By pinpointing where tau pathology starts in a person’s brain, researchers better predicted future spread and determined small changes in tangle load.
In a retrospective study, people with vitiligo had 12 times the risk of developing Alzheimer’s disease than did healthy controls. Why is that?
Restoring proper gene editing assuaged mitochondrial defects in patient-derived neurons and organoids. Splicing errors may underlie other PD cases as well.
The day-long advisory committee meeting will be broadcast live online. Prerecorded presentations are to be available November 4; the public can submit comments.
A recent genetics symposium drew positive reviews for its approach of following up prerecorded, on-demand talks with a live Q&A session.
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.
Reducing levels of monounsaturated fatty acids lowered α-synuclein toxicity and prevented movement symptoms in mice. Scientists say the data boost the α-synuclein tetramer hypothesis.
Armed with snazzy new hardware, scientists solve protein structures to a resolution of 1.22Å. Cryo-EM now rivals X-ray crystallography.
Three amino acid substitutions in the Aβ sequence accelerate BACE cleavage of APP and ramp up Aβ production in rats and mice. The mice can serve as better controls for mutant APP knock-ins already in use.
Simple lifestyle factors such as alcohol consumption and stool quality alter gut flora. Research on the microbiome and disease should account for those factors, a study reports.
The anti-Aβ biologic will be put to the test in two stages of preclinical Alzheimer’s, designated by amyloid load. The long-dormant “est” PET tracer, NAV4694, is on board to make sensitive measurements.
At CTAD, a Phase 2 open-label extension of this anti- Aβ protofibril antibody posted data as expected, and new Phase 3 trials for people with early and preclinical Alzheimer’s were described.
After years of building an online registry, designing selection algorithms, and getting sites up and running, COVID-19 nearly derailed this trial-ready cohort once again. Now, the first participants have reached the final queue.
Remote assessments on a smartphone closely matched tests taken in the clinic. They also may detect slip-ups in learning—an earlier cognitive deficit that arises in preclinical AD.
After missing primary endpoints in Alzheimer’s trials, this p38 MAPKa inhibitor gained some traction in a test in people with DLB.
