The role of chronic inflammation in degenerative diseases associated with aging is considered to be a primary vector for the progression of neurodegenerative disorders and a powerful factor that underlies their etiology.
One needs only to look at the leading causes of mortality—heart disease and stroke, and the research models of inflammation that clearly link the pathogenesis of these disease processes in aging individuals to understand that inflammation and chronic degenerative disease are inseparable.
Since inflammation is central to aging-associated disease processes, it has been heavily investigated in models of neurodegeneration. In Alzheimer’s disease, several studies have sought to clarify whether inflammation is a causative stimulus, or a concomitant feature of the disease process. (more…)
