Balanced FTLDc PPA score results within 1 year. Balanced FTLDc-PPA sum scores at baseline (v1) and at follow-up of 1 year (v2). Boxes show the 25–75% percentile range with median, and whiskers indicate minimum and maximum. *Significant changes within 1 year, calculated via paired t tests are indicated by brackets (healthy controls (HC): p = 0.780; nonfluent variant primary progressive aphasia (nfvPPA): p = 0.002; semantic variant primary progressive aphasia (svPPA): p = 0.016; logopenic variant primary progressive aphasia (lvPPA): p = 0.001)
