Research has previously linked inflammation to Alzheimer’s disease (AD), yet scientists from Massachusetts General Hospital (MGH) and the Harvard Aging Brain Study (HABS) have made a surprising discovery about that relationship. In a new study published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association, they report that elevated levels of two chemical mediators of inflammation, known as cytokines, are associated with slower cognitive decline in aging adults.
