preserved baseline language and slower decline on attention. Correlations between baseline and follow-up (mean MRI-interval 1.560.8 years) factor expressions were r1⁄40.56, r1⁄40.77 and r1⁄40.91 (p<0.05), indicating that factor expressions were robust over time. Finally, there were no correlations between factor expressions, MMSE and whole-brain atrophy, suggesting that factor expressions are not predominantly reflecting clinical or biological disease progression. Conclusions: PCA patients displayed distinct and robust latent atrophy factors that were associated with specific cognitive deficits and longitudinal trajectories, mostly in line with established brain-behavior relationships. This approach highlights substantial phenotypical heterogeneity within the spectrum of PCA.
