SAND, screening for Aphasia in NeuroDegeneration battery; AAT, Aachener Aphasie test; IC, independent component(sources) from SBM analysis; SBM, source-based morphometry; uncorrected (for multiple comparisons) p is reported for each comparison; corrected p (for multiple comparisons) is reported between squared brackets; when significant (p < 0.05), Pearson's correlation (r) value was reported between round brackets. Statistical comparisons surviving multiple comparisons corrections (p < 0.05 Holm-Bonferroni) were highlighted in light gray.
