BACKGROUND: Pain is a major non motor symptom that contributes to impaired quality of life in PD. However, its mechanism is unknown. OBJECTIVES AND METHODS: We sought to identify the pain phenotypes and parallel changes in spinal integration of peripheral stimuli in a rat model of PD induced by lesions of SN dopamine neurons, using behavioral plantar and von Frey tests as well as electrophysiology of the dorsal horn. RESULTS: We show that dopamine depletion by 6-OHDA induced hypersensitivity to mechanical and thermal stimuli...

BACKGROUND: Parkinson's disease demonstrates a spectrum of motor and non-motor symptoms. Falling is common and disabling. Current medical management shows minimal impact to reduce falls or fall-related risk factors, such as deficits in gait, strength, and postural instability. Despite evidence supporting rehabilitation in reducing fall risk factors, the most appropriate intervention to reduce overall fall rate remains inconclusive. This article aims to 1) synthesise current evidence and conceptual models of falls rehabilitation in Parkinson's in a narrative review; and based on this evidence, 2) introduce the treatment protocol used in the falls prevention and multi-centre clinical trial "PDSAFE"...

Parkinson's disease (PD) is characterised by non-motor symptoms including sleep and circadian disruption. Melanopsin-expressing intrinsically photosensitive Retinal Ganglion Cells (ipRGC) transmit light signals to brain areas controlling circadian rhythms and the pupil light reflex. To determine if non-motor symptoms observed in PD are linked to ipRGC dysfunction, we evaluated melanopsin and rod/cone contributions to the pupil response in medicated participants with PD (n = 17) and controls (n = 12)...

Parkinson disease (PD) affects people of all races and ethnicity worldwide. PD is a multineurotransmitter and multisystem disorder and our current concept of the natural history of PD has changed considerably over the past decades. Many aspects of this heterogeneous condition still remain unexplained; one aspect that is poorly studied is the role of ethnicity and manifest motor and non-motor PD. Some preliminary data suggest that the prodromal risk of developing PD, clinical symptom expression and the experience of living with the condition may vary between different ethnic groups...

Most patients with Parkinson disease (PD) have non-motor symptoms (NMS), and on average these can range from four to 19 different symptoms. NMS dominate the prodromal phase of PD and some may serve as clinical biomarkers of PD. NMS can be dopaminergic, non-dopaminergic, of genetic origin or drug induced. Clinical assessment of NMS should include the NMS Questionnaire (completed by patients) for screening, as recommended by the International Parkinson and Movement Disorders Society and other international societies...

Motor aspects of Parkinson's disease, such as fluctuations and dyskinesia, can be reliably evaluated using a variety of "wearable" technologies, but practical guidance on objective measurement (OM) and the optimum use of these devices is lacking. Therefore, as a first step, a panel of movement disorder specialists met to provide guidance on how OM could be assessed and incorporated into clinical guidelines. A key aspect of the incorporation of OM into the management of Parkinson's disease (PD) is defining cutoff values that separate "controlled" from "uncontrolled" symptoms that can be modified by therapy and that relate to an outcome that is relevant to the person with PD (such as quality of life)...

Parkinson's disease (PD) is the second most common neurodegenerative disorder and it is characterized by progressive physical disability along with a variety of non-motor symptoms. Drugs that replenish dopamine can partly alleviate the motor symptoms; however, they do not cure the disease itself. Therefore, there is an urgent need for disease modifying therapies that would delay or prevent neurodegeneration. Increasing evidence suggests that α-synuclein, a key molecule in PD, is secreted into the extracellular environment and can be transported from cell-to-cell, thereby affecting the physiological state of the neighboring cells in a prion-like manner...

Despite a growing body of evidence suggests that abnormal iron metabolism plays an important role in the pathogenesis of Parkinson's disease (PD), few studies explored its role in non-motor symptoms (NMS) of PD. The present study aimed to investigate the relationship between abnormal iron metabolism and NMS of PD. Seventy PD patients and 64 healthy controls were consecutively recruited to compare serum iron, ceruloplasmin, ferritin, and transferrin levels. We evaluated five classic NMS, including depression, anxiety, pain, sleep disorder, and autonomic dysfunction in PD patients using the Hamilton Depression Scale (HAMD), the Hamilton Anxiety Scale (HAMA), the short form of the McGill Pain Questionnaire, the Pittsburgh Sleep Quality Index and the Scale for Outcomes in Parkinson's disease for Autonomic Symptoms, respectively...

