DOCK3 and Alzheimer disease: Similarly, serum NAb-α-Syn levels were significantly correlated with MoCA in the overall group (γ = 0.260, p < 0.001) and the PDD subgroup (γ = 0.300, p = 0.019), but not in the NC (γ = −0.027, p = 0.852), AD (γ = 0.013, p = 0.929), or VaD group (γ = 0.157, p = 0.273; Figure 3).
