Parkinson's disease (PD) is a complex motor and non-motor disorder and management is often challenging. In this review, we explore emerging approaches to improve the care of patients, drawing from the literature regarding patient-centred care, patient and caregiver perspectives and priorities, gaps in knowledge among patients and caregivers and the need for accurate information, individual variability in disease manifestations, prognostication of disease course, new developments in health technologies and personalized medicine, specialty care, pharmacological and non-pharmacological management, financial burden, lifestyle and work-related issues, support groups and palliative care...

BACKGROUND AND PURPOSE: The presentation of Parkinson's disease patients with mutations in the LRRK2 gene (PDLRRK2 ) is highly variable, suggesting a strong influence of modifying factors. In this context, inflammation is a potential candidate inducing clinical subtypes. METHODS: An extensive battery of peripheral inflammatory markers was measured in human serum in a multicentre cohort of 142 PDLRRK2 patients from the MJFF LRRK2 Consortium, stratified by three different subtypes as recently proposed for idiopathic Parkinson's disease: diffuse/malignant, intermediate and mainly pure motor...

Hypokinetic dysarthria (HD) occurs in 90% of Parkinson's disease (PD) patients. It manifests specifically in the areas of articulation, phonation, prosody, speech fluency, and faciokinesis. We aimed to systematically review papers on HD in PD with a special focus on (1) early PD diagnosis and monitoring of the disease progression using acoustic voice and speech analysis, and (2) functional imaging studies exploring neural correlates of HD in PD, and (3) clinical studies using acoustic analysis to evaluate effects of dopaminergic medication and brain stimulation...

BACKGROUND: Pramipexole (PPX), a non-ergot dopamine receptor agonist, is a first-line treatment for Parkinson's disease (PD). A critical dose level above which a better benefit-to-harm ratio exists has not been examined. METHODS: Chinese PD patients (n=464) were retrospectively analyzed by PPX maintenance dose, PD stage, combined levodopa dose, and baseline tremor contribution. The sum score of Baseline Activities of Daily Living (part II) and Motor Examination (III) of the Unified Parkinson's Disease Rating Scale (UPDRS II+III) was used as a covariate for final score adjustment...

OBJECTIVE: Constipation is a common non-motor symptom of Parkinson's disease (PD). Although pathology of the enteric nervous system (ENS) has been associated with constipation in PD, the contribution of catecholaminergic neurodegeneration to this symptom is currently debated. The goal of this study was to assess the effects of the neurotoxin 6-hydroxydopamine (6-OHDA) on the colonic myenteric plexus and shed light on the role of catecholaminergic innervation in gastrointestinal (GI) function...

BACKGROUND: Bilateral deep brain stimulation of the subthalamic nucleus (STN-DBS) has considerable influence on motor and non-motor symptoms in Parkinson's disease (PD). While improvements in motor functioning can be easily assessed with general quality of life questionnaires, the measurement of specific STN-DBS-associated impairments often remains insufficient. Hence, we aimed to develop a questionnaire that measures STN-DBS-related impairments. METHODS: The development of the (STN-)DBS Impairment Scale (DBS-IS) consisted of four steps...

Parkinson's disease (PD) is an insidious onset neurodegenerative disease affecting approximately 1% of the population over the age of 65. So far available therapies for PD have only aimed at improving or alleviating symptoms, but not at slowing, preventing, and reversing the course of PD. Recently, some studies have indicated that the levels and activation of Abelson non-receptor tyrosine kinase (c-Abl, Abl1) were up-regulated in the brain tissue of patients with PD and demonstrated that c-Abl inhibitors could improve motor behavior, prevent the loss of dopamine neurons, inhibit phosphorylation of Cdk5, regulate α-synuclein phosphorylation and clearance, inhibit the tyrosine phosphorylation of parkin and decrease parkin substrate, for example, PARIS (zinc finger protein 746), AIMP2 (aminoacyl-tRNA synthetase-interacting multifunctional protein type2), FBP1 (fuse-binding protein 1), and synphilin-1...

Neuropsychiatric symptoms are common in Parkinson's disease (PD) and have a disproportionate impact on quality of life and carer burden. Pharmacological treatment is the main approach in dealing with these symptoms, but it is limited by variable efficacy and risk of drug interactions. Non-pharmacological approaches using the cognitive-behavioural therapy (CBT) model are viable alternatives and in this review paper we summarise the evidence of CBT for three of the most common psychiatric manifestations of PD: depression and anxiety, impulse-control disorders and insomnia...

BACKGROUND: Parkinson's Disease is a progressive neurodegenerative disease, characterized by symptoms of motor impairment, resulting from the loss of dopaminergic neurons in the midbrain, however non-neuronal symptoms are also common. Although great advances have been made in the pathogenic understanding of Parkinson's Disease in the nervous system, little is known about the molecular alterations occurring in other non-neuronal organ systems. In addition, a higher rate of melanoma and non-melanoma skin cancer has been observed in the Parkinson's Disease population, indicating crosstalk between these diseases...

