Moreover, IFN-γ (P = 0.335) (Figure 3J) and IL-4 (P = 0.410) (Figure 3K) levels were similar between patients with and without cognitive impairment, but IL-17A was enhanced in patients with cognitive impairment compared to those without cognitive impairment (P < 0.001) (Figure 3L). Here, IL17A is linked to Cognitive impairment.
