Background and Objective Caregiver burden in Parkinson's disease (PD) has been studied in many cross‐sectional studies but poorly in longitudinal ones. The aim of the present study was to analyze the change in burden, strain, mood, and quality of life (QoL) after a 2‐year follow‐up in a cohort of caregivers of patients with PD and also to identify predictors of these changes. Patients and Methods PD patients and their caregivers who were recruited from January/2016 to November/2017 from 35 centers of Spain from the COPPADIS cohort were included in the study. They were evaluated again at 2‐year follow‐up. Caregivers completed the Zarit Caregiver Burden Inventory (ZCBI), Caregiver Strain Index (CSI), Beck Depression Inventory‐II (BDI‐II), and EUROHIS‐QOL 8‐item index (EUROHIS‐QOL8) at baseline (V0) and at 2‐year follow‐up (V2). General linear model repeated measure and lineal regression models were applied. Results Significant changes, indicating an impairment, were detected on the total score of the ZCBI (p < 0.0001), CSI (p < 0.0001), BDI‐II (p = 0.024), and EUROHIS‐QOL8 (p = 0.002) in 192 PD caregivers (58.82 ± 11.71 years old; 69.3% were females). Mood impairment (BDI‐II; β = 0.652; p < 0.0001) in patients from V0 to V2 was the strongest factor associated with caregiver's mood impairment after the 2‐year follow‐up. Caregiver's mood impairment was the strongest factor associated with an increase from V0 to V2 on the total score of the ZCBI (β = 0.416; p < 0.0001), CSI (β = 0.277; p = 0.001), and EUROHIS‐QOL (β = 0.397; p = 0.002). Conclusion Burden, strain, mood, and QoL were impaired in caregivers of PD patients after a 2‐year follow‐up. Mood changes in both the patient and the caregiver are key aspects related to caregiver burden increase.

Introduction: The aim of the present study was to examine the frequency of self-reported sleep problems and their associated factors in a large cohort of PD patients. Methods: PD patients and controls, recruited from 35 centers of Spain from the COPPADIS cohort were included in this cross-sectional study. Sleep problems were assessed by the Spanish version of the Parkinson’s disease Sleep Scale version 1 (PDSS-1). An overall score below 82 or a score below 5 on at least 1 item was defined as sleep problems. Results: The frequency of sleep problems was nearly double in PD patients compared to controls: 65.8% (448/681) vs 33.5% (65/206) (p < 0.0001). Mean total PDSS score was lower in PD patients than controls: 114.9 ± 28.8 vs 132.8 ± 16.3 (p < 0.0001). Quality of life (QoL) was worse in PD patients with sleep problems compared to those without: PDQ-39SI, 19.3 ± 14 vs 13 ± 11.6 (p < 0.0001); EUROHIS-QoL8, 3.7 ± 0.5 vs 3.9 ± 0.5 (p < 0.0001). Non-motor symptoms burden (NMSS; OR = 1.029; 95%CI 1.015–1.043; p < 0.0001) and impulse control behaviors (QUIP-RS; OR = 1.054; 95%CI 1.009–1.101; p = 0.018) were associated with sleep problems after adjustment for age, gender, disease duration, daily equivalent levodopa dose, H&Y, UPDRS-III, UPDRS-IV, PD-CRS, BDI-II, NPI, VAS-Pain, VAFS, FOGQ, and total number of non-antiparkinsonian treatments. Conclusion: Sleep problems were frequent in PD patients and were related to both a worse QoL and a greater non-motor symptoms burden in PD. These findings call for increased awareness of sleep problems in PD patients.

Background: Detection of suicidal ideation (SI) is key for trying to prevent suicide.The aim of this study was to analyze the frequency of SI and related factors in Spanish people with Parkinson's Disease (PwPD) and to compare them with a control group.Methods: PD patients and controls recruited from the Spanish cohort COPPADIS from January 2016 to November 2017 were included. Two visits were conducted: V0 (baseline); V2 (2-year � 1 month follow-up). SI was defined as a score ≥1 on item nine of the Beck Depression Inventory-II (BDI-II). Regression analyses were conducted to identify factors related to SI.
