Linguistic Features from Paragraph Recall are Markers of Cognitive Impairment.

ABSTRACT:

Objective

Cognitive impairment is associated with language changes that may be elicited from verbal responses during neuropsychological assessments that are not captured in traditional scoring. The current study investigated the utility of a linguistic analysis of paragraph recall responses for differentiating participants with and without cognitive impairment.

Methods

Digital voice recordings of Logical Memory (LM) were available from 598 participants from the Long Life Family Study with normal cognition and 112 with cognitive impairment.

Logistic regression models assessed the predictive value of each PFS and de
