West Sweden Parkinson Objective Measurement Registry Study - an Observational Cohort Study of the Prevalence and Development of Motor Symptoms Assessed With Automated Accelerometry in People With Parkinson's Disease in West Sweden

The following data will be collected at baseline:

Date of birth Handedness Family history of Parkinson's disease Time of first motor symptom onset Laterality of symptom onset Time of diagnosis Time of first pharmacological intervention (if applicable) First antiparkinsonian drug

Patient self assessments: PDQ8, NMS-Questionnaire, EQ5D-5L, Patient Reported Outcome in Parkinson's Disease (PRO-PD)

Parkinson Kinetigraph (PKG) accelerometry based recording of spontaneous movement patterns over a 6x24h period. The following indices will be extracted: median bradykinesia score (BKS), median dyskinesia score (DKS), Fluctuation Dyskinesia Score (FDS), Percent daytime with Immobility (PTI%), Percent daytime with tremor (PTT%).
