Short title used by the registry

Dutch Parkinson, Cognition and Driving Ability study part two (DUPARC-drive 2): A study on fitness to drive in early phase Parkinson*s Disease patients.

Original description

Primary outcome: The primary endpoint will be a cut-off score on the MoCA which has high, preferably 100% sensitivity and reasonable specificity (>70%) in predicting the failure on the CBR on-road driving assessment. Secondary outcome: The study sample will be divided into a pass and fail group, based on the on-road driving assessment. Groups will be compared in terms of age, disease severity, and performance on motor-, cognitive- and driving simulator tests. In addition, regression analyses will be used to detect predictors for failing on-road driving assessment.
