BACKGROUND: Both motor and non-motor symptoms could contribute to significant deterioration of psychological well-being in patients with Parkinson's disease (PD). However, its assessment has been only indirectly evaluated using tools based on health-related quality of life (HRQoL), such as the PDQ-39 scale. OBJECTIVES: To evaluate psychological well-being in PD using a specific tool of assessment, the Psychological Well-being Scale (PWS), and its clinical correlates...

REVIEW
Maximilian J Wessel, Friedhelm C Hummel
Non-invasive brain stimulation (NIBS) combined with behavioral training is a promising strategy to augment recovery after stroke. Current research efforts have been mainly focusing on primary motor cortex (M1) stimulation. However, the translation from proof-of-principle to clinical applications is not yet satisfactory. Possible reasons are the heterogeneous properties of stroke, generalization of the stimulation protocols, and hence the lack of patient stratification. One strategy to overcome these limitations could be the evaluation of alternative stimulation targets, like the cerebellum...

Appearance of L-DOPA-induced dyskinesia (LID) represents a major limitation in the pharmacological therapy with the dopamine precursor L-DOPA. Indeed, the vast majority of parkinsonian patients develop dyskinesia within 9-10 years of L-DOPA oral administration. This makes the discovery of new therapeutic strategies an important need. In the last decades, several animal models of Parkinson's disease (PD) have been developed, to both study mechanisms underlying PD pathology and treatment-induced side effects (i...

Background: Levodopa-carbidopa intestinal gel (LCIG; carbidopa-levodopa enteral suspension in the United States), delivered via percutaneous gastrojejunostomy (PEG-J) and titrated in the inpatient setting, is an established treatment option for advanced Parkinson's disease (PD) patients with motor fluctuations. However, long-term prospective data on the efficacy of LCIG on non-motor symptoms and the safety of outpatient titration are limited. Methods: In this 60-week, open-label phase 3b study, LCIG titration was initiated in an outpatient setting following PEG-J placement in PD patients...

NMSs have been extensively studied in PD patients but not in other forms of parkinsonism such as Progressive Supranuclear Palsy (PSP). The primary objective of this study was to analyze the frequency, severity and the type of non-motor symptoms (NMS) in PSP patients using the non-motor symptoms scale (NMSS). The secondary objective was to differentiate NMS between PSP and Parkinson's disease (PD). We enrolled in this cross-sectional study 50 consecutive PSP and 100 matched Parkinson's disease (PD) patients, in the proportion PSP/PD = 1/2, matched in age, sex, and disease duration...

Temporal discrimination is the ability to determine that two sequential sensory stimuli are separated in time. For any individual, the temporal discrimination threshold (TDT) is the minimum interval at which paired sequential stimuli are perceived as being asynchronous; this can be assessed, with high test-retest and inter-rater reliability, using a simple psychophysical test. Temporal discrimination is disordered in a number of basal ganglia diseases including adult-onset dystonia, of which the two most common phenotypes are cervical dystonia and blepharospasm...

Schizophrenia is a severe mental disorder that affects the anatomy and function of the brain, with an impact on one's thoughts, feelings, and behavior. The purpose of the study was to investigate cerebral blood flow (CBF) and brain connectivity in a group of patients with schizophrenia. Pseudo-continuous arterial spin labeling (pCASL) images were acquired from 28 patients in treatment and 28 age-matched healthy controls. Mean CBF and connectivity patterns were assessed. Schizophrenia patients had decreased CBF in the bilateral frontal pole and superior frontal gyrus, right medial frontal gyrus, triangular and opercular parts of the inferior frontal gyrus, posterior division of the left supramarginal gyrus, superior and inferior divisions of the left lateral occipital cortex, and bilateral occipital pole...

There have been an increasing number of reports of non-cognitive symptoms in Alzheimer's disease (AD). Some symptoms are associated with the loss of motor functions, e.g. gait disturbances, disturbed activity level and balance. Consistent with clinical findings, several AD mouse models harboring amyloid pathology develop motor impairment. Although the factors that contribute to the motor deficits have not yet been determined, it has been suggested that axonopathy is one of the key factors that may contribute to this particular feature of the disease...

Importance: Parkinson disease is a progressive neurologic disorder. Limited evidence suggests endurance exercise modifies disease severity, particularly high-intensity exercise. Objectives: To examine the feasibility and safety of high-intensity treadmill exercise in patients with de novo Parkinson disease who are not taking medication and whether the effect on motor symptoms warrants a phase 3 trial. Design, Setting, and Participants: The Study in Parkinson Disease of Exercise (SPARX) was a phase 2, multicenter randomized clinical trial with 3 groups and masked assessors...

