BACKGROUND/OBJECTIVE: Very little is known about the association between glaucoma and Parkinson's disease in the elderly. The objective of this study was to determine whether glaucoma is associated with Parkinson's disease in older people in Taiwan. METHODS: A retrospective cohort study was conducted to analyze the Taiwan National Health Insurance Program database from 2000 to 2010. We included 4,330 subjects aged 65 years or older with newly diagnosed glaucoma as the glaucoma group, and 17,000 randomly selected subjects without a glaucoma diagnosis as the non-glaucoma group...

BACKGROUND: Visual Hallucinations (VH) are a common symptom experienced by individuals with Parkinson's disease (PD); however, a validated measure of VH has yet to be established for this population. The North-East Visual Hallucinations Interview (NEVHI), a promising VH measure, has not been well validated in PD. The aim of this study was to evaluate the convergent and discriminant validity of the NEVHI as well as the proportional identification and characteristics of VH in PD. METHODS: One hundred seventeen individuals with PD completed the NEVHI as well as evaluations of psychological, cognitive, motor, and visual functioning as measures of convergent and divergent validity...

Parkinson's disease (PD) is more commonly associated with its motor symptoms and the related degeneration of dopamine (DA) neurons. However, it is becoming increasingly clear that PD patients also display a wide range of non-motor symptoms, including memory deficits and disruptions of their sleep-wake cycles. These have a large impact on their quality of life, and often precede the onset of motor symptoms, but their etiology is poorly understood. The fruit fly Drosophila has already been successfully used to model PD, and has been used extensively to study relevant non-motor behaviours in other contexts, but little attention has yet been paid to modelling non-motor symptoms of PD in this genetically tractable organism...

OBJECTIVE: In the gastrointestinal neural system, the emergence of Lewy Body (LB) is usually earlier than the clinical diagnosis of Parkinson (PD) motor symptoms. Therefore, this study is aimed to explore whether the LB in the gastrointestinal tract of prodromal PD patients. PATIENTS AND METHODS: 98 paraffin embedded tissue specimens from 57 PD patients were collected in the Second Affiliated Hospital of Soochow University archives, as well as 98 tissue specimens of 90 non-PD patients undergone surgical resection...

Pain is a frequent but still neglected non-motor symptom of Parkinson's disease (PD). However, neural mechanisms underlying pain in PD are poorly understood. Here we explored whether the high prevalence of pain in PD might be related to dysfunctional descending pain control. Using fMRI we explored neural responses during the anticipation and processing of heat pain in 21 PD patients (Hoehn&Yahr I-III) and 23 healthy controls (HC). PD patients were naïve to dopaminergic medication in order to avoid confounding drug effects...

BACKGROUND AND PURPOSE: New venues are currently being explored to predict disease progression in Parkinson's disease (PD), such as non-motor subtypes and models merging motor and non-motor symptoms (NMS). By involving a subgroup of 585 patients from the PRIAMO (Parkinson Disease Non-motor Symptoms) study, the present 24-month longitudinal prospective analysis aimed to demonstrate that urinary dysfunction is an early marker of higher motor and non-motor burden as well as lower health-related quality of life...

An early and differential diagnosis of parkinsonian syndromes still remains a challenge mainly due to the similarity of their symptoms during the onset of the disease. Recently, (18)F-Desmethoxyfallypride (DMFP) has been suggested to increase the diagnostic precision as it is an effective radioligand that allows us to analyze post-synaptic dopamine D2/3 receptors. Nevertheless, the analysis of these data is still poorly covered and its use limited. In order to address this challenge, this paper shows a novel model to automatically distinguish idiopathic parkinsonism from non-idiopathic variants using DMFP data...

Parkinson's disease (PD) frequently entails non-motor symptoms, worsening the course of the disease. Apathy is one of the core neuropsychiatric symptoms that has been investigated in recent years; research is however hampered by the limited availability of well-evaluated apathy scales for these patients. We evaluated the psychometric properties of the Apathy Evaluation Scale (AES) in a sample of PD patients. Psychometric properties, convergent and discriminant validity and sensitivity/specificity were evaluated in patients with (n = 582) or without dementia/depression (n = 339)...

According to embodiment, the recruitment of the motor system is necessary to process language material expressing a motor content. Coherently, an impairment of the motor system should affect the capacity to process language items with a motor content. The aim of the present study was to assess the capacity to process graspable objects and their nouns in Parkinson's disease (PD) patients and healthy controls. Participants saw photos and nouns depicting graspable and non-graspable objects. Scrambled images and pseudo-words served as control stimuli...

BACKGROUND: Recent genetic and epidemiological studies have shown that there is a link between essential tremor and Parkinson's disease (PD). However, there is a lack of data about the clinical features of PD developed from essential tremor. OBJECTIVE: To explore and describe the clinical characteristics of Parkinson's disease developed from essential tremor (ET-PD). METHODS: Twenty-five ET-PD patients and 124 IPD controls were enrolled according to each criterion...

