Predicting cognitive decline in healthy older adults

Am J Geriatr Psychiatry. 2005 Aug;13(8):735-40. doi: 10.1176/appi.ajgp.13.8.735.

Abstract

Objective: Authors performed a neuropsychological determination of which individuals in a group of community-dwelling, healthy elderly volunteers would develop cognitive decline.

Methods: A group of 155 volunteers reporting good memory and thinking participated in a prospective study over 4 years. Authors monitored cognitive functioning and incidence of Mild Cognitive Impairment (MCI)/Alzheimer disease (AD).

Results: Baseline assessment revealed a subgroup of participants with deficits in associative learning and naming; subsequent cognitive decline was more precipitous in these individuals, who also showed higher relative risk of MCI/AD.

Conclusion: Cognitive measures may be useful in community and clinical dementia screening and applicable for identifying enriched samples for trials of anti-dementia treatments.
