Oral language in Alzheimer's disease (AD) participants and healthy older controls was analyzed using propositional analysis. The idea density was evaluated for its usefulness in discriminating between healthy elderly subjects and AD patients. Results suggest that scores of idea density accounts for a marker of pathological cognitive decline. This linguistic cue can be regarded as a reliable measure for future medical screening.
