Introduction: Non-motor symptoms are underrecognized features of Parkinson’s disease that impair quality of life and increase mortality. In this study, we aim to translate, adapt and validate the European Portuguese version of the “Non-Motor Symptoms Questionnaire”, which has proven to be a valid and reliable measurement tool of non-motor symptoms in other languages.Material and Methods: Acceptability was evaluated regarding the range of values, ceiling and floor effects. Reliability was measured in terms of internal consistency (Cronbach’s alpha) and reproducibility (intra-class correlation coefficient). For criterion validity analysis, Movement Disorders Society – Unified Parkinson’s Disease Part I domains’ scores were compared to those of the “Non-Motor Symptoms Questionnaire”. For convergent validity, correlations between the “Non-Motor Symptoms Questionnaire” and the Movement Disorders Society – Unified Parkinson’s Disease Part III, Mini-Mental State Examination score, disease duration, and severity were obtained.Results: Seventy nine Parkinson’s disease patients were recruited, with a mean age of 67.2 ± 10.7 years and a disease duration of 10.8 ± 8.8 years. The European Portuguese version of the “Non-Motor Symptoms Questionnaire” total score was free of significant ceiling and floor effects. With the exception of the cardiovascular domain, adequate overall internal consistency was achieved. The questionnaire domains and the corresponding Movement Disorders Society – Unified Parkinson’s Disease Part I dimensions were significantly correlated, although the total questionnaire score was modestly correlated with disease duration and severity, motor and non-motor symptoms severity and cognitive dysfunction.Discussion: This is the first study to translate, adapt and validate a widely used screening instrument of non-motor symptoms of European Portuguese speaking Parkinson’s disease patients.Conclusion: The European Portuguese version of “Non-Motor Symptoms Questionnaire” is a valid and reliable tool for screening nonmotor symptoms in patients with Parkinson’s disease.

ABSTRACT Falls are common among persons with Parkinson's disease (PD). On the other hand, predicting falls is complex as there are both generic and PD-specific contributors. In particular, the role of non-motor symptoms has been less studied. Objective: The objective of this study was to identify the role of non-motor predictors of falling in persons with PD (PwP). Methods: A cross-sectional study was carried out in PwP recruited from a movement disorders clinic. Clinical and demographical data were collected. All PwP were assessed using the Movement Disorders Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) and the Non-Motor Symptoms Scale (NMSS). Variables were assessed at the bivariate level. Significant variables were put into a logistic regression model. Results: A total of 179 PwP were included. Overall, 16.8% of PwP had fallen in the past 12 months, with 53.3% of them being recurrent fallers. The mean number of monthly falls was 2.5 ± 3.3. Factors associated with falling in the bivariate analysis included the disease duration, Hoehn and Yahr stage, MDS-UPDRS part I and II, postural instability/gait disturbance (PIGD) subtype, NMSS urinary domain, NMSS miscellaneous domain, and non-motor severity burden (all p-values < 0.05). After multivariate analysis, only the disease duration (p = 0.03) and PIGD (p = 0.03) remained as independent risk factors. Conclusion: Disease duration and the PIGD subtype were identified as relevant risk factors for falls in PwP Non-motor symptoms appear to have a less important role as risk factors for falls.

