The results indicated that patients with PSCI have significantly higher levels in the incidence of stroke history, the NIHSS score on admission, fibrinogen (all p < 0.05), as well as lower levels in education level, MOCA scores, lymphocytes, triglyceride, total cholesterol, low-density cholesterol, C-Reactive Protein, and SUA/SCr ratio (all p < 0.05). Here, CRP is linked to stroke disorder.
