Objective: The objective of this study was to clarify the relationship between autonomic and non-autonomic non-motor symptoms in patients with Parkinson’s disease (PD). Methods: Sixty-five PD patients were included in this study (27 men and 38 women; aged 68.5 ± 10.0; Hoehn and Yahr (HY) stage 2.6 ± 1.1). The autonomic symptoms were evaluated by the Japanese version of the Scales for outcomes in PD autonomic (SCOPA-AUT) questionnaire. The patients were assessed with the mini-mental state examination (MMSE), PD sleep evaluation scale-2 (PDSS-2), Epworth sleepiness scale (ESS) and Beck’s depression inventory II (BDI-II). The Non-Motor Symptom Scale (NMSS) total scores and subscores of non-autonomic non-motor symptom domains (sleep/fatigue, mood/cognition, perceptual problems/hallucination, and attention/memory) were evaluated. A dopamine transporter (DAT) scan, metaiodobenzylguanidine (MIBG) myocardial scintigraphy, and card type olfactory identification test (open essence [OE, Wako]) were performed. Results: The SCOPA-AUT total score was positively correlated with the disease duration, HY stage, levodopa equivalent dose, PDSS-2, ESS, BDI-II and non-autonomic NMSS and inversely correlated with the MMSE. The high-SCOPA-AUT group (≥9) had lower MMSE scores and higher PDSS-2, ESS, BDI-II and non-motor NMSS scores than the low-SCOPA-AUT group (< 9). The DAT scan, MIBG uptake and OE score did not differ between the groups. In a stepwise linear regression analysis, which excluded possibly overlapping items among the scales, the subtotals of PDSS-2 items, except for item 8 (nocturia), (p < 0.0001) and non-autonomic NMSS domains (p = 0.00040) were significant predictors of the total SCOPA-AUT score. Conclusion: Our study shows significant correlations among autonomic symptoms, PD-related sleep problems and non-autonomic non-motor symptoms in PD patients.

Non Motor Symptoms

Parkinson’s disease (PD) is primarily considered as a motor disorder but there is increasing recognition of the wide range of non-motor symptoms (NMS), such as low mood, pain, apathy, fatigue and sleep problems, which may be experienced by PD patients across the spectrum of the disease. Notably, NMS often occur before motor symptoms develop and are known to place a significant burden on health-related quality of life (HRQoL) of the person with PD. Commonly, NMS go undiagnosed by the clinician and are therefore undertreated; however, to optimise patient outcomes, both motor and non-motor aspects of PD need to be recognised and managed effectively. The 10th International Congress on Non-Motor Dysfunctions in Parkinson’s Disease and Related Disorders held in Nice, France, in December 2014, offered the opportunity to look further into the dopaminergic basis of NMS and how this may affect clinical management. Britannia arranged an international faculty, chaired by Professor Amos Korczyn (Tel Aviv, Israel), to review the latest developments in our understanding of the underlying aetiology and clinical burden of non-motor features in PD that will ultimately help inform clinical practice. Surveys indicate that NMS have an extremely high prevalence among PD patients and evidence now suggests that it is the total ‘burden’ of NMS, combining frequency and severity, and not just the occurrence of individual NMS such as depression, which is the major determinant of a patient’s HRQoL. Recognising the significant contribution of NMS to the total clinical picture in PD, in order to provide a more comprehensive grading of PD severity, it is now proposed that the clinical assessment of PD patients needs a combined approach using for example the validated Non-motor Symptoms Scale (NMSS) to assess total NMS burden in addition to classic motor symptom scoring. Recent data from newly diagnosed PD patients also suggests there are different subtypes of PD that may have implications for both clinical trial design and the selection of therapy. Cognitive impairment often occurs in patients with PD, even in early disease, progressing to PD dementia in a substantial proportion of patients, which can limit therapeutic options. Posterior cortical dysfunction is a negative predictor of the progression of PD with mild cognitive impairment to PD dementia. Pronounced nigrostriatal denervation is characteristic of PD; however, cholinergic changes are also observed. Cholinergic depletion starts early in the disease process and by the time PD dementia develops patients will have a significant cholinergic deficit in various cortical regions. Current research is focused on the potential to reduce cognitive decline by decreasing beta-amyloid plaques.

