Parkinson's disease is the second most common neurodegenerative illness after Alzheimer's disease. In its advanced stages, it is characterized by various special symptoms. In addition to non-motor signs, motor complications are most prominent and most often can only be inadequately improved with pulsatile oral therapies. However, with the aid of continuous dopaminergic stimulation, improvements can be achieved even in advanced stages of the disease. This will not only alleviate motor and non-motor symptoms, but will also lead to a better quality of life...

Non-motor symptoms of Parkinson's disease have a significant impact on quality of life. Despite this, many non-motor symptoms remain unreported by patients and consequently untreated. This study explored barriers to help-seeking using two theoretical frameworks, the Common Sense Model of illness perception and Theoretical Domains Framework. A total of 20 participants completed semi-structured interviews to explore symptom beliefs and help-seeking behaviour. Uncertainty about the relationship of non-motor symptoms to Parkinson's disease and lack of clarity around treatments were common...

About 60 % of all patients with Parkinson's disease (PD) and about 50 % of PD patients with deep brain stimulation (DBS) in possession of a driving license are active car-drivers. Parkinson patients, however, often display physical and/or psychological weaknesses that can lead to loss of or reduced driving ability. Driving capability can also be affected by Parkinson medication. The attending physician is therefore obliged to advise his patients regarding their ability to be in command of a vehicle. This however can prove difficult in practice...

The gut with its variety of microbiota may serve as an etiological origin of diseases. Gut microbes may also play a role in the pathogenesis of diseases beyond their simple nutritional maintenance and support. For example, gut protein aggregation, possibly aided by microbes as well as nasal influences, might be linked to disease that may move to the brain through the vagus nerve. To this end, Braak has offered a "dual-hit" hypothesis that proposes a novel etiology for Parkinson's disease (PD). The hypothesis places the initial origin of the disease in the nose and the gastrointestinal tract (GI) after infection by an unknown pathogen that could aggregate in the gut and then eventually spread to the brain via the autonomic plexuses...

Deficits in the integration of motor prediction and its feedback have been reported in Parkinson's disease. Conscious awareness of action is proposed to emerge under the integration of motor prediction and its feedback. Thus, it may lead to changes in the awareness of the authorship of action (in other words, the sense of agency) in Parkinson's disease. We have employed both explicit and implicit measures to assess the awareness of action in Parkinson's disease and matched controls. As an explicit measure, an action recognition task requiring explicit judgments was used...

Parkinson's disease (PD) is a multisystem neurodegenerative disorder affecting, besides the dopaminergic function, multiple neurotransmission systems, including the cholinergic system. Central cholinergic circuits of human brain can be tested non-invasively by coupling peripheral nerve stimulation with transcranial magnetic stimulation (TMS) of motor cortex; this test is named short latency afferent inhibition (SAI). SAI abnormalities have been reported in PD patients with gait disturbances and many non-motor symptoms, such as visual hallucinations (VHs), REM sleep behavior disorder (RBD), dysphagia, and olfactory impairment...

BACKGROUND: Ethnic variations have been described in medical conditions, such as hypertension, diabetes, and multiple sclerosis. Whether ethnicity plays a role in Parkinson's disease (PD), particularly with regard to non-motor symptoms (NMS), remains unclear. Existing literature is diverse, controversial, and inadequately documented. This review aims to analyse and report the currently available literature on NMS, specifically in Asian PD patients. SUMMARY: We conducted a literature review using PubMed, searching for articles and currently available publications that reference and assess NMS in PD patients living in Asia using the validated NMS Questionnaire (NMS Quest) and NMS Scale (NMSS)...

INTRODUCTION: Parkinson's disease (PD) is characterized by a wide spectrum of non-motor symptoms that may impact negatively on the activities of the patient's daily life and reduce Health-related quality of life (HRQoL). The present study explored the impact of specific non-motor symptoms on the HRQoL in PD. METHODS: Eighty-four outpatients underwent the Montreal Cognitive Assessment (MoCA) assessing global functioning and several questionnaires to assess depression, apathy, impulse control disorders (ICD), anxiety, anhedonia and functional impact of cognitive impairment...

In this study, we conducted a clinical analysis of lymphocyte subtypes in 268 patients with Parkinson's disease (PD) to assess their clinical impact as a potential marker of advanced PD in Chinese patients. The participants comprised 268 sporadic PD patients and 268 healthy controls. The numbers of natural killer (NK) cells and CD3+, CD3+CD4+, CD3+CD8+, and CD19+ lymphocytes from peripheral blood were determined by immunostaining and flow cytometric analysis and the percentages of these CD+ T cells were calculated...

