Dopaminergic medications used in the treatment of patients with Parkinson's disease are associated with motor and non-motor behavioural side-effects, such as dyskinesias and impulse control disorders also known as behavioural addictions. Levodopa-induced dyskinesias occur in up to 80% of patients with Parkinson's after a few years of chronic treatment. Impulse control disorders, including gambling disorder, binge eating disorder, compulsive sexual behaviour, and compulsive shopping occur in about 17% of patients with Parkinson's disease on dopamine agonists...

Levodopa/carbidopa intestinal gel (LCIG) infusion is an effective escalating therapy in patients with Parkinson disease (PD) suffering from motor fluctuations and dyskinesia. Levodopa/carbidopa given continuously as infusion provides an optimized application of the most effective and best tolerable antiparkinsonian drug. It has been proven to have a superior motor effect compared with oral levodopa and to improve also non-motor symptoms. However, invasiveness, discomfort resulting from carrying an external device, and side effects associated with the way of administration limit its application in PD patients...

Parkinson's disease (PD) is a complex, chronic disease that many patients live with for many years. In this work we propose a mHealth approach based on a set of unobtrusive, simple-in-use, off-the-self, co-operative, mobile devices that will be used for motor and non-motor symptoms monitoring and evaluation, as well as for the detection of fluctuations along with their duration through a waking day. Ideally, a multidisciplinary and integrated care approach involving several professionals working together (neurologists, physiotherapists, psychologists and nutritionists) could provide a holistic management of the disease increasing the patient's independence and Quality of Life (QoL)...

Parkinson's disease is a chronic neurodegenerative disorder with the core motor features of resting tremor, bradykinesia, rigidity, and postural instability. Non-motor symptoms also occur, and include cognitive dysfunction, mood disorders, anosmia (loss of smell), and REM sleep disturbances. As the development of medications and other therapies for treatment of non-motor symptoms is ongoing, it is essential to have animal models that aid in understanding the neural changes underlying non-motor PD symptoms and serve as a testing ground for potential therapeutics...

OBJECTIVE: Nonmotor symptoms (NMSs) are common in Parkinson disease (PD), affecting patient's quality of life. The prevalence and domains of NMSs in untreated de novo PD remains unclear, especially comparing to normal aging. The objective was to determine NMSs in untreated de novo PD patients. PATIENTS AND METHODS: We performed a cross-sectional study to evaluate the frequency and severity of NMSs in untreated de novo PD patients (n=71) and age-matched normal controls (n=60) using the Non-Motor Symptoms Scale (NMSS)...

Parkinson's disease (PD) is a movement disorder and the second most common neurodegenerative disease worldwide in which nigrostriatal dopaminergic neurons within substantia nigra pars compacta (SNC) are lost, with clinical motor and non-motor symptoms including bradykinesia, resting tremor, rigidity, stooping posture and cognitive deficits. This study was undertaken to evaluate the neuroprotective potential of acetyl-l-carnitine (ALC) against unilateral striatal 6-hydroxydopamine (6-OHDA)-induced model of PD and to explore some involved mechanisms...

Depression is frequently encountered during Parkinson's disease (PD) as a non-motor feature, which has been reported to cause and exaggerate motor deficits and neurodegenerative events in experimental PD models. We studied the effect of chronic mild stress (CMS) (pre, post and pre & post) exposure mediated depression on motor and non-motor symptoms, oxidative stress, inflammation and brain derived neurotrophic factor (BDNF) levels and its related signalling molecules against the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine/probenecid (MPTP/p) induced neurotoxicity in mice...

BACKGROUND: Levodopa/carbidopa intestinal gel therapy (LCIG) can efficiently improve several motor and non-motor symptoms of advanced Parkinson's disease (PD). The recently developed Movement Disorder Society-sponsored Unified Parkinson's Disease Rating Scale (MDS-UPDRS) improved the original UPDRS making it a more robust tool to evaluate therapeutic changes. However, previous studies have not used the MDS-UPDRS and the Unified Dyskinesia Rating Scale (UDysRS) to assess the efficacy of LCIG...

MicroRNAs (miRNAs) are a class of small, non-coding RNAs that regulate gene expression at the post-transcriptional level. Recently, it was reported that miR-137, miR-124, and miR-184 were widely expressed in the central nervous system and were vital to neuronal regulation. In this study, we detected the circulating levels of miR-137, miR-124, and miR-184 in PD patients, and explored the potential role of miR-124, miR-137, and miR-184 in the diagnosis of PD. We further described the relationship between these miRNAs and PD with depression (PD-Dep)...

Thanks to the non-human primate (NHP), we have shown that the pharmacological disturbance of the anterior striatum or of external globus pallidus triggers a set of motivation and movement disorders, depending on the functional subterritory involved. One can, therefore, assume that the aberrant activity of the different subterritories of basal ganglia (BG) could lead to different behavioral disorders in neuropsychiatric disorders as Tourette's syndrome and Parkinson's disease. We are now addressing in the NHP the impact of modulating dopamine or serotonin within the BG on behavioral disorders...

