Present findings further contribute to the growing evidence that supports the role of the pro-inflammatory cytokine IL-6 in the occurrence of cognitive impairment post-chemotherapy.
Our results suggest that elevated IL-6 levels may play the role in cognitive impairment and serve as potential inflammatory biomarker of deterioration in schizophrenia.
IL-6 174 G > C information were compared among these groups.Results We observed that individuals with cognitive impairment no dementia with GGlowergenotype were more frequent among global cognitive score non-decliners while carriers of at least one Chigherallele were more frequent in the group with global cognitive score decliners (p = 0.012; RR = 3.095 IC95%= 1.087-8.812).Conclusion These results suggest that the higher expression of IL-6 gene may be an independent risk factor for cognitive decline among individuals with cognitive impairment no dementia.
In the prospective analysis, higher IL-6 concentration was associated with an increased rate of cognitive decline in both executive function (P = 0.002) and memory function (P = 0.002), again independent of cardiovascular disease status and risk factors.
Taken together, these findings indicate that IL-6, while not useful alone, has potential in combination with other biomarkers to support early diagnosis of aMCI due to its association with the progression of cognitive impairment.
The purpose of the study was to test the hypothesis that single nucleotide polymorphisms (SNPs) within interleukin (IL)-18, TNF-alpha, IL-6 and IL-10 gene promoter regions are risk factors for cognitive decline in healthy octogenarians, and to isolate the strongest inflammatory biomarkers of cognitive function in the peripheral blood.
To assess whether serum levels of the inflammatory proteins alpha(1)-antichymotrypsin (ACT), C-reactive protein (CRP), interleukin-6 (IL-6), and albumin are associated with cognitive decline in older persons.
Interleukin-6 (IL-6), an inflammatory cytokine, is thought to play a role in neurodegeneration of the central nervous system and has been associated with increased amyloid precursor protein expression in vitro and greater cognitive decline.
The aim of this study is to stress on age-related neuropsychological and electrophysiological (P(300)) changes in normal Egyptian subjects, to throw light on the value of genetic (Apo-E(4) genotype) and immunological markers [interleukin-6 (IL-6) and intercellular adhesion molecules (ICAM-1) in the serum] as tools used in early detection of cognitive decline in cerebral aging.
