6. Data collection and evaluation
In the framework of the evaluation of the relationship between Parkinsonian syndrome and drug exposure, one additional CRF page will be completed for the potential cases and one additional CRF page for the selected controls at the following clinical visit or at the latest at the 5 year follow up visit.
Will be considered cases the patients for which one of the following two questions has been answered “yes” and data were entered in the database at the latest on July 31, 2014:
- Has the patient an extra-pyramidal syndrome, either of Parkinsonian type (rest tremor, slowness of movements, rigidity) or abnormal involuntary movements (dyskinesia)? and
- Is the patient receiving any anti-Parkinsonian drug?
Cases and controls will be matched using the following criteria: center/ city / country, gender, year of birth, speciality of the participating physician, index date of event.
