Filter by:Parkinson's disease is a common progressive degenerative disease affecting 3% of all patients over the age of 65. Given their age and frailty, these patients frequently require surgical procedures with general anesthesia. However, after surgery, patients with Parkinson's disease have longer hospital stays and a greater chance of not returning to independent living compared to age-matched controls (Berman MF, unpublished data). In part, this is due to a higher rate of post-operative delirium, which had an incidence of 60% in this population in one study. There is anecdotal evidence from neurologists specializing in movement disorder suggesting that there is also significant deterioration in parkinsonian motor symptoms and cognition lasting for months or years following surgery and anesthesia. The basis for this deterioration is unknown. We hypothesize that these problems are caused by particular medications used during inhaled anesthesia for surgical procedures.
Retrospective review of records in the Emory Movement Disorders clinic suggests vitamin D deficiency occurs in over 80% of patients with Parkinson's Disease (PD), much more frequently than in internal medicine clinics. Laboratory studies have suggested vitamin D could play a role in the development of PD. In addition, low vitamin D levels have been associated with slower walking speeds, worse memory and thinking, and depression.
This is a two-arm, double-blind, placebo-controlled study.
This is an open, randomised, active-controlled, 2-period crossover study comparing the effect of single doses of Stalevo 200 and Sinemet on striatal (putamenal and caudate) 11C-raclopride BP in PD patients with wearing-off symptoms. The study consists of 4 visits: a screening visit (visit 1), 2 treatment periods (period 1=visit 2, period 2=visit 3) separated by a minimum wash-out period of at least 3 days, and an end-of-study visit (visit 4). Subjects will be randomly allocated to start the period 1 with a single dose of Stalevo 200 or Sinemet. After the wash-out the study drug on period 2 will be administered according to a crossover design.
The objective of this open-label extension is to assess the long-term effect of the 24-hour transdermal delivery of rotigotine on motor function, sleep quality, and nocturnal and non-motor symptoms of Parkinson's disease. The long-term safety and tolerability of the rotigotine transdermal patch will also be evaluated.
This is a multicentre, open-label extension study to evaluate the long-term safety, tolerability, and efficacy of Perampanel (E2007) as an adjunctive therapy in levodopa treated PD subjects with motor fluctuations. All subjects who have completed E2007-E044-213 or E2007-G000-309 will be candidates for entering this extension trial, provided that they meet the inclusion/exclusion criteria and have completed the core study, up to and including the final efficacy visit.
Patients with Parkinson's disease represent a significant proportion of VA elderly patients. Sleep disturbances and caregiver burnout association with this condition represent a significant problem. In this study, the investigators propose to perform an evaluation of a fixed doe of ramelteon on sleep in VA outpatients diagnosed with Parkinson's disease. The hypothesis to be examined is that ramelteon will improve the quality of sleep in patients with Parkinson's disease while indirectly improving the quality of life for the patients and caregivers. The investigators further hypothesize that these changes will occur through restructuring and normalization of the sleep architecture.
The purpose of this trial is to determine if the nutritional supplement creatine slows the progression of Parkinson's disease over time.
Phase IIb open-label extension study for patients with Parkinson's Disease. All patients will receive active study drug. The study will involve outpatient visits only. Patients who completed Study E2007-A001-214 (Cohorts I and II) and who meet inclusion/exclusion criteria will be enrolled and enter the 12-week Titration Phase (from "Dispense Study Drug" at Week 0 [Visit 2] through Week 12 [Visit 7]) followed by the Maintenance Phase (from Week 12 [Visit 7] to end of study).
Patients who have completed one of the core trials (E2007-E044-301 or E2007-A001-302) and who meet inclusion/exclusion criteria will be enrolled and will enter the Titration Phase, lasting 4 weeks (weeks 0-3) followed by the Maintenance Phase, lasting 52 weeks (weeks 4-56). All patients will receive active study drug. During the Titration Phase, patients will receive E2007 2 mg once daily (o.d.) for 2 weeks followed by 4 mg o.d. for 2 weeks. During the Maintenance Phase, patients will receive 4 mg o.d. Patients not tolerating the study drug at 4 mg, will be allowed to down titrate to 2 mg. Patients not tolerating 2 mg will be withdrawn from the study. Patients will have visits at 2, 4, 8, 20, 32, 44, and 56 weeks after study entry. In addition, a follow-up visit will occur 4 weeks after study treatment has ended (week 60). A home diary will be completed in which patients rate themselves as either: 1. OFF 2. ON without dyskinesia 3. ON with non-troublesome dyskinesias 4. ON with troublesome dyskinesias 5. Asleep These entries will be completed every half hour during the waking day and will be completed for 3 consecutive days following the visits at weeks 4, 8, 20, 32 and 44, and three days prior to the visits at weeks 56 and 60. At entry into the study (week 0) and at weeks 8, 20, 32, 44 and 56, the Unified Parkinson's Disease Rating Scale (UPDRS), Clinician's Global Impression of Change (CGIC) and Clinical Global Impression of Tolerance (CGIT) will be performed.
