Identifying the prevalence of Parkinson's disease in Denmark using healthcare registries and self-reported survey data.

Introduction: Existing estimates of PD prevalence in Denmark are lower than those in the rest of Europe and are based on identification via single registries. Hence, are aim was to use a combined registry/self-report survey approach to identify people with PD and also investigate whether using different registry methods led to differences in the accuracy, completeness and characteristics of the identified cohorts.

Methods: This study had a cross-sectional design using routinely collected health registry data to identify adults, ≥18 years of age and resident in Denmark, with PD from either the Danish National Patient (DNP) registry or Danish Prescription Medicines (DPM) registry.

Clinical Markers of 6 Pre-dominant Coping Behaviors in Living With Parkinson Disease: A Convergent Mixed Methods Study.

People with Parkinson's disease (PwP) experience a variety of symptoms and fluctuations in these, which they have to cope with every day. In tailoring a person-centered treatment to PwP there is a lack of knowledge about the association between pre-dominant coping behaviors and clinical markers among PwP. To describe and compare specific clinical markers between 6 suggested coping behaviors.

Brain proteome profiling implicates the complement and coagulation cascade in multiple system atrophy brain pathology.

Background: Multiple system atrophy (MSA) is a rare, progressive, neurodegenerative disorder presenting glia pathology. Still, disease etiology and pathophysiology are unknown, but neuro-inflammation and vascular disruption may be contributing factors to the disease progression. Here, we performed an ex vivo deep proteome profiling of the prefrontal cortex of MSA patients to reveal disease-relevant molecular neuropathological processes.

Cerebrospinal fluid and plasma distribution of anti-α-synuclein IgMs and IgGs in multiple system atrophy and Parkinson's disease.

Introduction: Ubiquitous naturally occurring autoantibodies (nAbs) against alpha-synuclein (α-syn) may play important roles in the pathogenesis of Multiple System Atrophy (MSA) and Parkinson's disease (PD). Recently, we reported reduced high-affinity/avidity anti-α-syn nAbs levels in plasma from MSA and PD patients, along with distinct inter-group immunoglobulin (Ig)G subclass distributions. The extent to which these observations in plasma may reflect corresponding levels in the cerebrospinal fluid (CSF) is unknown.

Current assessments of motor symptoms in Parkinson's disease are often limited to clinical rating scales. To develop a computer application using the Microsoft Kinect sensor to assess performance-related bradykinesia. The developed application () was tested in patients with Parkinson's disease and healthy controls.

Life with Parkinson's Disease During the COVID-19 Pandemic: The Pressure Is "OFF".

People with Parkinson's disease (PwP) have been suggested to be more vulnerable to negative psychological and psycho-social effects of the COVID-19 pandemic. Our aim was to assess the potential impact of the COVID-19 pandemic in PwP. A Danish/Swedish cohort of 67 PwP was analysed.

TDP-43-specific Autoantibody Decline in Patients With Amyotrophic Lateral Sclerosis.

Objective: We hypothesize alterations in the quality and quantity of anti-43-kDa TAR DNA-binding protein (TDP-43) naturally occurring autoantibodies (NAbs) in patients with amyotrophic lateral sclerosis (ALS); therefore, we assessed relative binding properties of anti-TDP-43 NAbs composite in plasma from patients with ALS in comparison with healthy individuals.

Methods: ELISA competition assay was used to explore the apparent avidity/affinity of anti-TDP-43 NAbs in plasma from 51 normal controls and 30 patients with ALS. Furthermore, the relative levels of anti-TDP-43 NAbs within the immunoglobulin (Ig) classes of IgG (isotype IgG1-4) and IgMs were measured using classical indirect ELISA.

Design: Randomized controlled trial.

Setting: Patients' association.

Identification of Pre-Dominant Coping Types in Patients with Parkinson's Disease: An Abductive Content Analysis of Video-Based Narratives.

Background: People with Parkinson's disease suffer from a range of various symptoms. Altered movement patterns frequently represent the prevailing symptom experience and influence the everyday life of the affected persons.

Objective: This qualitative study explores how persons with Parkinson's disease experience everyday life with a complex symptom profile and how they manage the consequential challenges in their daily life, as well as the motivation and consequences of these coping behaviours.

"Does the Response to Morning Medication Predict the ADL-Level of the Day in Parkinson's Disease?".

Background: Individuals with Parkinson's Disease (PD) have bradykinesia during mobility tasks in the morning before intake of dopaminergic treatment and have difficulties managing Activities of Daily Living (ADLs). Early morning off (EMO) refers to off-states in the morning where the severity of bradykinesia is increased and causes a decrease in mobility related to wearing off of effects of medication. Measurements from devices capable of continuously recording motor symptoms may provide insight into the patient's response to medication and possible impact on ADLs.

Measuring movements in adolescents with psychosis using the Microsoft Kinect sensor: a pilot study exploring a new tool for assessing aspects of antipsychotic-induced parkinsonism.

Background: The assessment of motor disturbances in antipsychotic-treated adolescent patients is often limited to the use of observer-based rating scales with interobserver variability. The objectives of this pilot study were to measure movement patterns associated with antipsychotic-induced parkinsonism in young patients with psychosis and initiating/treated with antipsychotics, using a computer application connected with the Microsoft Kinect sensor (Motorgame).

