Active clinical trials for "Parkinson Disease"

Age related macular degeneration (ARMD) is a major and irreversible cause of blindness among the elderly. The sub-retinal space, located between the retinal pigmentary epithelium (RPE) and the external segments of the retinal photoreceptors, plays a crucial role in this pathology. A recent epidemiologic study in the US, has shown that Parkinson patients treated with L-DOPA, developed only later an ARMD when compared to the untreated patients. The L-Dopa is an endogenous ligand of the GPR43 receptor (G protein-coupled receptors), located on the RPE's cell's apical pole. This receptor, via several intracellular mechanisms, regulates the cell's exosomal and endosomal pathways: it would appear that the L-DOPA, by stimulating this receptor, decreases significantly the RPE's exosome release. The contents of the exosomes is still uncertain, however in addition to their signalization role, it seems they transport pro-inflammatory components, possibly helping the cellular recruitment due to the mononuclear phagocytic systems, particularly toxic for the photoreceptors. The aim of this study is to estimate the prevalence of ARMD in a sample of Parkinson's Patients followed at Fondation Ophtalmologique Adolphe de Rothschild and to compared it to the prevalence of ARMD of the general population. Furthermore the study aims to explore a possible causal link between L-DOPA treatment and ARMD.

The purpose of this study is to evaluate treatment of advanced Parkinson's Disease (PD) patients on levodopa-carbidopa intestinal gel (LCIG) monotherapy in a routine clinical setting.

An observational study to characterize and compare long-term clinical outcomes data collected remotely through periodic tele-visits, interactive smartphone app sessions, and web-based surveys in individuals with Parkinson's Disease (PD) who have completed the interventional phases of the STEADY-PD3 and SURE-PD3 clinical trials.

Parkinson's disease leads to loss of employment on average within less than 10 years of disease onset and has been found to be associated with an increased absence from work. This combined with hospitalisation; use of secondary health services; drug usage; and caregivers needing to give up work contributed to the costs associated with the conditions. It has been estimated that early support for working age newly diagnosed would cost the government about 1.5 million Euro in the UK but might lead to a potential cost saving of over half a billion over 5 years. The study will explore the impact of a Parkinson diagnosis on employment. The study will be survey based and will include demographic questions: age, age at diagnosis of PD, educational level, and Nationality; questions pertaining to employment type, history, and reasons for leaving if this happened; and also general health.

The goal of this study is to optimize pre-analytical cerebrospinal fluid (CSF) extracellular vesicle isolation protocols for increasing the detection of LRRK2 activity in human CSF

BACKGROUND: Non-Motor Symptoms (NMS) are frequent in patients with Idiopathic Parkinson's Disease (IPD). Clinical expressions, postulated pathophysiological mechanisms and responsiveness to antiparkinson medication represent differences between IPD and secondary Parkinsonism (SP). OBJECTIVES: To evaluate NMS expressions in IPD, SP and a control group. METHODS: Diagnosis of SP was supported by comorbidity, radiological findings, type of onset, onset rate and progression, exposures for neuroleptics, and responsiveness to pharmacological antiparkinson therapy. The participants were consecutively recruited at two outdoor patient clinics. The Well-Being Map™ for evaluation. These were completed by the participants at one point before visit. The controls consisted of non-Parkinsonian individuals, matched by age and gender.

Treatment resistant motor features, such as postural instability and freezing of gait are common in people with Parkinson's disease and major contributors to morbidity and mortality. This project will use sleep studies, quantitative motor assessments and magnetic resonance imaging to examine the relationship between abnormally increased muscle activity during rapid eye movement sleep and the development and progression of treatment-resistant postural instability and gait disturbances. Specifically, the investigators will test the hypothesis that anticipatory postural adjustments (weight and pressure shifts) during gait initiation are significantly reduced in people with Parkinson's disease who have abnormally elevated muscle activity during rapid eye movement (REM) sleep compared to individuals will Parkinson's disease whose REM sleep muscle activity is normal. In addition, the investigators will test the hypothesis that the level of RSWA at baseline is predictive of measures of motor decline (postural stability and gait) and alterations in the structure and function of locomotor brainstem networks. Since sleep disorders can emerge years before a diagnosis of Parkinson's disease, establishment of a link between sleep and treatment-resistant posture and gait disorders will help identify individuals at risk of developing these disabling motor features of disease.

Vascular parkinsonism (VP) is defined as the presence of parkinsonian syndrome, evidence of cerebrovascular disease by brain imaging and an established relationship between the two disorders. However, the diagnosis of VP is problematic. This study aims to distinguish VP from Parkinson's disease (PD) in multiple aspects including clinical features as motor ,non motor symptoms ,response to treatment ,cognitive assessments by using multiple scales, neuro-radiological features of magnetic resonance imaging (MRI) and transcranial color-coded duplex (TCCD) findings. This differentiation will have therapeutic and prognostic implications .

This is an observational study to describe the treatment patterns and clinical outcomes observed with use of ONGENTYS as adjunctive treatment to levodopa/carbidopa in Parkinson's disease patients experiencing "off" episodes with motor fluctuations

Being the most important stakeholder of such a vulnerable population, the neuro physiotherapist faced a lot of difficulties while consulting and assessing patients with neurological impairments. Up to our knowledge and search history, this is the first-ever study conducted by us which list out the challenges faced by neuro physiotherapist while teleconsultation mode among Indian population.
