Middle-aged WTC responders have cognitive problems, which correlate not only with their PTSD symptoms and exposure to toxic dust, but also with biomarkers of amyloid and tau.
Functional connections between two brain regions are the strongest indicator that pathologic, accumulated tau will spread from one to another.
When observed over an eight-year period, people with the highest plasma concentrations were more likely to die than people with lower levels.
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.
Aβ oligomers latch onto adrenergic receptors, mobilizing a kinase that phosphorylates tau. Blocking adrenergic signaling wards off memory problems in amyloidosis mice.
