Relative survival in patients with dementia with Lewy bodies and Parkinson's disease dementia.

ABSTRACT:

Introduction

The understanding of survival in dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD) is limited, as well as the impact of these diagnoses in an ageing co-morbid population.

Methods

A retrospective study of 177 patients who received a DLB or PDD diagnosis between 1997-2014 at the Memory Clinic in Malmö, Sweden. Relative survival was evaluated by adjusting all-cause survival for expected survival, estimated from population life-tables, matched by sex, age and calendar year. Predictors of relative survival were investigated using multivariate regression modelling.

Results

At follow-up, 143 (81%) patients were deceased with a median survival of 4.1 years (IQR 2.6-6.0). After 10-years follow-up, the standardized mortality ratio was 3.44 (95%
