Loss of ataxin-1 intensifies BACE1 expression, Alzheimer’s pathogenesis. Is that how ataxin GWAS variants increase AD risk?
Smartphones and gamified apps move cognitive testing from the lab into the real world. But keeping people engaged remains a problem. Is passive monitoring the answer?
Passive monitoring of old people in their everyday lives is starting to generate new indicators for cognitive impairment.
The Phase 2 study missed its primary endpoint. While fewer developed dementia in the treatment group, the effect was not statistically significant. People on drug had less brain atrophy than those on placebo.
A plasma assay for Alzheimer’s could radically speed up screening for clinical trials; alas, competing assays don’t measure the same thing.
At AAIC, researchers touted phospho-tau species, especially p217 and p181. They tick up in CSF as an early response to amyloid accumulation.
At this year’s AAIC, no sooner had scientists reported that phospho-tau in the CSF might reflect early responses to amyloid, than they reported parallel data for phospho-tau in blood.
Protein levels track with cognitive function and can distinguish Alzheimer’s patients from controls.
Changes in the composition of the cerebrospinal fluid and synapses may reveal novel insights into AD pathology.
In patient-derived neurons, tau mutations scupper lysosomes and SORLA shunts APP through different types of endosomes.
