Among former National Football League players who died with CTE, tau tangles, crumbling white matter, and arteriolosclerosis independently contributed to dementia.
What’s with all those head-to-head comparison studies of academic and commercial biomarker tests? Could we not just pick one that works, and be done?
In a tauopathy model, knocking out C3 spared synapses and neurons. In an amyloidosis model, deleting C3 preserved dendritic spines, but exacerbated plaque growth.
Older people who lived healthy lifestyles had a third lower risk of dementia than their unhealthy peers, but only if their genetic risk for the disease was low.
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.
New PET Staging Scheme for Amyloid? Physical Activity May Shield the Brain from the Onslaught of Aβ Crenezumab Update: Baseline Data from Colombian Prevention Trial Colombian Cohort Delivers Data on Blood NfL Rare Luck: Two Copies of ApoE2 Shield Against ...
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.
The study halted early when the primary endpoint was met, but an unusual trial design and lack of detailed data leave questions unanswered.
Speakers at AD/PD 2019 reported that AD risk factors mess up lipid metabolism in glial cells. In cellular models, speeding the clearance of fats lessened pathology.
Proteomics and protein-protein interaction research may yield clues to etiology, tracking, and treatment of granulin-related and other forms of FTD/ALS.
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.