Parkinson's disease is a disease of motor manifestations but non-motor symptoms are also common in Parkinson's disease. Little emphasis is put on non-motor symptoms of PD and there is little data on the relationship of non-motor symptoms to different aspects of the patient and the disease. In this study the relationship of non-motor symptoms to age at onset, duration and stage of the disease, and dose and duration of levodopa use are studied.128 patients of PD were studied for non-motor symptoms. 111 patients had different types of sensory, autonomic or psychiatric symptoms. Sensory and autonomic symptoms were significantly more common in patients with early age of disease onset and more prolonged duration of the disease, but psychiatric symptoms had no relationship with these factors. In this study it was also found that the frequencies of non-motor symptoms were related to the stage of the disease, longer the duration of the disease more and more non-motor symptoms appear so that 100% patients in stage 5 of the disease had non-motor symptoms. Also sensory and autonomic symptoms were significantly more common in patients with longer duration and higher dose of levodopa use but psychiatric symptoms were significantly commoner in patients with prolonged duration of levodopa use but not to dose of levodopa used.   doi: 10.3329/taj.v21i1.3211 TAJ 2008; 21(1): 12-17

Introduction: The aim of the present study was to examine the frequency of self-reported sleep problems and their associated factors in a large cohort of PD patients. Methods: PD patients and controls, recruited from 35 centers of Spain from the COPPADIS cohort were included in this cross-sectional study. Sleep problems were assessed by the Spanish version of the Parkinson’s disease Sleep Scale version 1 (PDSS-1). An overall score below 82 or a score below 5 on at least 1 item was defined as sleep problems. Results: The frequency of sleep problems was nearly double in PD patients compared to controls: 65.8% (448/681) vs 33.5% (65/206) (p < 0.0001). Mean total PDSS score was lower in PD patients than controls: 114.9 ± 28.8 vs 132.8 ± 16.3 (p < 0.0001). Quality of life (QoL) was worse in PD patients with sleep problems compared to those without: PDQ-39SI, 19.3 ± 14 vs 13 ± 11.6 (p < 0.0001); EUROHIS-QoL8, 3.7 ± 0.5 vs 3.9 ± 0.5 (p < 0.0001). Non-motor symptoms burden (NMSS; OR = 1.029; 95%CI 1.015–1.043; p < 0.0001) and impulse control behaviors (QUIP-RS; OR = 1.054; 95%CI 1.009–1.101; p = 0.018) were associated with sleep problems after adjustment for age, gender, disease duration, daily equivalent levodopa dose, H&Y, UPDRS-III, UPDRS-IV, PD-CRS, BDI-II, NPI, VAS-Pain, VAFS, FOGQ, and total number of non-antiparkinsonian treatments. Conclusion: Sleep problems were frequent in PD patients and were related to both a worse QoL and a greater non-motor symptoms burden in PD. These findings call for increased awareness of sleep problems in PD patients.

Non Motor Symptoms

Background: Parkinson’s disease is a common neurodegenerative movement disorder characterised by motor symptoms of rest tremor, bradykinesia, rigidity and postural instability and non-motor symptoms (NMS) which include neuropsychiatric symptoms, sleep disturbances, autonomic symptoms, sensory symptoms and symptoms of mixed aetiology. Parkinson’s Disease Non Motor Group (PD-NMG) devised a comprehensive clinic-based self-completed NMS questionnaire that allows easy identification of NMS by the physician. Most NMS have a poor response to dopaminergic therapy as it is due to dysfunction of the serotonergic and noradrenergic pathways. Treatment of these nonmotor symptoms help in improving the quality of life in patients with Parkinson’s disease.Methods: There were 100 patients with Parkinson’s disease who had presented to our neuromedicine movement clinic were included in the study. Patients were diagnosed as PD based on UK Parkinson’s disease brain bank criteria. The inclusion criteria were diagnosis as PD, age >18 yrs, inclusion of both males and females and consent for the study. Patients with atypical parkinsonism and secondary parkinsonism, stroke, intake of antipsychotics were excluded from the study. Non motor symptom questionnaire was given to the study group and frequency of occurrence of each non motor symptoms and their predominance in both males and females were studied. The frequency of each NMS was calculated by computing the number of yes response and calculating the percentage related to the number of patients in the sample. Analysis was done to calculate the frequency of all NMS among the enrolled patient.Results: Nocturnal sleep disturbances (43%) were most common followed by constipation (29%).The most common non motor symptoms in males were constipation (20%), urinary urgency (18%) and nocturia (11%).The most common non motor symptoms in females were nocturnal sleep disturbance (25%), feeling sad (19%), unexplained pains (17%) and being anxious (13%).Conclusions: Non motor symptom questionnaire helps in screening patients with Parkinson’s disease of non-motor symptoms and aims at providing holistic treatment improving the quality of life.

