Plaques, Tangles Throw Off the Brain’s Rhythms
In the human brain, alpha waves fell out of sync, while delta-theta waves swelled in concert with amyloid plaques, neurofibrillary tangles. Alpha modulation correlated with cognitive decline.

The company halted its Phase 2 trial of ABBV-8E12 due to lack of efficacy.
By analyzing a single MRI scan, researchers pinpointed the origin of frontotemporal dementia pathology and predicted its future progression.
DAPPD suppressed neuroinflammation and preserved cognition in mouse models of amyloidosis, suggesting potential for treating Alzheimer’s disease.
In a mouse tauopathy model, knocking out the NLRP3 inflammasome prevented toxic tau from forming.
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?
New study finds no uptick in herpes viruses in AD. If herpes plays a role, it says, then probably it acts as an early trigger of pathology.
With experiments and careers on hold, scientists working from home are turning to virtual lab meetings and journal clubs to keep up morale.
Data shown at AAT-AD/PD explain why the DIAN-TU trial missed its primary endpoint. But gantenerumab strongly reduced plaques, tau, phospho-tau, and slowed NfL. This result prompted an open-label extension, sustaining hope for efficacy.
Hippocampal imaging and fluid markers of BBB damage found in ApoE4 carriers.
According to a structural analysis, fluorescently tagged tau fragments cannot form paired helical filaments. This suggests the assay does not measure prion-like propagation.
When these tiny mural cells carried APOE4, they secreted more ApoE, causing Aβ to deposit in capillary walls. Blocking ApoE production prevented angiopathy.
Live imaging of mouse brain reveals that microglia quickly engulf cell bodies while astrocytes dispose of the neuron’s more distal reaches. The cleanup crew tires with age.
Single-nucleus transcriptomics of postmortem AD brain and mouse models of amyloidosis hammers home the species-specific responses of microglia to Aβ pathology.
Co-sponsors Banner, Novartis, and Amgen announced that they will stop testing CNP520 in two Phase 2/3 studies in people at risk of AD. The drug worsened cognition.
