Figure 1. Results from a latent profile analysis (LPA) in two independent European cohorts: the middle-aged Barcelona Brain Health Initiative (BBHI, N=741, mean age 53) and the older-adult Medit-Ageing (N=279, mean age 71) studies. The figure shows strikingly similar latent profiles in both cohorts, each identifying a three-class solution: “high levels of psychological risk factors” (Class-1), “average levels of psychological risk and protective factors” (Class-2) and “low levels of psychological protective factors” (Class-3).
