Abstract
OBJECTIVE: To examine the prevalence of Parkinson's disease (PD) in Bankstown, Sydney, using the same methodology as a previous study in Randwick, Sydney, Australia (1998-1999). PARTICIPANTS AND METHODS: Twenty census districts (CDs) for the Bankstown local government area were randomly selected. Research personnel door-knocked every household within the CDs to locate people aged > or =55 years. A structured questionnaire (containing four screening questions for PD) was administered to those agreeing to participate. Screened positive participants were invited to come for a clinical examination. This is a continuation of the previous study and data have been combined. RESULTS: Combining data for Bankstown and Randwick gave 1028 participants; crude prevalence, 780 per 100,000 (CI: 546-1077). In Bankstown, there were 501 participants aged > or =55 years (response rate 70%); 135 were screened positive with 101 (74.8%) agreeing to a clinical examination. The prevalence of PD in the Bankstown community was 3.4% (17 of 501) (95% CI: 1.98-5.43) for those aged > or =55 years; crude prevalence 776 per 100,000 (CI: 452-1241). CONCLUSION: The combined results of two Sydney studies appear to indicate that Sydney has one of the highest prevalence estimates of PD in developed countries. Blackwell Munksgaard 2004
