Background And Objective: Staging Parkinson's disease (PD) with a novel simple classification called MNCD, based on four axes (Motor; Non-motor; Cognition; Dependency) and five stages, correlated with disease severity, patients' quality of life and caregivers' strain and burden. Our aim was to apply the MNCD classification in advanced PD patients treated with device-aided therapy (DAT).

Patients And Methods: A multicenter observational retrospective study of the first patients to start the levodopa-entacapone-carbidopa intestinal gel (LECIG) in Spain was performed (LECIPARK study).

The aim of this study was to report real-world evidence about the effectiveness, tolerability, and safety of LECIG in PD patients.

Methods: A multicenter observational retrospective study of the first patients who initiated LECIG in Spain was performed.

Article Synopsis
  • Current estimates of genetic variants linked to Parkinson's disease (PD) show limitations and biases across different populations, complicating patient recruitment for clinical trials focused on genetic therapies.
  • The Rostock Parkinson's disease (ROPAD) study analyzes data from 12,580 PD patients across 16 countries, revealing that 14.8% had a genetic test positive for PD-related variants, particularly in specific genes like GBA1 and LRRK2.
  • Findings indicate higher positivity rates in patients with earlier onset (age ≤ 50) or a positive family history, emphasizing the need for more extensive genetic investigation to improve patient stratification for future clinical trials.

Background: Conventional oral levodopa therapy for the treatment of Parkinson's disease can be associated with variations in plasma concentrations. Levodopa infusion strategies might provide more consistent drug delivery and fewer motor fluctuations. We aimed to assess the safety and efficacy of a continuous 24 h/day subcutaneous infusion of ND0612 (a levodopa-carbidopa solution) compared with oral immediate-release levodopa-carbidopa for the treatment of motor fluctuations in people with Parkinson's disease.

Article Synopsis
  • The DYSCOVER study compared levodopa-carbidopa intestinal gel (LCIG) to optimized medical treatment (OMT) in patients with Parkinson's disease and significant dyskinesia, finding that LCIG led to notable improvements in dyskinesia, pain, and health outcomes at 12 weeks.
  • The analysis revealed moderate-to-strong positive correlations between dyskinesia severity and both pain and health-related quality of life scores, indicating that as one worsens, so does the other.
  • Ultimately, the study suggests that addressing dyskinesia in these patients can positively impact their pain levels and overall quality of life.

Background: Apomorphine sublingual film (SL-APO) and subcutaneous apomorphine (SC-APO) have been used for the treatment of OFF episodes in Parkinson's disease (PD). No study has prospectively compared efficacy and safety of these formulations.

Objective: To compare SL-APO with SC-APO for treatment of OFF episodes in PD.

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.

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.

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.

Background: Recently, a novel simple classification called MNCD, based on 4 axes (Motor; Non-motor; Cognition; Dependency) and 5 stages, has been proposed to classify Parkinson's disease (PD).

Objective: Our aim was to apply the MNCD classification in a cohort of PD patients for the first time and also to analyze the correlation with quality of life (QoL) and disease severity.

Methods: Data from the baseline visit of PD patients recruited from 35 centers in Spain from the COPPADIS cohort fromJanuary 2016 to November 2017 were used to apply the MNCD classification.

Background And Objective: Sex plays a role in Parkinson's disease (PD) mechanisms. We analyzed sex difference manifestations among Spanish patients with PD.

Patients And Methods: PD patients who were recruited from the Spanish cohort COPPADIS from January 2016 to November 2017 were included.

Background And Purpose: Visual hallucinations (VH) and subjective cognitive complaints (SCC) are associated with cognitive impairment (CI) in Parkinson's disease. Our aims were to determine the association between VH and SCC and the risk of CI development in a cohort of patients with Parkinson's disease and normal cognition (PD-NC).

Methods: Patients with PD-NC (total score of >80 on the Parkinson's Disease Cognitive Rating Scale [PD-CRS]) recruited from the Spanish COPPADIS cohort from January 2016 to November 2017 were followed up after 2 years.

Introduction: Using microelectrodes for recording purposes in deep brain stimulation (DBS) has proven to be very useful. Their efficiency can be improved by characterising the properties of extracellular action potentials (EAPs).

Patients And Methods: We analysed the records of nine patients who underwent surgery for epilepsy or aggressiveness under general anaesthesia.

Article Synopsis
  • Dopamine replacement therapy is crucial for managing motor and nonmotor symptoms in Parkinson's disease, but treatment adjustments become necessary as the disease progresses.
  • The study aimed to validate the OPTIMIPARK questionnaire, which assesses patient symptoms, to aid clinicians in making treatment decisions for those on levodopa.
  • Results showed that the OPTIMIPARK score led to more patients needing treatment changes compared to standard evaluations, suggesting it could be a more effective tool for determining therapeutic needs in Parkinson's patients.

Background: Aggregated α-synuclein plays an important role in the pathogenesis of Parkinson's disease. The monoclonal antibody prasinezumab, directed at aggregated α-synuclein, is being studied for its effect on Parkinson's disease.

Methods: In this phase 2 trial, we randomly assigned participants with early-stage Parkinson's disease in a 1:1:1 ratio to receive intravenous placebo or prasinezumab at a dose of 1500 mg or 4500 mg every 4 weeks for 52 weeks.

Background: For specialists in charge of Parkinson's disease (PD), one of the most time-consuming tasks of the consultations is the assessment of symptoms and motor fluctuations. This task is complex and is usually based on the information provided by the patients themselves, which in most cases is complex and biased. In recent times, different tools have appeared on the market that allow automatic ambulatory monitoring.

Introduction: Deep brain stimulation (DBS) of the subthalamic nucleus is currently an evidence-based therapeutic option for motor symptoms in patients with Parkinson's disease (PD), although other non-motor symptoms can be affected by stimulation.

Aim: Our objective is to evaluate the global changes in the connectivity of the large-scale structural network in PD patients that have obtained a benefit from subthalamic DBS.

Subjects And Methods: Retrospective study of 31 subjects: 7 PD patients with subthalamic DBS (group A), 12 age and gender-matched non-operated PD (B) and 12 healthy controls (C).

Quality of life (QOL) plays an important role in independent living in Parkinson's disease (PD) patients, being crucial to know what factors impact QoL throughout the course of the disease. Here we identified predictors of QoL impairment in PD patients from a Spanish cohort. PD patients recruited from 35 centers of Spain from the COPPADIS cohort from January 2016, to November 2017, were followed up during 2 years.