INTRODUCTION: Changes in personality have been described in Parkinson's disease (PD), with suggestion that those with established disease tend to be risk averse with a disinclination for addictive behaviour. However, little is known about the earliest and prodromal stages. Personality and its relationship with addictive behaviours can help answer important questions about the mechanisms underlying PD and addiction. METHODS: 941 population-ascertained PD subjects within 3...

BACKGROUND: Gastrointestinal function has received increased interest in the context of Parkinson's disease (PD). Constipation is among the most frequent non-motor symptoms, but our understanding of the underlying pathology is limited. Subjective constipation correlates poorly with objective markers. OBJECTIVE: The aims were to evaluate colonic transit time and volume in PD and to correlate these measures with subjective symptoms and gastric emptying. METHODS: Thirty-two PD patients and 26 controls were included...

BACKGROUND: Gastrointestinal symptoms are one of the most common non-motor features of Parkinson's disease (PD). Recently, a report from Taiwan revealed that irritable bowel syndrome (IBS) may be associated with an increased risk of developing PD; however, the prevalence of IBS in PD patients has not been fully evaluated. Rome III criteria are widely assessed with a questionnaire to determine functional gastrointestinal disorders. OBJECTIVE: We assessed the prevalence of constipation and IBS in PD patients in our cohort using Rome III criteria...

This article summarises the noteworthy contribution of Professor Jellinger to the understanding of Parkinson's disease (PD) as a disease affecting multiple body- and neurotransmitter-systems. Phosphorylated alpha-synuclein and the formation of Lewy pathology as neuropathological hallmarks of PD seem to spread from the enteric nervous system and the olfactory bulb in a rostrocranial direction to the CNS. Subsequently, a progressive degeneration of the dopaminergic-nigrostriatal system and widespread extranigral pathology affecting different anatomical structures and neurotransmitters are induced causing the various non-motor and motor symptoms of PD...

Although non-motor symptoms (NMS) of Parkinson's disease (PD) are very common also in early stages of the disease, they are still under-recognized. Screening tools for non-motor symptoms, such as non-motor symptoms questionnaire (NMSQuest), help clinicians to recognize NMS and to evaluate if patients could require further assessment or specific treatments. To validate an adapted Italian version of NMSQuest and study its psychometric properties, Italian PD patients self-completed Italian NMSQuest, and then underwent a standard clinical evaluation including motor assessment (by Hoehn and Yahr staging, unified Parkinson's disease rating scale part III) and non-motor assessment (by Montreal cognitive assessment, Beck depression inventory, neuropsychiatric inventory, Epworth sleepiness scale, scale for outcomes in Parkinson's disease-Autonomic and movement disorder society-sponsored revision of the unified Parkinson's disease rating scale part I)...

Parkinson's disease (PD) affects 1-2 per 1000 of the population at any time. PD prevalence is increasing with age and PD affects 1% of the population above 60 years. The main neuropathological finding is α-synuclein-containing Lewy bodies and loss of dopaminergic neurons in the substantia nigra, manifesting as reduced facilitation of voluntary movements. With progression of PD, Lewy body pathology spreads to neocortical and cortical regions. PD is regarded as a movement disorder with three cardinal signs: tremor, rigidity and bradykinesia...

Parkinson's disease (PD) is a common neurodegenerative disorder that exhibits motor and non-motor symptoms, as well as pathological hallmarks, including dopaminergic (DA) neuron death and formation of α-synuclein (α-Syn) Lewy bodies. Cyclin-G-associated kinase (GAK), a PD susceptibility gene identified through genome-wide association studies (GWAS), is a ubiquitous serine/threonine kinase involved in clathrin uncoating, though its PD-related function remains elusive. Here, we implicate the Drosophila GAK homolog, auxilin (aux), in a broad spectrum of parkinsonian-like symptoms...

Beyond classical motor symptoms, motivational and affective deficits are frequently observed in Parkinson's disease (PD), dramatically impairing the quality of life of patients. Using bilateral 6-hydroxydopamine (6-OHDA) lesions of the substantia nigra pars compacta (SNc) in rats, we have been able to reproduce these neuropsychiatric/non-motor impairments. The present study describes how bilateral 6-OHDA SNc lesions affect the function of the main striatal dopaminergic (DA) receptor subtypes. Autoradiography was used to measure the levels of striatal DA receptors, and operant sucrose self-administration and neuropharmacological approaches were combined to investigate the causal implication of specific DA receptors subtypes in the motivational deficits induced by a dorsostriatal DA denervation...

Levodopa-induced dyskinesia (LID) is a disabling motor complication occurring in Parkinson's disease patients (PD) after long-term l-DOPA treatment. Although its etiology remains unclear, there is accumulating evidence that LID relies on an excessive dopamine receptor transmission, particularly at the downstream signaling of D1 receptors. We previously reported that the pharmacological blockade of 5-alpha reductase (5AR), the rate limiting enzyme in neurosteroids synthesis, rescued a number of behavioral aberrations induced by D1 receptor-selective and non-selective agonists, without inducing extrapyramidal symptoms...