BACKGROUND: Non-motor symptoms in Parkinson's disease (PD), such as cognitive, emotional, autonomic and somatosensory alterations, are not ubiquitous but vary between the tremor dominant (TD) and postural instability/gait difficulty (PIGD) subtypes of the syndrome. Non-motor phenomena (e.g., anxiety, depression and apathy) have been related to representation of autonomic and somatosensory sensations (interoception), and recent findings suggest interoceptive deficits in PD. OBJECTIVES: To test whether interoceptive processing is differently affected in TD and PIGD phenotypes, by assessing both interoceptive accuracy and sensibility in PD patients with TD and PIGD subtypes, and in healthy controls...

Degeneration of noradrenergic locus coeruleus neurons occurs during the prodromal phase of Parkinson's disease and contributes to a variety of non-motor symptoms, e.g. depression, anxiety and REM sleep behavior disorder. This study was designed to establish the first locus coeruleus α-synucleinopathy mouse model, which should provide sufficient information about the time-course of noradrenergic neurodegeneration, replicate cardinal histopathological features of the human Parkinson's disease neuropathology and finally lead to robust histological markers, which are sufficient to assess the pathological changes in a quantitative and qualitative way...

Muscle weakness is a frequent complaint amongst Parkinson's disease (PD) patients. However, evidence-based therapeutic options for this symptom are limited. We objectively measure the efficacy of therapeutic Thai massage (TTM) on upper limb muscle strength, using an isokinetic dynamometer. A total of 60 PD patients with muscle weakness that is not related to their 'off' periods or other neurological causes were equally randomized to TTM intervention (n = 30), consisting of six TTM sessions over a 3-week period, or standard medical care (no intervention, n = 30)...

STUDY OBJECTIVES: Parkinson disease (PD) non-motor symptoms are associated with sleep disorders and impair quality of life. Our objective was to assess the effect of obstructive sleep apnea (OSA) treatment using continuous positive airway pressure (CPAP) on PD non-motor symptoms. METHODS: In this prospective observational study, 67 patients with idiopathic PD underwent polysomnography. Those with moderate-severe OSA were offered CPAP therapy. Subjects were divided into those without OSA (OSA-), and those with OSA (OSA+)...

INTRODUCTION: The diagnosis of Parkinson's disease (PD) is typically based on the presence of motor symptoms, but in the early phase of the disease, the diagnostic process can be challenging. Examination of non-motor symptoms in patients suspected of PD has gained growing attention. Olfactory tests have shown promising results as ancillary diagnostic tests. The aim of this study was to investigate how olfactory tests may be used clinically in diagnostic process in PD. METHODS: A systematic search was conducted in PubMed for relevant literature on 8 March 2017...

INTRODUCTION: Olfactory dysfunction has been established as a frequent non-motor symptom in neurodegenerative and movement disorders such as Parkinson's disease, Alzheimer's disease, and hereditary ataxias. To expand knowledge of non-motor symptoms in dystonia, and to test for a potential endophenotype, we examined olfactory function in cervical dystonia (CD). METHODS: In patients with CD, and neurologically healthy controls, olfactory function was examined by "Sniffin' Sticks", a test of nasal chemosensory function based on pen-like odor dispensing devices...

INTRODUCTION: Non-motor fluctuations (NMF) and motor fluctuations (MF) are frequent in patients with Parkinson's disease (PD) with long-term medical treatment. We aimed to examine the timing of the emergence of NMF with reference to MF in a prospective cohort of patients with PD without symptom fluctuations. METHODS: A total of 334 patients with PD who had neither MF nor NMF were recruited. The exclusion criteria included a Mini-Mental State Examination score of less than 26 points at baseline and an alternative diagnosis or significant comorbidity during follow-up...

Deep brain stimulation (DBS) is a surgical treatment in which stimulation electrodes are permanently implanted in basal ganglia to treat motor fluctuations and symptoms of Parkinson's disease (PD). Subthalamic nucleus (STN) and globus pallidus internus (GPi) are the commonly used targets for DBS in PD. Many studies have compared motor and non-motor outcomes of DBS in both targets. However, the selection of PD patients for DBS targets is still poorly studied. Therefore, we performed this narrative review to summarize published studies comparing STN DBS and GPi DBS...

INTRODUCTION: Previous studies exploring the association between apathy and cognitive deficits in Parkinson's disease (PD) employed scales and questionnaires for apathy, which did not control for the possible confounding effect of motor symptoms. Here we investigated the cognitive correlates of "pure apathy" by the Dimensional Apathy Scale, which allows us to assess apathy minimizing the influence of motor symptoms. METHODS: Consecutive PD outpatients referred to our centre were screened...
