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).
PD patients ...without MF at baseline, who were recruited from January 2016 to November 2017 (V0) and evaluated again at a 2-year follow-up (V2) from 35 centers of Spain from the COPPADIS cohort, were included in this analysis. MF development at V2 was defined as a score ≥ 1 in the item-39 of the UPDRS-Part IV, whereas NMS burden was defined according to the Non-motor Symptoms Scale (NMSS) total score.
Three hundred and thirty PD patients (62.67 ± 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 (46.34 ± 36.48 vs. 34.3 ± 29.07;
= 0.001). A greater increase in the NMSS total score from V0 to V2 was observed in patients who developed MF (+16.07 ± 37.37) compared to those who did not develop MF (+6.2 ± 25.8) (
= 0.021). Development of MF after a 2-year follow-up was associated with an increase in the NMSS total score (β = 0.128;
= 0.046) after adjustment to age, gender, years from symptoms onset, levodopa equivalent daily dose (LEDD) and the NMSS total score at baseline, and the change in LEDD from V0 to V2.
In PD patients, the development of MF is associated with a greater increase in the NMS burden after a 2-year follow-up.
Abstract Objective Several studies suggest that transcutaneous electrical stimulation (TENS) can have a variety of effects on the central nervous system (CNS). In this study, we tried to replicate ...the physiological effects of TENS and to explore its effects on intracortical circuits. Methods We used transcranial magnetic stimulation (TMS) and spinal reflex testing to examine excitability of intracortical and spinal cord circuits before and after a 30-min period of TENS over the flexor carpi radialis (FCR) muscle. We measured the amplitude of TMS-evoked muscle responses (MEP), short interval intracortical inhibition (SICI), intracortical facilitation (ICF) and cortical antagonist inhibition (CAI) in flexor and extensor carpial radialis (FCR, ECR) muscles as well as spinal reciprocal inhibition (RI) and presynaptic inhibition (PI) from ECR to FCR. Results TENS had no significant effect on any of these measures apart from a reduction in median nerve induced facilitation of FCR when testing CAI. Conclusions When compared with previous studies, our results suggest that the effects of TENS are highly variable and unreliable, likely by the difficulty in defining precise parameters of stimulation in individual subjects. Significance Care should be taken in assuming that effects after TENS observed in small populations of subjects will apply equally to a wider population.
Background and objective
Patients with young-onset Parkinson’s disease (YOPD) have a slower progression. Our aim was to analyze the change in cognitive function in YOPD compared to patients with a ...later onset and controls.
Patients and methods
Patients with Parkinson’s disease (PD) and controls from the COPPADIS cohort were included. Cognitive function was assessed with the Parkinson’s Disease Cognitive Rating Scale (PD-CRS) at baseline (V0), 2-year ± 1 month (V2y), and 4-year ± 3 months follow-up (V4y). Regarding age from symptoms onset, patients were classified as YOPD (< 50 years) or non-YOPD (≥ 50). A score in the PD-CRS < 81 was defined as cognitive impairment (CI): ≤ 64 dementia; 65–80 mild cognitive impairment (MCI).
Results
One-hundred and twenty-four YOPD (50.7 ± 7.9 years; 66.1% males), 234 non-YOPD (67.8 ± 7.8 years; 59.3% males) patients, and 205 controls (61 ± 8.3 years; 49.5% males) were included. The score on the PD-CRS and its subscore domains was higher at all visits in YOPD compared to non-YOPD patients and to controls (
p
< 0.0001 in all analysis), but no differences were detected between YOPD patients and controls. Only non-YOPD patients had significant impairment in their cognitive function from V0 to V4y (
p
< 0.0001). At V4y, the frequency of dementia and MCI was 5% and 10% in YOPD compared to 25.2% and 22.3% in non-YOPD patients (
p
< 0.0001). A lower score on the Parkinson’s Disease Sleep Scale at baseline was a predictor of CI at V4y in YOPD patients (Adjusted
R
2
= 0.61; OR = 0.965;
p
= 0.029).
Conclusion
Cognitive dysfunction progressed more slowly in YOPD than in non-YOPD patients.
ABSTRACT
Background
Levodopa‐induced dyskinesias (LID) are frequent in Parkinson's disease (PD).
Objective
To analyze the change in the frequency of LID over time, identify LID related factors, and ...characterize how LID impact on patients’ quality of life (QoL).
Patients and Methods
PD patients from the 5‐year follow‐up COPPADIS cohort were included. LID were defined as a non‐zero score in the item “Time spent with dyskinesia” of the Unified Parkinson's Disease Rating Scale—part IV (UPDRS‐IV). The UPDRS‐IV was applied at baseline (V0) and annually for 5 years. The 39‐item Parkinson's disease Questionnaire Summary Index (PQ‐39SI) was used to asses QoL.
Results
The frequency of LID at V0 in 672 PD patients (62.4 ± 8.9 years old; 60.1% males) with a mean disease duration of 5.5 ± 4.3 years was 18.9% (127/672) and increased progressively to 42.6% (185/434) at 5‐year follow‐up (V5). The frequency of disabling LID, painful LID, and morning dystonia increased from 6.9%, 3.3%, and 10.6% at V0 to 17.3%, 5.5%, and 24% at V5, respectively. Significant independent factors associated with LID (P < 0.05) were a longer disease duration and time under levodopa treatment, a higher dose of levodopa, a lower weight and dose of dopamine agonist, pain severity and the presence of motor fluctuations. LID at V0 (β = 0.073; P = 0.027; R2 = 0.62) and to develop disabling LID at V5 (β = 0.088; P = 0.009; R2 = 0.73) were independently associated with a higher score on the PDQ‐39SI.
Conclusion
LID are frequent in PD patients. A higher dose of levodopa and lower weight were factors associated to LID. LID significantly impact QoL.
