Serum tumour necrosis factor‐α and interleukin‐6 levels in Alzheimer's disease and mild cognitive impairment

Abstract

The present study suggests that serum IL-6 levels of patients with AD might be higher than those of subjects with MCI and healthy controls. Serum TNF-α and IL-6 levels might be negatively correlated with cognitive function, and we suspect that serum IL-6 levels could be biomarkers for AD.