Background: Exercise is an important treatment for Parkinson's disease (PD). Therefore, recognizing determinants of exercise behavior for PD based on disease stage is essential. We sought to find whether the determinants differ based on presence of postural instability (PI), which is indicative of disease stage in PD.Methods: We enrolled patients at Samsung Medical Center from September 2019 to November 2020, who had the ability to perform exercise [modified Hoehn and Yahr (HY) stage ≤ 3]. All the motor and non-motor symptoms were investigated. The exercise of the PD patients was evaluated using the Physical Activity Scale of the Elderly (PASE)-leisure score. We classified patients into PD without PI (HY stage 1 – 2) and PD with PI (HY stage 2.5 – 3) groups. Multivariate linear regression was performed using backward elimination in each group to determine factors associated with PASE-leisure score.Results: A total of 233 patients were enrolled. In the PD without PI group (n = 177), the positive determinant of exercise was Activities-Specific Balance Confidence (ABC) score (β = 0.142, p = 0.032), and the negative determinants were fatigue score (β = −0.228, p = 0.018), female (β = −6.900, p = 0.016) and currently employed status (β = −6.072, p = 0.046). In the PD with PI group (n = 56), the positive determinant was non-motor symptom scale (NMSS) score (β = 0.221, p = 0.017) and disease duration (β = 1.001, p = 0.036), while the negative determinants were UPDRS part 3 score (β = −0.974, p &lt; 0.001), UPDRS part 4 score (β = −2.192, p = 0.002), and age (β = −1.052, p &lt; 0.001).Conclusion: Different motor and non-motor symptoms were associated with the exercise in PD patients with and without PI. When encouraging PD patients to exercise, personalized and different strategies should be applied based on the presence of PI.

Non Motor Symptoms

Nonmotor symptoms of Parkinson's disease (PD) may emerge secondary to the underlying pathogenesis of the disease, while others are recognized side effects of treatment. Inevitably, there is an overlap as the disease advances and patients require higher dosages and more complex medical regimens. The non-motor symptoms that emerge secondary to dopaminergic therapy encompass several domains, including neuropsychiatric, autonomic, and sleep. These are detailed in the paper. Neuropsychiatric complications include hallucinations and psychosis. In addition, compulsive behaviors, such as pathological gambling, hypersexuality, shopping, binge eating, and punding, have been shown to have a clear association with dopaminergic medications. Dopamine dysregulation syndrome (DDS) is a compulsive behavior that is typically viewed through the lens of addiction, with patients needing escalating dosages of dopamine replacement therapy. Treatment side effects on the autonomic system include nausea, orthostatic hypotension, and constipation. Sleep disturbances include fragmented sleep, nighttime sleep problems, daytime sleepiness, and sleep attacks. Recognizing the non-motor symptoms that can arise specifically from dopamine therapy is useful to help optimize treatment regimens for this complex disease.

Background and Purpose: The unilateral onset and persistent asymmetry of motor symptoms are important characteristics of Parkinson's disease (PD). By using scales and wearable sensors, this study explored whether motor symptom laterality could affect non-motor symptom and gait performance.Methods: A total of 130 right-handed patients with PD were enrolled in our study and were divided into two groups according to the side of predominant motor symptom presentation by using the Unified Parkinson's Disease Rating Scale part III. We measured the non-motor symptoms with the Non-motor symptoms Scale, sleep quality with the Parkinson's Disease Sleep Scale and Pittsburgh sleep quality index, cognitive function with the Mini-mental State Examination and Montreal Cognitive Assessment, quality of life with the Parkinson's Disease Questionnaire-39, and the severity of anxiety and depression with the Hamilton Anxiety Scale and Hamilton Depression Scale, respectively. All participants underwent the instrumented stand and walk test, and gait data were collected using a set of JiBuEn gait analysis system.Results: We observed that left-dominant symptom PD patients (LPD) were associated with a greater impairment of sleep quality than right-dominant symptom PD patients (RPD). We found no difference between LPD and RPD in terms of gait performance. However, compared with the severe asymmetry RPD patients (RPD-S), severe asymmetry LPD patients (LPD-S) showed a shorter stride length and decreased range of motion of hip joints.Conclusions: In this study, LPD was associated with a more severe sleep-related dysfunction than RPD. In addition, LPD-S exhibited more gait impairments than RPD-S. Considering that motor symptom laterality may affect the non-motor symptom and gait performance, it should be taken into account when evaluating and treating PD patients.

