Abstract
OBJECTIVES: There will be an increase in the number of people with dementia (DEM) and Parkinson's disease (PD) with the ageing of the population. The aim of the study was to calculate prevalences and trends of prevalences for DEM and PD in Germany to enable reliable public health planning. METHODS: For the years 2009-2012, sex-specific period prevalences of DEM and PD for 5-year age-groups based on health claims data from all German statutory health insurance funds were calculated. Time trends were estimated using a negative binomial regression. RESULTS: In 2012 and for persons aged 65 or older, the crude prevalence was 7.9% for DEM and 2.2% for PD. Between 2009 and 2012, a mean decrease of the DEM prevalence by 1.2% per year was found for women and men above age 65. For PD we found constant rates between 2009-2012 among men and an annual mean decrease of PD prevalence of 0.5% among women. CONCLUSION: A reduction of the DEM prevalence by 1.2% per year could partially counterbalance the increase of people with dementia resulting from ageing population. For PD we found decreasing prevalences only among women. Thieme. All rights reserved.
