Background
Pain is a frequent feature in Parkinson's disease (PD). Current knowledge on pain and its associated factors in PD has been obtained using nondisease‐specific tools. Recently, the King's ...Parkinson's Disease Pain Scale (KPPS) was published as the first disease‐specific scale. The aim of this study was to assess PD‐associated pain and its main determinants using the KPPS.
Methods
A cross‐sectional study was carried out. Consecutive patients with PD were recruited from a movement disorders clinic. Clinical and demographical data were collected. The KPPS, the Movement Disorders Society Unified Parkinson's Disease Rating Scale, and the Non‐Motor Symptoms Scale were used to assess all participants.
Results
In total, 314 patients were included. Overall, 88.6% of the sample reported at least 1 type of pain. The mean ± standard KPPS score was 18.8 ± 19.5. Factors associated with higher KPSS scores were female sex (P < 0.001), levodopa treatment (P < 0.001), the presence of depressed mood (P < 0.001), wearing off (P = 0.003), and dyskinesia (P = 0.005). Participants who had postural instability and gait difficulty motor subtypes had higher KPPS scores compared with those who had other subtypes. Multivariate regression analysis showed that only sex, motor subtype, depressed mood, and Non‐Motor Symptoms Scale sleep/fatigue domain scores achieved statistical significance as determinants (all P < 0.01).
Conclusion
PD‐associated pain is a frequent symptom that tends to increase in both frequency and severity as disease progresses. Risk factors for increased burden include female gender, postural instability and gait difficulty motor subtypes, mood alterations, and sleep/fatigue disturbances.
Objectives
Impulse control disorders (ICDs) are common among patients with Parkinson's disease (PD). Risk factors identified for developing ICDs include young age, family history, and impulsive ...personality traits. However, the association of these potentially disabling disorders with nondopaminergic drugs and sleep disorders has been understudied. Our objective was to examine the association between ICDs and nondopaminergic medications and sleep disorders.
Methods
We conducted an observational study of 53 patients with PD from the National Institute of Neurology and Neurosurgery. ICDs were diagnosed using the Questionnaire for Impulsive–Compulsive Disorders in Parkinson's Disease Rating Scale (QUIP‐RS). Patients underwent polysomnography screening to diagnose the presence of sleep disorders. We documented the presence of dopaminergic and nondopaminergic medications, including monoamine oxidase type B inhibitors (MAOBIs), antidepressants, sleep inductors, and antipsychotics.
Results
ICDs were reported in 18.9% of the patients (n = 10), and sleep disorders were diagnosed in 81.1% of patients (n = 43). 32.1% of the patients were on antidepressants, 17% on MAOBIs, 15.1% on sleep inductors, and 1.9% on antipsychotics. We observed that QUIP‐RS A–D subscore depended on the presence of antidepressants (p = .03) and sleep inductors (p = .02). Sleep disorders were not associated with the total QUIP‐RS score (p = .93) or QUIP‐RS A–D subscore (p = .81).
Conclusion
Antidepressants and sleep inductors were significant predictors for individual QUIP‐RS items and subscores. Our results suggest that nondopaminergic drugs commonly used for PD may be associated with impulse control disorders. We did not identify a relationship between ICDs and polysomnography‐confirmed sleep disorders in patients with PD. Larger and longitudinal studies are needed to confirm our results.

Introduction:
Coping styles have a mediating effect on several clinical outcomes. The patient–doctor relationship and the patient’s role in decision-making process might be influenced by the way the ...patient reacts to certain stressors or problems due to the evolution of their disease.
Objective:
To assess the role of coping strategies on the patient–doctor relationship and the patient’s role in decision-making in a group of people with Parkinson’s disease (PD).
Methods:
A cross-sectional study was carried out. The Coping Style Questionnaire (CSQ-40), the 9-item Patient–Doctor Relationship Questionnaire (PDRQ-9), and the 9-item Shared Decision-Making Questionnaire (SDM-Q-9) were applied.
Results:
A total of 36 women and 64 men with PD were included. The predominant coping style in women was rational. In men, the detachment style was more frequent. The SDM-Q-9 mean score was 33.2 ± 11.2 (transformed median score of 80). The PDRQ-9 average score was 2.9 ± 1 (sum score of 26.1 ± 8.7). No association was found between the CSQ-40 with the PDRQ-9 or SDM-Q-9. On the other hand, the PDRQ-9 mean score and the transformed SDM-Q-9 score highly correlated (r = 0.62, P < .001).
Conclusion:
Patient–doctor relationship and shared decision-making are independent of the coping style in people with PD.
