Longitudinal Associations between Survival in Alzheimer's Disease and Cholinesterase Inhibitor Use, Progression, and Community-Based Services.

Research output: Contribution to journalArticle


Background/Aims: Factors including rate of disease progression, different aspects of cholinesterase inhibitor (ChEI) treatment, and use of community-based services might affect the longitudinal outcome of Alzheimer’s disease (AD). Whether these factors alter life expectancy in AD is unclear. We therefore examined the association between long-term ChEI therapy and survival.
Methods: The present study included 1,021 patients with a clinical diagnosis of AD and a Mini-Mental State Examination score of 10–26 at baseline from a 3-year, prospective, multicenter study of ChEI therapy in clinical practice. The relationship of potential predictors with mortality was analyzed using Cox regression models.
Results: After up to 16 years of follow-up, 841 (82%) of the participants had died. In the Alzheimer’s Disease Assessment Scale-cognitive subscale, a mean decline of >= 4 points/year or >= 2 points/year on the Physical Self-Maintenance Scale was a risk factor for an earlier death. In the multivariate models, longer survival was associated with higher ChEI dose and longer duration of treatment. Users of community-based services at baseline exhibited a 1 year shorter mean life expectancy than nonusers.
Conclusion: A longer survival time can be anticipated for AD patients with slower deterioration, who receive and tolerate higher ChEI doses and a longer duration of treatment.
