Eleven clusters were identified on the clustering timeline (Figure 7C), including “cognitive impairment,” “nf-kappa b p65,” “nf-kappa b p65,” “mild cognitive impairment,” “postoperative cognitive dysfunction,” “natural products,” “mitochondrial dysfunction,” “gut microbiota,” “Alzheimer’s disease,” “impairment,” and “ketogenic diet.” Neuroinflammation demonstrated a high influence in NF-κB in CI. Here, NFKB1 is linked to Alzheimer disease.