Highlights • We assessed the usefulness of the UPSIT, B-SIT and SS-16 for PD diagnosis. • SS-16 sensitivity was 77.8% and specificity of 71.2% using a cut-off value of ≤9. • UPSIT sensitivity was 82% ...and specificity of 66% using a cut-off score of 25. • The sensitivity and specificity of the smell tests were lower than expected. • The development of a true cross-culturally smell identification test is warranted.
Monotherapy is the recommended initial treatment for early Parkinson's disease. The pharmacological options for initial treatment include dopaminergic agonists, monoamine oxidase B inhibitors, and ...levodopa formulations. Several factors should be considered when selecting the optimal treatment, such as disease severity, disease duration, age, activity level, and the risk of developing motor and non-motor complications. Early evidence on the potential role of levodopa formulations in the risk of dyskinesia led to levodopa aversion in the late 1990s and early 2000s, favoring the use of levodopa-sparing options like dopamine agonists. This shift resulted in an increase in behavioral adverse effects, such as impulse control disorders, leading to a subsequent dopamine agonist aversion in the mid-2000s. This review aims to provide a comprehensive evaluation of the existing literature regarding the benefits and drawbacks of levodopa versus levodopa-sparing strategies in drug-naive early-stage Parkinson's disease.Monotherapy is the recommended initial treatment for early Parkinson's disease.

Abstract Background Impulse control disorders (ICDs) are a relatively recent addition to the behavioral spectrum of PD-related non-motor symptoms. Social and economic factors may play a role on the ...ICD phenotype of PD patients. Objective The aim of this study is to determine the prevalence and characterize the clinical profile of ICDs in a sample of low-income, low-education PD patients with no social security benefits from a Latin American country. Methods We included 300 consecutive PD patients and 150 control subjects. The presence of ICD and related disorders was assessed using a structured interview. After the interview and neurological evaluation were concluded, all subjects completed the Questionnaire for Impulsive-compulsive Disorders in Parkinson's Disease-Rating Scale (QUIP-RS). Results Regarding ICDs and related disorders (hobbyism-punding), 25.6% ( n = 77) of patients in the PD group and 16.6% ( n = 25) in the control group fulfilled criteria for at least one ICD or related disorder ( p = 0.032). There was a statistically significant difference in the QUIP-RS mean score between PD and control subjects (5.6 ± 9.7 and 2.7 ± 4.21, p = 0.001). The most common ICD was compulsive eating for both PD (8.6%) and control (2.6%) groups. Conclusions The results of this study confirm that for this population, symptoms of an ICD are significantly more frequent in PD subjects than in control subjects. Nevertheless, socioeconomic differences may contribute to a lower overall frequency and distinct pattern of ICDs in PD patients compared with what has been reported in other countries.
•Frontal brain regions show increased EEG phase-based connectivity in Parkinson's disease (PD).•EEG connectivity and disease duration are interactive predictors of cognitive decline in PD.•Increased ...synchrony of frontal slow waves predicts cognitive decline in PD patients after less of a decade with the illness.
Cognitive decline does not always follow a predictable course in Parkinson’s disease (PD), with some patients remaining stable while others meet criteria for dementia from early stages. Functional connectivity has been proposed as a good correlate of cognitive decline in PD, although it has not been explored whether the association between this connectivity and cognitive ability is influenced by disease duration, which was our objective.
We included 30 patients with PD and 15 healthy controls (HC). Six cognitive domains were estimated based on neuropsychological assessment. Phase-based connectivity at frontal and posterior cortical regions was estimated from a resting EEG.
The PD group showed significant impairment for the executive, visuospatial, and language domains compared with HC. Increased connectivity at frontal regions was also found in the PD group. Frontal delta and theta connectivity negatively influenced general cognition and visuospatial performance, but this association was moderated by disease duration, with increased connectivity predicting worse performance after 8 years of disease duration.
Subtle neurophysiological changes underlie cognitive decline along PD progression, especially around a decade after motor symptoms onset.
Connectivity of EEG slow waves at frontal regions might be used as a predictor of cognitive decline in PD.
The wearing-off phenomenon is common in patients with Parkinson's disease. Motor and non-motor symptoms can fluctuate in relation to the "on/off" periods. To assess the impact of motor and non-motor ...wearing-off on activities of daily living and quality of life of patients with PD.
A cross-sectional study was carried out. All patients were evaluated using the Movement Disorders Society Unified Parkinson's Disease Rating Scale. Wearing-off was assessed using the Wearing-Off Questionnaire-19, and quality of life was assessed using the Parkinson's Disease Questionnaire-8.
A total of 271 patients were included; 73.4% had wearing-off; 46.8% had both motor and non-motor fluctuations. Patients with both motor and non-motor wearing-off had a worst quality of life compared with those with only motor fluctuations (p = 0.047).
Motor and non-motor fluctuations have an impact on activities of daily living and quality of life. Non-motor wearing-off may have a higher impact.