Speech impairment is a frequent and often serious symptom of Parkinson's disease (PD), characterized by a disorder of phonation, articulation and prosody. While research on the pathogenesis of the prominent limb motor symptoms has made considerable progress in recent years, the pathophysiology of PD speech impairment is still incompletely understood. To investigate the neural correlates of speech production in PD, EEG was recorded in 14 non-demented patients with idiopathic PD and preserved verbal fluency on regular dopaminergic medication (8 women; mean age ± SD: 69...

Mammalian physiology and behavior are regulated by an internal time-keeping system, referred to as circadian rhythm. The circadian timing system has a hierarchical organization composed of the master clock in the suprachiasmatic nucleus (SCN) and local clocks in extra-SCN brain regions and peripheral organs. The circadian clock molecular mechanism involves a network of transcription-translation feedback loops. In addition to the clinical association between circadian rhythm disruption and mood disorders, recent studies have suggested a molecular link between mood regulation and circadian rhythm...

BACKGROUND: Recent evidence suggests that glucosidase beta acid (GBA) mutations predispose Parkinson's disease (PD) patients to a greater burden of cognitive impairment and non-motor symptoms. This emerging knowledge has not yet been considered in patients who have undergone deep brain stimulation (DBS); a surgery that is generally contraindicated in those with cognitive deficits. OBJECTIVE: To explore the long-term phenotypic progression of GBA-associated PD, in a DBS cohort...

Rapid eye movement sleep behavior disorder (RBD) is one of the most common non-motor symptoms of parkinsonism, and it may serve as a prodromal marker of neurodegenerative disease. The mechanism underlying RBD is unclear. Several prospective studies have reported that specific non-motor symptoms predict a conversion risk of developing a neurodegenerative disease, including olfactory dysfunction, abnormal color vision, autonomic dysfunction, excessive daytime sleepiness, depression, and cognitive impairment. Parkinson's disease (PD) with RBD exhibits clinical heterogeneity with respect to motor and non-motor symptoms compared with PD without RBD...

The impact of neuroinflammation and microglial activation to Parkinson's disease (PD) progression is still debated. Post-mortem analysis of PD brains has shown that neuroinflammation and microgliosis are key features of end-stage disease. However, microglia neuroimaging studies and evaluation of cerebrospinal fluid (CSF) cytokines in PD patients at earlier stages do not support the occurrence of a pronounced neuroinflammatory process. PD animal models recapitulating the motor and non-motor features of the disease, and the slow and progressive neuropathology, can be of great advantage in understanding whether and how neuroinflammation associates with the onset of symptoms and neuronal loss...

BACKGROUND: Symptoms from the gastrointestinal tract are highly prevalent in Parkinson's disease (PD), but knowledge of the underlying pathology is incomplete and valid objective markers on regional gastrointestinal function are limited. OBJECTIVE: The aims were to evaluate gastrointestinal transit time and motility in PD patients and controls. METHODS: Twenty-two PD patients and 15 controls were included. Gastric-, small intestinal-, and caecum-ascending colonic transit times as well as colonic motility, defined as mass- and fast movements, were performed using the ambulatory 3D-Transit system...

Psychotic symptoms are common, disabling non-motor features of Parkinson's disease (PD). Despite noted heterogeneity in clinical features, natural history and therapy response, current dogma posits that psychosis generally progresses in a stereotypic manner through a cascade of events that begins with minor hallucinations and evolves to severe hallucinations and delusions. Further, the occurrence of psychotic symptoms is believed to indicate a poor prognosis. Here we propose a classification scheme that outlines the pathogenesis of psychosis as it relates to dysfunction of several neurotransmitter systems...

Many clinical studies have reported on the benefits of exercise therapy in patients with Parkinson's disease (PD). Exercise cannot stop the progression of PD or facilitate the recovery of dopamine (DA) neurons in the substantia nigra pars compacta (SNpc) (Bega et al., 2014). To tease apart this paradox, we utilized a progressive MPTP (1-methyl-4-phenyl-1,2,3,6-tetra-hydropyridine) mouse model in which we initiated 4weeks of treadmill exercise after the completion of toxin administration (i.e., restoration)...