Protein aggregation is a hallmark of the major neurodegenerative diseases including Alzheimer's, Parkinson's, Huntington's and motor neuron and is a symptom of a breakdown in the management of proteome foldedness. Indeed, it is remarkable that under normal conditions cells can keep their proteome in a highly crowded and confined space without uncontrollable aggregation. Proteins pose a particular challenge relative to other classes of biomolecules because upon synthesis they must typically follow a complex folding pathway to reach their functional conformation (native state)...

BACKGROUND: Depression is common in Parkinson's disease (PD) and adversely affects quality of life. Both unilateral and bilateral subthalamic (STN) deep brain stimulation (DBS) effectively treat the motor symptoms of PD, but questions remain regarding the impact of unilateral STN DBS on non-motor symptoms, such as depression. METHODS: We report changes in depression, as measured by the Hamilton Depression Rating Scale (HAMD-17), in 50 consecutive PD patients who underwent unilateral STN DBS...

In Parkinson's disease, motor signs have long been the main targets of the management of the disease. In recent years, non-motor disorders have elicited increasing interest. These disorders are under diagnosed and managed more difficultly than motor signs and are sometimes perceived as more disturbing by the patients. These signs are polymorphous, sometimes occurring before the motor symptoms but increase with the disease duration and complicating always the late stages. They may fluctuate as the motor signs, while being under the control of dopaminergic pathways, or be linked to the degeneration of other neuronal circuits...

Psychosis is one of the debilitating non-motor symptoms (NMS) of Parkinson's disease (PD). Cognitive impairment is considered to be a risk factor for emergence of psychosis in PD. Early detection of relevant cognitive impairment may serve as a predictor for development of psychosis, with implications for prevention and early intervention. However, the exact pattern of cognitive impairment associated with psychosis is not clear. In this article, we aim to critically review the literature on case-control studies in PD patients with and without psychosis in order to understand the pattern of cognitive impairment in those with psychosis...

Since the official and systematic inclusion of sex and gender in biomedical research, gender differences have been acknowledged as important determinants of both the susceptibility to develop neurodegenerative diseases in general population and the clinical and therapeutic management of neurodegenerative patients. In this review, we gathered the available evidence on gender differences in Parkinson's disease (PD) regarding clinical phenotype (including motor and non-motor symptoms), biomarkers, genetics and therapeutic management (including pharmacological and surgical treatment)...

Parkinson's disease (PD) is a slow progressive neurodegenerative disease associated with abnormal function of extrapyramidal system. Although several biochemical and genetic defects have been identified, increased oxidative stress and chronic inflammation are one of the earliest events that initiate and promote PD. Oxidative stress also participates in impaired non-motor symptoms.The levels of microRNAs that are evolutionarily conserved single-stranded non-coding RNAs of approximately 22 nucleotide in length are altered in PD...

Parkinson's disease, a progressive neuro-degeneration of multiple systems damaging motor and non-motor functions, affects individual and societal dimensions negatively. In addition to standard treatments, complementary and alternative medicine has been adopted, in which acupuncture, a traditional Chinese medical practice by needle penetration at specific stimulation points (acupoints) along the body, indicates positive outcomes in this illness. Apart from offering an overview of using acupuncture in Parkinson's disease, this literature review analyses the effects of acupuncture on Parkinson's-induced physical symptoms and mental problems such as slow movements, stiffness, constipation, and sleep disorders...

Why do we make hasty decisions for short-term gain? Rapid decision-making with limited accumulation of evidence and delay discounting are forms of decisional impulsivity. The subthalamic nucleus is implicated in inhibitory function but its role in decisional impulsivity is less well-understood. Here we assess decisional impulsivity in subjects with obsessive compulsive disorder who have undergone deep brain stimulation of the limbic and associative subthalamic nucleus. We show that stimulation of the subthalamic nucleus is causally implicated in increasing decisional impulsivity with less accumulation of evidence during probabilistic uncertainty and in enhancing delay discounting...

Diagnosis of Parkinson's disease (PD) is often traumatic. It is then important to organize this announcement in order to support the patient in this major step of his care course. Anxiety and depression are present in about 50% of PD patients. Besides pharmacological treatment, cognitive-behavioral therapy induces improvement in anxio-depressive symptoms. We have to promote physical activity for PD patients, from the beginning of the disease, because it prevents from deconditioning, improves motor and non-motor symptoms, quality of life, and decreases loneliness...

BACKGROUND: Over the years, a number of distinct treatments have been adopted for the management of the motor symptoms of Parkinson's disease (PD), including pharmacologic therapies and deep brain stimulation (DBS). Efficacy is most often evaluated by subjective assessments, which are prone to error and dependent on the experience of the examiner. Our goal was to identify an objective means of assessing response to therapy. METHODS: In this study, we employed objective analyses in order to visualize and identify differences between three groups: healthy control (N = 10), subjects with PD treated with DBS (N = 12), and subjects with PD treated with levodopa (N = 16)...

The presence of mutations in glucocerebrosidase (GBA) gene is a known factor increasing the risk of developing Parkinson's disease (PD). Mutations carriers have earlier disease onset and are more likely to develop neuropsychiatric symptoms than other sporadic PD cases. These symptoms have primarily been observed in Parkinson's patients carrying the most common pathogenic mutations L444P and N370S. However, recent findings suggest that other variants across the gene may have a different impact on the phenotype as well as on the disease progression...
