzheimer's disease...
A plasma assay for Alzheimer’s could radically speed up screening for clinical trials; alas, competing assays don’t measure the same thing.
New synaptic profiling and imaging techniques are enabling scientists to zero in on synaptic proteins, including phospho-tau, that make the difference between clinical Alzheimer’s and resilience.
