The Queensland Parkinson’s Project: An Overview of 20 Years of Mortality from Parkinson’s Disease
Objective The consensus is that life expectancy for individuals with Parkinson’s disease (PD) is reduced, but estimations vary. We aimed to provide an overview of 20 years of mortality and risk factor data from the Queensland Parkinson’s Project. Methods The analysis included 1,334 PD and 1,127 cont...

We aimed to provide an overview of 20 years of mortality and risk factor data from the Queensland Parkinson’s Project. Methods The analysis included 1,334 PD and 1,127 control participants.

Cox proportional hazards regression modeling was used to analyze potential predictors of mortality. Results In total, 625 (46.8%) PD and 237 (21.0%) control participants were deceased. Mean disease duration until death was 15.3 ± 7.84 years. Average ages at death were 78.0 ± 7.4 years and 80.4 ± 8.4 years for the deceased PD and control participants, respectively. Mortality was significantly increased for PD in general {SMR = 2.75 [95% confidence interval (CI): 2.53–2.96]; p = 0.001}. SMRs were slightly higher for women and those with an age of onset before 60 years. Multivariate analysis showed that deep brain stimulation (DBS) treatment was associated with lower mortality [hazard ratio (HR) = 0.76; 95% CI: 0.59–0.98], while occasional pesticide exposure increased mortality risk (HR = 1.48; 95% CI: 1.17–1.88). Family history of PD, smoking and depression were not independent predictors of mortality. Conclusion Mortality in PD is increased. Sex, age at onset and occasional pesticide exposure were independent determinants of increased mortality, while DBS treatment was associated with reduced mortality.http://www.e-jmd.org/upload/jmd-20034.pdfdeep brain stimulationlife expectancymortalityparkinson’s diseaseprognostication |
