Long-Term Cognitive Decline in Dementia with Lewy Bodies in a Large Multicenter, International Cohort.

ABSTRACT:

Background/objective

The aim of this study was to describe the rate and clinical predictors of cognitive decline in dementia with Lewy bodies (DLB), and compare the findings with Alzheimer's disease (AD) and Parkinson's disease dementia (PDD) patients.

Methods

Longitudinal scores for the Mini-Mental State Examination (MMSE) in 1,290 patients (835 DLB, 198 PDD, and 257 AD) were available from 18 centers with up to three years longitudinal data. Linear mixed effects analyses with appropriate covariates were used to model MMSE decline over time. Several subgroup analyses were performed, defined by anti-dementia medication use, baseline MMSE score, and DLB core features.

Results

The mean annual decline in MMSE score was 2.1 points in DLB, compared to 1.6 in AD (p = 0.07 c