Abstract There is an increasing recognition of the significant non-motor symptoms that burden people with Parkinson’s disease. As such, there is a pressing need to better understand and investigate the mechanisms underpinning these non-motor deficits. The electrical activity within the brains of people with Parkinson’s disease is known to exhibit excessive power within the beta range (12–30 Hz), compared with healthy controls. The weight of evidence suggests that this abnormally high level of beta power is the cause of bradykinesia and rigidity in Parkinson’s disease. However, less is known about how the abnormal beta rhythms seen in Parkinson’s disease impact on non-motor symptoms. In healthy adults, beta power decreases are necessary for successful episodic memory formation, with greater power decreases during the encoding phase predicting which words will subsequently be remembered. Given the raised levels of beta activity in people with Parkinson’s disease, we hypothesized that the necessary decrease in power during memory encoding would be diminished and that this would interfere with episodic memory formation. Accordingly, we conducted a cross-sectional, laboratory-based experimental study to investigate whether there was a direct relationship between decreased beta modulation and memory formation in Parkinson’s disease. Electroencephalography recordings were made during an established memory-encoding paradigm to examine brain activity in a cohort of adults with Parkinson’s disease (N = 28, 20 males) and age-matched controls (N = 31, 18 males). The participants with Parkinson’s disease were aged 65 ± 6 years, with an average disease duration of 6 ± 4 years, and tested on their normal medications to avoid the confound of exacerbated motor symptoms. Parkinson’s disease participants showed impaired memory strength (P = 0.023) and reduced beta power decreases (P = 0.014) relative to controls. Longer disease duration was correlated with a larger reduction in beta modulation during encoding, and a concomitant reduction in memory performance. The inability to sufficiently decrease beta activity during semantic processing makes it a likely candidate to be the central neural mechanism underlying this type of memory deficit in Parkinson’s disease. These novel results extend the notion that pathological beta activity is causally implicated in the motor and (lesser appreciated) non-motor deficits inherent to Parkinson’s disease. These findings provide important empirical evidence that should be considered in the development of intelligent next-generation therapies.

Introduction: Mutations in the Parkin gene are the most common cause of autosomal recessive early-onset Parkinson's disease (PD). However, little is known about the quality of life (QoL) in Parkin-related PD. Here, we investigated the patterns of QoL in newly diagnosed Parkin-related PD patients.Methods: Newly diagnosed PD patients (diagnosis made within 12 months) who had an age of onset (AOO) below 40 and underwent a PD-related genetic testing, were recruited (n = 148). Among them, 24 patients carried bi-allelic variants in Parkin (PD-Parkin) and 24 patients did not have any known causative PD mutations, or risk variants (GU-EOPD). The clinical materials, relevant factors and determinants of QoL were analyzed.Results: PD-Parkin patients had a younger AOO (p = 0.003) and longer disease duration (p = 0.005). After adjustment for AOO and disease duration, more dystonia (p = 0.034), and worse scores of non-motor symptoms including Beck depression inventory (BDI, p = 0.035), Epworth sleepiness scale (ESS, p = 0.044), and subdomains of depression/anxiety (p = 0.015) and sleep disorders (p = 0.005) in Non-motor symptoms questionnaire, were found in PD-Parkin comparing with GU-EOPD. PD-Parkin patients had poorer QoL (adjusted p = 0.045), especially in the mobility (adjusted p = 0.025), emotional well-being (adjusted p = 0.015) and bodily discomfort dimensions (adjusted p = 0.016). BDI scores (p = 0.005) and ESS scores (p = 0.047) were significant determinants of QoL in PD-Parkin.Conclusion: Newly diagnosed PD-Parkin patients showed worse QoL. More depression and excessive daytime sleepiness predicted worse QoL. For clinicians, management of depression and excessive daytime sleepiness is suggested to better improve QoL in patients with Parkin mutations.

AbstractNonmotor symptoms (NMSs) cause major burden in patients with Parkinson’s disease (PD). Previous NMSs progression studies mostly focused on the prevalence. We conducted a longitudinal study to identify the progression pattern by the severity. PD patients recruited from the outpatient clinics of a tertiary medical center were evaluated by the Unified Parkinson's Disease Rating Scale and Non-Motor Symptoms Scale (NMSS). A retrospective study with three-step analysis was performed. Step 1, the NMSs severity was compared among patients stratified by disease duration every 2 years up to 10 years. Step 2, patients with repeated tests in 2 years were categorized into 4 groups by the diseased duration of every 5 years. Step 3, the NMSS score changes in 6 years follow-up were determined, and the dosage of anti-PD drugs was compared to the NMSs severity changes. 676 patients completed the step 1 analysis, which showed a trend of NMSs worsening but not significant until the disease duration longer than 4–6 years. Furthermore, the severity did not change between repeated evaluations in 2 years in all patients. The progression became apparent after 6 years. Individual symptoms had different progression patterns and the increment of medications was independent to NMSs evolution. We demonstrated the NMSs severity progression in Taiwanese PD patients and the independence of the medications and NMSs progression.