Identification of early changes in Dopamine-Transporter (DaT) SPECT imaging expected in the prodromal phase of Parkinson's disease (PD), are usually overlooked. Carriers of the G2019S LRRK2 mutation are known to be at high risk for developing PD, compared to non-carriers. In this work we aimed to study early changes in Dopamine uptake in non-manifesting PD carriers (NMC) of the G2019S LRRK2 mutation using quantitative DaT-SPECT analysis and to examine the potential for early prediction of PD. Eighty Ashkenazi-Jewish subjects were included in this study: eighteen patients with PD; thirty-one NMC and thirty-one non-manifesting non-carriers (NMNC)...

Intrajejunal levodopa infusion (IJLI) therapy is one of the most influential therapies in moderate to late stage Parkinson's disease with documented effects on motor and non-motor symptoms and quality of life. The process of initiation and maintenance of therapy however, remains a challenge particularly in the long term. Areas covered: The authors reviewed "evidence base" for pathways and advice given to patients pre and post IJLI initiation. The authors found lack of patient, carer and clinician led "real life" advisory documents which need to be given to patients on IJLI...

Phosphorylated α-synuclein (p-syn) in skin nerves mainly in the proximal sites is a promising neurodegenerative biomarker for idiopathic Parkinson disease (IPD). However, the p-syn spine distribution particularly in patients with unilateral motor dysfunctions remains undefined. This study aimed to investigate in IPD p-syn differences between left and right cervical spine sites in patients with prevalent unilateral motor symptoms, and cervical and thoracic spine sites in patients with bilateral motor symptoms...

Parkinson's disease (PD) is a progressive movement disorder with multiple non-motor symptoms. Although family genetic mutations only account for a small proportion of the cases, these mutations have provided several lines of evidence for the pathogenesis of PD, such as mitochondrial dysfunction, protein misfolding and aggregation, and the impaired autophagy-lysosome system. Recently, vesicle trafficking defect has emerged as a potential pathogenesis underlying this disease. Rab GTPases, serving as the core regulators of cellular membrane dynamics, may play an important role in the molecular pathway of PD through the complex interplay with numerous factors and PD-related genes...

BACKGROUND: Subthalamic nucleus deep brain stimulation (STN-DBS) is an effective treatment for the motor and non-motor signs of Parkinson's disease (PD), however, psychological disorders and social maladjustment have been reported in about one third of patients after STN-DBS. We propose here a perioperative psychoeducation programme to limit such social and familial disruption. METHODS: Nineteen PD patients and carers were included in a randomised single blind study...

Parkinson's disease (PD) is a common neurodegenerative disorder, characterized by motor impairment and a wide range of non-motor symptoms, including sleep disorders and cognitive and affective deficits. In this study, we used a mouse model of PD based on 6-hydroxydopamine (6-OHDA) to examine the effect of thioperamide, a histamine H3 receptor antagonist, on circadian activity, recognition memory and anxiety. A partial, bilateral 6-OHDA lesion of the striatum reduces motor activity during the active phase of the 24 h cycle...

Non-human primate (NHP) models of Parkinson disease show many similarities with the human disease. They are very useful to test novel pharmacotherapies as reviewed here. The various NHP models of this disease are described with their characteristics including the macaque, the marmoset, and the squirrel monkey models. Lesion-induced and genetic models are described. There is no drug to slow, delay, stop, or cure Parkinson disease; available treatments are symptomatic. The dopamine precursor, L-3,4-dihydroxyphenylalanine (L-Dopa) still remains the gold standard symptomatic treatment of Parkinson...

Diffusion tensor imaging (DTI) is a non-invasive magnetic resonance imaging technique that can be used to assess microstructural changes in a brain disease such as Parkinson's disease (PD). Fractional anisotropy (FA) is a commonly used parameter in DTI analysis, although properties of DTI/FA in analyzing brain modifications in PD have been poorly profiled. This study was thus designed to characterize the detailed time course of FA in the substantia nigra (SN). A rat model of PD was induced by microinfusion of 6-OHDA into the right medial forebrain bundle...

Chronic traumatic encephalopathy (CTE) is a neuropathologic diagnosis typically made in human brains with a history of repetitive traumatic brain injury (rTBI). It remains unknown whether CTE occurs exclusively after rTBI, or whether a single TBI (sTBI) can cause CTE. Similarly, it is unclear whether impact (eg, motor vehicle accidents) and non-impact (eg, blasts) types of energy transfer trigger divergent or common pathologies. While it is established that a history of rTBI increases the risk of multiple neurodegenerative diseases (eg, dementia, parkinsonism, and CTE), the possible pathophysiologic and molecular mechanisms underlying these risks have yet to be elucidated...

PURPOSE: Apathy is associated with motor symptoms in Parkinson's disease (PD); therefore, its evaluation could be influenced by motor disability. The Dimensional Apathy Scale (DAS) evaluates apathy excluding confounding effects of motor symptoms. The present study had three major aims: (a) to explore the psychometric properties of the DAS in non-demented PD patients; (b) to determine an optimal cut-off score of the DAS to identify apathetic PD patients; and (c) to determine a specific apathy profile in PD patients as compared to healthy controls (HC)...
