Active clinical trials for "Parkinson Disease"

Parkinson's disease patients usually have difficulty making automatic movements. Automatic movements are movements people often make without conscious thought. The purpose of this study is to investigate regions of the brain that affect automatic movements and to understand the movements of Parkinson's patients. Investigators hope this knowledge will lead to better treatment for the disease. Thirty participants will be enrolled in this study. Each will give a medical history and undergo a brief physical exam. Participants will have two MRI scans, each lasting approximately 1.5 hours. During these scans, they may be asked to move their right or left hands or to remember some letters that they have been shown. Before undergoing the second scan, participants will be asked to practice the tasks until they can perform them correctly.

In the study , the researchers will investigate the reliability and validity of Urdu version Parkinson's Disease Questionnaire in Pakistani population having Parkinsonism

The aim of this study is to implement home-based monitoring (HBM) using remote-capture wearable devices and patient reported outcomes (PROs) in a rather homogeneous subgroup of advanced Parkinson's Disease (PD) patients, suffering from significant motor fluctuations (MF) and Levodopa-induced dyskinesia (LID), over a two-week period. The investigators aim to provide a more comprehensive picture of patient symptoms, severity, and fluctuations and compare these data to interview-derived clinical data.

The investigators propose to study persons with Parkinson Disease (PD) with detailed clinical, cognitive and imaging at the time of study entry and repeat these assessments 2 years later. The study looks at how changes in activity of the neurotransmitter acetylcholine relates to changes in cognitive function and to see if there is presence or build up of amyloid protein.

This study is implemented to identify factors having an impact on improvement or exacerbation of non-motor symptoms, to provide information contributing to development of medical care in this field and improvement of patients' QOL, and to clarify the association between the use of istradefylline and non-motor symptoms or QOL.

Decreased muscle strength has been reported to be a factor contributing to increased incidences of falling in the elderly patients causing fractures, joint dislocations, severe soft tissue lesions and head trauma. Parkinson's Disease (PD) patients often complain of weakness and it has been reported that they have reduced muscle strength, decreased rate of force development, impaired ability to maintain constant force, and increased muscle coactivation during balance perturbation tasks. The specific cause of this weakness is not known, and in this study the investigators have analyzed and measured isokinetic muscle strength in PD patients to clarify this issue. The investigators have compared the data obtained with those of age-matched controls.

The objective is to assess a compact, portable, wireless movement disorder system with continuous monitoring capabilities to detect and quantify the severity of levodopa-induced dyskinesia in Parkinson's disease.

Parkinson's disease (PD) is one the main neurodegenerative disease with an incidence of about 3% in patients older than 65 years. Anesthesia in PD patients has been focused by several studies for concerning the interactive reaction between anesthetics and anti-Parkinsonian medication or Parkinsonian symptoms. However, our previous experience showed that the patients undergoing pulse generator placement were more prone to be involved in delayed emergence in the recovery room, which had been not reported yet. We speculated that PD patients might be a special population with abnormal pharmacodynamic characters of anesthetics, though no related evidence could be found to support this hypothesis. Therefore, in this project we investigated whether remifentanl requirement to inhibit patients' response to trachea intubation and skin insertion in PD patients undergoing DBS and pulse generator placement was different from non-PD patients undergoing intracranial surgery for reasons other than PD.

There is a growing trend in functional neurosurgery toward direct anatomical targeting for deep brain stimulation (DBS). This study describes a method and reports the initial experience placing DBS electrodes under general anesthesia without the use of microelectrode recordings (MER), using a portable head CT scanner to verify accuracy intra-operatively.

The objectives of this study are (1) to compare the clinical outcome in correlation with the electrode positions estimated by web-based image fusion of the preoperative MRI and the postoperative brain CT taken at a stable period after surgery using mutual information technique in the patients with advanced Parkinson's disease (PD) after bilateral STN DBS and (2) to examine whether the documentation of the electrode position by using mutual information technique at a stable period after unilateral or bilateral STN stimulation provides useful information for the postoperative programming.
