IL-6 was not significantly associated with any of the geriatric assessment scales (Tinetti gait index: r = 0.18; p = 0.12; Tinetti balance index: r = 0.22; p = 0.064, Spearman); Barthel index to measure the activities of daily living and mobility (r = 0.91; p = 0.44, Spearman); MMSE test for cognitive impairment (r = −0.15; p = 0.20); Yesavage scale for geriatric depression (r = −0.23; p = 0.08, Spearman); or the Athens insomnia scale for severity of insomnia (r = 0.17; p = 0.14, Spearman). This evidence concerns the gene IL6 and Cognitive impairment.
