In the Alzheimer’s brain, too, plaques trigger a coordinated inflammatory response from microglia and astrocytes. A preprint paper had shown the same for mice.
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.
A slight drop in hospital admissions after amyloid PET, especially in people with positive scans, fell well short of the prespecified endpoint. Still, IDEAS is broadening into a research platform, and IDEAS 2 will add racial diversity.
In updating their broad evaluation of the risk literature, the commission blamed three more modifiable factors for causing 6 percent of all dementia, concluding that 40 percent of cases can be prevented.
