Background and purpose
The objective of this study was to analyze the relationship between motor complications and non‐motor symptom (NMS) burden in a population of patients with Parkinson’s disease ...(PD) and also in a subgroup of patients with early PD.
Methods
Patients with PD from the COPPADIS cohort were included in this cross‐sectional study. NMS burden was defined according to the Non‐Motor Symptoms Scale (NMSS) total score. Unified Parkinson’s Disease Rating Scale (UPDRS) part IV was used to establish motor complication types and their severity. Patients with ≤5 years of symptoms from onset were included as patients with early PD.
Results
Of 690 patients with PD (62.6 ± 8.9 years old, 60.1% males), 33.9% and 18.1% presented motor fluctuations and dyskinesia, respectively. The NMS total score was higher in patients with motor fluctuations (59.2 ± 43.1 vs. 38.3 ± 33.1; P < 0.0001) and dyskinesia (63.5 ± 40.7 vs. 41.4 ± 36.3; P < 0.0001). In a multiple linear regression model and after adjustment for age, sex, disease duration, Hoehn & Yahr stage, UPDRS‐III score and levodopa equivalent daily dose, UPDRS‐IV score was significantly related to a higher NMSS total score (β = 0.27; 95% confidence intervals, 2.81–5.61; P < 0.0001), as it was in a logistic regression model on dichotomous NMSS total score (≤40, mild or moderate vs. >40, severe or very severe) (odds ratio, 1.31; 95% confidence intervals, 1.17–1.47; P < 0.0001). In the subgroup of patients with early PD (n = 396; mean disease duration 2.7 ± 1.5 years), motor fluctuations were frequent (18.1%) and similar results were obtained.
Conclusions
Motor complications were frequent and were associated with a greater NMS burden in patients with PD even during the first 5 years of disease duration.
Background and Objective: Non-motor symptoms (NMS) progress in different ways between Parkinson’s disease (PD) patients. The aim of the present study was to (1) analyze the change in global NMS ...burden in a PD cohort after a 2-year follow-up, (2) to compare the changes with a control group, and (3) to identify predictors of global NMS burden progression in the PD group. Material and Methods: PD patients and controls, recruited from 35 centers of Spain from the COPPADIS cohort from January 2016 to November 2017, were followed-up with after 2 years. The Non-Motor Symptoms Scale (NMSS) was administered at baseline (V0) and at 24 months ± 1 month (V2). Linear regression models were used for determining predictive factors of global NMS burden progression (NMSS total score change from V0 to V2 as dependent variable). Results: After the 2-year follow-up, the mean NMS burden (NMSS total score) significantly increased in PD patients by 18.8% (from 45.08 ± 37.62 to 53.55 ± 42.28; p < 0.0001; N = 501; 60.2% males, mean age 62.59 ± 8.91) compared to no change observed in controls (from 14.74 ± 18.72 to 14.65 ± 21.82; p = 0.428; N = 122; 49.5% males, mean age 60.99 ± 8.32) (p < 0.0001). NMSS total score at baseline (β = −0.52), change from V0 to V2 in PDSS (Parkinson’s Disease Sleep Scale) (β = −0.34), and change from V0 to V2 in NPI (Neuropsychiatric Inventory) (β = 0.25) provided the highest contributions to the model (adjusted R-squared 0.41; Durbin-Watson test = 1.865). Conclusions: Global NMS burden demonstrates short-term progression in PD patients but not in controls and identifies worsening sleep problems and neuropsychiatric symptoms as significant independent predictors of this NMS progression.
Background and objective
Recently, we demonstrated that staging Parkinson's disease (PD) with a novel simple classification called MNCD, based on four axes (motor, non‐motor, cognition, and ...dependency) and five stages, correlated with disease severity and patients’ quality of life. Here, we analyzed the correlation of MNCD staging with PD caregiver's status.
Patients and methods
Data from the baseline visit of PD patients and their principal caregiver recruited from 35 centers in Spain from the COPPADIS cohort from January 2016 to November 2017 were used to apply the MNCD total score (from 0 to 12) and MNCD stages (from 1 to 5) in this cross‐sectional analysis. Caregivers completed the Zarit Caregiver Burden Inventory (ZCBI), Caregiver Strain Index (CSI), Beck Depression Inventory‐II (BDI‐II), PQ‐10, and EUROHIS‐QOL 8‐item index (EUROHIS‐QOL8).
