Despite plaques and tangles in the brain, this group, on average, maintains their cognitive skills over two to four years, suggesting the presence of resilience factors.
Among 14 familial Alzheimer’s APP mutations, two don’t change the Aβ42/Aβ40 ratio, but all of them yield long peptides of 45 to 49 residues that hide out in the membrane.
New genetic variants emerged by harmonizing whole-exome-sequencing data across continents, and by using imputation to plumb the depths of existing GWAS. One variant encodes a microglial phospholipid transporter.
Researchers split $200,000 for their theories on the role of six microbes—one virus, four bacteria, and one parasite—in Alzheimer’s.
At AAT-ADPD, researchers report how they built on prior reports that a person’s blood level of p-tau181 tells if they have Alzheimer’s.
The first topline Phase 2 results from an antibody targeting Parkinson’s pathology, Roche’s prasinezumab, were a mixed bag. Next steps are unclear.
Subtle memory deficits resolved after volunteers stopped taking the Novartis BACE inhibitor.
