Filter by:Background: The autonomic nervous system controls automatic body functions. Researchers want to improve the tests used to diagnose autonomic failure. Orthostatic hypertension is a drop in blood pressure when a person stands up. Researchers want to focus on this sign of autonomic failure. Objective: To improve testing for conditions that cause autonomic nervous system failure. Eligibility: People ages 18 and older in one of these categories: - Their blood pressure drops when they get up. - They have had a heart transplant or bilateral endoscopic thoracic sympathectomies or have had or will have renal sympathetic ablation Design: All participants will be screened with: - Medical history - Physical exam - Blood and urine tests Some participants will be screened with: - Heart and breathing tests - IV placement into an arm vein - Tilt table testing: Participants lie on a table that tilts while an IV is used to draw their blood. Participants may stay in the hospital for up to 1 week depending on their tests. Tests may include repeats of screening tests and: - Sweat testing: A drug is placed on the skin to cause sweating. Sensors on the skin measure moisture. - Lumbar puncture: A needle is inserted between the bones in the back to collect fluid. - MRI and PET/CT scan: Participants lie on a table that slides into a scanner. For the PET/CT, a small amount of a radioactive chemical will be injected with a small amount of a radioactive chemical. - Bladder catheter placement to collect urine - Skin biopsies: A punch tool removes a small skin sample. - Tests to see how the pupils react to light - Smelling tests - Thinking and memory tests - Questionnaires Participants may have a visit about 2 years later to repeat tests.
Pain (spontaneous pain) is a fundamental non-motor symptom (NMS) of Parkinson's disease (PD) that is prevalent throughout the condition and often unrecognized and undertreated. The study of the scalp laser-evoked potentials (LEPs) (evoked pain) allows a non-invasive exploration of pain central pathways in humans. This technique proved useful in elucidating the physiopathology underlying different pain syndromes. This study has been conceived to study spontaneous pain (and/or evoked pain by laser stimulation) in PD patients (with or without pain) with motor fluctuations under drugs-on (Safinamide Metansolfonato or Rasagilina Mesilato).
Previous studies revealed changes in the pattern of cortical electrical activity of patients with Parkinson's disease (PD) and suggested that these changes may be dependent on the phenotypes of the disease and other related factors. A greater understanding of cortical electrical activity in PD patients may be relevant to guide professionals about the therapeutic use of repetitive transcranial magnetic stimulation (rTMS). The present study aims to evaluate the pattern of brain activity of PD patients and to correlate the findings with the disease phenotypes and with other clinical characteristics. For this, volunteers with PD and healthy will participate in a single experimental session in which behavioral and electrophysiological assessments will be performed.
Full Title: A phase II, randomized, open-label, double-blind, two-center study to evaluate the tolerability, safety and dose-finding of oil cannabis preparation for pain in Parkinson's disease. Short title: Cannabis oil for pain in Parkinson's disease Sample Size: N = 15 Study Population: Patients with Parkinson's disease and pain, without cognitive impairment. Study Duration: July 2018 - July 2019 Study Agent/ Intervention: Cannabis oil: mixed oil cannabis preparation consisting of 3 different formulations of ∆-9THC and cannabidiol - 18:0; 10:10; and 1:20 respectively. Cannabis oil will be administered orally once per day, as required for pain; or taken 4h before bedtime, if no pain. Primary objective: to determine the safety and tolerability of different formulations of Cannabis oil for pain in PD patients (incidence and severity of adverse events). Secondary objective: to assess change from the start of treatment (V2) to end of treatment (V5) in frequency and severity of pain, sleep, dystonia and motor symptoms in PD patients.
This study aimed to investigate the effects of dual-task training with exergame and treadmill on executive function and dual-task performance in individuals with PD and stroke and discuss the correlation between the change values of executive function and dual-task performance after training. Besides, investigate cortical activation after training.
This study evaluates the effect on Rock Steady Boxing (RSB) and PD SAFEx on Parkinson's disease.
Levodopa-carbidopa intestinal gel (LCIG) infusion has demonstrated to improve motor fluctuations. The aim of this study is to assess the long-term safety and effectiveness of LCIG infusion in advanced Parkinson's disease (PD) patients with motor fluctuations and its effect in non-motor symptoms.
Lingzhi(Ganoderma) is widely used in traditional Chinese medicine. Previous studies indicated that Lingzhi was safe, well tolorated, and improved symptoms as an add-on therapy to levodopa in early Parkinson's disease(PD) patients. Here the investigators design a multicenter, randomized, double-blind, placebo-controlled, delayed-start trial to evaluate the effects of Lingzhi on modifying disease progression in untreated PD patients.
The clinical phenotype of Parkinson's disease (PD) is quite variable, as is the response to and side effects from medications. While many patients respond to carbidopa/levodopa early on, motor fluctuations and dyskinesias can become a problem as the condition progresses, causing significant impairment in function and quality of life. The gut microbiome is of increasing interest in PD, potentially contributing to pathophysiology and clinical phenotype. Furthermore, gut bacteria are capable of metabolizing levodopa, which may decrease its ability to reach the central nervous system and could explain the variable effect seen clinically. Altering the population of drug-metabolizing bacteria could improve the clinical symptoms of PD and the benefit seen with medications. The investigators hypothesize that the gut microbiome in people with PD correlates with their phenotypic characteristics, which can be improved with targeting the microbiome through dietary or therapeutic interventions. The investigators propose a two-part clinical trial. First, a cross-sectional analysis will correlate the microbiome profile with (a) the clinical phenotype of PD and (b) medication response. Second, a randomized, controlled trial, will evaluate the effect of microbiome manipulation on clinical phenotype and medication response. The investigators plan to reduce the level of bacteria through antibiotic use, resetting the potentially disadvantageous microbiome population. Outcomes will include changes in clinical symptoms, alterations in the the microbiome, and changes in serum markers of inflammation. This thorough characterization will broaden our understanding of the gut-brain axis significantly in PD in clinically relevant ways that have yet to be explored.
Postural abnormalities represent disabling and painful complications in patients with Parkinson's disease (PD). The stooped posture is a typical feature of PD but with advancing of disease more severe body abnormalities can affect people with PD. These deformities include Pisa syndrome, camptocormia, antecollis, scoliosis and striatal deformities related to hand (striatal hand) and/or toes (striatal toes).