Method: All participants were assessed by neurological examination, clinical side effect rating scales (Udvalg for Kliniske Undersøgelser Side Effect Rating Scale, Barnes Akathisia Rating Scale, Simpson Angus Scale (SAS), and Abnormal Involuntary Movement Scale), and the Motorgame.

Bladder training for urinary tract symptoms in Parkinson disease: A randomized controlled trial.

Objective: To assess the feasibility and efficacy of bladder training for troublesome lower urinary tract symptoms (LUTS) in Parkinson disease (PD).

Methods: In this single-center, single-blinded, randomized controlled trial, participants with a history of PD and LUTS were randomized to a 12-week bladder training program (BT) or conservative advice (CA). Outcome measures included a 3-day volume frequency diary, International Consultation on Incontinence Questionnaire (ICIQ)-Overactive Bladder Module, and ICIQ-Quality of Life Module.

Risk of Multiple System Atrophy and the Use of Anti-Inflammatory Drugs: A Danish Register-Based Case-Control Study.

Introduction: Multiple system atrophy (MSA) is a rare rapidly progressive atypical Parkinson disorder presenting clinically with parkinsonism and/or a cerebellar syndrome in combination with dysautonomia. Severe neuroinflammation develops along with hallmark neuropathological changes, and as in Parkinson's disease, intake of anti-inflammatory medication has been hypothesized to be protective for development of disease. We aimed to investigate if use of non-aspirin nonsteroidal anti-inflammatory drugs (NSAIDs), low-dose aspirin, or statins were associated with a reduced risk of MSA.

Distinct Autoimmune Anti-α-Synuclein Antibody Patterns in Multiple System Atrophy and Parkinson's Disease.

Aggregation of alpha-synuclein (α-syn) is considered to be the major pathological hallmark and driving force of Multiple System Atrophy (MSA) and Parkinson's disease (PD). Immune dysfunctions have been associated with both MSA and PD and recently we reported that the levels of natural occurring autoantibodies (NAbs) with high-affinity/avidity toward α-synuclein are reduced in MSA and PD patients. Here, we aimed to evaluate the plasma immunoglobulin (Ig) composition binding α-syn and other amyloidogenic neuropathological proteins, and to correlate them with disease severity and duration in MSA and PD patients.

Increased prefrontal cortex interleukin-2 protein levels and shift in the peripheral T cell population in progressive supranuclear palsy patients.

Accumulating evidence suggests neuroinflammation to be an integrated feature of neurodegeneration. Profiling inflammatory mediators across diseases may reveal common and disease-specific signatures. Here, we focused on progressive supranuclear palsy (PSP), a tauopathy presenting motor and cognitive dysfunction.

The biomarker potential of cell-free microRNA from cerebrospinal fluid in Parkinsonian Syndromes.

Background: MicroRNAs are small noncoding RNAs involved in the post-transcriptional regulation of protein synthesis. Extracellular microRNAs are accessible in a stable form in biofluids.

Objectives: The aim was to identify individual microRNAs and/or subsets of microRNAs in CSF with biomarker potential and thus identify specific putative pathophysiological pathways.

Association between the reported intensity of an acute symptom at first prehospital assessment and the subsequent outcome: a study on patients with acute chest pain and presumed acute coronary syndrome.

Background: To decrease the morbidity burden of cardiovascular disease and to avoid the development of potentially preventable complications, early assessment and treatment of acute coronary syndrome (ACS) are important. The aim of this study has therefore been to explore the possible association between patients' estimated intensity of chest pain when first seen by the ambulance crew in suspected ACS, and the subsequent outcome before and after arrival in hospital.

Methods: Data was collected both prospectively and retrospectively.

Cerebrospinal fluid pro-inflammatory cytokines differentiate parkinsonian syndromes.

Introduction: Neuroinflammation has been established to be part of the neuropathological changes in Parkinson's disease (PD) and atypical parkinsonism (APD). Activated microglia play a key role in neuroinflammation by release of cytokines. Evidence of the disparity, if any, in the neuroinflammatory response between PD and APD is sparse.

[Challenges in the differential diagnoses of parkinsonism].

Parkinsonism (PD) is the clinical syndrome of bradykinesia combined with rigidity and/or tremor at rest. These are the defining characteristics of PD, but they are present in many other diseases of the brain. The most frequent differential diagnosis of PD are the atypical parkinsonian syndromes and the conditions presenting with mainly lower body parkinsonism.

Cytokine profiling in the prefrontal cortex of Parkinson's Disease and Multiple System Atrophy patients.

Parkinson's Disease (PD) and Multiple System Atrophy (MSA) are neurodegenerative diseases characterized neuropathologically by alpha-synuclein accumulation in brain cells. This accumulation is hypothesized to contribute to constitutive neuroinflammation, and to participate in the neurodegeneration. Cytokines, which are the main inflammatory signalling molecules, have been identified in blood and cerebrospinal fluid of PD patients, but studies investigating the human brain levels are scarce.
