Filter by:The purpose of this study is to explore the efficacy of the drug Amantadine for the treatment of freezing of gait in patients with Parkinson's Disease. The investigators hypothesize that amantadine is useful for management of freezing of gait in subjects with Parkinson's Disease.
A 48-month open label multi-centered extension study to evaluate the long-term safety, tolerability and efficacy of E2007 in patients with Parkinson's Disease with "wearing off" motor fluctuations and "on" period Dyskinesias.
The clinical and pathological similarities between LRRK2 related parkinsonism and idiopathic Parkinson's disease (PD) indicate that monogenetic LRRK2 parkinsonism may be a paradigm for the development of Lewy bodies disease, and a careful look at discrepancies between these two conditions may provide insight into the pathogenesis of PD. The early involvement of the enteric nervous system (ENS) during PD led to theories that an as yet unidentified external agent entering the ENS causes PD . If lesions of the ENS are found in patients who present with a genetic form of parkinsonism would go against this notion, and thus provide insight to the pathophysiology of the disease.
Parkinson's disease (PD) is a neurodegenerative disorder that is characterized with motor symptoms such as hypokinesia, rigidity, tremor and postural instability. These symptoms can also be present during the night. Half of the patients with PD have difficulty turning around in bed. This nocturnal hypokinesia is considered as a possible cause of sleep problems in this population. The diagnosis nocturnal hypokinesia is based on the clinical interview. There is a need for a diagnostic devices that measures nocturnal movements, preferably in the home setting. This device can be used in the diagnostic trajectory as well in the evaluation of treatment. Recently the Dynaport Minimod (McRoberts, The Hague) has been developed to register nocturnal movements. The tri-axial accelerometer has been developed to measure position changes in the night. A validation study with actigraphy and polysomnography concluded that the Dynaport MiniMod is a valid an feasible device for assessing intensity and physical activity and changes of body position during sleep. Nocturnal hypokinesia is treated with nocturnal dopamine. Sometimes a night-time dose of dopaminergics is adequate, but most of the time slow release dopaminergics are needed. However response fluctuations can negatively influence the treatment. In these cases continuous dopaminergic stimulation is needed, such as rotigotine. Rotigotine treats response fluctuations during the day and studies show that sleep quality measured with questionnaires improves. If the improvement of sleep quality is caused by improved bed mobility has not been studied yet. The study hypothesis is that rotigotine does not influence nocturnal hypokinesia in PD. Objective of the study: Primary: • To study the effect of rotigotine on nocturnal hypokinesia Secondary: - To study the possibility of measuring nocturnal hypokinesia and its severity in a home setting - To correlate improvements in sleep quality by rotigotine with changes in nocturnal hypokinesia Study design: We will study patients who will recieve rotigotine as a part of their usual care. During three nights, nocturnal movements are being registered with movement sensors, before treatment has started as well as after a stable medication dose of one month. We will also assess sleep quality with questionnaires. Study population: The study population are patients with Parkinson's disease with sleep problems caused by nocturnal hypokinesia, who will start treatment with rotigotine. Patients will be recruited in the neurology patient outdoor clinic of the Radboud University Medical Centre Nijmegen. We will ask the treating neurologist to inform us when a patient will start treatment with rotigotine. One of the researchers will contact the patient to give further information about the study. The study is a first hypothesis generating study and we will start with the inclusion of 10 patients. Intervention (if applicable): Primary study parameters/outcome of the study: Position changes over the night. Secundary study parameters/outcome of the study (if applicable): Objective - Degree of mobility, measured as the speed of the movements - Total amount of movements - Score on the motor symptom scale according to the MDS-UPDRS part III Subjective - Nocturnal sleep quality Excessive daytime sleepiness - Presence of nocturnal akinesia
Background: - Early-onset Parkinson's disease (EOPD) is more likely to be caused by gene mutations than Parkinson's disease that develops in older people. Studying these mutations may help find therapies for EOPD. Researchers want to study mutations on a gene called PARK2. These mutations prevent fat uptake into cells and may interfere with normal brain function. Researchers want to study fat and cholesterol in the body to look at the effects of these mutations on the body and brain. Objectives: - To study connections between genetic mutations and EOPD. Eligibility: - Individuals between 18 and 80 years of age with EOPD. - Individuals between 18 and 80 years of age with no family history of Parkinson s disease. Design: - Participants will be screened with a physical exam and medical history. Blood and urine samples will also be collected. - Participants will have some or all of the following tests: - Blood samples and tissue (skin and fat) biopsies - Cell line development from these tissue samples to study the function of PARK2 - DEXA scan to measure body fat context using low dose x-rays - Glucose and insulin tolerance testing to measure blood sugar levels. - Treatment will not be provided as part of this protocol.
The purpose of this study is to examine the ability of a structured physical activity program to improve sleep quality and daytime sleepiness in patients with Parkinson's disease.
The primary purpose is to demonstrate superiority of Rotigotine over Placebo on motor symptoms when used in subjects with symptoms of Gastrointestinal Dysfunction. Hypothesis: Rotigotine will decrease OFF time compared to Placebo.
This is a phase 4 study to evaluate with Polysomnography (PSG) and subjective measures the effect of Rotigotine on sleep efficiency, maintenance, insomnia, nocturnal akinesia and night-time movement in bed, in patients with advanced Parkinson's disease.
The Leucine-Rich Repeat Kinase 2 (LRRK2) is implicated in autosomal dominant Parkinson's disease (PKD). An inhibitor for the leucine-rich repeat kinase 2 (LRRK2) is in pre-clinical development for potential use in treating Parkinson's disease. Patients with PKD have cognitive impairments which develop alongside the typical motor symptoms but a full characterisation of the neurocognitive phenotype of PKD patients with LRRK2 mutation is currently lacking. This observational study conducted on a single visit will assess the phenotypic neurocognitive abnormalities of PKD patients with the LRRK2 mutation with the aim of identifying potential PD endpoints related to the LRRK2 mutation for future Phase I or II clinical trials of LRRK2 inhibitors.
The purpose of this observational study is the long term follow-up of Parkinson's patients who participated in a clinical trial in which they received AAV-GAD gene transfer into the subthalamic nucleus (STN) region of the brain. Patients will be followed once a year for up to five (5) years. The study will monitor and evaluate the long term effects of AAV-GAD and provide long term safety information.
