Curation Notations:

  1. PD medication names were aligned with the provided by CDH list of relevant pd medications and pd medication class.
  2. For PD medication start date (yyyy-mm) the earliest date from the list of pd medication names was used. Fields “CMINDC” (Indication), “DISMED” (PD Medication?), “CMTRT” (Med Name) in PPMI and BioFIND Concomitant_Medications.csv and Concomitant_Medication_Log.csv were used to extract pd medication name, clean and further align it with the list of relevant pd medications to determine STARTDT (start date).
