Data from different next-generation tracers look similar. It shows spreading plaques kick off tangles by Braak region; memory starts slipping later.
NIH Summit Sets Agenda for AD-Related Dementias Alzheimer's Disease Research Summit 2019 ...
Happy New Year, readers! Yes, 2019 has passed, but so much happened last year that capturing the essence took longer than usual. Our mega year-end story is now posted for your reading pleasure.
A half-dozen lesser-known compounds in trials for Alzheimer’s disease posted results at the CTAD conference.
Bringing the total NIH funding for Alzheimer’s research up to $2.8 billion, the Senate continued its steady upward climb in spending for the disease.
Apabetalone, an epigenetic drug that tamps down vascular inflammation, slowed cognitive decline in people with MCI. A new statistical analysis of results from AMBAR claimed the plasma-exchange therapy might boost cognition by removing pathogenic proteins from blood.
At CTAD, researchers discussed possible paths forward. One option: exploring whether low doses prevent plaque accumulation while avoiding the cognitive side effects.
Plaque-busting antibodies reset the time course of amyloid accumulation, but so far provide only hints of a clinical benefit in mild AD. Good news: once gone, plaque stays gone for a while.
Using mass spectrometry to detect teensy amounts of phospho-tau species in plasma, researchers reported that p-tau-217 and p-tau-181 picked out people with Aβ pathology. Differences between groups appear to be huge. An MS-based test for plasma Aβ42 corresponded to brain amyloid, and is going in for regulatory approval.
An expanded set of CSF biomarkers exposed tight connections between p-tau, synaptic dysfunction, and neuroinflammation in people with brain amyloid.
Biogen researchers claim the antibody worked in people who got enough of it. To other researchers, the signal validates the amyloid hypothesis and injects fresh energy into the field. But is this interrupted dataset enough to approve?
Prior research has focused on microglia interacting with synapses. New data show they also deal directly with the neuronal cell body. Like little conference rooms, specialized junctions host this communication.
In PASSPORT study, the antibody failed to slow progressive supranuclear palsy. Alzheimer’s trial to continue.
Exposure, Exposure, Exposure? At CTAD, Aducanumab Scientists Make a Case Fluid AD Biomarkers Link P-Tau to Synapses, Inflammation Blood Tests of Phospho-Tau, Aβ42, Track With Brain Amyloid Amyloid Clearance: Check. Cognitive Benefit: Um … Maybe. Picking ...
Researchers link age-related weakening of the barrier to TGFβ signaling, hyperexcitation, and cognitive problems. In rodents, TGFβ antagonists attenuate these effects, reducing seizures.