Results
Two hundred and twenty‐four PD patients (63 ± 9.6 years old; 61.2% males) and their caregivers (58.5 ± 12.1 years old; 67.9% females) were included. The frequency of MNCD stages was 1, 7.6%; 2, 58.9%; 3, 31.3%; and 4–5, 2.2%. A more advanced MNCD stage was associated with a higher score on the ZCBI (p < .0001) and CSI (p < .0001), and a lower score on the PQ‐10 (p = .001), but no significant differences were observed in the BDI‐II (p = .310) and EUROHIS‐QOL8 (p = .133). Moderate correlations were observed between the MNCD total score and the ZCBI (r = .496; p < .0001), CSI (r = .433; p < .0001), and BDI‐II (r = .306; p < .0001) in caregivers.
Conclusion
Staging PD according to the MNCD classification is correlated with caregivers’ strain and burden.
Recently, it has been reported that staging Parkinson's disease (PD) with a novel simple classification called MNCD, based on 4 axes (Motor; Non‐motor; Cognition; Dependency) and 5 stages, correlated with disease severity and patients' quality of life. In this new manuscript, we observed that staging PD according to the MNCD classification correlated with caregivers' strain and burden.
There is a need for identifying risk factors for hospitalization in Parkinson's disease (PD) and also interventions to reduce acute hospital admission.
To analyze the frequency, causes, and ...predictors of acute hospitalization (AH) in PD patients from a Spanish cohort.
PD patients recruited from 35 centers of Spain from the COPPADIS-2015 (COhort of Patients with PArkinson's DIsease in Spain, 2015) cohort from January 2016 to November 2017, were included in the study. In order to identify predictors of AH, Kaplan-Meier estimates of factors considered as potential predictors were obtained and Cox regression performed on time to hospital encounter 1-year after the baseline visit.
Thirty-five out of 605 (5.8%) PD patients (62.5±8.9 years old; 59.8% males) presented an AH during the 1-year follow-up after the baseline visit. Traumatic falls represented the most frequent cause of admission, being 23.7% of all acute hospitalizations. To suffer from motor fluctuations (HR hazard ratio 2.461; 95% CI, 1.065-5.678; p = 0.035), a very severe non-motor symptoms burden (HR hazard ratio 2.828; 95% CI, 1.319-6.063; p = 0.008), falls (HR 3.966; 95% CI 1.757-8.470; p = 0.001), and dysphagia (HR 2.356; 95% CI 1.124-4.941; p = 0.023) was associated with AH after adjustment to age, gender, disease duration, levodopa equivalent daily dose, total number of non-antiparkinsonian drugs, and UPDRS-IIIOFF. Of the previous variables, only falls (HR 2.998; 95% CI 1.080-8.322; p = 0.035) was an independent predictor of AH.
Falls is an independent predictor of AH in PD patients.

Constipation has been linked to cognitive impairment development in Parkinson's disease (PD).
Our aim was to analyze cognitive changes observed in PD patients and controls from a Spanish cohort with ...regards to the presence or not of constipation.
PD patients and controls recruited from 35 centers of Spain from the COPPADIS cohort from January 2016 to November 2017 were followed-up during 2 years. The change in cognitive status from baseline (V0) to 2-year follow-up was assessed with the PD-CRS (Parkinson's Disease Cognitive Rating Scale). Subjects with a score ≥1 on item 21 of the NMSS (Non-Motor Symptoms Scale) at baseline (V0) were considered as "with constipation". Regression analyses were applied for determining the contribution of constipation in cognitive changes.
At V0, 39.7% (198/499) of PD patients presented constipation compared to 11.4% of controls (14/123) (p < 0.0001). No change was observed in cognitive status (PD-CRS total score) neither in controls without constipation (from 100.24±13.72 to 100.27±13.68; p = 0.971) and with constipation (from 94.71±10.96 to 93.93±13.03; p = 0.615). The PD-CRS total score decreased significantly in PD patients with constipation (from 89.14±15.36 to 85.97±18.09; p < 0.0001; Coehn's effect = -0.35) compared to patients without constipation (from 93.92±15.58 to 93.14±17.52; p = 0.250) (p = 0.018). In PD patients, to suffer from constipation at V0 was associated with a decrease in the PD-CRS total score from V0 to V2 (β= -0.1; 95% CI, -4.36 - -0.27; p = 0.026) and having cognitive impairment at V2 (OR = 1.79; 95% CI, 1.01 - 3.17; p = 0.045).
Constipation is associated with cognitive decline in PD patients but not in controls.
