Figure 4 Linguistic ability in early life in 2 groups of subjects with an autopsy-confirmed diagnosis 5 decades later

(A) Subjects with intact cognition at death (controls and asymptomatic Alzheimer disease [ASYMAD]) compared with subjects with cognitive deficits (mild cognitive impairment [MCI] and Alzheimer disease) showed a higher idea density mean score. (B) By contrast, a significant difference between the 2 samples was not observed for the grammatic complexity mean score.
