Propositional density in spoken and written language of Czech-speaking patients with mild cognitive impairment
Popis výsledku v původním jazyce
Purpose: Propositional density (PD) is a measure of content richness in language production that declines in normal aging and more profoundly in dementia. The present study had two goals: 1) test a propositional density scoring system for Czech; 2) compare propositional density in spoken and written language productions of older people with mild cognitive impairment (MCI) and control participants matched on age, gender, and education. Method: Groups of MCI patients and cognitively healthy controls (N=20 each) provided short spoken and language samples. Two samples were elicited for each modality, one describing recent events and one childhood memories. A series of neuropsychological tests were administered. The groups were compared using t-tests, the relations between measures using correlation coefficients. Results: PD was lower in spoken productions of patients with MCI, compared to controls, but only in language samples based on remote memories. PD in these samples was related to verbal fluency and education, but not working memory. PD in written samples did not differ in participants with MCI and controls. Conclusions: PD in spoken language reflects the cognitive decline in MCI, but the effect is relatively mild. The results support the existing findings that PD is related to verbal fluency.