OBJECTIVE: We evaluated neuropsychological tests to compare cognitive impairment between two types of multiple system atrophy: predominant parkinsonism (MSA-P) and predominant cerebellar ataxia (MSA-C). PATIENTS AND METHODS: This cross-sectional study included 14 patients diagnosed with MSA: four with MSA-C and ten with MSA-P. Presence of motor symptoms was determined by using the Unified Rating MSA Scale (URMSAS). Non-motor symptoms were evaluated by the Short Form Health Survey (SF-36), Scales for Outcomes in Parkinson's disease Autonomic (SCOPA-AUT), Hospital Anxiety and Depression Scale (HADS), and Beck Depression Inventory (BDI)...

Periodic limb movements (PLMs) during sleep increase with age and are associated with striatal neurodegeneration and dopamine deficiency. Limb movements are often associated with disruptions to non-rapid eye movement (NREM) sleep. Motor skill memory consolidation recruits the striatum, and learning-dependent striatal activation is associated with NREM sleep. Therefore, we investigated whether de novo individuals who significantly experience elevated levels of PLMs but have not been formally diagnosed with periodic limb movement disorder had learning and sleep-related memory deficits and whether these deficits were related to sleep quality and symptom severity...

Audrey S Dickey, Albert R La Spada
Huntington disease (HD) is a progressive autosomal dominant neurodegenerative disorder in which patients typically present with uncontrolled involuntary movements and subsequent cognitive decline. In 1993, a CAG trinucleotide repeat expansion in the coding region of the huntingtin (HTT) gene was identified as the cause of this disorder. This extended CAG repeat results in production of HTT protein with an expanded polyglutamine tract, leading to pathogenic HTT protein conformers that are resistant to protein turnover, culminating in cellular toxicity and neurodegeneration...

Growing evidence suggests, as Parkinson's disease (PD) progresses, that its non-motor symptoms appear prior to or in parallel with its motor deficits. Alpha-synuclein A53T transgenic mouse (A53T) is an essential tool to investigate the onsets and the extents of PD non-motor symptoms. Our aim is to investigate spatial learning and memory ability in A53T mice. In our rotarod tests, no motor coordination impairments were detected in mice of 3, 6, 9, and 12 months old. We then investigated their spatial learning and memory ability through Morris water maze in 3- and 9-month-old mice...

Parkinson's disease (PD) is a dopaminergic neurodegenerative disorder, which presents motor and non-motor symptoms.7-Fluoro-1,3-diphenylisoquinoline (FDPI) is an isoquinoline compound with antioxidant and antidepressant properties. This study investigated whether FDPI reverses motor and non-motor symptoms in an acute mouse model of PD induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). It was also assessed the anti-inflammatory mechanisms in FDPI pharmacological action. C57Bl/6 male adult mice received four MPTP (20mg/kg, intraperitoneal) or saline (vehicle) injections to induce an acute PD model...

In patients with Parkinson's disease (PD), management of non-motor symptoms, including cognitive and behavioural symptoms, is still a challenging need [1], which may be approached by various therapeutic strategies. A randomized controlled trial (RCT) in PD patients showed that a 13-week cognitive rehabilitation program training various cognitive functions (attention, memory, language, executive functions, social cognition) may improve cognition and functional disability [2]. Diez-Cirarda et al. [3] report the results obtained in 15 PD patients in early disease stages, as 18-month follow-up study of such RCT [2]...

Parkinson's disease (PD) patients are often characterized by copper dyshomeostasis, which is responsible for ROS formation and fibrillogenesis. However, the relationships between copper metabolism and PD development are unclear. In this study in 50 patients with PD (pPD) and 50 age-matched healthy individuals, the serum total copper concentration, oxidase activity, ceruloplasmin and SOD3 protein concentrations were measured; and amount of copper atoms per ceruloplasmin molecule was calculated. These parameters were lower in pPD relatively to healthy volunteers...

Ambulatory esophageal pH monitoring is an essential method in patients exhibiting signs of non-erosive reflux disease (NERD) to make an objective diagnosis. Intra-esophageal pH monitoring is important in patients who are non-responsive to medications and in those with extraesophageal symptoms, particularly in NERD, before surgical interventions. With the help of the wireless capsule pH monitoring, measurements can be made under more physiological conditions as well as longer recordings can be performed because the investigation can be better tolerated by patients...

Patients with Parkinson's disease experience disabling non-motor symptoms, including autonomic dysfunction, cognitive decline, and sleep disorders. Pharmacologic treatments for these symptoms are often ineffective or have intolerable side effects. Therefore, non-pharmacologic interventions are an attractive alternative. Exercise in particular has the potential to alleviate the progressive impairment related to these non-motor symptoms. In this commentary, we explore available research that addresses the impact of exercise and physical activity on autonomic dysfunction, cognitive impairment, and sleep disorders in Parkinson's disease and suggest areas in need of further study...
