Patients with lvPPA produced fewer verbs (10.5 ± 2.3; p = 0.001) and adjectives (2.7 ± 1.3, p = 0.019) and more fillers (7.4 ± 3.9; p = 0.022) with lower lexical diversity (0.84 ± 0.1; p = 0.05) and higher pause rate (54.2 ± 19.2; p = 0.015) than individuals with aAD (verbs 12.5 ± 2; adjectives 3.8 ± 2; fillers 4.9 ± 4.5; lexical diversity 0.87 ± 0.1; pause rate 45.3 ± 12.8). Both groups showed some shared language impairments compared with HC. Word frequency (MMSE score: β = −1.6, p = 0.009; Boston Naming Test [BNT] score: β = −4.36, p < 0.001), adverbs (MMSE score: β = −1.9, p = 0.003; BNT score: β = −2.41, p = 0.041), pause rate (MMSE score: β = −1.21, p = 0.041; BNT score: β = −2.09, p = 0.041), and word length (MMSE score: β = 1.75, p = 0.001; BNT score: β = 2.94, p = 0.003) were significantly correlated with both MMSE and BNT scores, but other measures were not correlated with MMSE and/or BNT score. Prepositions (r = −0.36, p = 0.019), nouns (r = −0.31, p = 0.047), speech segment duration (r = −0.33, p = 0.032), word frequency (r = 0.33, p = 0.036), and pause rate (r = 0.34, p = 0.026) were correlated with patients' CSF p-tau levels.Discussion Our measures captured language and speech differences between the 2 phenotypes that traditional language-based clinical assessments failed to identify. This work demonstrates the potential of natural speech in reflecting underlying variants with AD pathology.aAD=amnestic AD; Aβ=β-amyloid42; AD=Alzheimer disease; BNT=Boston Naming Test; lvPPA=logopenic variant PPA; p-tau=phosphorylated tau; POS=part-of-speech; PPA=primary progressive aphasia ER -
