Filter by:The purpose of the current study is to compare the impacts of specifically designed power training and strength training programs on function and physical performance in Parkinson's patients. Specific aims are to examine the impact of these interventions on performance variables such as balance, strength, power, posture, gait and physical function.
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.
The purpose of the study is to compare the effectiveness and specificity of agility and cycling exercise training on balance and mobility outcomes in PD and age and gender matched healthy controls. The hypothesis is that due to being profoundly deconditioned, agility and cycling will be similarly effective in PD but agility will be more effective then cycling in healthy old adults, in improving mobility and balance.
Parkinson's disease (PD) is a progressive neurological disorder that is increasingly common with age, with the incidence rising from approximately 4 people per 10,000 in their forties to 2 in 100 over the age of eighty. Our understanding of the causes of PD has rapidly developed in the past two decades, but this has not yet translated into any clinically established neuroprotective treatment that slows disease progression. There is a growing consensus that the failure of previous efforts is mainly due to the causative diversity of PD i.e. that PD may have many different causes. For example, it is known that variants in mitochondrial (cellular power house) genes can cause specific forms of PD and this may be relevant to other forms of PD. The aim of this study is to attempt to group PD patients based on markers of biochemical dysfunction (e.g. into groups of patients that do and those who do not have evidence of mitochondrial dysfunction) to aid in the development of new candidate neuro-protective compounds. The investigators hope by grouping people with Parkinson's into those with and without impaired mitochondrial function the investigators will be better able to develop more targeted treatments aimed at protecting further loss of brain cells that occurs in Parkinson's disease. To achieve this the investigators will study people, in two study sites in London, with both genetic forms of PD and those with idiopathic PD (i.e. those where there is not a known genetic variant causing PD), as well as a healthy control group. All groups will undergo standardised clinical assessment to collect information on several aspects of their condition (e.g. disease severity, memory problems and sleep problems). Participants will be asked to provide blood, urine and optionally cerebrospinal fluid & skin samples from which various biochemical assays and genetic analysis will be performed in attempt to group participants based on the results of these tests. The study is funded for 3 years with participants being asked to attend for up to 3 study visits each over this time period.
In patients with Parkinson's disease, the characteristic motor symptoms, i.e., slowness of movement (bradykinesia), tremor and rigidity, are consequences of the progressive degeneration of neurons containing and releasing dopamine. The first-line treatment of Parkinson´s is oral administration of levodopa - a precursor to dopamine that (unlike dopamine) passes the blood brain barrier. After the first few years of treatment with levodopa, many patients do however develop a highly variable response to the drug characterised by rapid shifts between impaired locomotion and drug induced dyskinesias (referred to as the on-off syndrome). This is cased by the marked variation in serum levodopa levels following per oral administration, and it is known that intravenous administration of levodopa give a more stable level of levodopa with improved on-off symptoms. Levodopa-carbidopa intestinal gel (LCIG) - under the name of Duodopa® - is delivered directly to the proximal jejunum via a tube connected to a portable infusion pump. Infusion of Duodopa in the jejunum bypasses gastric emptying, helping to avoid the fluctuation in plasma levodopa levels. However, while clearly confirming that an even administration of levodopa is of considerable benefit to Parkinson patients with on-off symptomatology, the LCIG approach is marred by the need for surgery (for the insertion of the intestinal tube) and various possible complications following this, as well as by side effects such as abdominal pain. Researchers have now succeeded in producing a physiologically acceptable levodopa solution (called Infudopa) in a concentration allowing for a continuous intravenous (i.v.) or subcutaneous (s.c.) administration of therapeutic doses to humans. Early experience of this strategy confirms that both s.c. and i.v. administration of this solution results in even serum levodopa levels and markedly improved motor functioning. The aim of this study is to compare the pharmacokinetic profile of Infudopa administered i.v. and s.c. with that of Duodopa administered enterally in parkinsonian patients with on-off complications.
The aim of this investigation is to explore the effect of reducing conventional pulse width of stimulation on known adverse effects of Subthalamic nucleus Deep Brain Stimulation (STN DBS) treatment such as; slurring of speech, gait impairment, and unsteadiness. This investigation is designed such that each of 16 patients (who have all had chronically implanted DBS systems), will be assessed using conventional (DBS-60µs) and short (DBS-30µs) pulse width DBS, in a randomised order.
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 freezing of gait (FOG) is one of the disabling symptoms in Parkinson's disease. The diagnosis and assessment of the FOG may be diffucult, but it is absolutely necessary. The aim of this study was to develop a Türkish version of the freezing of gait questionnaire (FOG-Q) and assess the validity and reliability of this Türkish version. The researchers firstly communicated with the developers of the FOG-Q. The permission for Turkish version was received by Giladi. Then, the FOG-Q will be adapted into Türkish using forward-backward translation by three native Türkish-speaking forward translators and one native English-speaking backward translator. The internal reliability of the FOG-Q Türkish version will be assessed using Cronbach's alpha, and item analyses will be conducted by examining the effect on Cronbach's alpha of excluding each of the six FOG-Q items individually. The test-retest reliability will be assessed using intraclass correlation coefficient (ICC). Convergent validity will be evaluated by means of Spearman rank correlation coefficient (rs). In this section will be determined the correlation between the FOG-Q scores and scores of the UPDRS motor section , Berg Balance Scale, Timed up and go test, Falls Efficacy Scale and Hoehn and Yahr stages.
This study occurs during five visits that are already scheduled as part of "Biomarkers to Guide Directional DBS for Parkinson's Disease" (ClinicalTrials.gov Identifier: NCT03353688). If participants have dystonia associated with Parkinson's disease, the investigators will consent and administer one additional rating scale (Burke-Fahn-Marsden Dystonia Rating Scale) to assess the severity of dystonia.
The purpose of this clinical trial conducted in patients with Parkinson's Disease is to study the relationship between patient individual profile and their response to IPT803 Adjunct Treatment (treatment response being characterized by movements improvement).
