Identifying individuals at-risk of developing Parkinson's disease using a population-based recruitment strategy: The Healthy Brain Ageing Kassel Study.

ABSTRACT: Neurodegeneration in Parkinson's disease (PD) occurs before motor features develop: assessing risk factors and identifying prodromal markers is necessary to recruit prodromal cohorts, improve early diagnosis, and develop preventive therapies. As part of Healthy Brain Ageing (HeBA), we implemented a stepwise, population-based screening to identify people at high risk of developing PD. Residents (n = 158,818; 50-80 years) in and around Kassel, Germany were invited to complete an online survey with questions for prodromal symptoms and risk factors. An individual risk score was calculated (International Parkinson and Movement Disorder Society criteria). Selected individuals received a smell test. 8001 of 8774 survey responses were valid; the response rate to the smell test mailings (n = 3021)