ABSTRACTBackgroundThe underlying pathophysiology of swallowing and chewing difficulties is multifactorial and evidence clarifying the precise mechanisms are scarce. Dysfunction in dopamine-related and non-dopamine-related pathways, changes in cortical networks related with swallowing and peripheral mechanisms have been implicated in the pathogenesis of swallowing difficulties. We aimed at investigating whether swallowing and chewing difficulties are associated with presynaptic dopaminergic deficits, faster motor symptom progression and cognitive decline in a population of early drug-naïve patients with Parkinson’s disease.MethodsBy exploring the database of Parkinson’s Progression Markers Initiative we identified forty-nine early drug-naïve Parkinson’s disease patients with swallowing difficulties. Swallowing and chewing impairment was identified with SCOPA-AUT question 1 (answer regularly) and was assessed with MDS-UPDRS Part-II, Item 2.3 (Chewing and Swallowing). We compared Parkinson’s disease patients with swallowing and chewing difficulties to Parkinson’s disease patients without difficulties, and investigated differences in striatal [123I]FP-CIT single photon emission computed tomography levels. Using Cox proportional hazards analyses, we also evaluated whether swallowing impairment can predict motor deterioration and cognitive dysfunction.ResultsPatients with Parkinson’s disease, harbored a greater deterioration regarding motor and non-motor symptoms and decreased [123I]FP-CIT binding when compared with patients without swallowing and chewing impairment. Higher burden of swallowing and chewing dysfunction (MDS-UPDRS-II, item 2.3) was correlated with lower [123I]FP-CIT uptakes within the striatum (rs=−0.157; P=0.002) and the caudate (rs=−0.156; P=0.002). The presence of swallowing and chewing difficulties was not a predictor of motor progression (Hazard ratio [HR]: 1.143, 95% confidence interval [CI]: 0.848–1.541; P=0.379) or cognitive decline (HR: 1.294, 95% CI: 0.616–2.719; P=0.496).ConclusionsSwallowing and chewing impairment is associated with decreased presynaptic dopaminergic integrity within caudate and greater motor and non-motor symptoms burden in early drug-naïve PD.Author contributionsS.P. and M.P. conceived the study, conceptualized the experimental design.

Objective: Constipation is one of the most frequent non-motor symptoms (NMS) in Parkinson's disease (PD), causing great disturbance to patients. The present study investigated the prevalence and the clinical features of constipation in patients with PD and explored the difference between prodromal and clinical constipation of PD.Methods: A total of 186 patients with PD were recruited into this study. Subjective constipation was defined by ROME III criteria. Demographic and PD-related clinical information of the participants were collected. The PD patients were objectively assessed by a spectrum of rating scales of motor symptoms, non-motor symptoms, and quality of life.Results: In total, 51.61% (96/186) of PD patients suffer from constipation. Compared with patients without constipation, the patients with constipation were prone to have restless leg syndrome, depression, and anxiety and have higher scores of the non-motor symptoms scale. Among patients with constipation, 21.88% (21/96) patients had constipation in prodromal stage. Compared with patients with constipation in clinical stage, patients with prodromal constipation had a lower age of constipation onset (56.48 ± 9.63 and 65.26 ± 8.42, χ2 = 4.091, P &lt; 0.001), longer timespan from constipation onset to motor symptom onset (6.62 ± 3.91 and 3.18 ± 2.13, χ2 = −3.877, P = 0.001). Patients with prodromal constipation were predominantly tremor onset (χ2 = 4.405, P = 0.044) and usually had a better quality of life [28 (14.50–37.5) and 40 (25.0–55.0), χ2 = 2.011, P = 0.046]. Depression was the only risk factor of constipation in PD patients. Body mass index, depression, and anxiety were factors that affected the life quality in patients with constipation.Conclusions: Our results supported the high incidence of constipation in patients with PD and that, in some patients, constipation occurred before the onset of motor symptoms. The specific clinical characteristics of patients with constipation and with prodromal constipation help to make early diagnosis, to discover the relationship between constipation and PD, and to further explore the pathogenesis of this degenerative disease.

Background: Pain is a disabling and often underestimated non-motor symptom (NMS) detrimentally affecting the quality of life of patients with Parkinson’s disease (PD). Objective: Here, we conducted a cross-sectional, observational international study on 167 patients with idiopathic PD in order to analyze the potential relationship between pain and other NMS. Methods: Subjects were assessed with the Unified Parkinson’s Disease Rating Scale (UPDRS) part III, Hoehn and Yahr (H&Y) stage, King’s Parkinson’s Disease Pain Scale (KPPS), Brief Pain Inventory (BPI), Non-Motor Symptoms Scale (NMSS), and Beck Depression Inventory (BDI). Spearman’s rank correlation coefficient, multiple regression and multiple index-based clustering algorithms were used for data analysis. Results: The prevalence of pain was 88.6%, was not correlated with age, motor severity (UPDRS part III) or disease duration, whereas a weak correlation with female gender and H&Y stage >2.5 was found. Multiple NMS correlated significantly with pain. Specifically, sleep disturbance had the strongest correlation with pain, followed by depression, gastrointestinal and cardiovascular disturbances. Further analyses showed that sleep and cardiovascular disturbance were independently associated with pain, and that these symptoms clustered together in a subset of PD patients. The relationship between pain, sleep and dysautonomia persisted independently from dopamine replacement therapy. Conclusion: Our study suggests that sleep disruption and cardiovascular disturbance are associated with pain in PD, and possibly identifies a specific subtype within PD patients with pain. Our data also indicate that sleep disruption, pain and dysautonomia may have a common pathophysiology, possibly involving non-dopaminergic pathways.
