CLINICAL AND DEMOGRAPHIC CHARACTERISTICS OF PARTICIPANTS

lvPPAHealthy controls
N1022
Age (years)66.9 (10.2)62.5 (7.4)
Education (years)16.7 (2.9)14.8 (2.3)
MMSE (max=30)20.0 (7.4)28.8 (1.2)
Digit Span (max=9)4.7 (1.9)NA
Pyramids and Palm Trees (max=50)43.3 (6.5)NA

Values listed are means with standard deviations. LvPPA and controls were matched for age (t(30)=1.37, ns). LvPPA had marginally higher education (t(30)=2.03, p=.051). As expected, lvPPA had lower MMSE scores (t(29)=5.41, p<.001) (MMSE score was not available for one control).
