Peripheral inflammation and cognition in older adults with and without cognitive impairment

Understanding how different inflammatory markers relate to cognition is important for the development of therapeutic targets in Alzheimer’s disease (AD). However, many studies have relied on a single, broad measure of inflammation or a select handful of markers that have been identified in the AD literature. We examined a large set of plasma inflammatory markers that were statistically grouped via principal component analysis (PCA). Associations between inflammation component scores and cognition were examined.
