Abstract

The association between inflammation and neuropsychiatric symptoms in old age is generally accepted but poorly understood. The purpose of this study was to examine whether inflammation precedes depressive symptoms and cognitive decline in old age, and to identify specific inflammatory pathways herein. We measured serum C-reactive protein (CRP) and lipopolysaccharide-induced production of Interleukin (IL)-1beta, IL-6, Tumor Necrosis Factor (TNF)-alpha, IL-1 receptor antagonist (ra), and IL-10 levels in 85-year-old participants free from neuropsychiatric symptoms at baseline (n=267). Participants were prospectively followed for depressive symptoms (Geriatric Depression Scale) and cognitive functioning (Mini Mental State Examination) from 85 to 90 years. Higher baseline CRP levels preceded accelerated increase in depressive symptoms (p<0.001). A higher production capacity of the pro-inflammatory cytokine IL-1beta preceded a greater increase of depressive symptoms (p=0.06), whereas that of its natural antagonist IL-1ra preceded a smaller increase of depressive symptoms (p=0.003). There was no relation of CRP, IL-1beta, and IL-1ra with cognitive decline. Our findings show that in old age inflammatory processes contribute to the development of depressive symptoms but not cognitive decline. A high innate IL-1ra to IL-1beta production capacity reflects a better ability to neutralize inflammation and may therefore protect against depressive symptoms.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
