Category: Parkinson's Disease: Non-Motor Symptoms
Objective: The aim of the present study was to analyze the progression of non-motor symptoms (NMS) burden in Parkinson´s disease (PD) patients regarding the development of motor fluctuations (MF). Moreover, the change in health-related quality of life (HR-QoL) was analyzed as well.
Background: Recently, we observed in a cross-sectional study that NMS burden is strongly correlated to motor complications in patients with PD [1].
Method: PD patients without MF at baseline, who were recruited from January/2016 to November/2017 (baseline visit; V0) and evaluated again at 2-year follow-up (V2; 24 months ± 1 month) from 35 centers of Spain from the COPPADIS cohort [2], were included in this analysis. MF development at V2 was defined as a score ≥ 1 in the item-39 of the Unified Parkinson´s Disease Rating Scale – Part IV (UPDRS-IV-item/39) whereas NMS burden according to the Non-Motor Symptoms Scale (NMSS) total score. The HR-QoL was assessed with the 39-item Parkinson’s disease Questionnaire (PDQ-39).
Results: Three hundred and thirty PD patients (62.6 ± 8.7 years old; 58.8% males) were included. From V0 to V2, 27.6% of the patients developed MF. The mean NMSS total score at baseline was higher in those patients who developed MF after the 2-year follow-up (46.3 ± 36.4 vs 34.3 ± 29.1; p=0.001) (Figure 1). A greater increase in the NMSS total score from V0 to V2 was observed in those patients who developed MF (+ 16.0 ± 37.3) compared to those who didn´t develop MF (+ 6.2 ± 25.8) (p=0.021). Similar results were observed in terms of HR-QoL (Figure 2). To develop MF after a 2-year follow-up was associated with an increase in the NMSS total score (β=0.137; p=0.025) after adjustment to age, gender, levodopa equivalent daily dose, years from symptoms onset and the NMSS total score at baseline.
Conclusion: In PD patients, the development of MF is associated with a greater increase in the NMS burden and HR-QoL impairment after a 2-year follow-up.