Non Motor Symptoms

Background: Parkinson’s disease (PD) is a neurodegenerative condition with a diverse and complex pattern of motor and non-motor symptoms which change over time with disease duration. Objective: The aims of the present study were to discover what symptoms matter most to people with the condition and to examine how these priorities change with disease duration. Methods: A simple free-text online survey (using SmartSurvey) was developed by Parkinson’s UK, which asked participants to identify up to three aspects of the condition they would most like to see improvement in. Results: 790 people participated reporting 2,295 issues related to PD which were grouped into 24 broad symptom domains. Of these, 1,358 (59.1%) were categorised as motor symptoms, 859 (37.4%) as non-motor issues and 78 (3.4%) as medication problems. This study reveals how certain features of PD become more or less important to patients as the condition progresses. Non-motor symptoms were highly cited from the very earliest stages of PD. Problems with walking, balance and falls, speech problems, freezing and dyskinesia become increasingly important as the condition progresses whereas tremor, stiffness and psychological health become decreasingly important as the condition progresses. Conclusions: The data suggest that the priorities of people affected by PD for improving life are personal and change with duration of the condition. These findings have implications for developing person-centred management and care, as well as for directing future research to improve quality of life.

ABSTRACT Objective Patients with Parkinson’s disease (PD) may present with unusual motor and non-motor symptoms and signs in the early stage of the disease. Methods Cases were collected over a five-year period at two tertiary movement disorders clinics. All had a diagnosis of PD with unusual presentations defined retrospectively as the presence of complaints not objectively related to any of the classic cardinal signs of parkinsonism or the typical early non-motor features of PD. Results A total of 15 early PD patients fulfilled the proposed criteria, presenting with symptoms such as atypical tremors, shoulder pain, signs related to the rigid akinetic syndrome, as well as cases of asthenia, rhinorrhea, parosmia, dysgeusia, nocturnal sialorrhea, and color discrimination disorders. Conclusions Unusual motor and non-motor symptoms and signs in the early stage of PD can be difficult to interpret. Specialists should be aware of these conditions as clues to a potential diagnosis.

Despite the continuous development of diagnosis and treatment of patients with Parkinson’s disease and the arrival of new therapeutic options in recent years the treatment and care of people with Parkinson’s disease especially in the advanced stage remains a major challenge for neurologists specialized in movement disorders. The treatment of Parkinson’s disease is adversely affected by several factors: the disease progresses relentlessly, the symptoms and rate of progression, other concomitant non-motor symptoms, and the appearance of complications caused by treatment show great heterogeneity. Based on all these factors it is difficult to develop and apply a uniform routine therapeutic guideline. This summary seeks to shed light on aspects of the treatment of Parkinson’s disease particularly in advanced-stage cases drawing on data from a professional college recommendation and the literature.

Parkinson’s disease (PD) is a neurodegenerative disease with a wide range of symptom presentations. The purpose of this research was to compare self-reported motor and non-motor symptoms of PD by sex and disease duration. This study was a cross-sectional descriptive survey in community-dwelling people with PD. A total of 141 participants (64.6% response rate; 59.6% men; Mage = 69.7 years) were included. Males reported more rigidity, speech problems, sexual dysfunction, memory problems, and socializing problems than females. The number of motor symptoms in three groups divided by increments of 5 years was significantly increased. Postural instability, freezing, off periods, dyskinesia, speech problems, and hallucinations/psychosis were significantly increased as the disease duration increased. Thorough assessment of motor and non-motor symptoms could decrease the risk of inadequate symptom management. Provision of information regarding PD symptoms at each stage may help people with PD and their caregivers in planning their future care and life.
