Within the LP group, Thal amyloid-β phases were related to presence of dementia (Spearman’s rho = 0.22, p = 0.007), CERAD neuritic plaque score (rho = 0.71, p < 0.001), Braak NFT stage (rho = 0.29, p < 0.001), Braak α-synuclein stage (rho = 0.18, p = 0.037), and presence of neocortical LP (rho = 0.33, p < 0.001). The gene discussed is PPIB; the disease is dementia.
