  "account": "Alzheimer's disease is typically associated with the accumulation of amyloid plaques and tau protein tangles, but brain inflammation may initiate the process years before cognitive decline becomes apparent. A new study presents evidence that two distinct inflammatory proteins in the blood—YKL-40 and GFAP—signal two separate paths of brain damage that eventually result in memory problems. The research, published in Alzheimer's & Dementia, suggests that brain inflammation may serve as an early trigger in the disease rather than just a reaction to it.",
  "summary": "A new study reveals that two different inflammatory proteins in the blood signal separate types of brain damage. Both distinct pathways ultimately converge to fuel Alzheimer's-related tau tangles, brain shrinkage, and memory decline in older adults.",