Introduction. Drooling in Parkinson’s disease (PD) is frequent but often goes underrecognized. Our aim was to examine the prevalence of drooling in a PD cohort and compare it with a control group. ...Specifically, we identified factors associated with drooling and conducted subanalyses in a subgroup of very early PD patients. Patients and Methods. PD patients who were recruited from January 2016 to November 2017 (baseline visit; V0) and evaluated again at a 2-year ± 30-day follow-up (V2) from 35 centers in Spain from the COPPADIS cohort were included in this longitudinal prospective study. Subjects were classified as with or without drooling according to item 19 of the NMSS (Nonmotor Symptoms Scale) at V0, V1 (1-year ± 15 days), and V2 for patients and at V0 and V2 for controls. Results. The frequency of drooling in PD patients was 40.1% (277/691) at V0 (2.4% (5/201) in controls; p < 0.0001), 43.7% (264/604) at V1, and 48.2% (242/502) at V2 (3.2% (4/124) in controls; p < 0.0001), with a period prevalence of 63.6% (306/481). Being older (OR = 1.032; p = 0.012), being male (OR = 2.333; p < 0.0001), having greater nonmotor symptom (NMS) burden at the baseline (NMSS total score at V0; OR = 1.020; p < 0.0001), and having a greater increase in the NMS burden from V0 to V2 (change in the NMSS total score from V0 to V2; OR = 1.012; p < 0.0001) were identified as independent predictors of drooling after the 2-year follow-up. Similar results were observed in the group of patients with ≤2 years since symptom onset, with a cumulative prevalence of 64.6% and a higher score on the UPDRS-III at V0 (OR = 1.121; p = 0.007) as a predictor of drooling at V2. Conclusion. Drooling is frequent in PD patients even at the initial onset of the disease and is associated with a greater motor severity and NMS burden.
Sex plays a role in Parkinson's disease (PD) mechanisms. We analyzed sex difference manifestations among Spanish patients with PD.
PD patients who were recruited from the Spanish cohort COPPADIS from ...January 2016 to November 2017 were included. A cross-sectional and a two-year follow-up analysis were conducted. Univariate analyses and general linear model repeated measure were used.
At baseline, data from 681 PD patients (mean age 62.54 ± 8.93) fit the criteria for analysis. Of them, 410 (60.2%) were males and 271 (39.8%) females. There were no differences between the groups in mean age (62.36 ± 8.73 vs. 62.8 ± 9.24;
= 0.297) or in the time from symptoms onset (5.66 ± 4.65 vs. 5.21 ± 4.11;
= 0.259). Symptoms such as depression (
< 0.0001), fatigue (
< 0.0001), and pain (
< 0.00001) were more frequent and/or severe in females, whereas other symptoms such as hypomimia (
< 0.0001), speech problems (
< 0.0001), rigidity (
< 0.0001), and hypersexuality (
< 0.0001) were more noted in males. Women received a lower levodopa equivalent daily dose (
= 0.002). Perception of quality of life was generally worse in females (PDQ-39,
= 0.002; EUROHIS-QOL8,
= 0.009). After the two-year follow-up, the NMS burden (Non-Motor Symptoms Scale total score) increased more significantly in males (
= 0.012) but the functional capacity (Schwab and England Activities of Daily Living Scale) was more impaired in females (
= 0.001).
The present study demonstrates that there are important sex differences in PD. Long-term prospective comparative studies are needed.
Background
The Movement Disorder Society‐sponsored Non‐motor Rating Scale (MDS‐NMS) assess the severity and disability caused by non‐motor symptoms (NMS) in Parkinson's disease (PD).
Objective
This ...article encapsulates the formal process for completing this program and the data on the first officially approved non‐English version of the MDS‐NMS (Spanish).
Methods
The MDS‐NMS translation program involves four steps: translation and back‐translation; cognitive pre‐testing to ensure that raters and patients understand the scale and are comfortable with its content; field testing of the finalized version; analysis of the factor structure of the tested version against the original English language version for the nine domains that could be analyzed in a confirmatory factor analysis. To be designated an “Official MDS translation,” the confirmatory factor analysis Comparative Fit Index had to be ≥0.90.
Results
The Spanish MDS‐NMS was tested in 364 native‐Spanish‐speaking patients with PD from seven countries. For all subjects with fully computable data with all domains of the MDS‐NMS (n = 349), the Comparative Fit Index was ≥0.90 for the nine eligible domains. Missing data were negligible and moderate floor effect (42.90%) was found for the Non‐Motor Fluctuations subscale. Item homogeneity coefficient was adequate, and the correlation of the MDS‐NMS domains with other measures for related constructs was acceptable (rs ≥ 0.50).
Conclusions
The Spanish version of the MDS‐NMS followed the IPMDS Translation Program protocol, reached the criterion to be designated as an Official Translation, and is now available on the MDS website.
