Active clinical trials for "Parkinson Disease"

Parkinson's Disease (PD) is a neurodegenerative, progressive illness. It is a multi-system disease that influences not only the motor but also the cognitive and autonomic systems. The main cognitive impairment in individuals with PD is found in executive function (EF). EF is defined as a set of cognitive skills necessary for planning, monitoring and executing sequences of complex activities. The primary study hypothesis is that computer-based training aimed at improving executive function will have a beneficial effect on gait functions.

A trial to measure the effects of vitamin D (versus a placebo) on balance, gait, falls, strength, and cognition in persons with Parkinson's disease.

The purpose of the study is to assess the efficacy and safety of XP21279/Carbidopa in comparison to Sinemet as well as evaluate the pharmacokinetics (PK) of levodopa after administration of XP21279/Carbidopa and Sinemet and to explore exposure-response relationships in a subset of subjects.

This study is a fixed dose, dose response study to characterize the dose response for ropinirole PR in early stage PD patients (Hoehn & Yahr stages I-III). After screening and baseline assessments, subjects will be randomized to one of six final target treatment groups (placebo, 2, 4, 8, 12 or 24mg/day ropinirole PR). The study will consist of a screening period, an up-titration period, a maintenance period, a down titration period and a follow up period. This study utilizes change from baseline in the UPDRS motor score as the primary endpoint, in line with that used in the ropinirole PR monotherapy pivotal study (SK&F101468/168). Clinical review of the primary and secondary endpoints will be performed in order to establish the lowest maximally effective therapeutic dose.

The purpose of this study is to evaluate the efficacy and safety of two doses of safinamide (50 and 100 mg/day, p.o.), compared to placebo, as add-on therapy in patients with idiopathic Parkinson's disease with motor fluctuations who are currently receiving a stable dose of levodopa.

The objective of this trial is to define the minimum effective dose of BF 2.649 between 5 mg, 10 mg, 20 mg or 40 mg versus placebo in reducing the Excessive Daytime Sleepiness of Parkinson's disease patients

The aim of the study is to test the effects of low frequency deep rTMS using the novel H-coil on the motor, affective and cognitive deficits in patients with Parkinson's disease (PD) and to establish its safety in this population. The investigators anticipate to recruit 10 patients to an open pilot study. All patients will receive an active rTMS stimulation and will be given 12 treatment sessions, over a period of up to 4 weeks. Each of the 12 daily treatment sessions (lasting about 30 minutes each), will be consisted of 25 stimulation trains over the prefrontal cortex (20Hz trains, 2 seconds each with an inter-train interval of 20 seconds) and one train of 15 minutes at 1 Hz over the the motor cortex. The following outcome measures will be taken prior to the treatment (screening visit), and at day 1, 10, 30, 60, and 90: Unified Parkinson's Disease Rating Scale (UPDRS ) Clinical Global Impression of Severity (CGIS) Pegboard test. Tapping test Up & Go test Abnormal Involuntary Movement Scale (AIMS) Mood and affect Beck Depression Inventory (BDI) Cognition 1. Mini mental State examination (MMSE) 2. Digit forward and backward tests. 3. Word fluency. 4. Frontal Assessment Battery (FAB) Side effects will be closely monitored by the researchers and will be promptly reported to the IRB

The study will evaluate the safety and tolerability of ACR325 in Parkinson disease patients and evaluate the effect on levodopa induced dyskinesias.

Apathy usually refers to a set of behavioural, emotional and cognitive features as a reduced interest and participation in main activities of daily life, a lack of initiative, a trend toward an early withdrawal from started activities, an indifference and a flattening of affect. We have validated a new specific scale (Lille Apathy Rating Scale, LARS) in order to detect and quantify apathy in Parkinson's disease (PD). Apathy was shown to be frequent in PD with a prevalence of 32%. It has suggested that the medial frontal and limbic cholinergic deficits may underlie apathy in neurodegenerative disorders like Alzheimer's disease (AD). Such a hypothesis is supported by recent evidence indicating the beneficial effects of cholinesterase inhibitors on neuropsychiatric symptoms, mainly apathy, in AD patients. As the efficacy of rivastigmine on cognition has also been shown in PD, we aimed to assess with a randomized, double-blind, placebo-controlled, parallel-group, multicenter trial, the efficacy and acceptability of a 6 months treatment with rivastigmine on apathy in 60 patients with PD without dementia. The primary end point will be the LARS score and the secondary end points will be the cognitive, behavioural and motor symptoms of PD. Two add-on studies will be proposed: first the measure of choline and glutamate peaks on Magnetic Resonance Spectrometry focused on the structures implicated in apathy in order to give insights in the physiopathological mechanisms of the treatment. Secondly, the recording of the REM sleep behavior disorders in relation with the cholinergic part of the pedunculopontine nucleus. Regarding that apathy could be one of the first steps toward PD dementia, treating very early could have substantial implications on the patients and their caregiver.

To assess the efficacy of rasagiline 1 mg as a first add-on treatment to dopamine agonist therapy in early Parkinson Disease (PD) patients, , not optimally controlled on dopamine agonists as compared to placebo.
