IL25 and Alzheimer disease: In contrast, the AD group showed that the higher baseline levels of IFNγ (r = −0.701, p = 0.036), IL-5 (r = −0.756, p = 0.019), IL-17A (r = −0.759, p = 0.021), IL-25 (r = −0.840, p = 0.036), and FGF (r = −0.780, p = 0.013) were significantly correlated with more rapid cognitive decline.
