Filter by:A higher prevalence of Helicobacter pylori infection rate has been demonstrated among PD patients compared to controls. As H. pylori infection is known to interfere with levodopa absorption, we embarked on this is a study to understand the effects of Helicobacter pylori infection eradication among a selected Malaysian population with Parkinsons disease, in relation to levodopa effectiveness and motor improvements. The study hypotheses are: 1. H. pylori eradication improves L-dopa 'onset' time and prolongs the L-dopa 'on-time' duration. 2. PD patients with H. pylori infection show clinical improvement in motor disability and quality of life after eradication therapy of H. pylori, assessed using UPDRS-III / PDQ39 questionnaires.
Study to assess the safety and tolerability of three doses of PBF-509 (80 mg, 160 mg and 240 mg) after repeated (8 days) single daily oral dose administration in young male and female healthy subjects.
Sleep wake disturbance is a common problem in Parkinson's disease patients and so far the therapeutic possibilities for symptomatic relief are limited. Small, open-label studies indicate that the use of Xyrem (gamma-hydroxybutyrate) might be of benefit in this situation. This study is intended to show a beneficial effect of the study medication in a randomized cross-over trial, that fulfills strict scientific criteria.
It has been hypothesized, based on epidemiological observations, that Helicobacter pylori (HP) infection may play a role in the pathogenesis of Parkinson's Disease (PD). Previous studies have also shown that HP eradication therapy may result in improvements in levodopa pharmacokinetics and motor fluctuations. This study aims to examine the effects of HP eradication, using a double-blind randomized placebo-controlled trial design in a relatively large cohort of patients. Outcomes of interest include motor function, gastrointestinal symptoms and health-related quality of life. The investigators hypothesize that HP eradication will lead to improvements in motor function. The primary outcome of interest is the "ON"-medication Unified PD Rating Scale (UPDRS) Part III score at 3 months. Secondary outcomes include Purdue Pegboard Score, Timed Test of Gait, Dyskinesia and Bradykinesia scores measured by Parkinson's Kinetigraph (PKG), Leeds Dyspepsia Questionnaire (LDQ), Parkinson's Disease Questionnaire (PDQ-39), UPDRS Part I, Part II and Part IV; and Montreal Cognitive Assessment (MOCA).
This research will help us to understand whether transcranial direct current stimulation (tDCS) can safely improve recovery of speech and language abilities, gait , and mood in people with Parkinson's disease and related disorders. Some of the disorders that will be studied to understand if tDCS can be useful include Parkinson's Disease, Multi-System Atrophy (MSA) and progressive supranuclear palsy (PSP).
The goal of this study is to assess [18F]MNI-777 PET imaging as a tool to detect tau pathology in the brain of individuals who carry a clinical diagnosis of a tauopathy, including: Alzheimer's Disease (AD),Parkinson's disease (PD) Progressive Supranuclear Palsy (PSP), chronic traumatic encephalopathy (CTE) and Frontal Temporal Dementia (FTD) and age- and gender-matched healthy subjects.
Decreased muscle strength has been reported to be a factor contributing to increased incidences of falling in the elderly patients causing fractures, joint dislocations, severe soft tissue lesions and head trauma. Parkinson's Disease (PD) patients often complain of weakness and it has been reported that they have reduced muscle strength, decreased rate of force development, impaired ability to maintain constant force, and increased muscle coactivation during balance perturbation tasks. The specific cause of this weakness is not known, and in this study the investigators have analyzed and measured isokinetic muscle strength in PD patients to clarify this issue. The investigators have compared the data obtained with those of age-matched controls.
The purpose of this study is to assess the pharmacokinetics (PK) of BIA 9-1067 in patients with moderate chronic hepatic impairment and in matched healthy subjects.
Parkinson's disease is a degenerative disorder of the central nervous system. The motor symptoms of Parkinson's disease result from the death of dopamine-generating cells in the substantia nigra, a region of the midbrain; the cause of this cell death is unknown. Early in the course of the disease, the most obvious symptoms are movement-related; these include shaking, rigidity, slowness of movement and difficulty with walking and gait. A multidisciplinary intensive rehabilitation treatment (MIRT) is able to improve different parameters in PD that are poorly responsive to dopaminergic therapy. In this study, we aim to understand whether the passive mobilization of the metatarsophalangeal joint of the hallux determines an increase in the joint range in this district, allowing to improve, at least, the gait.
The aims of this study is to assess the efficacy of the crossover on balance in Parkinsonian patients and compare this results with the results of a control group of patients treated with a stabilometric platform.
